Vitamin E is also Antioxifant as α-tocopherol and is most commonly Body cleanse protocol aupplements wheat Dietary supplements for joint health and soybean oils. The Green tea antioxidant-rich recommends that Antiozidant should take fof to identify their skin type before choosing skin care products. Several studies, mostly performed in cell and animal models, have suggested beneficial effects of hydroxytyrosol in the prevention or treatment of chronic and degenerative diseases, especially CVD and cancer Facchini et al. Biogerontology 2, — What to know about antioxidants for skin.

Antioxidant supplements for aging -

This trial did not evidence any benefit from antioxidant supplementation on major CVD outcomes; moreover, vitamin E was associated with an increased risk of stroke Sesso et al. In a recent prospective study performed with 3, aged men, Wannamethee et al. Notably, whereas the dietary intake of vitamin C did not exert any influence, the dietary intake of vitamin E was significantly correlated with increased risk of HF Wannamethee et al.

The authors of this interesting investigation suggested that the reason for the association between vitamin E intake and HF might depend by the fact that vitamin E α-tocopherol may become a pro-oxidant in an environment characterized by high oxidative stress, such as an aged biological system Wannamethee et al.

Resveratrol appears to modulate numerous cell-signaling pathways through the regulation of different molecular targets including the AMP-regulated kinase AMPK and the NAD-dependent deacetylase Sirt-1 Yun et al. The variety of molecular mechanisms mediated by this compound translates into a plethora of biological actions, primarily, antioxidant and anti-inflammatory effects.

Resveratrol is a good antioxidant and blocks in vitro LDL oxidation, a biological phenomenon associated with the risk of coronary heart disease and myocardial infarction Khurana et al. In rodents, resveratrol supplementation has been shown to decrease cardiovascular risk factor, including blood lipids and VCAM-1, to improve cardiovascular function and physical capacity and to decrease inflammation in the vasculature of aged animals leading to improved vascular function Gliemann et al.

The anti-inflammatory properties of resveratrol have been proved by several in vitro experiments. For instance, resveratrol was showed to suppress NF-κB activity induced by beta-amyloid in PC12 neuron cell lines, Jang and Surh, and to reduce the production of IL-1 beta and TNF-alpha induced by LPS or beta-amyloid in the microglia Capiralla et al.

Resveratrol anti-inflammatory effect has been demonstrated also in vivo , i. Despite the promising results reported in vitro Zhang et al. Recent studies underlined the importance of patient selection in evaluating the potential therapeutic effects of resveratrol.

Recently, Carrizzo et al. Interestingly, resveratrol failed to exert any effect in vessels from patients without hypertension or dyslipidemia Carrizzo et al.

A differential effect of resveratrol influenced by the initial health status was also suggested by a recent meta-analysis by Liu et al. In a recent work published by Gliemann et al. In this trial 27 healthy physically inactive aged men were randomized into 8 weeks of daily intake of either mg of trans-resveratrol or of placebo and were subjected to concomitant high-intensity ET Gliemann et al.

The main aim of the study was to confirm if oral resveratrol supplementation improved the positive cardiovascular adaptations to ET in aged subjects by specifically increasing sirtuin 1 SIRT1 mediated signaling and by promoting the endogenous antioxidant system.

Interestingly, results showed that, whereas ET effectively improved several cardiovascular health parameters in aged men, concomitant resveratrol supplementation somehow blunted most of these effects leading, among others, to a significantly lower improvement in the training-induced increase in maximal oxygen uptake Gliemann et al.

Curcumin is a lipophilic bioactive phenol derived from the rhizome of Curcuma longa , which shows low solubility and stability in aqueous solution.

It is contained in culinary curry and used as a coloring agent in food Bhullar et al. Orally ingested curcumin is metabolized into the active metabolite tetrahydrocurcumin by a reductase found in the intestinal epithelium Sadowska-Bartosz and Bartosz, Extensive research during the last few decades has suggested a strong therapeutic and pharmacological potential of this molecule as antioxidant, antimutagenic, antiprotozoal and antibacterial agent Bhullar et al.

Curcumin strong medicinal properties are also associated with reported anti-cancer and neuroprotective effect such as in Alzheimer disease Brondino et al. A hormetic mechanism of action of this compound is suggested from studies showing that expression levels of the stress response protein Heme Oxygenase-1 HO-1 were increased in cultured hippocampal neurons treated with curcumin Scapagnini et al.

Moreover, this phenolic compound has been shown to reverse chronic stress-induced impairment of hippocampal neurogenesis and increase expression of brain-derived neurotrophic factor BDNF in an animal model of depression Xu et al. Several studies also showed that curcumin interacts with NF-κB, and through this interaction exerts protective function also in the regulation of T-cell-mediated immunity Kou et al.

Recently González-Reyes et al. In this study, a pretreatment of the neurons with 5—30 μM curcumin increased by 2. Furthermore, curcumin induced the translocation into the nucleus of nuclear factor related factor-2 Nrf2 , thereby stimulating an inflammatory and antioxidant response against hemin-induced neuronal death González-Reyes et al.

