Anyone hunting for an all-star biotin supplement with thousands of positive reviews should go for Sports Research’s Biotin with Organic Coconut Oil supplement. It contains 10,000 mcg of biotin in cold-pressed organic coconut oil. (Coconut oil may help some people shed a few pounds, improve your body’s immune response, and potentially help control diabetes symptoms.) An added bonus: this supplement is GMO-free.

Best Budget: Nature’s Bounty Biotin

Reaping the benefits of biotin doesn’t have to cost a fortune. Nature’s Bounty has a highly effective option for a fraction of the cost of competitors. Their rapid release softgels are made without preservatives, gluten, or sugar, and they contain just as many micrograms of biotin as pricier brands.

Price-conscious reviewers loved this supplement’s smaller size, noting that it was easier to swallow than other pills with the same level of biotin. They also noticed substantial differences in the strength and health of their hair and nails in just a few months.

Best Vegan: PURE RESEARCH Extra Strength Biotin Liquid Drops

If you follow a vegan lifestyle, you’re probably used to double-checking labels and carefully vetting any health products to make sure they match your vegan requirements. A lot of people don’t think about vegan needs when it comes to supplements, but capsule supplements are often made from animal-based gelatin. PURE RESEARCH’s Extra Strength Biotin Liquid Drops take capsules out of the equation for a powerful supplement that checks all the must-have boxes for vegans.

This extra-strength liquid supplement absorbs more quickly than other options since there’s no capsule for your body to break down before the active ingredient is released. There are more than 60 servings in this delicious berry-flavored liquid, and it’s completely free of animal products or byproducts.

Best for Hair Growth: Zhou Nutrition HAIRFLUENCE

One of the biggest reasons people start taking biotin supplements is to promote hair growth, whether they’re looking for faster regrowth after a short haircut or just want thicker, lusher locks. Zhou Nutrition’s HAIRFLUENCE supplement is targeted to support hair growth, with plenty of biotin and additional nutrients for an extra push.

HAIRFLUENCE is packed with biotin to promote healthy new hair and improve the condition of your existing strands. It also contains bamboo extract (which may help nourish vital tissues in your hair), collagen (which can speed cell growth), and keratin (a compound that may help repair broken strands with split ends).

Best for Nails: Natrol Biotin Maximum Strength Tablets

Weak nails that bend, crack, or split are frustrating to deal with. You’ll need a solid foundation of healthy nails if you want to keep your nails strong or even regularly get manicures, but that’s hard to do when you’re fighting against harsh chemicals from nail polishes and naturally brittle nails. A recent medical review of the science behind biotin revealed that oral biotin shows promising results in treating nail conditions. So, if you’re looking for stronger nails, you’ll want to check out Natrol’s Maximum Strength Biotin Tablets.

These tablets have helped hundreds of reviewers score healthy, shiny fingernails and toenails. They have an impressive 10,000 mcg of biotin per serving, and they’re 100 percent vegetarian for herbivores seeking stronger claws.

Best Gummy: Vitafusion Extra Strength Biotin Gummies

Anyone who struggles to remember to take their daily multivitamin can benefit from gummy vitamins. The fruit flavors and fun textures bring back the nostalgia of eating gummies as a kid, adding an element of fun that makes this daily ritual easier to remember. If you’re looking for a great biotin supplement in a nostalgic gummy formula, Vitafusion’s Extra Strength Biotin Gummies packs 5,000 mcg of biotin into just two candies.

These tasty supplements come in a natural blueberry flavor that will make you look forward to taking them daily. They’ve got just as much biotin as other formulas, and they’re a solid pick for anyone who has difficulty swallowing whole pills.

Best Organic: LifeGarden Naturals Whole Food Biotin Supplement

If organic foods, home products, and supplements are a priority for you, you’ll want to continue that trend with an organic biotin supplement. LifeGarden Naturals' Whole Food Biotin Supplement uses plant-based biotin to bypass industrial chemicals for a more holistic approach to biotin supplements.

This 2,500 mcg biotin supplement is free of pesticides, preservatives, residual chemicals, and other chemical additives that put a cramp in your organic style. The company’s ethical manufacturing promise guarantees that this supplement is produced in the United States and follows the Food and Drug Administration's guidelines for purity and potency. The only ingredients are biotin derived from Sesbania Agati trees and vegan cellulose capsules.

Best for Men: Zhou Nutrition Iron Beard Growth Supplement

Many men struggle with hair loss as they age, and suddenly noticing that your hair is disappearing can affect your sense of self. There are multiple methods you can try to prevent further hair loss and encourage growth, and Zhou Nutrition’s Iron Beard Growth Supplement may help fill out the hair on your face and your scalp.

Biotin is the all-star ingredient in this supplement. It promotes new growth and protects existing growth from breakage. Collagen, vitamins A and C, and folic acid round out this supplement for fuller, stronger hair.
