Supplementation with magnesium during pregnancy can have health benefits for both mother and baby; however, the quality of evidence is mixed, and large, well‐designed randomized controlled trials are needed to draw firm conclusions.[1][2][3][4][5][6][7][8][9]
Importantly, adverse effects of magnesium are rare, and supplementation with magnesium before or during pregnancy appears to be safe for mother and baby.[1][2][7][9] That said, women who are pregnant or planning to become pregnant should consult their doctor for advice before starting to supplement with magnesium.
