The evidence behind prenatal vitamins

Some nonprescription vitamins marketed toward fraught women contain 20 or more vitamins or minerals. Too see if these vitamins had the necessary skill to back up their use, researchers with the DTB scoured published materials to determine the potency of their claims. Folic acid — the gold standard of prenatal vitamins — made the baseball swing. Along with vitamin D, it ’ s the only supplement the DTB recommends for all meaning women. Folic acid, a synthetic version of vitamin bc, helps prevent neural tube defects ( NTDs ), such as spina bifida and anencephaly, or a parturition defect where a child is born without parts of the genius or skull .

This international relations and security network ’ deoxythymidine monophosphate to say that some women may benefit from these vitamins, but there international relations and security network ’ thyroxine enough inquiry to suggest all meaning women need to take them. “ For most women who are planning to become pregnant or who are meaning, complex multivitamin and mineral preparations promoted for function during pregnancy are improbable to be needed and are an unnecessary expense, ” the DTB newspaper concludes. While women in developing countries may lack these authoritative nutrients in their diets, women in countries like the United Kingdom and United States have access to these vitamins through their diets. The best way to get necessity nutrients is through the foods we eat, not necessarily through a supplement diligence that has fiddling and loose oversight by the U.S. Food and Drug Administration ( FDA ).
