Brittle, slow-growing nails are a common frustration that sends many women toward supplements promising support from within. Biotin—a B vitamin brands market for hair, skin, and nail health—has become the go-to ingredient, but the supplement aisle offers dizzying variety in dose, format, and added ingredients.
How we choose
This roundup highlights eight biotin-based options available now, ranging from 5,000 mcg to 10,000 mcg doses and spanning softgels, gummies, vegan capsules, and fast-dissolve tablets. Whether you prioritize a low price point, a plant-based formula, or a flavor you actually want to take daily, these products address different practical needs without overstated promises.
Our 8 Picks
Nature's BountyBiotin Hair Skin and Nails Vitamins, 120 Softgels | Supports Healthy Hair, Skin and Nails, 10,000mcg
What it is
A biotin supplement in rapid-release softgels providing 10,000 mcg biotin per serving.
Why it's worth it
This is a no-frills, high-dose biotin option at a low price point, in a traditional softgel that is a good fit for women who prefer a straightforward supplement. It is marketed for hair, skin, and nails support, and Nature's Bounty states biotin also supports energy metabolism. The 120-count bottle gives a substantial supply, so it suits someone who wants to reorder less often.
Caveat
At 10,000 mcg, this is a high-dose formula; a lower-dose supplement may suit biotin newcomers better.
VitafusionGorgeous Hair/Skin & Nails Multivitamin Gummy Vitamins + Biotin & Antioxidant Vitamins C&E/Raspberry Flavor (45 Day Supply) America’s Number One Gummy Vitamin Brand, 135 Count (Pack of 2)
What it is
A raspberry-flavored gummy multivitamin for hair, skin, and nails, sold as a two-pack, with 5,000 mcg biotin per three-gummy serving.
Why it's worth it
This two-pack is a good fit for someone who is already comfortable with a gummy beauty multivitamin and wants to buy in larger quantity. Each three-gummy serving delivers 5,000 mcg biotin plus vitamins C and E, and Vitafusion lists the formula with no artificial flavors, sweeteners, synthetic dyes, or high-fructose corn syrup. Buying the two-pack means fewer reorders over time.
Caveat
Because it is a multi-pack, the upfront price is higher than a single-bottle supplement.
OLLYHair Skin and Nails Gummies, Undeniable Beauty, Biotin - 120 Count
What it is
A grapefruit-flavored gummy supplement with biotin, vitamins C and E, and keratin for hair, skin, and nail support.
Why it's worth it
This 120-count bottle is well suited to someone who wants a two-month supply of a beauty gummy. OLLY's formula includes keratin, a structural protein, alongside biotin, and OLLY states the gummies are made with no synthetic flavors or colors. The grapefruit flavor also sets it apart from the berry and strawberry options in this lineup.
Caveat
This is a general beauty gummy, not a nail-specific treatment.
HUMHair Strong Capsules, Hair Growth Support, 30 Count | Folic Acid, Fo-Ti Root Extract, Biotin, Zinc & B12, Women & Men, Vegan Capsules, Non-GMO
What it is
A vegan capsule supplement for hair growth support, with biotin, zinc, folic acid, vitamin B12, and Fo-Ti root extract.
Why it's worth it
This is a good fit for a plant-based supplement routine, with vegan capsules and non-GMO ingredients. It goes beyond biotin by adding fo-ti root extract, zinc, folic acid, and vitamin B12, and HUM states the blend supports hair wellness and a healthy appearance. The compact 30-count bottle suits travel or desk-drawer storage.
Caveat
It is primarily marketed for hair support, so nail growth is not the central focus.
Sports ResearchBiotin 10,000mcg w/Coconut Oil, 120 Count Plantgels™ | Max Strength Vegan Biotin (Vitamin B7) for Healthy Skin and Hair Support | Non-GMO, Gluten & Soy-Free, 120 Servings
What it is
A high-dose biotin supplement in vegan Plantgels, formulated with coconut oil for hair and skin support.
Why it's worth it
This is a good fit for women who want a 10,000 mcg biotin dose in a vegan, plant-based capsule. The coconut oil and Plantgel format distinguish it from standard softgels, and it is non-GMO, gluten-free, and soy-free. Sports Research states biotin contributes to energy metabolism, giving the supplement an everyday wellness angle alongside hair and skin support.
Caveat
At 10,000 mcg, this is a very high biotin dose, so it is not the most conservative starting point.
Nature MadeMaximum Strength Biotin 5000 mcg Softgels, 120 Count | Biotin Hair Skin and Nails Vitamins, Dietary Supplement with Biotin for Adult Women and Men, 120 Day Supply
What it is
A maximum-strength biotin softgel providing 5,000 mcg biotin per serving.
Why it's worth it
This is a good fit for a middle-dose option: 5,000 mcg is a middle-strength alternative to the 10,000 mcg bottles in this lineup. The 120-count bottle is labeled as a 120-day supply, so it suits someone who wants a low-maintenance daily softgel. Nature Made says the formula is gluten-free and free of synthetic dyes, with colors derived from natural sources.
Caveat
It is still a higher-dose biotin, not a low-dose maintenance option.
ZHOUHairfluence Supplement - 60 Veggie Capsules (Pack of 1) | Vegan Biotin Supplement for Hair Growth for Men & Women, Supports Stronger & Healthier Hair & Nails
What it is
A vegan biotin supplement in capsules with keratin, B vitamins, and a proprietary blend, marketed for hair and nail support.
Why it's worth it
This is a good fit for women who want a biotin supplement built around a more complex beauty blend. Hairfluence includes keratin, B vitamins, and a proprietary Lustriva blend that Zhou says supports stronger, healthier-looking hair and nails. The veggie-capsule format keeps it suitable for a plant-based routine.
Caveat
Because Lustriva is a proprietary blend, exact amounts of each ingredient are not listed on the product page.
NatrolBiotin 10000mcg, 4X Faster Dissolve Supplement for Healthy Hair, Skin and Nails for Those Low in Biotin, Plus Energy Metabolism Support, 60 Tablets, Up to a 60 Day Supply
What it is
A strawberry-flavored fast-dissolve biotin tablet providing 10,000 mcg biotin.
Why it's worth it
This is a good fit for anyone who struggles with capsules, because the tablet dissolves in the mouth with no water needed. Natrol states the strawberry-flavored formula is 100% drug-free and can be taken anytime, anywhere, making it one of the more convenient options in the roundup. It also gives nail-focused readers a tablet format at a budget-friendly price.
Caveat
The tablet dissolves in the mouth, so the strawberry flavor is noticeable and may not appeal to everyone.