Curcumin effects on both the arterial endothelial function and the central arterial compliance was recently evaluated in post-menopausal women that underwent a daily ingestion of mg of curcumin Akazawa et al. In 32 post-menopausal women the Flow Mediated Dilation FMD measured arterial endothelial function, before and after 8 weeks of curcumin ingestion or ET.

After this time, the authors observed that FMD increased significantly both in the exercise and curcumin groups, whereas no significant change in FMD was detected in the control group Akazawa et al.

The results obtained suggested that a regular ingestion of curcumin could improve endothelial function and might be a potential alternative treatment for patients who are unable to exercise.

In a different study performed by the same group Akazawa et al. In this case also, the regular ingestion of curcumin, as the ET alone, significantly increased carotid arterial compliance in the group analyzed. Interestingly, the combination of ET and curcumin ingestion, differently from what observed with resveratrol Gliemann et al.

Hydroxytyrosol is an ortho-diphenol a catechol abundant in olive, fruits and extra virgin olive oil Waterman and Lockwood, This compound, due to its catecholic structure, shows a marked antioxidant activity and is able to scavenge oxygen and nitrogen free radicals, inhibit LDL oxidation, platelet aggregation and endothelial cell activation, and protects DNA from oxidative damage Waterman and Lockwood, ; Notomista et al.

Hydroxytyrosol is also a metal chelator and is able to scavenge the peroxyl radicals and break peroxidative chain reactions producing very stable resonance structures Bulotta et al. Interestingly, scavenging activity of hydroxytyrosol has also been demonstrated with respect to hypochlorous acid HOCl Visioli et al.

Moreover, it has been recently reported Giordano et al. The antioxidant activity of hydroxytyrosol seems to be related in vivo to its high bioavailability: various studies have in fact documented a high degree of absorption of this compound, which is fundamental to exert its biological activities Bulotta et al.

Several studies, mostly performed in cell and animal models, have suggested beneficial effects of hydroxytyrosol in the prevention or treatment of chronic and degenerative diseases, especially CVD and cancer Facchini et al. Most of the studies currently presented in literature on hydroxytyrosol are performed in vitro on cultured eukaryotic cells and very few are the clinical trials performed in humans and more specifically on elderly people.

One of the main reasons is probably the fact that purified hydroxytyrosol is still very expensive, which hampers its use for long-lasting trials.

Currently, the attention of the scientific community is focused more on the effect of olive oil supplementation on health, but olive oil is a complex mixture containing variable amounts of triacylglycerols, fatty acids and polyphenols Waterman and Lockwood, , thus no conclusive hypothesis of the use of purified hydroxytyrosol can yet be drawn from these studies.

Oliveras-López et al. After a 6-week s daily intake of polyphenol-rich olive oil with high oleuropein derivative contents, the authors found a significant improvement in lipid profiles, including a reduction of total cholesterol and a significant increase of HDL levels.

Moreover, in the same subjects, an increase of serum total antioxidant capacity, and a concomitant significant increase of catalase in erythrocytes and decrease in superoxide dismutase and glutathione peroxidase activities were also observed Oliveras-López et al.

The side chain serves to keep the molecule anchored in the inner mitochondrial membrane, and the quinone ring, which is easily and reversibly reduced to the quinol form, enables it to fulfill its function of transferring electrons from complexes I and II to complex III in the respiratory chain, ultimately resulting in the reduction of oxygen to water and the generation of ATP Nowicka and Kruk, ; Laredj et al.

CoQ10 is also capable of recycling and regenerating other antioxidants such as α-tocopherol and ascorbate. CoQ10 has also been identified as a modulator of gene expression, inflammatory processes and apoptosis Bhagavan and Chopra, The quinol prevents lipid peroxidation by inhibiting the initial formation and propagation of lipid peroxy radicals, and in the process it is oxidized to the quinone and H 2 O 2 is produced.

In addition, it has been shown to protect proteins from oxidation by a similar mechanism Forsmark-Andrée et al. As well as its role in the cellular membranes, CoQ is also believed to function in the blood to protect lipoproteins such as very low density VLDL , low density LDL and high density HDL lipoproteins from oxidation Bentinger et al.

Current evidence suggests that CoQ has a number of independent anti-inflammatory effects Schmelzer et al. It has been shown to reduce the secretion of pro-inflammatory cytokines in monocytes and lymphocytes after an inflammatory stimulus by influencing the expression of NF-κB-dependent genes Schmelzer et al.

Statins can effectively lower CoQ synthesis as they inhibit 3-hydroxymethylglutaryl Coenzyme A reductase HMG-CoA reductase , the rate-limiting enzyme in the pathway of cholesterol synthesis which includes the formation of the isoprenoid units required to produce CoQ Goldstein and Brown, Moreover, CoQ levels may be pathologically modified in conditions associated with oxidative stress and in aging Potgieter et al.

Data presented in literature on CoQ10 supplementation are heterogeneous and involve a very large number of pathologies. As for HF, no conclusions can be drawn on the benefits or harms of coenzyme Q10 as trials published in literature lack fundamental information concerning clinically relevant endpoints Madmani et al.

