Bis-Glycinate 20 liquid contains iron bisglycinate, a chelated iron that is easy to absorb, gentle on the stomach and doesn’t cause gastrointestinal upset like those that contain ferrous sulphate can.  This liquid formula contains 20 mg of elemental iron in every tablespoon, and is enhanced with vitamins C, B6, B12 and folate, all cofactors that help in the absorption and assimilation of iron for the production of healthy red blood cells.
