Chromium picolinate linked with reduced carbohydrate cravings in people with atypical depression
..."Chromium is an essential trace mineral whose main function
is to work with insulin to metabolize carbohydrates, fats and proteins. When chromium is bound to picolinic acid to create chromium picolinate, absorption in the body is significantly improved. Recently the U.S. Food and Drug Administration recogni...
