Secondly, chromium as a mineral functions as a glucose tolerance factor, but the question is, what amount is appropriate as a supplement and can it be toxic?
Chromium is involved in the production of insulin and the release of glucose's energy from cells. Taking a chromium supplement will not increase the production of insulin unless your diet is deficient in chromium. Your body releases insulin from your pancreas in response to an elevated blood sugar level. Recent research does not support taking a chromium supplement for persons with diabetes or pre-diabetic insulin resistance.
It is not recommended to use chromium picolinate to control blood sugar levels. There is no proof that chromium supplements can help treat or prevent diabetes and other health problems. Methods to assess chromium amounts in the body are lacking, but chromium is stored in hair and blood (serum). However, hair analysis is not a valid method to analyze nutritional status of chromium or any other nutrient.
It is relatively easy to get safe and adequate amounts of chromium (50-200 micrograms per day) by eating a variety of foods like brewer's yeast, calf's liver, American cheese and wheat germ.
People who take chromium picolinate supplements may suffer health problems rather than improved health. Although claims of weight loss, lowered cholesterol and reversal of diabetes are unfounded, researchers have shown that chromium supplements damaged cell chromosomes which are the blueprints for a cell's function and reproduction. It is generally thought that cancer starts with a change to the genetic material in a cell causing it to grow and reproduce without restraint.
