This article provides a list of the 7 best vitamins for hair, skin, and nails, as well as tips on what to look for when selecting a supplement.

Shopping for a hair, nails, and skin supplement can be overwhelming. Here are a few key factors to consider.

Ingredient quality and effectiveness

Ideally, look for products that contain research-backed ingredients and are free of artificial additives and fillers.

If you’re interested in a supplement that contains a proprietary blend, keep in mind that manufacturers do not disclose the exact amounts of the ingredients used in the blends. Therefore, you’ll want to avoid any products that contain ingredients you may be sensitive to.

Additionally, keep in mind that while studies do support the effectiveness of some ingredients, research on the benefits of these vitamins is still quite limited.

Therefore, there’s no guarantee these products will result in notable differences in your hair, skin, or nails.

Brand reputation and third-party testing

Any time you purchase supplements, it’s important to buy from a trusted source.

For an extra level of reassurance, look for vitamins that are tested by a third-party organization such as USP, NSF, or ConsumerLab.

A third-party seal of approval guarantees that the product contains the types and amounts of ingredients that are listed on the bottle.

Potential contraindications

Because some ingredients may interact with medications or be unsafe if you’re pregnant or breastfeeding, it’s best to talk with a healthcare professional before trying any new supplements.

Best overall

Nature’s Bounty Extra Strength Hair, Skin, and Nails

  • Price: $$
  • Type: softgel capsule
  • Age range: 18+
  • Dosage: 3 softgels per serving
  • Certified: non-GMO verified and free of dairy, gluten, lactose, fish, sugar, and artificial flavors

Nature’s Bounty Extra Strength Hair, Skin, and Nails is a great option if you’re looking for a multivitamin that’s also formulated to support healthy hair, skin, and nails.

Among the many vitamins incorporated in this supplement is vitamin A, which can aid in collagen production and may help improve acne symptoms. This product also contains another potential acne fighter, vitamin D (1, 2, 3, 4).

Other notable ingredients in Nature’s Bounty Extra Strength Hair, Skin, and Nails include:

  • Vitamin B12. For those with a deficiency, vitamin B12 may help with nail discoloration and skin pigmentation changes. Too much vitamin B12 can negatively affect hair, skin, and nails, so take note of any extra sources of B12, although toxicity is unlikely (5, 6, 7).
  • Para-aminobenzoic acid (PABA). Also known as vitamin B10, PABA helps absorb UVB rays associated with sunburn and DNA damage, so it may help protect your skin. PABA may also help with re-pigmentation of graying hair, but research is limited (8, 9, 10).
  • Horsetail. Horsetail may help protect hair from damage-causing oxidative stress and reduce hair shedding and thinning. However, it can interact with some medications, so be sure to check with your doctor first (11, 12, 13, 14, 15).
  • Hyaluronic acid. This ingredient may help boost moisture in dry skin (16, 17).
  • Collagen. This protein is important for improving skin elasticity and supporting nail health (18, 19, 20).
  • Zinc. This mineral supports collagen production in your body. Supplementing zinc may also help treat acne, especially if you don’t get enough zinc from your diet (21, 22, 23).
  • Alpha lipoic acid. This naturally occurring compound may help fight the signs of aging in your skin (24).
  • Argan oil. While more research is needed, argan oil may help improve skin elasticity (25).

Best affordable

Revly Vegan Hair, Skin, & Nails Complex

  • Price: $
  • Type: capsules

Revly’s supplement contains some less common ingredients, such as gotu kola.

An herb used in Ayurvedic medicine, gotu kola has been shown to have potent antioxidant properties. It’s also used topically to help reduce the appearance of stretch marks, though more research is needed on the benefits of taking it orally (28, 29).

The supplement also contains green tea extract, which has been shown to be effective against hair loss and skin aging thanks to its antioxidant activity. Plus, it may help reduce redness caused by acne and keep your skin moisturized (30, 31, 32).

