Best Vitamins for Healthy Hair, Skin and Nails in 2025

Nature's Bounty Extra Strength multivitamin is the best overall hair, skin and nail vitamin because of its robust nutrient composition. It's also one of the most affordable multivitamins you can find, at around $10 for a 150-capsule bottle. The dosage is three soft gel capsules each day -- not the worst I've seen, but not the best either. 

Vitamin A and zinc are included in this multivitamin to promote collagen production. If you have a vitamin D deficiency, a huge benefit of this is you also get 100% of your daily recommended amount, which may help clear up acne. Unlike other options available, Nature's Bounty multivitamin includes horsetail for thinning hair and skin health. A 2019 review of research found insufficient evidence to establish horsetail as an effective treatment for hair loss. 

Nature's Bounty also includes a significant amount of biotin (vitamin B7) at 5,000 mcg per serving. That sounds like a lot, but no side effects have been reported in doses of up to 10,000 mcg (10 mg) of biotin. Experts note that supplementing biotin at high levels can cause false or low test results for immunoassays, which use biotin as part of the testing method. That's something to consider for upcoming doctor's appointments.

Olly Undeniable Beauty gummy vitamins promote hair, skin and nail health with key ingredients biotin, vitamin C, vitamin E and keratin. Vitamin E has been linked to treating eczema by suppressing inflammation. 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 2,500 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. The research into the effectiveness of taking additional keratin supplements is lacking, but 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. Note that some reviewers say the smell is off-putting in some batches. 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.

Nutrafol Women vitamins support hair growth by focusing on the causes of thinning hair -- like your stress levels and nutrition. They contain medical-grade ingredients, including collagen, maca, astaxanthin and saw palmetto. In addition to vitamin A, vitamin C and vitamin D, you get 3,000 mcg of biotin in this vitamin. Nutrafol has been clinically studied and shown to promote hair regrowth by 80% over time. 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.

Nutrafol hair supplements have the highest vitamin levels on the list, which means they're more expensive for a 120-capsule bottle. With a four-capsule dosage, that's only a 30-day supply. You can opt for monthly delivery subscription through Amazon and knock that price down to $79 per month.

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 one of the highest biotin content on the list at 5 mg or 5,000 mcg. 

With Persona, you can create a regiment of supplements that address the vitamins 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. Amazon's answer to other vitamins on the market, Revly only costs $15 for a 90-day supply, making it the most affordable hair, skin and nail vitamin on the list.

Revly also has an extensive ingredient list which includes a hefty dose of biotin at 2000 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.
