The precautionary limit of about 10,000 IU/day rests on a single 1995 observational cohort — a thin evidence base, but one worth respecting because the potential harm (teratogenicity) is severe. Do not take a separate vitamin A supplement alongside a prenatal in pregnancy. Beta-carotene forms do not carry the same risk because conversion is regulated.