More in detail, reports on the effect of CoQ10 in diseases depending on oxidative stress in elderly people are scarce. In a recent study Bloomer et al. Treatment with CoQ10 resulted in a significant increase in total blood CoQ10 and reduced blood CoQ10, but did not translate into improved exercise performance or decreased oxidative stress Bloomer et al.

As previously reported, clinical trials involving the use of antioxidants supplementation often show conflicting results and lead to dangerous misconceptions, either too positive or too negative, on the use of these molecules in the treatment of several aging-associated diseases. Amid this debate, the first aspect that should be considered is that there are several limitations concerning FRTA, the basic hypothesis on which the antioxidants supplementation therapies are mainly based.

This theory, as already underlined, suggests a linear dose-response relationship between increasing amounts of ROS and biological damages, which potentially culminates in diseases and mortality. Therefore, oxidative stress should represent the main driving force of aging and a major determinant of lifespan Sadowska-Bartosz and Bartosz, The beneficial effects of caloric restriction CR and ET are a good example because they can be considered both as oxidative stressors or inducer of the endogenous antioxidant system activation by favoring a transient cellular increase of ROS Corbi et al.

Many independent investigations raised the possibility that an initial induction of ROS triggered by CR promotes an adaptive stimulation of antioxidant enzymes at the steady state, consequentially CR is now considered as the first example of mitohormesis Agarwal et al.

SIRT1, the first member of sirtuins characterized in humans, plays a crucial role in inducing mitochondrial biogenesis and mediating oxidative stress response through a number of proteins that promote the expression of antioxidant genes, such as peroxisome proliferator-activated receptor PPAR gamma coactivator-1 alpha 5 PGC-1α St-Pierre et al.

SIRT1 interacts with FOXO3a in cells in response to oxidative stress increasing FOXO3 ability to induce cell cycle arrest and resistance to oxidative stress and, at the same time inhibiting FOXO3 ability to induce cell death Brunet et al.

Ferrara et al. Exercise training, as CR, is to date considered an intervention triggering a cellular hormetic adaptation Radak et al. Physical inactivity is indeed one of the major risk factors for CVD, neurodegenerative disorders and many other diseases; consequentially, regular physical exercise exerts health promoting effect on such clinical conditions and in general on aging-related diseases Hu et al.

Exercise is strictly correlated to enhanced mitochondrial biogenesis and increased production of ROS and may promote longevity through pathways common to those of CR Lanza et al.

However, the benefits linked to ET strictly depend on the type and workload of exercise and, in particular, overtraining can result in maladaptation and possibly cellular damage Alessio and Goldfarb, ; Chevion et al. ET has been reported to activate PGC-1α, which controls mitochondrial gene expression by a variety of transcription factors Nikolaidis and Jamurtas, This regulation culminates in enhanced oxygen consumption in muscle fibers, which, in turn, promotes ROS generation.

Moreover, beyond skeletal muscle, other tissues, such as blood, heart and lung, represent a source of ROS during exercise Nikolaidis and Jamurtas, Concomitantly to enhanced ROS production, regular exercise leads to the up-regulation of several antioxidant enzymes, including SODs, catalase and glutathione peroxidase, reinforcing the concept that a certain amount of ROS is necessary for exercise health-promoting effects Nikolaidis and Jamurtas, It is not surprising, then, that both older and recent studies showed that purified antioxidants supplementation might be inadequate or even damaging for athletes, as they seem to abolish ET benefits, including prevention of certain diseases.

A very interesting study by Ristow et al. The authors measured insulin sensitivity by glucose infusion rate GIR and the amount of ROS within skeletal muscle of trained subjects previously untrained in the presence or absence of antioxidant supplementation with vitamin E and vitamin C.

As expected, ET induced ROS formation, which was counteracted by the antioxidant treatment. However, concomitantly to the increase of TBARs, ET was able to stimulate the expression of antioxidant molecules, such as SOD and GPx and induced an increase of GIR; these effects were also inhibited by antioxidants supplementation.

The conclusion of this study was that a transient increase of oxidative stress may contribute to prevent insulin resistance and type 2 diabetes and, most importantly, antioxidant supplementation may abrogate these results Ristow et al.

In addition to hormesis another aspect that should be considered for the conflicting results obtained in the clinical trials is the genetic background of the patients enrolled in the studies. In the last decade an increasing number of studies have suggested that longevity depends not only on life style habits but also on the genetic background.

Oxidative stress response is one of the most evolutionary conserved pathways involved in determination of lifespan from yeast to humans Vijg and Suh, ; vB Hjelmborg et al.

A GWAS authored by Major et al. The authors concluded that genetic variation contributes to the variability of serologic vitamin E status and may have potential application in determining the regimen of antioxidant supplementation required in complex diseases such as CVD and diabetes Major et al.

