Does Biotin Help With Biotin is a B-vitamin used as a cofactor in metabolic pro...?

Evidence Summary

Biotin is a B-vitamin used as a cofactor in metabolic processes; one crossover RCT (PMID: 38688776) compared 5 mg oral biotin to 5% topical minoxidil for male hair growth, though no abstract was available to confirm outcomes. High-dose biotin supplementation has been documented to cause proximal renal tubular acidosis in at least one case report with rechallenge confirmation (PMID: 41835731). Biotin is also used as a reagent in many laboratory immunoassays, where exogenous supplementation can cause significant false-positive or false-negative interference across a wide range of clinical tests (PMID: 41876205).
