VeriMomIs biotin safe during pregnancy?
Biotin (vitamin B7, CAS 58-85-5) is not listed with a harmonised reproductive hazard (no H360/H361) in ECHA Annex VI and there is no authoritative safety assessment indicating reproductive toxicity from topical cosmetic use. Human clinical literature deals with oral supplementation and deficiency correction, not teratogenicity; no evidence of biotin as a reproductive toxicant was identified (ECHA Annex VI; PubMed; PubChem).

Frequently asked questions
- Is biotin safe during pregnancy?
- Biotin (vitamin B7, CAS 58-85-5) is not listed with a harmonised reproductive hazard (no H360/H361) in ECHA Annex VI and there is no authoritative safety assessment indicating reproductive toxicity from topical cosmetic use. Human clinical literature deals with oral supplementation and deficiency correction, not teratogenicity; no evidence of biotin as a reproductive toxicant was identified (ECHA Annex VI; PubMed; PubChem).
- Is biotin safe while breastfeeding?
- No harmonised classification or authoritative reports indicate biotin causes reproductive or lactation-related harm. Biotin is a normal constituent of human nutrition and is present in breast milk when supplemented orally; there is no evidence that cosmetic topical use poses a hazard to breastfeeding infants (PubMed; PubChem; ECHA registration information).
- Is biotin safe for baby skin?
- No evidence of developmental or reproductive hazard specific to infants. Mechanistic data do not indicate reproductive endocrine disruption. Dermal absorption of biotin (a small, water-soluble vitamin) from cosmetics is expected to be low/negligible in adults (therefore adult e = 0), but infant skin has higher surface-area-to-weight and a less mature barrier; accordingly exposure score is increased by +1 for babies (e = 1). No infant-specific studies showing harm from topical biotin were identified (PubChem; PubMed; ECHA).
- How does VeriMom score biotin?
- VeriMom scores biotin at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
