There have been over twenty clinical studies with chromium supplementation in diabetics. In some of these studies of type 2 diabetes, supplementing the diet with chromium was shown to decrease fasting glucose levels, improve glucose tolerance, lower insulin levels, and decrease total cholesterol and triglyceride levels, while increasing high density lipoprotein (HDL) cholesterol levels. Although there are also studies that have not shown chromium to exert much effect in improving glucose tolerance in diabetes, there is no argument that chromium is an important mineral in blood sugar metabolism.
Although there is no recommended daily allowance (RDA) for chromium, it appears that we need at least 200mcg each day in our diet. People with diabetes need to supplement 200 to 400mcg per day. Chromium polynicotinate, chromium picolinate, and chromium-enriched yeast are all suitable forms.
