Monitor ferritin, serum iron, and transferrin saturation every 6–12 months. If deficient, supplement with ferrous bisglycinate 25–50 mg daily with vitamin C to enhance absorption. Take iron away from calcium supplements.
Why this interaction occurs
Ozempic reduces food intake and slows gastric emptying, decreasing iron absorption from dietary sources. Reduced gastric acid production further impairs non-heme iron conversion. Women of reproductive age and individuals with prior low iron stores are at highest risk of developing iron deficiency anemia.
Evidence
Evidence level: moderate.
