Alphaa-lipoic the moment, Adid said, that's not the way things appear Alpha-lipoic acid and aging be headed -- diabetes is skyrocketing, about 50 percent of people over ahd have high blood pressure, heart disease often leads to permanent disability, and almost half of the elderly people in America have malnutrition that is easily preventable.
No single intervention can address all of these issues, Hagen said, but one that scientists keep coming back to is lipoic acid.
What the OSU researchers now believe is that the role of lipoic acid is not so much a direct one to benefit cells, but rather an indirect aid that "kick starts" declining function in cells and helps them recover the functions that came more easily and naturally in young animals.
In various effects, lipoic acid appears to help restore a cellular "signaling" process that tends to break down in older blood vessels. It reduces mitochondrial decay in cells, which is closely linked to the symptoms of aging.
With age, glutathione levels naturally decline, making older animals more susceptible to both free radicals and other environmental toxins -- but lipoic acid can restore glutathione function to near normal.
And the expression and function of other genes seems to come back to life. Many other presentations have been made at this conference on the role of diet, lifestyle and micronutrients in health and degenerative disease, including cancer, heart disease, neurological diseases and aging.

| Can α-Lipoic Acid Mitigate Progression of Aging-Related Decline Caused by Oxidative Stress? | SMJ | Anxioxidant activities of dithiol alpha-lipoic acid. Bioavailability is the percentage of a nutrient that enters the bloodstream compared to how much was in the supplement. Lipoic acid can also be used in supplements in some cases such as fat burning, improvement in metabolism, blood glucose control, collagen production , etc. Notably, the production of glutathione declines with age. Age-related diseases result from oxidative stress, inflammation, mitochondrial dysfunction, or DNA damage. However, no fatal side effects have been reported with adults taking up to mg.

Alpha-lipoic acid and aging -
Hence, no definitive conclusion can be reached from these small studies. Instead, there is a need to conduct more extensive clinical trials to confirm the results of these smaller studies. Since ALA has been shown to pass the blood-brain barrier easily, it is thought to protect nerve tissue and the brain from the onslaught of free radicals.
Researchers are exploring whether ALA can help with brain damage and strokes. Some of these brain problems associated with free radical damage include dementia.
Dementia is an umbrella term for neurological conditions affecting cognition, memory, and physical functioning. So far, evidence of the effectiveness of ALA therapy on brain function and stroke is not yet available.
Determining if ALA effectively treats brain disorders or other neurological disorders and strokes would be difficult. The effects of ALA on brain function and stroke will require large clinical trials in the future.
Symptoms of this condition start slowly. Hence, individuals may not notice these symptoms over time. A comprehensive dilated eye exam is necessary to diagnose glaucoma [ 3 ]. An updated review [ 4 ] on how antioxidants such as ALA may potentially treat glaucoma revealed that in animal model studies, ALA was shown to protect retinal ganglion cells from ischemic damage.
ALA likewise increased the expression of proteins and antioxidant genes that protected retinal ganglion cells against oxidative damage. To date, there are still no human clinical trials examining the effectiveness of ALA in treating glaucoma and protecting retinal ganglion cells against oxidative and ischemic damage.
However, animal model studies suggest that ALA may treat glaucoma. Preliminary studies suggest that ALA may help reduce fine lines in the face due to damage from sun exposure. Other conditions that ALA may treat can include cancer and erectile dysfunction. However, there still needs to be human clinical trials examining the effectiveness of ALA in treating these conditions.
Instead, only animal model studies have shown that ALA may potentially treat cancer and erectile dysfunction. Alpha lipoic acid is produced naturally in the body.
Alpha lipoic acid is available as supplements in capsule forms. Talk to your healthcare provider if you are planning to take these supplements. Finally, alpha lipoic acid is a potent antioxidant naturally produced in the body.
Supplementation with this antioxidant may yield numerous benefits, including delaying aging and promoting overall health and well-being. However, most of the studies backing up these claims came from animal model studies or human studies with small sample sizes and poorly designed studies.
The lack of large clinical trials to support these claims should be considered when taking these supplements.
Despite the lack of large clinical trials, ALA has not been shown to lead to toxic effects when taken at the recommended daily dosage. Hence, seeking medical advice from your healthcare provider would help you make healthy choices for your health.

To find out more about alpha-lipoic acid and how it can reduce neuropathy discomfort, watch this video from Dr. Like the rings on the stump of a tree, fine lines and wrinkles become more visible with age. Even though aging is an inevitable process, nature has gifted us with alpha-lipoic acid.
Results from a human study revealed using alpha-lipoic acid as a topical cream helped in a significant reduction of facial lines and general improvement in skin color and texture. And to cap it all, there were no associated side effects like irritation and peeling.
