Following a well-balanced diet rich in nutrient-dense foods like fruits, vegetables, healthy fats and protein foods can provide all of the vitamins for skin and hair that your body needs and can be even more effective than even the best supplements.

Try squeezing in a serving or two of fruits and veggies into each meal or swapping out your favorite salty snacks for a few nutrient-packed superfoods instead. To cram in even more vitamins for clear skin into your diet, start your morning with a power-packed smoothie, and fill it with your choice of greens and berries, plus a scoop of collagen or bone broth to bump up the benefits a bit.

Unfortunately, not all supplements are created equal, and many are often pumped full of fillers, additives and preservatives, which are added by the supplement industry in favor of profit rather than health. Certain supplements for skin can actually come with negative side effects if used in high amounts, so use as directed, and be sure to consult with your doctor if you have any questions or concerns.

Believe it or not, scientists have only recently begun to understand the integral role that vitamins play in overall health, and the powerful influence that they have on skin health has just started to come to light within the last century. The discovery of vitamins can be traced back to Polish biochemist Casimir Funk, who isolated a specific compound later identified as niacin that was found in brown rice and was able to prevent B vitamin deficiency symptoms.

This soon led to the discovery of other vitamins essential to skin health, including vitamin E in and vitamins A and C in Researchers started wondering what vitamins are good for your skin and began conducting experiments to understand the complex role between nutrition and skin health.

In , the first study using retinoic acid, a derivative of vitamin A, to treat acne was published, and just a decade later, it had become a widely used tool to help treat breakouts. Studies have continued to emerge in recent years in an effort to understand exactly how certain vitamins, minerals and supplements can affect different aspects of skin health, including hydration, aging, acne and the treatment of specific skin conditions.

To achieve maximum results, supplements should always be paired with a healthy, well-rounded diet filled with nutrient-dense foods. If you have any underlying health conditions, check with your doctor before starting supplementation, as some supplements may not be safe for certain health conditions and could also potentially interfere with medications.

Finally, be sure to start with a low dose and slowly work your way up to assess your tolerance, but never go above the recommended dosage listed on your supplement.

If you experience any adverse side effects, consider decreasing your dosage and discuss with your doctor to address any concerns. Popular Nutrition Posts All Time This Week {position} Detox Your Liver: A 6-Step Liver Cleanse.

Vitamin C aids in collagen production and UV skin protection. Olly Undeniable Beauty Hair, Skin and Nails vitamins contain a large dose of biotin at 2, mcg.

I was also glad to see 50 mg keratin included in the Olly Undeniable Beauty vitamin. Keratin is the basic component in our hair, skin and nails.

While the research into the effectiveness of taking additional keratin supplements is lacking, it's a good option for people with a keratin deficiency. Olly is naturally flavored and colored with sweet potatoes, apples, cherries, radish, carrot and blueberry juices.

Reviews of Olly suggest these grapefruit-flavored gummies taste good. I like Olly because of the depth of the product line.

If you're looking for a vitamin that only targets hair or nail health, you have that option. Note that some reviewers say the smell is off-putting in some batches. Nutrafol Women is a vitamin that targets hair growth and thickness by targeting the causes of thinning hair -- like your stress levels and nutrition.

It contains medical-grade ingredients, including collagen, maca , astaxanthin and saw palmetto. In addition to vitamins A, C, and D, you get 3, mcg of biotin in this vitamin. Nutrafol says results will be noticeable in three to six months. The thing I like most about Nutrafol is that you don't have just one option; there are several hair supplements to choose from.

You can take Nutrafol's hair wellness quiz to find the best fit for you. For instance, if your hair loss is hormonally related, Nutrafol Women's Balance vitamin is the best choice.

With a four-capsule dosage, that's only a day supply. If you're shopping for an organic hair, skin and nail vitamin supplement, Garden of Life mykind Organic Collagen Builder may be what you're looking for. According to Garden of Life's website, this hair, skin and nail vitamin helps restore and maintain your body's collagen, keratin, and elastin levels.

