Mandur Bhasma (Iron Oxide Ash)
Mandur Bhasma is a calcined iron oxide preparation in Ayurveda that provides bioavailable iron to support hemoglobin synthesis and red blood cell production. It works through iron absorption in the duodenum via DMT1 transporters, helping treat iron deficiency anemia.

Origin & History
Mandur Bhasma is derived from iron oxide, processed through traditional Ayurvedic methods involving purification and calcination to create a fine ash.
Historical & Cultural Context
Mandur Bhasma has been traditionally used in Ayurveda for its blood-enhancing and digestive benefits, highlighting its cultural significance.
Health Benefits
- Enhances blood health by increasing red blood cell production, crucial for preventing anemia. - Supports liver health by promoting detoxification processes, which can improve overall vitality. - Strengthens bones by improving mineral density, reducing the risk of osteoporosis. - Aids in digestion by supporting the production of digestive enzymes, enhancing nutrient absorption. - Improves skin health by reducing oxidative stress, leading to a clearer complexion. - Balances mood by supporting neurotransmitter production, which can alleviate symptoms of anxiety. - Boosts energy levels by enhancing iron metabolism, crucial for reducing fatigue.
How It Works
Mandur Bhasma provides elemental iron in an oxidized form that gets reduced to ferrous iron (Fe2+) in the acidic stomach environment. The iron is then absorbed through divalent metal transporter 1 (DMT1) in duodenal enterocytes and bound to transferrin for transport to bone marrow. There, it incorporates into heme groups during hemoglobin synthesis and supports erythropoiesis.
Scientific Research
Research on Mandur Bhasma suggests potential benefits for anemia and digestive health, but further studies are necessary to validate these findings.
Clinical Summary
Limited modern clinical research exists on Mandur Bhasma specifically, with most evidence coming from traditional Ayurvedic texts and small observational studies. One study of 30 anemic patients showed improved hemoglobin levels after 8 weeks of treatment, though the study lacked proper controls. Traditional use suggests efficacy for iron deficiency anemia, but large-scale randomized controlled trials are needed. Most safety and efficacy data extrapolated from general iron supplementation research.

Preparation & Dosage
The recommended dosage of Mandur Bhasma is 60 mg to 125 mg per day. Consult a healthcare provider before use.
Synergy & Pairings

Safety & Interactions
Mandur Bhasma may cause gastrointestinal upset, constipation, and nausea similar to other iron supplements. It can reduce absorption of tetracycline antibiotics, levothyroxine, and quinolone antibiotics when taken concurrently. Contraindicated in hemochromatosis, hemosiderosis, and thalassemia due to iron overload risk. Safety during pregnancy and lactation not established through modern clinical trials.
