Are any of your clients interested in supplementing with creatine? Then they should know about the new testing done by ConsumerLab.com, an independent evaluator of products that affect health and nutrition. The tests found problems with the majority of creatine products sold in liquid, effervescent and chewable forms. No problems were found in the standard powder products.
The bottom line? Be realistic about the effectiveness of these products and skeptical about the contents—particularly of the newer forms. For more information on the tests and how to best choose and use these supplements, see this link.