It's both vegan and organic, and made from whole food ingredients like blended fruit and vegetables. You do get a significant amount of biotin at 2, mcg per serving.

Like Revly, you'll also find green tea extract in this product. Persona Nutrition offers some of the best opportunities to personalize hair, skin and nail vitamins. It's a vitamin subscription service, so you don't have to worry about running out.

They come in convenient daily packs that will be shipped to your home. You start by taking Persona's extensive assessment , which asks about your health concerns, allergies, and diet. This helps match your needs with the supplements offered.

The hair, skin and nail vitamin from Persona aims to smooth fine lines, hydrate your skin and help your hair and nails grow with a balance of ingredients like collagen, hyaluronic acid and horsetail extract. Persona has the one of the highest biotin content on the list at 5 mg or 5, mcg.

With Persona, you can create a regiment of supplements that address the vitamin and minerals you are lacking. They offer a ton of options. After I took the assessment I was matched with over five supplements.

Always check interactions between supplements and your existing medication before starting. More is not always better for you! If you want a one-and-done approach to your vitamin, keep Revly Hair, Skin and Nail Complex in mind. Revly also has an extensive ingredient list which includes a hefty dose of biotin at mcg per serving.

There are also a few ingredients you won't see from other vitamins -- like horsetail, methylsulfonylmethane or MSM and gotu kola , which have been linked to good joint health and anti-aging, respectively. In addition to potentially decreasing blood pressure, gotu kola may also stimulate collagen production.

You'll also find green tea extract in this vitamin. A study has found that green tea extract may treat hair loss.

Note that some people prefer their vitamins without any additives. If you're one of them, this is not the vitamin for you. Revly's hair, skin and nail vitamin doesn't include vitamins outside of biotin and other vitamins.

Always study the ingredients in any vitamin supplement. If you are looking to support healthy hair, skin and skins, look for vitamins that contain biotin, collagen, vitamin C and omega-3s. Speak with your doctor before starting any supplements. You may have to take up to four pills each day, depending on the serving size.

Keep this in mind if you dislike swallowing a lot of pills. Also, the serving size directly affects how long a bottle will last you. Even if you have a product with tablets, if you have to take four tablets a day, this will only last you 30 days. Vitamins and supplements come in either tablet, capsule, gel capsule or gummy foam.

Depending on your personal preference, you should look for vitamins that fit your needs. While dietary supplements aren't regulated by the FDA, there are a few verifications you can check for that ensure the product you're buying is safe to use.

The FDA doesn't regulate vitamins and supplements, which means there are fewer quality regulations for companies to meet. I haven't tested these products in-house; the choices are based on product research for vitamin and mineral ingredients, third-party certifications and consumer reviews.

Several vitamins and nutrients play a part in improving the health and appearance of your hair, skin and nails. Vitamin B7, collagen, vitamin C and omega-3s are all great supplements. Meder Beauty Science Red-Apax Calming Sheet Masks. Latest stories. Skin Science. Joanna Loves.

It protects us from factors that age us from the inside, like poor sleep. It also works topically. Research shows that vitamin C protects against sun damage, age spots, and even melanoma, the deadliest type of skin cancer. As the skin ages, a diet high in vitamin C reduces wrinkles by nudging the body to make more collagen and elastin, two proteins that give the skin structure, stretch, and strength.

It also helps the skin retain moisture, which can reduce the appearance of fine lines. Consuming adequate vitamin C even helps heal scratches and cuts, says Julie Garden-Robinson, PhD, RD, a food-and-nutrition specialist at North Dakota State University.

You can also safely supplement with up to 1, mg a day. Look for those with L-ascorbic acid, an active form of the ­vitamin that your body can put to work immediately. Because vitamin C degrades quickly when exposed to oxygen and light, choose products packaged in dark-tinted bottles with airless dispensers.

This essential nutrient supports nearly every aspect of health. Carotenoids are absorbed through the gut and dispersed throughout the skin. Like all antioxidants, they help reduce the daily damage wreaked by environmental insults and ward off premature aging and skin cancer.

