So you wouldn't agree with:
Chromium facilitates the conversion of blood glucose to glycogen by insulin. Glycogen is stored in the liver and muscles. In the liver, low glycogen levels may result in low blood glucose levels. This can cause fatigue, mental fatigue, inability to concentrate, and light-headedness. The glycogen stored in the skeletal muscles is used for strenuous physical activities. When competitive athletes refer to "hitting the wall" at their exhaustion point, they are referring to the point at which the body's muscle glycogen stores are depleted, resulting in mental and physical exhaustion. Because of its ability to increase liver and muscle glycogen stores, chromium is listed as one of the 33 ergogenic substances considered unethical or illegal by the International Olympic Committee which when taken orally, may increase muscle levels of creatine phosphate and enhance energy performance and exercise performance. [Williams, MH. The use of nutritional ergogenic aids in sports: Is it an ethical issue? International Journal of Sports Nutrition 1994;4:120-131.]
Any one else have an opinion?
