If you are currently dealing with brittle hair and nails or acne-prone skin, vitamin supplements might be for you. Hair, skin and nails vitamins contain nutrients that can supplement or prevent vitamin deficiencies that may be affecting your health. There are plenty of vitamin supplements on the market, but some won’t be the best for you. Our experts have cured this list by scouring the internet, studying the market, reading hundreds of customer reviews and understanding which vitamins are best for your hair, skin and nails. Here is what they found.

Before we dive into the good stuff, I want to make a quick note on units of measurement. Unfortunately, things aren’t standardized. Depending on the company, the label may have nutrients listed in milligrams or micrograms, which can be confusing. One milligram is equal to 1,000 micrograms. So it’s common to see content for biotin in the thousands when listed in mcg. 

Best overall vitamins for hair, skin and nails

There are a lot of multivitamins that claim that they can improve hair, skin and nails, however, 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. But 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 2023

<div content="LIST ITEM" superlative="Best overall vitamin for hair, skin and nails" description="

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 $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. You also get 100% of your daily recommended amount of vitamin D, which may help clear up acne. Unlike other options available, Nature’s Bounty multivitamin includes horsetail for thinning hair and skin health. That said, 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. However, 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.
