No Lie: These Vitamins Will Make Your Hair, Skin, and Nails Flawless

THE/THIRTY readers love this product. It's a best seller on our site. Labeled as Amazon's Choice, Sports Research Biotin supplement is formulated with coconut oil and has over 10,000 customer reviews and 4.5 stars.

Personally, I've been taking these gummies (when I remember to) for the past three weeks. I haven't seen any changes yet, but Who What Wear's beauty editor, Erin Jahns, swears by them and says I should stick with it. The vegan supplement also promotes hair pigmentation, too.

Another recommendation from Jahns, this physician-formulated supplement can help increase and improve hair growth. Some ingredients include ashwagandha root, curcumin, saw palmetto, marine collagen, and biotin.

SuperHair is non-GMO, vegan, gluten-free, and contains no soy, dairy, corn, or sugar, so it works with many different diets. It contains ingredients like biotin, kelp, saw palmetto, horsetail, ashwagandha, and ginseng. One reviewer wrote, "It has taken 30 days, but well worth the wait, as I am beginning to see hair growth and much more volume on my crown. I am thrilled beyond words, as this is the first all natural product that has actually worked."

Another biotin pick, this one is easy to ingest in gummy form. It has a blueberry flavor and is free of gluten and high-fructose corn syrup.

These gummies are another staff favorite (and an Amazon's Choice pick, too). They contain vitamin C and E, biotin, and folic acid. Reviewers say their hair has grown longer and stronger, and they report the supplements taste good as well.

These collagen gummies can help improve the appearance of hair, skin, and nails. Ingredients include vitamin C and E, biotin, and hydrolyzed collagen. One reviewer wrote, "Got these to see if it would help hair growth after having a surgery that messed with my hormones and caused hair to fall out. Seems to have helped since I've been taking it almost two weeks and I have baby hairs popping up! My nails seem a little stronger too since they aren't breaking as easily."

Part of Amazon's in-house brand, this vegan and gluten-free formula contains biotin, carrot, and dandelion root, among other botanical ingredients. Each bottle has a 90-day supply.

Bamboo extract is rich in silica, which helps to promote the formation of collagen. This is essential for achieving healthy hair and nails, as well as smooth, hydrated skin. Several five-star reviews attest to the power of this vitamin in promoting both hair and nail growth for men and women. 

Almost everyone in our office is a big fan of Vital Proteins products. The Beauty Collagen can help you achieve radiant skin—just add to your water, smoothies, or teas. Ingredients include marine-based collagen peptides, hyaluronic acid, probiotics, vitamin C, and biotin.

This supplement is formulated with zinc and selenium, which can protect from oxidative stress, plus anti-aging compounds purslane, astaxanthin, coenzyme Q10, glutathione, and bamboo extract.

Beauty Dust contains adaptogens (amla, ashwagandha, rehmannia, goji, and pearl) that are said to have anti-aging properties and can help clear your skin. Add one teaspoon of the supplement to your water, tea, or juice. Its flavor is described as "tart and berry."

The program of supplements is supposed to "nourish and condition skin," but be warned, this one takes a bit more commitment than popping a gummy once a day. It's recommended that you take one packet twice daily with meals—and one packet contains three soft gels, two capsules, and three caplets.

Olly gummies contain vitamin E and A, zinc, and botanicals to promote a clear complexion and skin generation. One reviewer wrote of the pros and cons: "I've been using these for a couple of weeks now and I have already noticed a big difference. My pores are smaller, I have fewer breakouts, and my skin just looks healthier. The only negative is that they smell kind of bad, but the taste is really good."

These plant-derived supplements are said to hydrate the skin, minimizing dryness, redness, and itching. One reviewer wrote, "While this product is not a facelift in a bottle, nor did it diminish any of my facial lines or wrinkles, I firmly believe that it does provide skin hydration from the inside out. I tend to suffer from intermittent itching during the winter months that no moisturizer has ever helped, and this is the first winter that I did not experience any itching."

These conveniently packaged daily doses of essential vitamins and nutrients, including antioxidants, green tea, biotin, and vitamins A, C, E, and K. One review says, "I've been taking this on-and-off for a few years now, and I've noticed when I take them they make a huge difference in my skin's radiance, smoothness, and clarity." It continues, "I have acne-prone skin and these supplements help my blemishes and post-acne marks heal and fade much more quickly." 

Featuring a blend of krill oil, hyaluronic acid, red clover, and cocoa, this beauty supplement boosts the body's ability to retain moisture, absorb nutrients, and strengthen skin from within. A five-star review proclaimed, "I have been using this for a year, and it has worked wonders on my skin!"

These plant-based biotin capsules can help improve the strength of your nails and hair. A five-star review stated, "I just bought my third bottle; I am in love! My hair grows so fast, and my nails, which are usually pathetic and weak, can last weeks without breaking or peeling. I've seen the same dosage of biotin sold for higher and some [for] lower, but honestly, this works—and it's a nice middle-ground for the price."

This all-around beauty gummy contains biotin, keratin, and vitamins C and E, which work together to support and nourish hair, skin, and nails. One five-star reviewer shares, "After years of fighting cancer... I finally have long, strong nails, plus my hair is growing again!"

"My nails have broken far less frequently and have remained flexible, yet stronger," writes one five-star reviewer. "I'm just about done with my first bottle and have already ordered a second," they continue. These 100% vegetarian and easy-to-swallow soft capsules are also gluten-, wheat-, and dairy-free, making it a great option for those seeking the purest, most potent form of biotin available.
