Groups of 12 Charles River CD virgin female rats were either supplemented with 25,000 IU/kg of vitamin A palmitate or not during the first 8 days of pregnancy and in the first experiment given a single dose of either 5 or 10 mg/kg of all-trans-retinoic acid (RA) on day 9 of pregnancy. In a second experiment, similar groups were given either 4 or 8 mg/kg RA daily from day 6 through day 15 so that each treatment with RA was given to vitamin A supplemented rats or nonsupplemented rats. The high systemic background of vitamin A increased the teratogenicity of the 10 mg/kg dose of RA given on day 9 by 50%, but reduced the teratogenicity of the 8 mg/kg dose given on days 6-15. The reasons for this paradox are discussed and related to the human propensity to self-medicate with megadoses of vitamins.
