It is unlikely, however, that chromium supplementation will aid in fat loss unless one is either an athlete undergoing intensive training, or one is severely deficient in chromium before beginning the supplementation. As it pertains to life extension, it is likely that chromium is just a part of the larger subject of insulin resistance. Anything that can reduce the problem of insulin resistance, and bring blood sugar levels down to a moderately-low and stable level, will reduce the problems of aging. IRON Iron supplements have been popular for decades, and many people require them. Many recent studies, though, have linked iron to all kinds of biological damage.
Excessive iron can cause heart and liver disease and significant brain damage.
In 1992, an entire supplementary issue of the Annals of Neurology was devoted to reports of numerous scientific studies implicating iron in Parkinson's Disease and other degenerative brain disorders. The most popular example of oxidation damage is rust. Rust occurs when highly-reactive free radical iron reacts with oxygen. The same thing can happen in the human body. Many types of brain, liver, kidney and cardiovascular damage are literally due to rust.