Moreover, as mentioned earlier, ALA increases the levels of glutathione and helps keep this antioxidant at optimum levels, further protecting our skin from damage and reducing signs of aging skin. Interestingly, a small pilot study found that when alpha-lipoic acid was taken with omega-3 fatty acids, the participants experienced no cognitive or functional decline.
A larger study is needed to further evaluate this combination, but the researchers deemed it to be a potential treatment for this condition. Did you know that Krill Oil is a powerful source of omega-3 fatty acids? It also comes without the unpleasant side effect of a fishy aftertaste.

Alpha-lipoic acid does not only help with diabetic neuropathy but also shows potential in slowing carpal tunnel syndrome. Carpal tunnel syndrome is a common condition that causes nerve pain, numbness, and tingling in the arm. It occurs when the median nerve is compressed as it travels through the wrist or carpal tunnel.
Rates of developing carpal tunnel syndrome increase with age. Nevertheless, alpha-lipoic acid may help remedy this condition. The supplement, when taken before and after surgery for the syndrome , has contributed to higher chances of recovery.
In light of that, the supplement, when used with gamma-linolenic acid , has shown to improve function in people with carpal tunnel syndrome. Research is also currently underway to assess if ALA can help sufferers of multiple sclerosis.
Pilot studies suggest that it has great potential to help with this condition and further research is needed. Infections in the upper respiratory tract could lead to loss of the sense of smell. Alpha-lipoic acid has been found to have therapeutic effects on olfactory loss.
Making use of its anti-oxidative effects on nerves, the acid could help in the regeneration of olfactory receptor neurons.
In the wake of the COVID, recent findings are showing the condition can affect our sense of smell. And, while the remedies for the novel virus remain in development, alpha-lipoic acid may be an option when these symptoms affect our olfactory pathways.
Alpha-lipoic acid also shows potential in helping weight loss and managing obesity. This is thought to be because of its role in energy production, regulating insulin, and reducing inflammation.
In a meta-analysis of randomized controlled trials, it was found that treatment with alpha-lipoic supplements resulted in a significant 1.
The researchers concluded that ALA showed small, yet significant, short-term weight loss and that further research was needed on varying doses and the use of ALA for long-term management of weight.
Those who took lipoic acid, also showed lower levels of inflammatory markers and damage from free radicals. Even so, some may experience mild symptoms like rashes, itching, or nausea.
There has not been sufficient research conducted on the use of the supplement for children, pregnant or breastfeeding women.
Additionally, for those with diabetes, seeking medical advice is vital, as alpha-lipoic acid may affect other medicines that help lower blood sugar levels. However, no fatal side effects have been reported with adults taking up to mg.
Bioavailability is the percentage of a nutrient that enters the bloodstream compared to how much was in the supplement. However, liposomal supplements have a bioavailability that is close to that of IV delivery, and therefore, using a high-quality liposomal alpha-lipoic acid supplement is best.
R-alpha-lipoic acid is a potent form of ALA that is more biologically active and has stronger antioxidant and brain-protecting benefits. A study by Zaitone et al. In reserpine-treated rats, LA enhanced the amount of GSH, while diminishing GSSG levels in the striatum. Moreover, LA decreased NO concentrations in striatum and pre-frontal cortex, without significantly affecting S-nitrosothiol levels.
LA also increased enzymatic activities of GPx and GST in the striatum Bilska et al. Reserpine significantly decreased enzymatic activity of L-γ-glutamyl transpeptidase γ-GT , while pretreatment with LA was able to restore it.
The effects of LA on oxidative stress in rotenone parkinsonian rat brains were investigated, showing that LA can reduce lipid peroxidation and protein carbonylation Zaitone et al.
LA also lowered the levels of MDA and nitrite in the 6-OHDA-induced rat model of hemi-parkinsonism Jalali-Nadoushan and Roghani, Karunakaran et al. R-LA induced significant reductions in markers of oxidative modifications in transgenic AD mice model, significantly decreasing HO-1 and protein-bound HNE levels Siedlak et al.
Inman et al. The results showed that after 4 and 11 months of dietary LA, respectively, LA treatment increased antioxidant genes and protein expression, protected retinal ganglion cell RGC , and improved retrograde transport.
Dietary therapy also reduced lipid peroxidation, protein nitrosylation, and DNA oxidation in a retina model of glaucoma.
Accumulation of metal ions also has been associated with increased oxidative stress related with aging and neurodegenerative disorders.
Suh et al. However, Liu et al. There are multiple cell death mechanisms implicated in neurodegeneration. Apoptosis is a highly controlled cellular process that can be activated by two pathways: extrinsic, which is a receptor-mediated pathway, and intrinsic, which is mediated by signals from the mitochondria.