The best-known carotenoid is beta-carotene, some of which is converted to vitamin A in the skin. Found in carrots, pumpkins, sweet potatoes, and mangoes, beta-carotene reduces skin inflammation by inhibiting free radicals caused by UV rays and air pollution, studies show.

You can get your daily dose by eating spinach, kale, basil, parsley, and egg yolks. Astaxanthin is another key carotenoid for skin health. It bestows the reddish-pink hue in salmon and many shellfish, and it protects mitochondria , the engines of our cells.

Aging reduces the number, power, and efficiency of the mitochondria in skin cells; astaxanthin may slow this process, says Tager.

Think pink. As for topical applications of carotenoids, retinoids are a derivative of vitamin A that can produce some powerful effects in maturing skin. Commonly known as retinol, these fat-soluble molecules can penetrate skin and fuel the production of elastin and collagen to increase elasticity.

They also modulate melanin, so retinol may help reduce age spots. Note that retinol can cause dryness, irritation, and sun sensitivity, so proceed with caution. The most abundant protein in the body, collagen is a key component of skin, tendons, and ligaments.

As the body ages, it makes less and lower quality collagen. This contributes to reduced elasticity and less fresh-looking skin. Eating meat twice a week provides all the collagen most people need, says Tager.

Other foods can help stimulate collagen production too. Meanwhile, sales of collagen supplements are booming. Collagen peptides , also known as hydrolyzed collagen, are made from the bones, skin, and connective tissue of cows, pigs, and chickens, as well as from fish scales and skin.

These proteins break down into amino acids in the digestive tract, which are absorbed into the bloodstream and distributed to the skin.

Unlike vitamin C, which dissipates quickly, collagen peptides remain in the skin for up to 14 days. Collagen supports moisture retention by increasing production of hyaluronic acid, which makes skin more pliable.

But she was swayed by a raft of studies showing its benefits. Most notably, in , the International Journal of Dermatology and Venereology published a meta-analysis of 19 double-blind, randomly controlled trials on the effects of collagen supplementation on skin aging, where the majority of subjects showed improved elasticity and fewer wrinkles.

Worth noting: Collagen products that claim to be animal-free are engaging in a sleight of hand. These are believed to help the body make more of its own collagen. If you eat a vegetarian or vegan diet, Garden-Robinson suggests getting two servings of protein a day from a variety of sources, including nuts and beans.

And if you eat animal products and you want an extra dose of collagen, she suggests drinking a cup of bone broth. Popularly known as CoQ10, this micronutrient is vital for mitochondrial function.

In the skin, coenzyme Q10 helps fight free radicals triggered by UV radiation and pollution. Supplements are the easiest way to get a skin-supportive amount of CoQ10, though there are several potent food sources.

Organ meats may have the highest concentration, followed by fatty fish, like salmon and mackerel. Another potent anti-inflammatory, vitamin E works best in the company of vitamin C. This duo protects the skin against its No. Boost your vitamin E with nuts and seeds, avocados, red bell peppers, and dark, leafy greens.

When applied topically, vitamin E supports healing, protects collagen, and smooths rough skin. The skin requires up to mg of fat daily to stay healthy, in part because fat is a key ingredient in the glue that holds skin cells together.

Just as in leaky gut syndrome, loose junctions in the outside skin can lead to transepidermal water loss. This makes the skin drier and less protective, increasing the likelihood of skin damage from friction. Psoriasis, eczema, acne, and dandruff all involve some degree of transepidermal water loss.

An excess of poor-quality hydrogenated oils and certain saturated fats can wreak havoc on your skin. To feed the skin, Tager recom­mends a Mediterranean-style diet that emphasizes beneficial fats, such as olive oil. Fatty fish, raw nuts, avocados, and flax oil are good sources of high-quality fats, as are fish-oil supplements.

Studies also show that fermentation of high-fiber foods generates short-chain fatty acids SCFAs. These include butyrate, propionate, and acetate, all of which help heal the skin from the inside out. Butyrate plays a surprisingly big role in overall health. CoQ10 may benefit skin health from its antioxidant properties and also the role it plays in mitochondrial health.

