Although a balanced diet is key to keeping them healthy, you may also want to consider taking dietary supplements -- after consulting your doctor about the essential vitamins you might need for better hair growth, glowing skin and healthy nails.You may think your diet covers everything your body needs, but doctors often prescribe vitamins and supplements to help people who are deficient in ways they can't help.

So finding the right vitamins can be daunting. Vitamins might be weighed in milligrams or micrograms, and there's a considerable difference: a milligram is equivalent to 1,000 micrograms, in the same way that a gram is equivalent to 1,000 milligrams.Our CNET experts have gone through scientific research to find the best vitamin supplements for hair, skin and nails, to help you match your goals and save you trouble when you aren't sure where to look.What are the best overall vitamins for hair, skin and nails?There are a lot of multivitamins that claim that they can improve hair, skin and nails, you need to pay attention to the ingredients. The best overall vitamins for hair, skin and nails include vitamin B7 (biotin), collagen, vitamin C and omega-3s.Vitamin B7 is essential for the health of your hair, skin and nails. It isn't the type of thing you can stock up on -- taking a ton of biotin doesn't amplify the benefits. Collagen is a protein that makes up connective tissue. As we age and our production of collagen decreases, the once-tight fibers become more like a maze. This translates to wrinkles on the face. Supplements include collagen to help your skin elasticity and reduce wrinkles. Vitamin C has various benefits for the body, and it also increases collagen production in your body. Lastly, Omega-3s help maintain the cholesterol-derived layer of our skin cells. They contribute to the shine of your hair and keep your scalp healthy. Studies have found that it can also help treat the symptoms of inflammatory skin conditions.Best vitamins for hair, skin and nails in 2024 Pros Affordable multivitamin at only $12 a bottle USP certified, meaning the factories meet FDA good manufacturing practices Lasts for 50 days Cons The vitamins aren't third-party certified for purity Not an option for vegans because they contain gelatin Price $ Form Gel capsuleServing size Three gel capsulesSupply 50 days $12 at Amazon 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. Photo Gallery 1/1 $13 at Amazon Best gummy vitamin for hair, skin and nails Olly Undeniable Beauty Hair, Skin and Nails $13 at Amazon $14 at Olly 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-puttingin 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. Photo Gallery 1/1
