- As for this organic mineral stuff, I'd imagine this refers to
- chelating agents complexing the minerals in question. For instance,
- CaF2 (eg in toothpaste) is inorganic, whereas calcium citrate (one of
- the forms of calcium recomended as a supplement for post-menopausal
- women to prevent osteoporesis) is calcium chelated by an organic
- compound (citrate.) In some instances, depending on solubility, various
- ionic compouns simply won't disolve very much when ingested, for instance,
- magnesium phosphate, though dissolved in the low pH conditions in the
- stomach, will precipitate in the duodenum as bicarbonate neutralizes
- stomach acid. As such, with most of the mineral in insoluble form,
- little is absorbed. Other minerals dissociate readily and are readily
- absorbed in "inorganic form", for instance, potasium or sodium.
- Many mineral supplements are in the form of amino acid
- chelates, which don't associate so tightly with the ions in question.