Very interesting data concern Haptoglobin Hp , a protein encoded by a polymorphic gene with 2 common alleles denoted 1 and 2, which counteracts the increase of ROS induced by hemoglobin activity Sadrzadeh et al. As previously reported, the HOPE trial, which investigated the potential protective effect of vitamin E in cardiovascular patients, showed that treatment with vitamin E had no effect on cardiovascular outcomes in patients at high risk for cardiovascular events Yusuf et al.

Later, Milman et al. To this end, the authors planned a prospective double-blinded clinical trial in a subgroup of individuals from the HOPE study with type 2 diabetes and found that vitamin E supplementation was effectively able to reduce cardiovascular events in patients with the Hp genotype Milman et al.

Other studies confirmed the impact of Hp genotyping in determining potential benefits from antioxidant therapy, and strongly supported the efficacy of a pharmacogenomic strategy to personalize and fine-tune the treatment with vitamin E in patients with type 2 diabetes Blum et al.

Redox state homeostasis in living systems is very complex and life style factors undeniably concur in determining the impact of changes in oxidative stress response in both unhealthy and healthy subjects. A large part of studies investigating the effectiveness of antioxidant supplementation therapy in humans raised contrasting results.

This is due to many aspects among which the often-limited statistic power of the studies, the patient genetic background, the bioavailability of the molecules used, and the non-specific effects that antioxidants might have in the human body, should be taken into account.

Mainly in the elderly, the clinical trials conducted so far often suffer from an incorrect initial selection of the patients. Further investigations should be planned to improve patients selection by performing, for example, quantitative characterizations of the redox state for each individual and taking into account both the individual patient demand and genetic background.

In addition it is worth to underline that, when dealing with either natural or synthetic antioxidants, clinical trials should consider other two important aspects. First, antioxidants bearing different functional moieties can be profoundly diverse in terms of chemical structure and mode of action; therefore, it should be recommended to identify the right antioxidant to treat a specific pathological condition Bast and Haenen, Secondly, the validity of the biomarkers used to determine the effects of antioxidants on human health are still under debate van Ommen et al.

This article discusses antioxidants and explains their function and benefits. It describes how they interact with the skin and lists antioxidants in foods, supplements, and skin care products. It explains how to choose a skin care product and cautions about potential drawbacks.

Antioxidants are substances that can prevent or delay some types of cell damage by counteracting free radicals and oxidative stress. A article explains that the body has exposure to oxidative stress as part of its metabolic activities and through environmental sources, such as pollution, tobacco, and alcohol.

Antioxidants can be synthetic or natural substances. They are present in fruits, vegetables, and supplements containing vitamins and minerals. Some substances, such as glutathione , are antioxidants that the body produces while others come from eating a healthy diet.

Antioxidants include the following :. Research indicates that scientists still do not know enough about how antioxidants work, as they can have adverse and beneficial effects. According to a review , antioxidants help protect the skin from harmful UV radiation, which can accelerate skin aging.

Antioxidants, such as carotenoids, are a vital part of the epidermis, and zinc is necessary for new cells to form. Selenium helps inhibit wrinkle formation, and vitamin E may protect against skin cancer. Antioxidants may improve the skin by :.

Antioxidants may also play a beneficial role in preventing skin conditions. For example, a review of 20 studies indicated that vitamin E levels were lower in patients with conditions, such as vitiligo , atopic dermatitis , and acne.

The reviewers highlight a need for further research to evaluate vitamin E for improving skin diseases. A review notes the potential of antioxidants to counteract the involvement of oxidative stress in psoriasis. Learn more about vitamin E for skin here.

A review suggests that the key antioxidants for skin health include:. While the review stresses the importance of diet, some of the antioxidants it mentions are available as supplements or in skin care products.

A popular antioxidant ingredient in skin care products is vitamin C. According to a review , vitamin C is the most abundant antioxidant in human skin. Even with high-dose oral supplements, only a fraction of vitamin C will be biologically available and active in the skin.

Therefore, topical vitamin C products may be a good option. The review notes that the topical application of vitamin C may have anti-aging and anti-pigmentation properties and protect from the effects of the sun.

Additionally, vitamin C replenishes vitamin E levels. The AAD recommends that people should take time to identify their skin type before choosing skin care products. If a person understands their skin type, it can help them find a suitable skin care routine and choose the right products.

The AAD also advises wearing sunscreen daily with an SPF of 30 or higher on all skin not covered by clothing. To save time, a person may wish to choose a moisturizer containing SPF. Retinoids are vitamin A-based products and include retinol. Retinol is a popular ingredient in skin care products and may improve uneven skin tone, pigmentation, and texture.

The AAD advises that products containing retinoids are a good option for people with mild acne or fine lines and wrinkles. However, the AAD recommends that people with skin allergies or dryness avoid retinoids.

Additionally, pregnant people must not use retinoid products, and those with hormonal acne should consult a dermatologist first. People who use retinoid products must use sunscreen, as they make the skin more sensitive to sun damage.

Find 15 of the best retinol creams for all skin types here. A study states that antioxidants may be valuable in skin care, both topically and orally. However, the author advises against using large doses for prolonged periods without seeking medical advice, as this may cause adverse effects.

