Biotin, Explained: The Anchor Ingredient Here
Biotin is by far the most recognisable ingredient in Gelanic's formula, with a genuine structural role in keratin production.
Understanding what biotin's research actually supports helps set realistic expectations for this formula.
What biotin genuinely does
Biotin (Vitamin B7) plays a well-documented role in the production of keratin, the structural protein that makes up skin, hair and nails. This role is summarised by the NIH Office of Dietary Supplements.
Where marketing tends to outpace the evidence
Most of the strongest research on biotin and hair/nail growth involves people with an actual biotin deficiency, which is relatively uncommon in people eating a varied diet. Popular marketing often implies dramatic improvements for anyone, regardless of whether they are deficient to begin with.
Applying this to Gelanic
Biotin is one of the five ingredients in Gelanic's formula, genuinely connected to keratin production, though its exact amount is not published on the pages we reviewed.
