Chromium is an essential mineral that is not made by the body and must be obtained from the diet.
Chromium is important in the metabolism of fats and carbohydrates. Chromium stimulates fatty acid and cholesterol synthesis, which are important for brain function and other body processes. Chromium is also important in the breakdown (metabolism) of insulin.
The best source of chromium is brewer's yeast, but many people do not use brewer's yeast because it causes abdominal distention (a bloated feeling) and nausea.
Other good sources of chromium include the following:
Black pepper, butter, and molasses are also good sources of chromium, but they are normally consumed only in small amounts.
Chromium deficiency may be seen as impaired glucose tolerance. It is seen in older people with type 2 diabetes and in infants with protein-calorie malnutrition. Supplementation of chromium helps with management of these conditions, but it is not a substitute for other treatment.
Because of the low absorption and high excretion rates of chromium, toxicity is not common.
The Food and Nutrition Board at the Institute of Medicine recommends the following dietary intake for chromium:
Adolescents and Adults
The best way to get the daily requirement of essential vitamins is to eat a balanced diet that contains a variety of foods from the food guide pyramid.
Specific recommendations depend on age, gender, and other factors (such as pregnancy). Women who are pregnant or producing breast milk (lactating) need higher amounts. Ask your health care provider which amount is best for you.