The review also notes that despite many antioxidant skin care products being available, evidence varies regarding their impact on skin cells. Antioxidants are present in a wide range of foods.

The best food sources of antioxidants include :. Find a guide to antioxidant foods here. If someone has concerns about their skin health, they should speak with a doctor or dermatologist. Supplements contain antioxidants that may interact with medications doctors prescribe, so it is always best to check first before taking them.

Evidence suggests a connection between oxidative stress and conditions, such as acne and seborrheic dermatitis. However, no studies demonstrate the impact of antioxidants on these conditions.

Antioxidants work together in a complex manner. The most abundant antioxidant in the skin is vitamin C. Retinoids may be potent for people with certain skin conditions, such as acne.

The skin contains antioxidants, and the most abundant one is vitamin C.

In this Body cleanse protocol, we will discuss the Superfood supplement for muscle recovery of foe supplementation to improve health and longevity. Although many antioxidants are efficient free radical quenchers in vitro, their in vivo effects are less clear. Recent evidence from human trials implies that antioxidant supplements do not increase lifespan and can even increase the incidence of diseases. Synthetic antioxidants were unable to consistently prevent ROS-induced damage in vivo, possibly as dietary antioxidants may not act only as ROS scavengers.

Low serum vitamin D levels are common in sufferers of the painful condition rheumatoid arthritis. This condition is caused by inflammation. Vitamin D has beneficial immunomodulatory effects, so even low dose supplementation could enable the dose of conventional rheumatoid arthritis therapies to be reduced, with the consequent benefit of a reduction in side effects.

A very recent trial supports this hypothesis. A new paper using data from the DIAMOND DHA Intake And Measurement Of Neural Development study has shown that supplementation of infant formula with docosahexaenoic acid DHA and arachidonic acid ARA during the first year of life has a protective effect against allergy in early childhood.

The allergy status of the mother was shown to have a profound effect on the nature of the protection for the infant. A new study from Iran reports that patients with severe multiple sclerosis have lower blood vitamin D concentrations than patients with a milder form of the disease.

Antioxidants and ageing: harmless placebo or dangerous to your health? In this article Introduction A recently published systematic review So what do you tell your patients? Antioxidants table Reference In this article. Antioxidant supplements are unlikely to increase longevity. It is not necessary for a healthy individual to take antioxidant supplements. Excessive use of vitamins A and E and beta carotene may have a negative effect on lifespan. Fruit and vegetables containing antioxidants are not harmful. It is unknown if antioxidants have a role in the treatment of specific diseases or in specific patient groups, more research is needed. Antioxidants Vitamin A Vitamin A encompasses the retinoid group including retinol, retinal and retinoic acid. Vitamin A preparations may also be in the form of retinyl acetate or palmitate. Beta carotene Beta carotene is a precursor inactive form of vitamin A and is the substance in carrots that makes them orange. Vitamin E Vitamin E is also known as α-tocopherol and is most commonly sourced from wheat germ and soybean oils. Vitamin C Vitamin C is also known as L-ascorbate and occurs naturally in many fruits and vegetables. Selenium Selenium is a chemical element which occurs in different forms in the environment including as a trace element in soil. Other forms may be selenide salts or selenic acid.

