Chromium Picolonate For Weight Loss

Chromium picolinate gained attention for its purported effects on weight loss. Advocates, such as authors Julian Whitake and Carol Colman of the book "Shed 10 Years in 10 Weeks," touted the weight loss properties of a taking chromium picolinate supplement. Part of the basis for these claims was the role that chromium plays in glucose metabolism. However, the results of scientific evidence are mixed at best. If you are considering taking chromium picolinate, consult your doctor first.

What Is Chromium Picolinate?

Chromium is an essential trace mineral, required by the body for sugar metabolism and improving insulin's ability to maintain normal levels. As a dietary supplement, you will find chromium sold as chromium picolinate because it is an easier form for the body to absorb. It is found in a variety of foods including broccoli and grape juice. Unlike other more familiar nutrients, more research is needed to determine a recommended daily allowance for chromium. The adequate intake for healthy body function is 35 mcg in men and 25 in women in individuals less than 50 years. The AI decreases by 5 mcg for both sexes after age 51.

Evidence

Current scientific evidence finds no basis for use of chromium picolinate for weight loss. A 2007 study by the Grand Forks Human Nutrition Research Center in North Dakota studied of supplementation with 200 mcg of chromium picolinate, the dosage commonly found in weight loss claims. After 12 weeks, researchers found that chromium picolinate did not affect body weight or fat. These findings are further supported by a 2010 study by the Yale-Griffin Prevention Research Center in Connecticut. Researchers found no changes in body mass index in participants after 24 weeks of supplementation.

Other Areas of Research

While evidence may not support chromium picolinate for weight loss, it may influence other areas that may have a positive effect on your weight. A 2008 study by Louisiana State University found that supplementing with chromium picolinate reduced food intake and cravings in experiments done with rats. Other research has focused on chromium picolinate's effect on blood glucose. A 2006 study published in "Diabetes Technology and Therapeutics" found that supplementation reduced the incidence of complications of diabetes while reducing cholesterol and triglyceride levels.

Guidelines for Use

The weight loss claims for chromium picolinate have not been evaluated by the U.S. Food and Drug Administration. However, the U.S. Federal Trade Commission determined that there is no scientific basis for its use for weight or fat loss. Drugs.com cautions that you should discuss its use with your doctor if you are taking diabetes medication, stomach acid reducers or beta blockers for blood pressure control.
