During pregnancy, iron bisglycinate, ferrous fumarate, and folic acid tablets are commonly recommended as iron supplements. Among these, iron bisglycinate is particularly noted for its effectiveness, though some individuals may experience diarrhea when taking ferrous gluconate at normal doses. It’s essential to consider the balance of nutrients, including calcium citrate, which is often provided at a dosage of 760 mg in various supplements. Maintaining a proper intake of calcium citrate, especially at 3.5g, can support overall health during pregnancy. Therefore, when choosing an iron supplement, it’s crucial to evaluate options like iron bisglycinate and ferrous fumarate, while also ensuring adequate calcium citrate intake for optimal nutritional support.