You may also like Antioxidants help combat oxidative stress by donating an electron to the free radical, neutralizing it and preventing further damage. Some of the most well-known antioxidants for skin health include vitamins A, C, and E, as well as beta-carotene and selenium. These antioxidants are found in many foods, such as fruits and vegetables, nuts, and seeds. However, it can be difficult to get enough of these nutrients through diet alone, which is why many people choose to take antioxidant supplements which can help to support healthy, youthful-looking skin. Royal jelly is a thick, milky substance produced by worker bees to feed the queen bee. It is a rich source of nutrients, including vitamins , minerals, proteins, and antioxidants. Royal jelly has been used for centuries in traditional medicine to treat a variety of health conditions, including skin issues. Royal Happy Jelly has several potential benefits for skin health and anti-aging. It contains B vitamins , important for skin health, as well as amino acids, which are essential building blocks for proteins such as collagen and elastin. Collagen and elastin are important proteins that give skin its structure and elasticity. As we age, collagen and elastin production naturally decline, leading to wrinkles and sagging skin. By providing the necessary building blocks for collagen and elastin, royal jelly can help support overall skin health and reduce the signs of aging. In addition to its nutritional content, royal jelly also contains antioxidants such as flavonoids and phenolic acids. These compounds can help protect the skin from damage caused by free radicals and prevent oxidative stress. Oxidative stress can lead to cellular damage and contribute to aging, so protecting the skin from free radical damage is an important aspect of anti-aging skincare. Research has also suggested that royal jelly may have anti-inflammatory properties , which can benefit the skin. Inflammation is a common cause of skin issues such as acne, eczema, and psoriasis. By reducing inflammation, royal jelly may help improve the appearance of these skin conditions. Antioxidant supplements can help bridge the gap and ensure that the body has the nutrients it needs to support healthy skin and prevent aging. Vitamins and minerals are essential players in keeping your skin as healthy as possible and fighting the effects of aging. A multivitamin and mineral supplement can be a great way to ensure that you're getting all of the key nutrients you need for healthy skin and anti-aging. Diabetes can increase oxidative stress in the body, which can damage cells, including those in the skin. Diabetic multivitamin supplements are specially formulated to provide the nutrients that people with diabetes may be deficient in, including important antioxidants for the skin such as vitamin C , vitamin E, and selenium. These antioxidants work to neutralize free radicals and protect the skin from oxidative stress. Additionally, diabetic multivitamin supplements often contain nutrients and herbs that support healthy blood sugar levels, which can further benefit skin health. Green leafy vegetables can be an excellent source of nutrients for the skin, such as lutein, zeaxanthin, and beta-carotene, which are all antioxidants that can help protect the skin from sun damage and other environmental stressors. North Coast Naturals Ultimate Daily Greens is a superfood blend that provides a spectrum of nutrients from concentered and alkalizing super fruits, land, and sea greens with the addition of pre- and probiotic support. This supplement provides a wide range of antioxidants, including vitamin C, vitamin E, and carotenoids, which work together to protect the skin from oxidative stress and promote healthy, youthful-looking skin. Additionally, it contains enzymes and probiotics that support healthy digestion and nutrient absorption, which can further benefit skin health. In addition to taking antioxidant supplements, there are several other steps that people can take to support skin health and reduce the effects of aging. One of the most important is to protect the skin from sun damage, which is a major cause of premature aging, including wrinkles, age spots, and sagging skin. To protect the skin from sun damage , it's important to wear natural sunscreen with an SPF of at least 30, seek shade during peak sun hours, and wear protective clothing such as hats and long-sleeved shirts. Another important step is to avoid smoking and limit alcohol consumption. Smoking can damage collagen and elastin fibers in the skin, which can lead to premature aging. Alcohol can also dehydrate the skin and cause inflammation, which can contribute to wrinkles and other signs of aging. Maintaining a healthy diet that is rich in fruits, vegetables, whole grains, and lean protein is also essential for supporting skin health. These foods provide a wide range of nutrients that are important for healthy skin, including antioxidants, vitamins, and minerals. Additionally, staying hydrated by drinking plenty of water and avoiding sugary drinks can help keep the skin hydrated and prevent dryness and other skin issues. Finally, getting enough sleep is an important factor to consider when it comes to taking care of your skin. Lack of sleep is associated with increased signs of skin aging and can lead to dark circles under the eyes and a dull, tired-looking complexion 1. In conclusion, antioxidants play a crucial role in maintaining skin health and preventing premature aging. Antioxidant providing supplements, such as r oyal jelly, multivitamins and minerals, and greens powders, have been shown to reduce oxidative stress and may help to promote beautiful and youthful looking skin. However, it's important to note that while supplements can be helpful, they should not be relied on as the sole source of antioxidants in the diet. A balanced diet rich in fruits, vegetables, whole grains, and healthy fats is still the best way to ensure adequate intake of antioxidants and other essential nutrients. In addition to supplements and diet, other lifestyle factors such as regular exercise, stress management, and avoiding smoking and excessive alcohol consumption can also contribute to healthy skin and overall well-being.

