Hematic Formula is a 100% vegan Food supplement that is intended to supply nutrients needed to maintain optimal and support blood health. Iron is an important nutrient essential for the synthesis of hemoglobin and is part of some of the enzymes needed for cell respiration. B vitamins also support hemoglobin production. Vitamin C has been shown to enhance the absorption of iron. Hematic Formula is not constipating like iron-salt supplements can be.
