Is your protein drink toxic?
Ever heard of heavy metals in protein drinks? I hadn't until I saw this new report in the July issue of Consumer Reports (CR). CR looked at 15 protein powders and drinks and tested multiple samples for arsenic, cadmium, lead, and mercury.

Results show all of the drinks had at least one sample with one or more of these contaminants. And three products particularly concerned CR because the levels of arsenic, cadmium, or lead in three daily servings were more than the limits proposed by the USP (United States Pharmacopeia): EAS Myoplex Original Rich Dark Chocolate Shake, Muscle Milk Chocolate powder, and Muscle Milk Vanilla Crème. The report says those metals can have toxic effects on several organs in the body.
