Relationship between the biological availability and solubility rate of reduced iron.

Solubility rate determinations were conducted on electrolytic iron and hydrogen reduced iron and carbonyl iron samples to study the correlation of biological availability and solubility. There was excellent correlation for the hydrogen reduced iron and electrolytic iron samples,. The carbonyl iron samples showed a direct relationship between solubility and bioavailability, but these data were not numerically equivalent to data from other types.
