Reacted Iron 29 mg by Ortho Molecular Products

Heavy periods with low Ferritin or a dipping Hemoglobin on a CBC is the classic scenario where iron bisglycinate shines. It also fits frequent blood donors, pregnancy planning or second/third trimester under clinician care, vegans on restrictive diets, endurance athletes, and post-bariatric surgery patients. If Proton Pump Inhibitors (acid-blockers) or celiac reduce absorption, this gentler form often works when ferrous sulfate doesn’t. The 29 mg here is a practical daily dose for maintenance or mild deficiency; established anemia usually needs a higher or clinician-directed schedule.

Ferrous bisglycinate is iron bound to two glycine molecules, which helps it pass through the gut with fewer reactions to food and less irritation than ferrous sulfate. Once absorbed, iron rebuilds hemoglobin (the oxygen carrier in red blood cells) and myoglobin in muscle, and feeds mitochondrial enzymes that make ATP, your cell’s energy currency. Hepcidin (a liver hormone that gates iron absorption) rises with inflammation and with too-frequent dosing, which is why this form and smart scheduling improve uptake and tolerability.

Take one capsule daily, ideally away from calcium-rich foods, coffee, or tea, which block absorption. A small snack is fine if empty-stomach iron upsets you. Vitamin C (a glass of citrus or 250–500 mg) can improve uptake. Some clinicians use every-other-day dosing to work with hepcidin and reduce nausea. Expect Hemoglobin to start rising within 2–4 weeks and Ferritin to climb over 4–12 weeks, then continue several months to refill iron stores.

Skip iron unless advised if you have hemochromatosis, thalassemia, repeated transfusions, or active infection. Separate by at least 2 hours from levothyroxine, zinc or magnesium supplements, and by 4 hours from tetracycline or fluoroquinolone antibiotics and oral bisphosphonates; iron blocks their absorption. Long-term use of Proton Pump Inhibitors can blunt iron uptake—monitor Ferritin, Hemoglobin, and Transferrin Saturation to be sure you’re responding.
