In depth
About this supplement
What Is Biotin?
Biotin is a water-soluble B vitamin, also called vitamin B7. Its structure is two fused rings with a short fatty-acid tail, and that tail is how it clips onto the enzymes it serves. Food supplies most of what we get, from eggs, liver, nuts and seeds, and gut bacteria make some as well.
How It Works in the Body
Biotin is a carrier for carbon dioxide. Five human enzymes, the carboxylases, use it to move a single carbon unit onto another molecule. Each of those enzymes is inert until biotin is bonded to a lysine within it.
Those five reactions sit at the start of fatty acid synthesis, in the breakdown of certain amino acids, and in the pathway that builds new sugar when food runs short.
What It Supports
- Hair, skin and nails: Biotin supports the keratin-rich tissue of hair and nails.
- Energy metabolism: Biotin plays a role in normal energy metabolism.
- Fat synthesis: Through acetyl-CoA carboxylase, biotin supports the body's own production of fatty acids.
- Amino acids: It contributes to the breakdown of branched-chain amino acids.
Who It May Suit
This suits people who eat few eggs, nuts or organ meats, and anyone who wants a single B vitamin rather than a full B complex. The capsule is cellulose and the rest is rice flour, so it works for vegetarians and vegans.
Good To Know
Biotin is water-soluble, so what the body does not use leaves in the urine. One practical point: at supplement amounts biotin can skew laboratory tests built on a biotin-streptavidin step, including some thyroid and cardiac ones, giving readings that run high or low. Tell your provider and the lab that you take it before any blood work.

FAQ
Common questions
What is biotin?
An essential water-soluble B vitamin, also known as vitamin B7. Chemically it is a bicyclic ring with a five-carbon side chain, and that side chain is what attaches it to enzymes. It is found in eggs, liver, nuts, seeds and legumes, and this capsule provides 1,000 mcg per serving.
How does it work in the body?
Biotin is bolted onto five enzymes by a dedicated enzyme of its own, holocarboxylase synthetase, which forms a bond between biotin and a lysine in each carboxylase. Once attached, biotin ferries a carbon dioxide unit into the reaction. Without it, those five enzymes sit inactive, whatever else is available.
What makes this formula different?
It is biotin on its own at 1,000 mcg per serving, rather than a multi-ingredient hair and nail blend. The capsule is cellulose, the filler is rice flour, and ascorbyl palmitate and silicon dioxide keep the powder flowing.
Who is it for?
It suits people eating few eggs, nuts, seeds or organ meats, and anyone who wants one B vitamin rather than a full complex. Raw egg white binds biotin tightly, so people who eat raw eggs regularly may take an interest. It is vegetarian and vegan.
What should I know before taking it?
The main thing is laboratory testing. Biotin at supplement amounts interferes with immunoassays that use a biotin-streptavidin step, including some thyroid and cardiac tests, which can read high or low as a result. Tell your provider and the laboratory that you take it before any blood draw.
