Consumer Reports is warning people who work out to exercise caution when taking protein shakes.
Their investigation studied 15 different protein powders and drinks and found that they could poison you with toxic heavy metals if you drink them too often. The dangerous metals include arsenic, cadmium, mercury and lead. The drinks causing the most concern are EAS Myoplex Original Rich Dark Chocolate Shake, and two Muscle Milk powders - the Vanilla Crème and Chocolate which only needed 3 servings.
