Preeclampsia
Supplements studied for preeclampsia.
Overview
Calcium has the strongest supplement evidence for preeclampsia prevention, with 18 studies showing that daily supplementation during pregnancy—typically 500 to 2000 mg—may roughly halve risk, especially in people with low dietary calcium. Magnesium sulfate, studied in 9 trials, is the established treatment to prevent seizures in preeclampsia when given by injection, though this is a medical intervention rather than oral supplementation.
Vitamin B9 (Folate) (6 studies) does not appear to prevent preeclampsia reliably, and Fish Oil (5 studies) shows mixed results on risk reduction. Vitamin D (3 studies) has unclear preventive benefit, though some guidelines suggest supplementation during pregnancy for broader maternal-fetal outcomes.
