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.
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.
Still, despite the lack of strong evidence, biotin is commonly found in hair, skin, and nail supplements — and often in high doses. Fortunately, even large doses of biotin have not been shown to be toxic (
Vitamins A, D, and E
Vitamins A, D, and E are fat-soluble vitamins that are frequently found in hair, skin, and nail 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 (
While more research is needed, vitamin A may also be helpful for people experiencing acne.
One study of 50 adults found that taking 20 mg of isotretinoin — a derivative of vitamin A that’s also known as Accutane — daily for 3 months was effective in treating moderate to severe acne (
As for vitamin D, research suggests there’s a potential link between acne and low levels of vitamin D.
Finally, vitamin E is known to have potent antioxidant effects, which research suggests may have benefits for your hair and skin.
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).
- Vitamin A: 10,000 IU (3,000 mcg)
- Vitamin D: 4,000 IU (100 mcg)
- Vitamin E: 1,100 IU (1,000 mg)
Methylsulfonylmethane, or 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% (
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 (
Hyaluronic acid is a naturally occurring substance that helps maintain hydration levels in the 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 individuals with dry skin (
Similarly, topical use may also be helpful for nail health. However, research on the efficacy of oral hyaluronic acid for nails is lacking (
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 — a protein that is the primary structural component of your hair, skin, and nails. Collagen also works with elastin to help keep your skin looking healthy and tight (
A small 2014 study found that taking 2.5–5 grams of collagen daily for 8 weeks significantly improved skin elasticity in women ages 35–55 (
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 confirming its effectiveness in fighting hair damage is limited (
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 showed a notable decrease in the frequency of nail breaks (
Horsetail is a fern that contains silica, a powerful antioxidant that helps protect against cellular damage caused by free radicals.
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 (
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 (
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 (
Additionally, horsetail supplements may interact with some medications, so be sure to talk with a healthcare professional before adding this supplement to your routine (
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. Another potential acne fighter, vitamin D, is included in this product as well (
The product also contains vitamin B12, which may be helpful for skin health.
However, while vitamin B12 deficiency is linked with various conditions, such as nail discoloration and changes in skin pigmentation, it’s unclear whether taking a vitamin B12 supplement is beneficial if your vitamin B12 levels are adequate (
Other notable ingredients in Nature’s Bounty Extra Strength Hair, Skin, and Nails include:
- Para-aminobenzoic acid (PABA). Also known as vitamin B10, PABA helps absorb UVB rays associated with sunburns and DNA damage, so it’s potentially protective for your skin. PABA may also be effective in re-pigmentation of graying hair, but research is limited (
40, 41, 42).
- 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 (
29, 30, 31, 32, 33).
- Hyaluronic acid. This ingredient may help boost moisture in dry skin (
- Collagen. This protein is important for improving skin elasticity and supporting nail health (
23, 25, 28).
- Zinc. This mineral supports collagen production in the body. Supplementing zinc may also help treat acne, especially if you don’t get enough zinc from your diet (
43, 44, 45).
- Alpha lipoic acid. This naturally occurring compound may help fight the signs of aging in your skin (
- Argan oil. While more research is needed, argan oil may help improve skin elasticity (

Revly’s supplement also contains several ingredients that aren’t as common, 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 (
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 (

What’s more, B. Well is highly rated, with several customers noting that their hair feels stronger and looks shiner since they began taking the supplement.
One important note is that while the company claims to use high quality ingredients, Briogeo’s B. Well vitamins are not third-party certified.

While Persona’s proprietary blends list ingredients, they don’t disclose the exact amount of each ingredient. As a result, if you’re sensitive to any of the ingredients listed, it’s best to avoid this supplement.