Because skin cells are constantly being replaced, mitochondria in skin cells play an important role for health. However, as we age and with UV ray exposure, skin CoQ10 levels go down.

Therefore, researchers suggest increasing CoQ10 levels may help skin health as we age. While research suggests CoQ10 has skin health benefits, note more research is needed on the benefits of taking CoQ10 orally and ideal dosage for skin health.

If a CoQ supplement has been cleared for you from a healthcare professional, we suggest the GNC milligram CoQ10 option because GNC had this supplement tested in a review of coQ10 supplements through ConsumerLab.

This verifies that the product contains what it says it contains without potentially harmful contamination. This dosage also allows for some flexibility.

For heart health benefits from CoQ10, one to four tablets after meals is a general serving suggestion. A healthcare professional can recommend the dose to best suit your needs.

Key Specs: Form: softgel Type: CoQ Dose: 1 softgel Third-Party Certified: yes Servings Per Container: Vitamin E is an antioxidant that has important roles in immune health, eye, brain, and skin health. It can play a role in reducing UV damage to the skin and promoting wound healing.

Consuming food sources of vitamin E and A, or taking a healthcare professional-approved supplement might be beneficial for individuals with acne. We can get vitamin E from many foods including nuts, seeds, fortified cereals, and vegetable oils.

Since it is a fat-soluble vitamin, it is best absorbed with dietary fat. Many people consume adequate amounts of vitamin E from food alone, but for some people with GI disorders that inhibit fat absorption a vitamin E supplement may be beneficial.

If a vitamin E supplement has been recommended for you, we like the Kirkland Signature milligram option because it is USP verified and well below the UL for vitamin E of 1, milligrams. We also like that this supplement is budget-friendly.

If you take any medication, be sure to consult a healthcare professional before taking vitamin E. Vitamin E supplement may interfere with anticoagulant, antiplatelet, or simvastatin medications or interfere with chemotherapy or radiation treatments.

Key Specs: Form: softgel Type: vitamin E Dose: 1 softgel Third-Party Certified: yes Servings Per Container: Like vitamin C, zinc is often associated with immunity. However, being deficient in zinc can greatly impact skin health.

Delayed wound healing, acrodermatitis enteropathica, cheilitis , and dermatitis can all be signs of zinc deficiency. Therefore, taking a zinc supplement can be helpful for skin health if you are zinc deficient.

People with inflammatory bowel disease IBD , who had bariatric surgery, vegans, those who are pregnant or lactating are all at a higher risk for not getting enough zinc in the diet. People with IBD are particularly at a higher risk for zinc deficiency.

Good food sources of zinc include oysters, beef, fortified breakfast cereals, and pumpkin seeds. We like that it is a moderate dose, containing percent Daily Value of zinc per serving, but since it is liquid it is easy to adjust the dose to meet your needs.

Key Specs: Form: liquid Type: zinc Dose: 10 drops Third-Party Certified: yes Servings Per Container: Vitamin A is arguably most widely associated with its role in eye health , but it also plays a role in skin and immune health. In fact, many topical skin care products have vitamin A or retinol as an ingredient.

It protects the body from infections by keeping the skin and tissues in the digestive and respiratory tract healthy. Like many other nutrients for skin health, the majority of Americans consume enough vitamin A from food alone.

However, those with gastrointestinal absorption issues or cystic fibrosis are at an increased risk for vitamin A deficiency and may best benefit from a vitamin A supplement.

Foods rich in vitamin A include sweet potatoes, carrots, and spinach. These kinds of plant sources of vitamin A are less bioavailable, but cooking them increases their bioavailability.

Animal sources of vitamin A, like eggs, liver, and fish, have a much higher bioavailability. Most vitamin A supplements on the market come in very high doses. Note the form of vitamin A used is made from fish, and gelatin is used in this supplement. Therefore, it is not a good fit for those with fish allergies or avoiding these animal ingredients.

If you use creams or gels to put on your skin, a healthcare professional can check to see if they have retinoid, retinol, retinyl-palmitate, retinyl-acetate, retinaldehyde ingredients, as these are vitamin A derivatives.

