Question: Is there any evidence that chromium picolinate increases metabolism? Is it safe and what is the correct dosage?

Dr. Hibberd's Answer:

This supplement has been falsely marketed as an athletic enhancer and weight loss aid largely because of lack of FDA review. Numerous studies have not shown any effect on muscle growth or fat loss, and the alleged improvement in insulin resistance has not been supported by controlled trials. There is concern that this product may be associated with DNA damage and mutation, so I would recommend avoiding it for now. The amount of chromium needed to help the body utilize glucose is so small that supplementation is not really necessary, despite reports that food processing depletes some of our food of chromium. Save your money. There is too much potential risk with too little benefit, if any!
