Chromium is a trace mineral that works with insulin to help regulate and maintain normal amounts glucose in the blood. It also plays a role in carbohydrate, fat, and protein metabolism. Chromium can be found naturally in foods and also comes in a variety of supplemental forms.
|Age Group||Adequate Intake (micrograms/day)|
|Pregnancy 18 years or younger||29||n/a|
|Lactation 18 years or younger||44||n/a|
Severe chromium deficiency is likely very rare. As chromium works closely with insulin, a deficiency of this mineral can produce symptoms similar to those seen in people with diabetes and can worsen glycemic control in people with pre-existing diabetes.
It is difficult to consume toxic amounts of chromium from dietary sources alone. However, harmful levels of the mineral can potentially be ingested in the form of supplements. Daily dosages of 50-200 mcg are believed to be safe. The Food and Nutrition Board of the Institute of Medicine has not established a Tolerable Upper Intake Level.
A daily intake of over 1,200 micrograms has been reported to cause kidney, liver, and bone marrow damage in one person. In another case report, a person taking daily dose of 600 mcg over a 6-week period was enough to cause damage. You should talk to your doctor before taking more than 200 mcg. Chromium toxicity may be more likely in people who already have liver or kidney disease
Many foods contain a small amount of chromium. In general, whole grain breads and cereals and meats are all good sources. The content of chromium in many foods can be affected by how food is gown and processed. Here is a sample of common foods that contain chromium:
