What does chromium do?
Chromium is an essential trace mineral needed for insulin function. Supplementing with chromium may be of modest benefit to some people with type 2 diabetes. One study suggests it may help people with reactive hypoglycemia. Although touted for weight loss, the evidence is weak. (See What It Is and What It Does). -
How much chromium should I take?
The daily requirement for chromium ranges from 11 mcg in young children to 45 mcg in lactating women. These amounts can be obtained from the diet (see Adequate intake and Chromium from food).