Olly Undeniable Beauty Hair, Skin, and Nails

  • Price: $$
  • Type: gummies
  • Age range: 18+

Best vegan

Briogeo B. Well

  • Price: $$$
  • Type: softgels
  • Age range: 18+
  • Dosage: 2 softgels per day
  • Certified: vegan, gluten-free, cruelty-free

The B. Well supplement from Briogeo is one of the best if you’re looking for a vegan option, as it’s also cruelty-free, meaning the product wasn’t tested on animals.

This supplement contains a type of omega-3 called docosahexaenoic acid (DHA), which may be effective in promoting hair growth, improving hair density, and reducing hair loss (37, 38).

As a result of their potent antioxidant properties, omega-3s may also help reduce inflammation caused by acne, though more research is needed (37, 38, 39, 40, 41).

Additionally, a small 2011 study found that adults who consumed omega-3s through flaxseed oil supplements had noticeably smoother and more hydrated skin after 12 weeks (42).

Other notable ingredients in this supplement are sodium hyaluronate, silica, zinc, vitamin C, and copper (12, 17, 22, 33, 43).

Best for postpartum

Ritual Postnatal Multivitamin

  • Price: $$$
  • Type: capsules
  • Age range: 18+
  • Dosage: 2 capsules per day
  • Certified: non-GMO, vegan, and free of gluten, major allergens, fillers, and preservatives

People who have recently given birth need plenty of nutrients to support their recovery, as well as to produce breast milk for their little one if they choose to breastfeed.

Plus, thanks to changes in hormones, people often notice extra hair shedding during their first year postpartum (44).

In addition to helping you meet your postnatal nutritional needs, Ritual’s supplement contains ingredients that are beneficial for your hair, skin, and nails, including zinc and vitamins A, B12, C, and D (1, 3, 5, 22, 33, 45).

Furthermore, omega-3 supplements may help with perinatal depression and support infants’ brain development (46, 47, 48, 49).

Just remember that it’s important to talk with a healthcare professional before adding any new supplements to your routine, especially if you’re breastfeeding.

The supplement also includes horsetail extract, which may help reduce hair shedding, and L-theanine, an amino acid that may help with sleep (13, 50).

As a complement to the Beauty Sleep supplement, Persona offers a Beauty Wake supplement, which contains all the same ingredients, but with caffeine instead of L-theanine.

Persona also offers a specific hair, skin, and nails vitamin that contains biotin, pantothenic acid (vitamin B5), zinc, copper, and a proprietary blend of collagen, sodium hyaluronate, and flaxseed.

Best organic

mykind Organics Organic Plant Collagen Builder

  • Price: $$$
  • Type: tablets
  • Age range: 18+
  • Dosage: 2 tablets per day
  • Certified: organic, vegan, non-GMO verified, and free of gluten, soy, and artificial fillers and preservatives

If you prefer a supplement that includes whole food ingredients and is made entirely from blended fruits, vegetables, and herbs, then you may want to consider Garden of Life mykind Organics Plant Collagen Builder.

Notable ingredients in this supplement include zinc and vitamins A and C, all of which may help promote healthy hair and skin (22, 33, 45, 51).

It also contains green tea extract, which has been shown to have a moisturizing effect on the skin and may help reduce redness from acne (30, 31, 32).

Here are ingredients that are commonly found in hair, skin, and nails supplements and a brief overview of their effectiveness.


One of the most popular ingredients found in hair, skin, and nails vitamins is biotin, a B vitamin that’s thought to help with hair and nail growth.

While evidence supports its use in individuals who have a biotin deficiency, research on its effectiveness for hair and nails in the general population is mixed (52, 53, 54).

Still, despite the lack of strong evidence, biotin is commonly found in hair, skin, and nails supplements — and often in high doses. Fortunately, even large doses of biotin have not been shown to be toxic (55, 56).

Vitamins A, D, and E

Vitamins A, D, and E are fat-soluble vitamins frequently found in hair, skin, and nails supplements due to their potential benefits, particularly for hair and skin.

For example, adequate intake of vitamin A helps keep your hair and skin moisturized because it boosts the production of collagen, a protein that works with elastin (another protein) to support healthy-looking hair and skin (1, 45, 51).

Additionally, vitamin A deficiency is correlated with both hair and skin conditions, including dry skin and sparse hair It may also be helpful for people experiencing acne (1, 2, 45).

