This corpus does not contain a verified metal measurement for prenatal vitamins, so vitamin products are not graded and no brand is named. Methylmercury guidance values are on the mercury page.

The 24 September 2020 FDA statement lists pregnant women and their developing fetuses, women planning to become pregnant, and nursing women and their newborns and infants. FDA is not recommending removal of existing amalgam that is in good condition unless removal is considered medically necessary. FDA statement.
