British Industrial Biological Research Association. The metabolism of EDTA. Food and Cosmetics Toxicol. 1964; 2:741-745 (Dec.). (2670) [The treatment of Pb poisoning with iv injections of Ca edathamil (CaEDTA) has been studied extensively. Since, however, small quantities of EDTA salts are also used as food additives, the question posed itself whether prolonged intake of small quantities of EDTA salts could adversely affect the mineral metabolism of the body. A review of available evidence indicates that the amount of EDTA likely to be ingested by an adult eating food containing EDTA in the necessary technical quantities will chelate only a minute fraction of the available dietary Ca and, if CaEDTA is used, this depletion becomes negligible. Also, the reduction of Fe absorption that results from the use of EDTA is very small and probably occurs only in states of positive Fe balance.]
