Synergy
What is happening. Both iron bisglycinate and B12 are essential for red blood cell production. Deficiency in either causes anemia.
Mechanism. Iron Bisglycinate is incorporated into heme for hemoglobin synthesis. B12 is required for DNA synthesis in rapidly dividing erythroid precursors in bone marrow.
Recommendation. If anemic, check both iron bisglycinate and B12 status. Supplementing only one may not resolve anemia if both are deficient.
