Thirty three percent of a ferrous fumarate is retained in the form of elemental iron, so for a 90 mg dose, we'd take 33% of 90mg which equals 29.7mg of elemental iron.
Molar mass of Fe-fumarate is 169.8 g/mol Atomic mass of Fe is 55.8 1 mol of Fe-fumarate is 169.8 g; 55.8 g of that is Fe2+. So, 100 mg of Fe-fumarate will have 100x(55.8/169.8)=32.8 mg of elemental...
Molar mass of Ferrous ascorbate is 408 g/mol Atomic mass of Fe is 55.8 1 mol of Ferrous ascorbate is 408 g; 55.8 g of that is Fe2+. So, 100 mg of Ferrous ascorbate will have 100x(55.8/408)=13.7 mg of...
Ferrous gluconate provides 12% elemental iron. For example if you take 100 mg ferrous gluconate you will get 12% elemental iron.Similarly Ferrous sulphate provides 20% elemental iron andFerrous...
