VeriMomIs histidine safe during pregnancy?
L‑histidine (CAS 71‑00‑1) is an endogenous/essential amino acid with no harmonised reproductive classification on ECHA Annex VI and no evidence in the regulatory aggregated sources of reproductive toxicity. PubChem GHS listings include non‑harmonised notifications (H302, H315, H319, H332) which are NOT harmonised and therefore do not indicate reproductive hazard; no SCCS/CIR or harmonised CLP reproductive flags were identified. Topical exposure is expected to be low but measurable for adults (small polar molecule), so exposure score is 1.

Frequently asked questions
- Is histidine safe during pregnancy?
- L‑histidine (CAS 71‑00‑1) is an endogenous/essential amino acid with no harmonised reproductive classification on ECHA Annex VI and no evidence in the regulatory aggregated sources of reproductive toxicity. PubChem GHS listings include non‑harmonised notifications (H302, H315, H319, H332) which are NOT harmonised and therefore do not indicate reproductive hazard; no SCCS/CIR or harmonised CLP reproductive flags were identified. Topical exposure is expected to be low but measurable for adults (small polar molecule), so exposure score is 1.
- Is histidine safe while breastfeeding?
- No data indicate histidine is a reproductive or lactation toxicant; no harmonised classifications for reproductive effects. Maternal topical exposure would be low but potentially measurable, so exposure scored as 1.
- Is histidine safe for baby skin?
- No infant‑specific evidence of hazard or mechanism. Because infant skin has higher absorption potential, the adult exposure score (1) is increased by +1 for baby skin, giving an exposure score of 2; histidine itself is a small, water‑soluble amino acid and not expected to be a developmental toxicant.
- How does VeriMom score histidine?
- VeriMom scores histidine at 93/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
