The Different forms of Iron Natural Organic Heme Iron Iron bound to natural hemoglobin or myoglobin Synthetic iron from chemical supplements plants and dairy and otherwise chemically bond synthetic iron Fe++ There are two forms of bio-available Iron

Organic Heme Iron vs Synthetic Iron Synthetic iron must be dissolved before uptake with low absorption and side- effects due to reactive free iron remaining in the gut. Heme iron is easily absorbed with 5-12 times higher bio-availability than synthetic iron. Fe++ Absorption % Intestine Fe++ Absorption % Intestine Fe++

Efficient and Well Tolerated Heme Iron highly efficient with low acid content in the stomach Heme Iron uptake is great with Medications as antacids and PPI Heme Iron will not irritate the gut as there is no reactive free iron Heme Iron will not cause oxidative stress in the body system. Absorption (typical) Heme Iron Synthetic iron Heme Iron 20-25% 2-4% Side-effects (typical) 20-30% Equal to Placebo 2-4%

FerroCare Organic Iron 18 mg Heme Iron, Fe ++ Iron integrated hemoglobin Dosage 1 tablet/day 18 mg Heme Iron % uptake 4.0 mg Fe ++ absorbed equals to 4.0 mg Bio-Available Iron 100 mg synthetic iron, Fe ++ Ferrous fumarate, sulphate Dosage 1 tablet/day 100 mg synthetic iron 2 - 4% uptake 3.0 mg Fe ++ absorbed equals to 3.0 mg Bio-Available Iron Synthetic Iron tablet
