Warning On Protein Shake Supplements

Chugging protein drinks to build muscle? A Consumer Reports test shows some shakes contain high levels of arsenic, cadmium and lead.


Protein drinks aren’t only for the Lance Armstrongs and Tom Bradys of the world anymore. According to a 2005 study in the journal Pediatrics, teenagers use them more than any other supplement. The problem: Consumer Reports recently tested 15 popular drinks and powders and found potentially dangerous levels of heavy metals in several of the products.

According to their report, drinking two or more of EAS Myoplex Original Rich Dark Chocolate Shakes, Muscle Milk Chocolate powders or Muscle Milk Vanilla Crème powders a day could put a person over their maximum daily limit. What’s more, eight of the 15 products tested contained enough lead in a single serving to require a warning label in the state of California. The reason they don’t: These products, like all vitamins and supplements, are not regulated or tested by the FDA. According to independent testing lab ConsumerLab.com, one in four dietary supplements have “quality problems.”

If you choose to take supplements, look for ones that are USP-verified. That means they’ve voluntarily submitted to tests for potency and purity. And remember, dietary supplements are meant to be just that: supplements. You might not be able to get all of your vitamins and minerals from your diet, but strive to come as close as possible.
