If you’re looking for healthier hair, stronger nails, or clearer skin, you may be wondering whether it’s worth buying a hair, skin, and nails vitamin. Depending on its ingredients, taking one of these supplements may help strengthen your hair and nails or improve skin concerns such as acne. 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. How to choose hair, nails, and skin supplements 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, while studies do support the effectiveness of some ingredients, research on the benefits of hair, skin, and nails supplements 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 Some ingredients may interact with medications or be unsafe if you’re pregnant or breastfeeding. Always talk with a healthcare professional before trying any new supplements to make sure that a product is safe for you to take.

Common ingredients found in hair skin and nails vitamins Here are ingredients that are commonly found in hair, skin, and nails supplements and a brief overview of their effectiveness. Biotin 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 ( 37 , 38 , 39 ). Still, despite the lack of strong evidence, biotin is commonly found in hair, skin, and nails supplements — and often in high doses ( 40 ). While large doses of biotin have not been shown to be toxic, they can affect lab results, which could result in a misdiagnosis of a health condition or inappropriate management of an existing condition ( 41 ). 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 ( 42 ). 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 ( 43 , 44 , 45 ): Vitamin A: 10,000 IU (3,000 mcg)

10,000 IU (3,000 mcg) Vitamin D: 4,000 IU (100 mcg)

4,000 IU (100 mcg) Vitamin E: 1,100 IU (1,000 mg) Keep in mind that if you’re deficient in vitamin D, a healthcare professional might recommend a supplement containing more than 4,000 IU to increase your blood levels sufficiently. Methlysulfonylmethane (MSM) MSM is another common ingredient because studies suggest it has potential 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 improved skin hydration by 15.2% and skin elasticity by 22.6% ( 17 ). 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 ( 18 ). While these results sound promising, overall research on the effectiveness of MSM in hair, skin, and nails vitamins is limited. 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 mg per day has been shown to help improve skin moisture, especially in people with dry skin ( 11 , 12 ). Collagen Collagen is the most abundant protein in your body. Studies have shown that taking collagen supplements may help reduce the signs of aging and improve skin hydration and elasticity ( 6 ). It may also be beneficial in improving brittle nails and preventing hair damage, though more research is needed ( 7 , 46 ). 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 may be beneficial in reducing hair shedding and thinning, but more research is needed ( 10 ). Additionally, horsetail supplements may interact with some medications, so be sure to talk with a healthcare professional before adding this supplement to your routine ( 47 ). Frequently asked questions Is it safe to take hair, skin, and nail vitamins daily? Dietary supplements such as hair, skin, and nail vitamins are not regulated by the Food and Drug Administration (FDA) the same way that medications are. Specifically, the FDA doesn’t test to ensure that a supplement contains the types and amounts of ingredients that its label claims it does, which is why it’s best to choose supplements that are third-party tested for purity and potency ( 48 ). Also keep in mind that these supplements may not be safe for all people ( 49 ). For example, because many of these supplements contain high doses of some nutrients, toxicity is possible, especially if you’re already taking another supplement, such as a multivitamin. Additionally, some ingredients found in hair, skin, and nail vitamins may interact with certain medications or are contraindicated during pregnancy and lactation ( 49 ). It’s important to review any new supplement with a healthcare professional before taking it. Do hair, skin, and nail vitamins work? Some ingredients commonly found in hair, skin, and nail vitamins, like collagen and hyaluronic acid, have more research to support their effectiveness than others ( 6 , 11 , 12 ). Still, it’s important to keep in mind that the overall research on these supplements is limited. As a result, more robust studies are needed before we can confidently say whether hair, nail, and skin vitamins are effective. Do hair, skin, and nail vitamins help with hair growth? There’s some research to support the use of certain ingredients for hair growth and health, such as horsetail and DHA omega-3s. However, there’s currently insufficient evidence to confirm these benefits ( 10 , 27 , 28 ). How long does it take hair, skin, and nail vitamins to work? While the science on hair, skin, and nails vitamins is still inconclusive, studies that found positive effects of individual ingredients commonly found in these products ranged from in length from 40 days to 6 months ( 6 , 10 , 11 , 27 ).
