glucose tolerance and type 2 diabetes don't have definite results. Research is ongoing.

The amount of chromium in your body declines with age.
When you take it by mouth, chromium is not absorbed well. Many chromium products are
chelated. This means that the chromium binds to another chemical that helps it absorb.
The National Institutes of Health says the dietary intake of chromium can't be determined.
This is due to agricultural and manufacturing processes. Below are approximate amounts
of chromium in some foods.