Both pathways culminate at cleavage-dependent activation of aspartate-specific effector caspases caspases-3, 6, and 7. Manda et al. They observed that pre-treatment with LA prevented radiation-induced decreases of total, nonprotein and protein-bound sulfhydryl T-SH, NP-SH, and PB-SH levels in the cerebellum.
Moreover, LA treatment also improved the cytoarchitecture of cerebellum, increasing the number of intact Purkinje cells and granular cells when compared to untreated irradiated mice. Mehrotra et al. The results showed that LA decreased malondialdehyde, protein carbonyls, reactive oxygen species and nitrite levels, and increased Mn-superoxide dismutase and CAT activity.
LA improved activity of enzymes from the mitochondrial respiratory chain, altered cytochrome levels, increased histochemical staining of complex-II and IV, increased in-gel activity of complex-I to V, and increased mRNA expression of respiratory chain complexes. Stoll et al. The results showed that LA improved age-related NMDA receptor deficits B max.
No changes were observed regarding muscarinic, benzodiazepine, and α 2 -adrenergic receptor deficiencies. Thus, the authors concluded that LA-induced memory improving effects may be related to partial reparation of NMDA receptor deficits that accompany aging. A loss of dopaminergic neurons is particularly relevant to PD, in which genetic and environmental factors are involved Di Domenico et al.
Jalali-Nadoushana and Roghania using a rat model of hemi-parkinsonism 6-OHDA found that LA prevented neuronal loss on the left side of the substantia nigra pars compacta SNpc Jalali-Nadoushan and Roghani, In a study using the LPS-induced inflammatory PD model, Li et al.
Zaitone et al. Li et al. Moreover, the authors showed that LA inhibited the stimulation of nuclear factor-κB NF-κB and expression of pro-inflammatory molecules in M1 microglia. The results showed that LA significantly decreased rotenone-induced mtDNA damage. Liu et al. Dietary administration of LA significantly reduced oxidized RNA levels and reversed mitochondrial structural deterioration induced by aging in the hippocampus.
Dwivedi et al. The results indicated that arsenic and dichlorvos induced oxidative stress and cholinergic dysfunction in brain, which was significantly protected by the supplementation with LA. Seidman et al. Their results showed that mtDNA deletions associated with aging were reduced by LA and this effect appeared to be related to the mitochondrial capacity to protect and repair mtDNA against age-induced injury.
Palaniappan and Dai investigated the effect of LA administration to aged rats and verified a reduction of mitochondrial lipid peroxidation, 8-oxo-dG and oxidized glutathione GSSG and increased GSH, ATP, and electron transport chain ETC complex activities in the brain. The SAMP8 mouse strain is an experimental model that displays increased oxidative stress accompanied by memory decline associated to a rapid aging process.
In order to determine the mechanisms underlying LA-induced reversion of memory deficits exhibited by SAMP8 mice, Poon et al. The levels of three proteins neurofilament triplet L protein, a-enolase, and ubiquitous mitochondrial creatine kinase were significantly increased, while protein carbonylation was reduced in lactate dehydrogenase B, dihydropyrimidinase-like protein 2, and a-enolase in aged SAMP8 mice that received LA, suggesting that, in addition to improving learning and memory, LA also can restore specific proteins in aged SAMP8 mouse brain.
Evidence indicates that deregulation in neurotransmitter systems, including decreased levels of neurotransmitters, decline in the number of receptors, and lower responsiveness to neurotransmitters can be key features of neurological disorders Payton et al.
Arivazhagan and Panneerselvam investigated the effect of LA on levels of neurotransmitters dopamine, serotonin, and norepinephrine , and showed that LA treatment can improve neurotransmitter function in models of neurodegenerative diseases. Jesudason et al. The results showed that AD mice treated with LA exhibited enhanced levels of serotonin, dopamine, and norepinephrine, and the concentration of metabolites 5-hydroxyindole acetic acid 5-HIAA and homovanillic acid HVA gradually returned to normal.
Ahmed explored the effect of LA on brain acetylcholinesterase AChE activity. The authors demonstrated that LA can ameliorate neurological injury related to Aβ and Al excess, by significantly restoring AChE activity.
In addition, the authors showed that the treatment with LA restored the parameters of total homocysteine tHcy , insulin, insulin like growth factor-1 IGF-1 , interlukin-1β IL-1β and tumor necrosis factor-α TNF-α.
Mahboob et al. LA treatment increased the expression of muscarinic receptor genes M1, M2 and choline acetyltransferase ChaT relative to AlCl 3 -treated group. There are many studies examining the neuroprotective actions of LA using in vitro models of neurodegeneration Tirosh et al.