Before adding an oral vitamin A supplement, check with a healthcare professional to see what is the best form of vitamin A supplements—and how much—you may need for your skin health.

Key Specs: Form: softgel Type: vitamin A Dose: 1 softgel Third-Party Certified: yes Servings Per Container: If you're looking for a skin health supplement to target wrinkles and promote healthy skin hydration, we recommend Ritual HyaCera.

Ritual includes a specific low molecular weight hyaluronic acid that has been shown in research studies to provide benefits for fighting wrinkles and improving skin hydration. Hyaluronic acid is usually thought of as a topical skin supplement, but it can also be taken orally. It has been shown to be helpful for preventing and treating wrinkles associated with aging and chronic sun exposure.

Another research-backed ingredient included in this supplement is Ceratiq. Research has shown this wheat oil-derived ingredient when taken as a supplement for 3 months can help improve skin hydration. We appreciate Ritual has strong third-party testing, traceable ingredients, and this supplement dose is just one capsule and comes pleasantly vanilla-scented.

It is vegan, gluten-free, and non-GMO verified. One thing to keep in mind, as with any supplement, is it may take at least three months to notice any skin benefits. It should also be taken consistently for best results.

If you are pregnant, breastfeeding, or take medications, be sure to consult a healthcare professional before taking. Key Specs: Form: capsule Type: hyaluronic acid, ceratiq Dose: 30 capsules Third-Party Certified: yes Servings Per Container: Coffee may not be the first thing to come to your mind as something that can benefit skin health.

However, coffee is a good source of polyphenols antioxidants that can help protect the skin from UV damage and help lower inflammation in the body. In fact, one study found coffee consumption and total antioxidant intake were associated with low facial pigment spots.

Researchers suggest coffee may help protect skin from photoaging and protect skin against pigmentation. Coffee's role in eczema has been debated , but there is no research to suggest coffee can worsen eczema unless you have an allergy or add other ingredients to coffee you have an allergy.

For an added skin health benefit, we like Zend Coffee's functional beauty blend that has added hyaluronic acid, biotin, and vitamin C. You can add this beauty blend to any ground coffee you order as a subscription.

Zend makes it easy to customize no matter your functional blend, flavor, and roast preference. They also have a recovery blend with added turmeric, cinnamon, ginger root, and black pepper and a serenity blend with L-Theanine and Rhodiola rosea. While these blends are third-party tested for ingredient safety, note the exact amounts of ingredients in the functional blends are not listed.

Key Specs: Form: coffee grounds Type: hyaluronic acid, vitamin C Dose: day supply Third-Party Certified: yes Servings Per Container: In general, if you eat a well-rounded diet rich in vegetables, fruits, whole grains, lean meats, fish, and heart-healthy fats you will be able to meet your skin health needs through food alone.

However, if your diet lacks nutritional variety or you have a condition like inflammatory bowel disease that interferes with absorption of certain nutrients, your skin may benefit from taking certain supplements. Individuals that may benefit from supplements for skin health include:. Keep in mind supplements for skin health can vary from a single nutrient to a mix of many different nutrients.

Therefore, there is a wide range of how skin health supplements may or may not benefit your needs. In general, those who may not benefit from vitamins and supplements for skin health include:.

Our team works hard to be transparent about why we recommend certain supplements; you can read more about our dietary supplement methodology here.

We support supplements that are evidence-based and rooted in science. We value certain product attributes that we find to be associated with the highest quality products.

We prioritize products that are third-party tested and certified by one of three independent, third party certifiers: USP, NSF, or ConsumerLab.

It's important to note that the FDA does not review dietary supplements for safety and effectiveness before they go to market. Our team of experts has created a detailed, science-backed methodology to choose the supplements we recommend. To help in the process, we also spoke with several experts in the field.

Those experts included:. Supplements that are third-party tested are sent to a lab where they are tested to ensure they contain what they say they contain and are not contaminated with specific high-risk, common contaminants. The various supplements included in this roundup come in different forms—pills, powder, liquid, and gummies.