Support The Nutrition Source	Drug Targets doi: Healthy food contains substances that have epigenetic effects , that reduce inflammation , that are beneficial to the gut microbiome, that do not overstimulate aging pathways like mTOR or insulin receptors , that improve mitochondrial functioning. Oxidants, antioxidants, and the degenerative diseases of aging. Jocelyn Solis-Moreira. To maintain an optimal level of this essential nutrient in their body, encourage your older ones to incorporate vitamin-C-rich foods, like fruits, vegetables, and legumes, into their diet, or consider taking supplements. The AAD recommends that people should take time to identify their skin type before choosing skin care products. It is a rich source of nutrients, including vitamins , minerals, proteins, and antioxidants.
8 Anti-Aging Vitamins and Nutrients That Actually Work, Ranked	A reduction in pore size, skin roughness and fine wrinkles, was seen by those in the treatment group at a significantly higher level than those taking the placebo, but there were no perceived changes in pigmentation levels. The supplement, taken once daily, contained antioxidants such as coenzyme Q10, beta-carotene , green tea extract and vitamin E acetate as well as minerals zinc and selenium. The researchers hypothesized that coenzyme Q10 helped fight oxidative damage preventing DNA degradation and collagen destruction. Low serum vitamin D levels are common in sufferers of the painful condition rheumatoid arthritis. This condition is caused by inflammation. Vitamin D has beneficial immunomodulatory effects, so even low dose supplementation could enable the dose of conventional rheumatoid arthritis therapies to be reduced, with the consequent benefit of a reduction in side effects. A very recent trial supports this hypothesis. A new paper using data from the DIAMOND DHA Intake And Measurement Of Neural Development study has shown that supplementation of infant formula with docosahexaenoic acid DHA and arachidonic acid ARA during the first year of life has a protective effect against allergy in early childhood. The allergy status of the mother was shown to have a profound effect on the nature of the protection for the infant. A new study from Iran reports that patients with severe multiple sclerosis have lower blood vitamin D concentrations than patients with a milder form of the disease. News New study supports antioxidant supplements for ageing skin. Published on. One of the main reasons is probably the fact that purified hydroxytyrosol is still very expensive, which hampers its use for long-lasting trials. Currently, the attention of the scientific community is focused more on the effect of olive oil supplementation on health, but olive oil is a complex mixture containing variable amounts of triacylglycerols, fatty acids and polyphenols Waterman and Lockwood, , thus no conclusive hypothesis of the use of purified hydroxytyrosol can yet be drawn from these studies. Oliveras-López et al. After a 6-week s daily intake of polyphenol-rich olive oil with high oleuropein derivative contents, the authors found a significant improvement in lipid profiles, including a reduction of total cholesterol and a significant increase of HDL levels. Moreover, in the same subjects, an increase of serum total antioxidant capacity, and a concomitant significant increase of catalase in erythrocytes and decrease in superoxide dismutase and glutathione peroxidase activities were also observed Oliveras-López et al. The side chain serves to keep the molecule anchored in the inner mitochondrial membrane, and the quinone ring, which is easily and reversibly reduced to the quinol form, enables it to fulfill its function of transferring electrons from complexes I and II to complex III in the respiratory chain, ultimately resulting in the reduction of oxygen to water and the generation of ATP Nowicka and Kruk, ; Laredj et al. CoQ10 is also capable of recycling and regenerating other antioxidants such as α-tocopherol and ascorbate. CoQ10 has also been identified as a modulator of gene expression, inflammatory processes and apoptosis Bhagavan and Chopra, The quinol prevents lipid peroxidation by inhibiting the initial formation and propagation of lipid peroxy radicals, and in the process it is oxidized to the quinone and H 2 O 2 is produced. In addition, it has been shown to protect proteins from oxidation by a similar mechanism Forsmark-Andrée et al. As well as its role in the cellular membranes, CoQ is also believed to function in the blood to protect lipoproteins such as very low density VLDL , low density LDL and high density HDL lipoproteins from oxidation Bentinger et al. Current evidence suggests that CoQ has a number of independent anti-inflammatory effects Schmelzer et al. It has been shown to reduce the secretion of pro-inflammatory cytokines in monocytes and lymphocytes after an inflammatory stimulus by influencing the expression of NF-κB-dependent genes Schmelzer et al. Statins can effectively lower CoQ synthesis as they inhibit 3-hydroxymethylglutaryl Coenzyme A reductase HMG-CoA reductase , the rate-limiting enzyme in the pathway of cholesterol synthesis which includes the formation of the isoprenoid units required to produce CoQ Goldstein and Brown, Moreover, CoQ levels may be pathologically modified in conditions associated with oxidative stress and in aging Potgieter et al. Data presented in literature on CoQ10 supplementation are heterogeneous and involve a very large number of pathologies. As for HF, no conclusions can be drawn on the benefits or harms of coenzyme Q10 as trials published in literature lack fundamental information concerning clinically relevant endpoints Madmani et al. More in detail, reports on the effect of CoQ10 in diseases depending on oxidative stress in elderly people are scarce. In a recent study Bloomer et al. Treatment with CoQ10 resulted in a significant increase in total blood CoQ10 and reduced blood CoQ10, but did not translate into improved exercise performance or decreased oxidative stress Bloomer et al. As previously reported, clinical trials involving the use of antioxidants supplementation often show conflicting results and lead to dangerous misconceptions, either too positive or too negative, on the use of these molecules in the treatment of several aging-associated diseases. Amid this debate, the first aspect that should be considered is that there are several limitations concerning FRTA, the basic hypothesis on which the antioxidants supplementation therapies are mainly based. This theory, as already underlined, suggests a linear dose-response relationship between increasing amounts of ROS and biological damages, which potentially culminates in diseases and mortality. Therefore, oxidative stress should represent the main driving force of aging and a major determinant of lifespan Sadowska-Bartosz and Bartosz, The beneficial effects of caloric restriction CR and ET are a good example because they can be considered both as oxidative stressors or inducer of the endogenous antioxidant system activation by favoring a transient cellular increase of ROS Corbi et al. Many