For example, Ono et al. The results showed that both LA and DHLA inhibited fAβ formation from amyloid β, as well as their expansion, and undermined preformed fAβs in a dose dependent manner.
Lovell et al. In β-amyloid-intoxicated C6 glioma cells, LA increased cell viability and MnSOD expression. The increased GSSH and decreased GSH mitochondrial levels induced by Aβ were reversed by treatment with LA Xing et al. The study by Deuther-Conrad et al.
de Arriba et al. Tirosh et al. Kamarudin et al. Suppression of NF-κβ p65 translocation and production of proinflammatory cytokines IL-6 and TNF-α followed inhibition of cleaved caspase Yamada et al. They showed that all types of LAs were effective in preventing cell death.
R-LA and S-LA also enhanced expression of genes related to anti-oxidative response such as heme oxygenase-1 HO-1 and phase II detoxification enzymes such as NAD P H:Quinone Oxidoreductase 1 NQO1. Other studies evaluated the effect of LA on in vitro model of PD. Moreover, Zhang et al. LA has been proposed to exert a modulatory control on the cellular redox status.
Due to its ability to be interconverted in one of its two forms—i. LA has been described to regenerate other antioxidants, such as vitamin C and E, to increase GSH levels, and to provide modulation of proteins and transcription factors Packer et al.
Extracellular redox state is also regulated by LA, once its reduced form, DHLA, can interact with cystine, reducing it to cysteine, thereby stimulating its uptake by the cell, which in turn stimulates GSH synthesis Han et al.
For instance, Jiang et al. Prevention of sevoflurane-induced apoptosis by LA was accomplished through recovery of Akt and GSK3-β phosphorylation levels in the hippocampus Ma et al. Sancheti et al.
Compelling evidence indicates that LA displays memory-ameliorating properties in a variety of experimental models of neurodegenerative diseases, as well as in memory decline associated with aging in rodents. Studies aiming to assess the neuroprotective effects of LA on behavioral outcomes showed that LA can reduce memory deficits in different behavioral paradigms on AD Quinn et al.
In humans, two studies in AD patients have supported the positive cognitive effects of LA Hager et al. Many studies reported beneficial effects of LA in the rat brain or neuronal cell cultures, using different molecular markers of oxidative stress, such as reduction in the levels of lipid peroxides and protein carbonyls, recycling endogenous antioxidants such as vitamin C and E, increasing glutathione levels Packer et al.
LA was also shown to display anti-inflammatory properties Deuther-Conrad et al. In vivo and in vitro studies showed that LA ameliorated neurodegeneration in the hippocampus, decreasing neuronal apoptosis and caspase-3 protein levels, supporting a neuroprotective role mediated by the mitochondrial cell death pathway.
These effects suggest that LA is able to improve mitochondrial dysfunctions. Interestingly, in addition to decreasing neuronal cell death, LA also inhibited fAβ formation from amyloid β-protein, ameliorating the neurological damage induced by Aβ, and significantly restored AChE activity.
This evidence suggests that LA presents a potential role in enhancing cholinergic and cognitive functions. These neuroprotective effects may be related to the properties of LA in ameliorating memory loss associated to neurodegenerative diseases.
Remarkably, LA was able to reverse age-associated glutamatergic NMDA receptor deficits Stoll et al. LA was also shown to improve the function of neurotransmitter systems, including dopamine, serotonin, and norepinephrine.
Taken together, these findings provide evidence that LA can reverse loss of neurotransmitters, their receptors and responsiveness to neurotransmitters, which can underlie its effects on cognitive functions.
In summary, this review has described and discussed relevant studies investigating the effects of LA on cognition as well as its cellular and molecular effects, aiming to improve the understanding of the therapeutic potential of LA in memory loss during aging and patients suffering from neurodegenerative disorders.
Although the mechanisms of action of LA are not fully understood, multiple pathways are likely to be involved in its neuroprotective properties. The memory-improving effects and neuroprotective actions of LA support its use as an adjuvant treatment for neurodegenerative disorders.

Alpha-lipoic acod, also known as thioctic acid or lipoic acidis a naturally occurring compound that is synthesized in animals and plants. Alpha-lipoic acid is a unique antioxidant in that it is both hydrophobic and hydrophilic. This means it dissolves in both water and fat, which makes it accessible to every cell and tissue in the body. As far as we know, lipoic acid seems to be used in several cellular processes, but as with many molecules, research is ongoing. Here are some of the ways that our bodies use lipoic acid.
Mir ist es nicht klar
Ich denke, dass Sie sich irren. Ich biete es an, zu besprechen. Schreiben Sie mir in PM.
Welche gute Gesprächspartner:)