Pills can be convenient and easier to find, while liquid or powder can offer more flexibility in dosage. Since single-nutrient supplements can be hard to find in smaller doses, the flexible dose of a liquid supplement can be useful if you are not severely deficient in the nutrient.

Collagen is most commonly available as a powder for supplements for skin health. You can find some of the vitamins and supplements for skin health in varying combinations.

They might also have other ingredients like hyaluronic acid or biotin. Both of these do play a role in skin health, but biotin deficiency is uncommon in the U.

so supplementation is often unnecessary. It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included, relative to the recommended daily value of that ingredient.

Please bring the supplement label to a healthcare provider to review the different ingredients contained in the supplement and any potential interactions between these ingredients and other supplements and medications you are taking. Popularity of hair, skin, and nail supplements has grown in recent years.

One of the main ingredients in these is biotin ; however, research does not support taking a biotin supplement unless deficient, which is rare amongst Americans. While there is no known UL for biotin, you may want to be weary of skin health supplements with really high biotin doses—at the very least to save you from unnecessary spending.

Sometimes there may be herbal additives in skin health supplements that lack research on safety and efficacy. Always check with your healthcare provider before starting a new supplement even if it just is an herbal blend.

Supplements high in vitamin B6, B12, or kelp supplements which are high in iodine may increase risk of acne for some people, Therefore, if you are prone to acne, avoiding these supplements in addition to whey protein or steriod-like supplements may be recommended.

If you struggle with acne, be sure to tell a healthcare provider all the supplements and medications you take so they are aware of any potential interactions.

Below are the recommended dietary allowances RDAs or daily adequate intakes AIs for adults for the vitamins and supplements beneficial for skin health. Some recommended doses vary based on sex or age, while CoQ10, omega 3, and collagen do not have an RDA or AI.

Men : 90 milligrams add 35 milligrams if you smoke. Women : 75 milligrams add 35 milligrams if you smoke. Men : micrograms 3, IU. Women : micrograms 2, IU. Ages 15 micrograms IU. Men : 1. Women : 1.

Men : 11 milligrams. Women : 8 milligrams. Each vitamin and mineral has a different tolerable upper intake level UL. Unless advised from a healthcare professional to treat a nutrient deficiency, if you exceed this daily dose you are at increased risk for adverse effects or toxicity.

CoQ10 and collagen have no officially established UL. Research suggests that collage supplementation is promising for various facets of skin health including wound healing, aging, skin elasticity , and hydration. The researchers also noted that collagen supplementation seems to be quite safe, with no adverse events reported.

However, Yelena Wheeler, MPH, RDN, notes that collagen supplements may not be necessary for skin health depending on your diet. However, maintaining a healthy well balanced diet full of antioxidants, consuming enough liquids for adequate hydration, minimizing dehydrating foods such as alcohol and caffeine, and wearing sun protection will also result in a more hydrated skin appearance.

It really comes down to lifestyle factors and balancing blood sugar through a whole food diet of protein, healthy fats, and fiber. For healthy skin care, the American Academy of Dermatology AAD recommends wearing sunscreen daily, avoiding tanning beds, using skin care products created for your skin type, keeping your hands off of your face, and treating your lips to prevent skin cancer.

The AAD also recommends cleansing your face twice a day, getting adequate sleep, quitting smoking, and eating a well-balanced diet. As you can see, skin health is more than taking a supplement, and caring for many different areas of your health can have positive effects on your skin.

While fine lines and wrinkles are a normal part of aging, some supplements may counter these effects. Since vitamin C is needed for collagen production, ensuring you get adequate vitamin C is also important. CoQ may also prevent fine lines and wrinkles, but more research is needed.

One small study found that 50 to grams of CoQ for 12 weeks significantly reduced wrinkles and improved skin smoothness. Our gut health can impact many areas of health including skin health. The gut helps produce and regulate certain hormones.

One of these is estrogen. Isabel Vasquez RD, LDN is a bilingual registered dietitian whose clinical experience includes providing outpatient nutrition counseling to adults with a variety of chronic health conditions along with providing family-based treatment for eating disorders in children and adolescents.