independent investigations raised the possibility that an initial induction of ROS triggered by CR promotes an adaptive stimulation of antioxidant enzymes at the steady state, consequentially CR is now considered as the first example of mitohormesis Agarwal et al. SIRT1, the first member of sirtuins characterized in humans, plays a crucial role in inducing mitochondrial biogenesis and mediating oxidative stress response through a number of proteins that promote the expression of antioxidant genes, such as peroxisome proliferator-activated receptor PPAR gamma coactivator-1 alpha 5 PGC-1α St-Pierre et al. SIRT1 interacts with FOXO3a in cells in response to oxidative stress increasing FOXO3 ability to induce cell cycle arrest and resistance to oxidative stress and, at the same time inhibiting FOXO3 ability to induce cell death Brunet et al. Ferrara et al. Exercise training, as CR, is to date considered an intervention triggering a cellular hormetic adaptation Radak et al. Physical inactivity is indeed one of the major risk factors for CVD, neurodegenerative disorders and many other diseases; consequentially, regular physical exercise exerts health promoting effect on such clinical conditions and in general on aging-related diseases Hu et al. Exercise is strictly correlated to enhanced mitochondrial biogenesis and increased production of ROS and may promote longevity through pathways common to those of CR Lanza et al. However, the benefits linked to ET strictly depend on the type and workload of exercise and, in particular, overtraining can result in maladaptation and possibly cellular damage Alessio and Goldfarb, ; Chevion et al. ET has been reported to activate PGC-1α, which controls mitochondrial gene expression by a variety of transcription factors Nikolaidis and Jamurtas, This regulation culminates in enhanced oxygen consumption in muscle fibers, which, in turn, promotes ROS generation. Moreover, beyond skeletal muscle, other tissues, such as blood, heart and lung, represent a source of ROS during exercise Nikolaidis and Jamurtas, Concomitantly to enhanced ROS production, regular exercise leads to the up-regulation of several antioxidant enzymes, including SODs, catalase and glutathione peroxidase, reinforcing the concept that a certain amount of ROS is necessary for exercise health-promoting effects Nikolaidis and Jamurtas, It is not surprising, then, that both older and recent studies showed that purified antioxidants supplementation might be inadequate or even damaging for athletes, as they seem to abolish ET benefits, including prevention of certain diseases. A very interesting study by Ristow et al. The authors measured insulin sensitivity by glucose infusion rate GIR and the amount of ROS within skeletal muscle of trained subjects previously untrained in the presence or absence of antioxidant supplementation with vitamin E and vitamin C. As expected, ET induced ROS formation, which was counteracted by the antioxidant treatment. However, concomitantly to the increase of TBARs, ET was able to stimulate the expression of antioxidant molecules, such as SOD and GPx and induced an increase of GIR; these effects were also inhibited by antioxidants supplementation. The conclusion of this study was that a transient increase of oxidative stress may contribute to prevent insulin resistance and type 2 diabetes and, most importantly, antioxidant supplementation may abrogate these results Ristow et al. In addition to hormesis another aspect that should be considered for the conflicting results obtained in the clinical trials is the genetic background of the patients enrolled in the studies. In the last decade an increasing number of studies have suggested that longevity depends not only on life style habits but also on the genetic background. Oxidative stress response is one of the most evolutionary conserved pathways involved in determination of lifespan from yeast to humans Vijg and Suh, ; vB Hjelmborg et al. A GWAS authored by Major et al. The authors concluded that genetic variation contributes to the variability of serologic vitamin E status and may have potential application in determining the regimen of antioxidant supplementation required in complex diseases such as CVD and diabetes Major et al. Very interesting data concern Haptoglobin Hp , a protein encoded by a polymorphic gene with 2 common alleles denoted 1 and 2, which counteracts the increase of ROS induced by hemoglobin activity Sadrzadeh et al. As previously reported, the HOPE trial, which investigated the potential protective effect of vitamin E in cardiovascular patients, showed that treatment with vitamin E had no effect on cardiovascular outcomes in patients at high risk for cardiovascular events Yusuf et al. Later, Milman et al. To this end, the authors planned a prospective double-blinded clinical trial in a subgroup of individuals from the HOPE study with type 2 diabetes and found that vitamin E supplementation was effectively able to reduce cardiovascular events in patients with the Hp genotype Milman et al. Other studies confirmed the impact of Hp genotyping in determining potential benefits from antioxidant therapy, and strongly supported the efficacy of a pharmacogenomic strategy to personalize and fine-tune the treatment with vitamin E in patients with type 2 diabetes Blum et al. Redox state homeostasis in living systems is very complex and life style factors undeniably concur in determining the impact of changes in oxidative stress response in both unhealthy and healthy subjects. A large part of studies investigating the effectiveness of antioxidant supplementation therapy in humans raised contrasting results. This is due to many aspects among which the often-limited statistic power of the studies, the patient genetic background, the bioavailability of the molecules used, and the non-specific effects that antioxidants might have in the human body, should be taken into account. Mainly in the elderly, the clinical trials conducted so far often suffer from an incorrect initial selection of the patients. Further investigations should be planned to improve patients selection by performing, for example, quantitative characterizations of the redox state for each individual and taking into account both the individual patient demand and genetic background. In addition it is worth to underline that, when dealing with either natural or synthetic antioxidants, clinical trials should consider other two important aspects. First, antioxidants bearing different functional moieties can be profoundly diverse in terms of chemical structure and mode of action; therefore, it should be recommended to identify the right antioxidant to treat a specific pathological condition Bast and Haenen, Secondly, the validity of the biomarkers used to determine the effects of antioxidants on human health are still under debate van Ommen et al. VC, VI, and GC conceived and designed the review and wrote the paper; GR and VM performed the bibliographic research; FD and AD edited the manuscript; AF contributed to write the paper. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Abdala-Valencia, H.
