Active Iron Pregnancy, a non-constipating iron supplement that is suitable throughout pregnancy and during breastfeeding. Active Iron Pregnancy supports iron levels throughout pregnancy and is specially formulated to help prevent constipation. Active Iron Pregnancy is clinically proven to have x2 better absorption than the gold standard iron supplement, ferrous sulfate*. There is an increased need for iron when pregnant. During this time, the amount of blood in your body increases by 30-50%. This increases the requirement for iron and vitamins in your body as they are needed to make haemoglobin, which carries oxygen to other cells in your body. Iron is essential to life, especially during pregnancy. It contributes to the reduction of tiredness and fatigue and also plays an important role in normal energy metabolism, cognitive function and immune function. Research shows that many women do not have sufficient iron in their diet to meet their daily needs and this is also true during pregnancy, especially during the second and third trimesters.
