It is formulated to be the best whole food iron supplement available due to blend of Hawaiian Spirulina and iron bisglycinate. This form of iron has great absorption of iron and does not cause constipation and/or stomach distress, common to the conventional iron treatments. Hawaiian Spirulina contains important co-factors for iron absorption, including Vitamins A, K, B1, B2, B3, B5, B6, Folate, B12, Manganese, and Chromium. Vitatree Whole Food Iron Complex contains no added fillers or flow agents like magnesium stearate. Vitatree Whole Food Iron Complex is in an easy to swallow vegetarian capsule, but can be mixed into any liquid, or into a smoothie or food if preferred. Vitatree Whole Food Iron Complex helps to supply the body with iron, an important essential mineral as the body does not inherently produce iron on its own, therefore it needs to be supplied by the diet or by supplementation. Almost every cell in the body requires iron. As part of haemoglobin, iron helps to transport oxygen throughout the body and plays an important role in the normal function of muscle tissue. Athletes, growing children and teens for proper muscle development, therefore especially need iron.
