Iron Protein Succinylate

Iron Protein Succinylate (IPS) is a specialty iron compound, not a whole food, so it does not contain macronutrients (carbohydrates, fats) or dietary fiber in meaningful quantities. Key compositional data: Iron content: approximately 10–12% elemental iron by weight, delivered as ferric iron (Fe³⁺) complexed with succinylated casein protein carrier. A standard therapeutic dose of 40 mg IPS provides approximately 4–5 mg elemental iron. The succinylated casein matrix constitutes the majority of the compound's mass (~88–90%) and contributes negligible but trace amounts of protein-derived amino acids (predominantly glutamic acid, aspartic acid, and lysine residues altered by succinylation). Bioavailability notes: The protein-bound ferric iron is released selectively in the intestinal lumen at pH >7 (duodenum and jejunum), bypassing gastric acid exposure, which significantly reduces oxidative irritation to the gastric mucosa. Bioavailability of elemental iron from IPS is estimated at 20–40% relative absorption efficiency, comparable to or exceeding ferrous sulfate in populations with normal and compromised gut function. No co-factors (vitamin C, B12, folate) are inherently present in the compound itself; concurrent dietary intake of ascorbic acid can further enhance iron uptake. No significant levels of other vitamins or minerals are present within the IPS compound itself.
