Most medications for RLS also pose risks to a developing fetus. Women most at risk for developing RLS during pregnancy are those with low levels of dietary folate and/or iron. This should be considered even before getting pregnant. Prenatal vitamins that include folate and iron supplements will help reduce RLS symptoms during pregnancy, but folate is better absorbed in foods (whole grains, cereals, and breads than it is in pill supplements; coffee decreases absorption and vitamin C increases absorption of folate from foods.
