How This Protocol Works

Simple Explanation

Iron deficiency anemia occurs when the body lacks enough iron to produce adequate hemoglobin for red blood cells. The result is fatigue, weakness, and reduced oxygen delivery to tissues. This protocol focuses on effective iron repletion.

•Iron supplementation is essential—choose ferrous bisglycinate (chelated iron) for better absorption and fewer GI side effects than ferrous sulfate. New research shows every-other-day dosing may be more effective than daily dosing due to hepcidin rhythms.

•Vitamin C dramatically increases iron absorption—take 200mg with your iron supplement. Avoid taking iron with coffee, tea, or calcium, which block absorption.

•Lactoferrin is an iron-carrying protein from milk that's well-tolerated and may be especially helpful in pregnancy or those who can't tolerate traditional iron.

•B12 and folate deficiencies often coexist with iron deficiency and are also needed for red blood cell production.

Expected timeline: Hemoglobin increases within 2-4 weeks. Full iron store replenishment takes 3-6 months of continued supplementation. Recheck ferritin to confirm adequate repletion.

Important: Always identify the cause of iron deficiency (dietary, menstruation, GI bleeding, malabsorption).

Clinical Perspective

Iron deficiency anemia (IDA) results from inadequate iron for hemoglobin synthesis. Causes include blood loss, inadequate intake/absorption, or increased requirements. Iron status: ferritin < serum iron < transferrin saturation < hemoglobin.

•Iron supplementation (A-grade): Ferrous bisglycinate (chelated) has superior bioavailability and GI tolerance vs ferrous sulfate. Recent evidence: alternate day dosing may improve absorption by avoiding hepcidin-mediated inhibition (PMID: 28930496). Dose: 50-100mg elemental iron every other day.

•Vitamin C (A-grade): Reduces ferric (Fe3+) to ferrous (Fe2+) iron, maintaining solubility in alkaline duodenum. Increases absorption 2-4 fold. Take 200mg with iron dose. Avoid concurrent calcium, tannins, phytates.

•Lactoferrin (B-grade): Iron-binding glycoprotein with receptor-mediated uptake (LfR). RCTs show equivalent efficacy to ferrous sulfate with better tolerance, especially in pregnancy (PMID: 17244668).

•Vitamin B12 (A-grade): Check serum B12; deficiency causes megaloblastic anemia that may coexist. Vegetarians/vegans at high risk. Methylcobalamin or cyanocobalamin 1000mcg daily.

•Folate (A-grade): Required for thymidylate synthesis in erythropoiesis. Deficiency causes macrocytic anemia. Methylfolate (5-MTHF) preferred for MTHFR variants.

Monitoring: Reticulocyte count (response in 7-10 days), hemoglobin (rises 1-2 g/dL per month), ferritin (target >50-100 ng/mL for full repletion).

Refractory cases: Consider IV iron if oral fails, check for H. pylori (reduces absorption), celiac disease, or ongoing blood loss.
