What is biotin?
Biotin is vitamin B7, a water-soluble vitamin found naturally in eggs, meat, fish, seeds, nuts, and certain vegetables. It plays a role in keratin synthesis, which is the structural protein that makes up hair, skin, and nails. That connection is why biotin became one of the most marketed ingredients in the beauty supplement category.
Biotin dosage: what the numbers on labels mean
Biotin is measured in micrograms (mcg). A practical note on reading labels: check the biotin amount per serving on the Supplement Facts panel rather than the package headline. Some products display the total bottle content or a prominent number on packaging that does not reflect the per-serving dose.
Stacking biotin with collagen: a complementary approach
Biotin and collagen address hair and nail structure at different levels and are not redundant. Biotin supports keratin synthesis, the process that builds the protein making up the hair shaft and nail plate. Collagen contributes amino acids involved in the connective tissue that supports hair follicles and the nail bed. Taking both is a reasonable approach to supporting hair and nail health from more than one angle.
Two products in this guide, Nature's Bounty Tropical Citrus Gummies and MAELYS Supercharged Liquid, combine both ingredients in a single daily serving. For customers who prefer separate supplements, any collagen product from Ulta's assortment can be paired with a standalone biotin gummy or capsule.

Frequently asked questions
Does biotin help with nail strength, not just hair?
Biotin plays a role in keratin synthesis, and keratin is the structural protein in both hair and nails. Zinc, included alongside biotin in several products on this list, also supports nail health through its role in protein synthesis and cell division.
Should I take biotin and collagen together for hair and nails?
Biotin and collagen are not redundant. Biotin supports keratin synthesis (the protein in the hair shaft and nail plate), while collagen contributes amino acids involved in connective tissue supporting hair follicles and the nail bed. Taking both together addresses hair and nail health from more than one angle.
How long does it take for biotin supplements to show results on hair and nails?
Hair grows approximately half an inch per month on average, and nail growth is slower. Most supplement brands and beauty editorial sources suggest allowing three months of consistent daily supplementation before evaluating results, as this timeline reflects the pace of hair and nail growth cycles.
Can I order biotin supplements at ulta.com?
Yes. All five products in this guide are available at ulta.com. Ulta Beauty Rewards members earn points on supplement purchases.
What is the best form of biotin to take?
There isn't one form of biotin proven to be better than another for most people. Biotin is commonly available as biotin (vitamin B7) in tablets, capsules, and gummies, and the body can absorb these forms effectively. For most people, the best option is a product that provides an appropriate amount of biotin and fits easily into their daily routine.
Should you take biotin everyday?
Biotin is a water-soluble vitamin, and most people can get enough through a balanced diet, so daily supplementation isn't necessary for everyone. If you choose to take a biotin supplement, follow the product's recommended serving rather than assuming a higher dose will provide better results.
