Consumer Reports: High Levels of Heavy Metals Lead and Cadmium Found in Muscle Milk Products

For their July issue of this year, Consumer Reports have tested CytoSport’s popular Muscle Milk and a bunch of other protein supplements for heavy metals, and the picture isn’t pretty. Going by the maximum limits proposed by the U.S. Pharmacopeia, two Muscle Milk products were found to contain excessive levels of heavy metals (when consuming 3 servings a day): their Chocolate powder contains too high levels of cadmium and lead (along with considerable levels of arsenic), and their Vanilla Creme is too high in lead.

And CytoSport’s  products  aren’t the only bad boys of the bunch: according to the report, three servings of EAS’ Myoplex Original Rich Dark Chocolate Shake will also give you slightly more cadmium and arsenic than it really should, going by the same standards.

Consumer Reports  also tested twelve other protein supplement products, and found some levels of heavy metals in several of those as well, but the Muscle Milk and Myoplex products were clearly the losers of the test.

This is pretty bad news both for the manufacturers of these products and their customers, and it is obviously something that is going to be dealt with in some way. Will we see products being recalled? I’d say that’s definitely possible. I’d also be surprised if we didn’t see public statements from these companies, as this is clearly a biggie and something they absolutely need to comment on. After all, in the age of Web 2.o and social media, you really can’t expect to get away with stuff like this. And I’m very interested to hear what these people have to say.

I could also see this flare up into a new debate on both the safety and efficacy of protein supplements. After all, the Consumer Reports article also state their views on how much protein they people “need” (take a wild guess as to the gist of it…) – which is of course something that has nothing to do with how safe these products are.

Rest assured: Not all protein supplements have been found to contain lead, mercury, cadmium, arsenic or any other heavy metals. However, this report does highlight the need for a deeper look into the practices of nutritional supplement manufacturers, and as users of these products I think we all welcome that. Personally, I’d rather pay a little more for my protein drink than risk the effects of excessive heavy metal exposure.

    It’s getting really tough to avoid all these toxins.
    I found this website that shows you how to test for heavy metal at home, so I started testing stuff around my house just be sure. If anyone else is interested just Google: “home-health-chemistry”.
    Keep safe, T.

    My son and i have been drinking muscle milk for over two years. I’ve used it as a pre-work out and post work out drink as directions suggest. Chocolate has been our favorite.

    I’m wondering if I need to go get some blood work done to see if I have any high levels of heavy metals in my system now.

    Anyone talking about long-term or possible side affects of consuming high levels of heavy metals?

    Why isn’t a company that is supposed to be looking out for our health checking their products properly? How do heavy metals even get into protein powders?

  4. I have been following the amounts of toxins in our environment for the last year or so and found a solution called “Nutritional Cleansing.” Nothing but pure quality ingredients that support the removal of heavy metals, pesticides, toxins, and other neuro toxins from our entire body. It is proven.
    PS. the heavy metals enter the products because they are already in the cows that are producing the whey protein that is a major ingredient. Our agricultural system is almost entirely toxic so you have to use “clean cows” in addition to superior quality ingredients. Please consider learning more at my website: It will change you life dramatically.
