Other name(s):

trivalent chromium, chromium picolinate

General description

Chromium is an essential trace metal. It helps control your blood sugar. It also helps insulin work well. You also need it to break down and store carbohydrates, fat, and protein. 

Medically valid uses

Chromium deficiency is rare in people. Studies of using chromium to treat blood sugar and type 2 diabetes don't have definite results. Research is ongoing.

Recommended intake

Chromium is measured in micrograms (mcg). Listed below are the adequate intake (AI) levels for chromium.

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.

Side effects, toxicity, and interactions

A high intake of chromium in your diet doesn’t cause serious side effects. But you should check with a healthcare provider before taking it. This is vital if you’re pregnant or breastfeeding.

If you have diabetes, chromium supplements could change how much medicine you need. They may also lower your blood sugar levels. Check your blood sugar levels closely if you start taking them.
