Mineral
Chromium
Chromium is a trace mineral that helps the body use insulin and process carbohydrate and fat. It is found in meat, wholegrains, nuts and some vegetables.
What it is
Chromium is a trace mineral that the body needs in very small amounts.
What it does
It helps insulin work and plays a part in how the body handles carbohydrate, fat and protein.
Good sources
Meat, wholegrains, nuts, some fruit and vegetables, and small amounts in many foods.
Deficiency and who is at risk
A true dietary deficiency is very rare and hard to identify, as chromium is needed in such tiny amounts and found in many foods.
Balance
Can you have too much?
Chromium from food is not known to be harmful. High-dose supplements are not generally recommended, as the benefits are unproven and very high intakes could cause problems.

Answers
Chromium: frequently asked questions
Do chromium supplements help with blood sugar or weight loss?
Chromium helps insulin work, but there is little good evidence that supplements improve blood sugar control or aid weight loss in people who are not deficient. A balanced diet provides what is needed.
Can I get enough chromium from food?
Yes. Chromium is found in meat, wholegrains, nuts and vegetables, and is needed only in tiny amounts, so a varied diet supplies enough.
