Iron Bisglycinate and Vitamin A, a synergy.
Vitamin A improves iron bisglycinate mobilization from stores and enhances erythropoiesis. Combined supplementation is more effective than either alone for anemia.

Synergy
What is happening. Vitamin A improves iron bisglycinate mobilization from stores and enhances erythropoiesis. Combined supplementation is more effective than either alone for anemia.
Mechanism. Vitamin A mobilizes iron bisglycinate from ferritin stores in the liver and spleen. It also stimulates erythropoietin production and supports iron bisglycinate incorporation into hemoglobin during erythropoiesis.
Recommendation. Supplementing both is more effective for iron bisglycinate-deficiency anemia than iron bisglycinate alone, especially in developing countries.
