Diabetes Diet

Chromium

Chromium is a metal and an essential trace mineral. Chromium is found in some foods, such as meats, animal fats, fish, brown sugar, coffee, tea, some spices, whole-wheat and rye breads, and brewer's yeast. It is marketed in supplement form (capsules and tablets) as chromium picolinate, chromium chloride, and chromium nicotinate.

Summary of the research findings

There are scientific controversies about the use or need for chromium supplementation by persons with diabetes. First, it is difficult to determine, including through tests, whether a person has a chromium deficiency. Second, it is not known whether it is beneficial to take chromium supplementation in diabetes, and there is a lack of rigorous basic science studies to explain or support any evidence of benefit. In sum, there is not enough evidence to show that taking chromium supplements is beneficial for diabetes.

Side effects and other risks

At low doses, short-term use of chromium appears to be safe in the general adult population. However, chromium can add to insulin in its effects on blood sugar; this might cause the blood sugar to go too low. Possible side effects at low doses include weight gain, headache, insomnia, skin irritation, sleep problems, and mood changes. High doses can cause serious side effects. The foremost concern for persons with diabetes who use chromium is the development of kidney problems. Other possible effects include vomiting, diarrhea, bleeding into the gastrointestinal tract, and worsening of any behavioral or psychiatric problems.
