Due to excessive chromium loss and marginal chromium intake, athletes may have an increased requirement for chromium. The maintenance of chromium stores via supplementation would promote optimal insulin efficiency, necessary for high-level athletic performance (Lefavi et al., 1992). Though chromium supplements have been purported to increase muscle mass and decrease body fat, the preponderance of evidence has not supported this claim. There is little information available on the long term use of chromium supplements, but at present, supplements within the ESADDI level do not appear harmful. The prudent course of action for athletes would be to ingest foods rich in chromium and perhaps take a mineral supplement containing no more than the ESADDI of chromium (Clarkson, 1997).