Research also suggests a potential link between acne and low levels of vitamin D, while vitamin E’s antioxidant effects may help protect against hair and skin damage (3, 4, 34, 35)

While research is limited, studies suggest that vitamin E may also protect against UV exposure and help treat atopic dermatitis, an itchy skin condition also known as eczema (35, 36).

It’s important to note that because A, D, and E are fat-soluble vitamins, excess amounts are stored rather than excreted. As a result, these vitamins can be toxic if taken in large quantities.

Unless under the supervision of a healthcare professional, avoid consuming these vitamins in doses above the tolerable upper limit (UL).

The ULs for vitamins A, D, and E are as follows (57, 58, 59):

  • Vitamin A: 10,000 IU (3,000 mcg)
  • Vitamin D: 4,000 IU (100 mcg)
  • Vitamin E: 1,100 IU (1,000 mg)

Methlysulfonylmethane (MSM)

MSM is another common ingredient as a result of limited research on its benefits for skin health.

A small 2019 study with 50 female participants found that taking 400 mg of MSM, in combination with 200 mg of hyaluronic acid and 500 mg of L-carnosine, daily for 2 months significantly improved skin hydration by 15.2% and skin elasticity by 22.6% (26).

Additionally, a small 2020 study found that even a low dose of MSM improved skin elasticity and hydration. It was also effective in reducing visual signs of aging such as skin roughness and facial wrinkles (27).

Hyaluronic acid

Hyaluronic acid is a naturally occurring substance that helps maintain hydration levels in your body.

While it’s commonly found in topical skin care products, oral intake of hyaluronic acid in doses of 120–240 mg per day has been shown to help improve skin moisture, especially in people with dry skin (16, 17).

Similarly, topical use may be helpful for nail health. However, research on the effectiveness of oral hyaluronic acid for nails is lacking (60).


Collagen is the most abundant protein in the body.

It’s also one of the most popular supplements thanks to its role in the production of keratin. Collagen also works with elastin to help keep your skin looking healthy and tight (1).

Studies have shown that taking collagen supplements may help reduce the signs of aging and improve skin hydration and elasticity (18, 19, 61)

However, the supplements used in these studies also included other ingredients. More research is needed on the effectiveness of collagen supplementation on its own.

As for hair health, collagen’s antioxidant properties are thought to be protective against free radicals that can damage hair, though research supporting its effectiveness in fighting hair damage is limited (34, 62, 63).

Finally, collagen may also be helpful for your nails. A small 2017 study found that taking 2.5 grams of collagen daily for 24 weeks improved brittle nails, increased nail growth, and contributed to a notable decrease in the frequency of nail breaks (20).

Horsetail (silica)

Horsetail is a fern that contains silica, a powerful antioxidant that helps protect against cellular damage caused by free radicals.

As a result, horsetail’s antioxidant properties may help prevent hair damage caused by free radicals, though this effect hasn’t been confirmed in humans (11, 34).

Additional research suggests that horsetail may help reduce hair shedding and increase hair density when combined with other effective ingredients, such as biotin and vitamins A and D (12, 13, 14, 15).

However, more research is needed on the effectiveness of horsetail on its own.

Finally, while topical use of horsetail has been shown to help treat nail psoriasis — a chronic condition that can cause brittle and discolored nails — oral intake of horsetail for nail health has not been assessed (64).

As for safety, there’s currently no established toxic level of horsetail. However, diuretic effects have been observed with doses of 900 mg per day (65).

Additionally, horsetail supplements may interact with some medications, so be sure to talk with a healthcare professional before adding this supplement to your routine (66).

While not all supplements are created equal, some contain ingredients that may be beneficial for your hair, skin, and nails.

With so many options to choose from, it’s important to do your research ahead of time to know which product is the best fit for you.

Especially if you’re taking other supplements or prescription medications or are pregnant or breastfeeding, be sure to talk with a healthcare professional before trying any new supplements.

Lastly, remember that supplements are not meant to replace other healthy lifestyle habits, such as maintaining a balanced diet, staying hydrated, managing stress levels, and getting plenty of sleep, all of which also contribute to healthier hair, skin, and nails.
