Pregnancy health
Supplements studied for pregnancy health.
Overview
Iron has the most studies (16) among supplements tracked for general pregnancy health, but current evidence is limited and more research is needed before any reliable benefit can be concluded. Probiotics (2 studies) and Vitamin D (2 studies) are rated as possibly effective, though the underlying trial data remain modest.
Selenium (2 studies) has insufficient evidence, and iodine (1 study) lacks enough data to determine benefit. Overall, supplement evidence for broad pregnancy health outcomes is still developing. The heatmap and evidence reviews below provide supplement-level detail.
