As a leading supplier of high quality pasture fed cows whey, we’d like to ensure Defense Nutrition’s customers that our products are heavily tested and scrutinized  so as to first and foremost ensure food safety.  The monitoring and testing of our whey include heavy metal testing which has and continues to be routinely evaluated by accredited third party laboratories in accordance to AOAC methodology.  Analytical results for Defense Nutrition whey in this past year indicate:

Heavy metal Result Method
Arsenic <0.01 ppm SM3113D
Lead <0.05 ppm SM3113B
Mercury <0.05 ppm SM3112D
Chromium <0.1 ppm SM3113B
Copper <2 ppm AOAC969.23
Selenium < 1 ppm AOAC969.23
Silver < 0.02 ppm AOAC 969.23
Cadmium < 0.02 ppm SM3113B

How does the competition fare?

According to Consumer Reports magazine:

We found that three daily servings of the ready-to-drink liquid EAS Myoplex Original Rich Dark Chocolate Shake provides an average of 16.9 micrograms (µg) of arsenic, exceeding the proposed USP limit of 15 µg per day, and an average of 5.1 µg of cadmium, which is just above the USP limit of 5 µg per day. Concentrations in most products were relatively low, but when taking into account the large serving size suggested, the number of micrograms per day for a few of the products was high compared with most others tested.

What’s the worst offender? Consumer Reports says:

The samples of Muscle Milk Chocolate powder we tested contained all four heavy metals, and levels of three metals in the product were among the highest of all in our tests. Average cadmium levels of 5.6 µg in three daily servings slightly exceeded the USP limit of 5 µg per day, and the average lead level of 13.5 µg also topped the USP limit of 10 µg per day. The average arsenic level of 12.2 µg was approaching the USP limit of 15 µg per day, and the average for mercury was 0.7 µg, well below the USP’s 15 µg-per-day limit. Three daily servings of Muscle Milk Vanilla Crème contained 12.2 µg of lead, exceeding lead limits, and 11.2 µg of arsenic. A fourth product, Muscle Milk Nutritional Shake Chocolate (liquid), provided an average of 14.3 µg of arsenic per day from three servings, approaching the proposed USP limit.

    It would be helpful if you provided your data in micrograms for comparison.

    Does 1 ppm equal one microgram or are the relative measures different? A bit more detail with respect to the comparison between warrior whey and the offending products listed in the CR article.

    Thanks,

    alex

    Your data is misleading as the Warrior Whey readings are in ppm and the competition is in ug. You should do the calculation to show the metal amounts in a three serving WW size, as the others are displayed.

    It’s probably obvious to you, Ori, but for me (and probably many others) …

    How do we translate the “Parts Per Million” measurement of Warrior Whey to compare it to the “micrograms (µg)” measurements used by consumer reports?

    In fact, to best prove your point (marketing wise) it would make sense to say something like …

    “PPM is essentially equal to 1 microgram. And as you can see we have less than 0.05 ppm of lead … and the most popular competitor, Muscle Milk, had over 13.5 ppm of lead–exceeding the UPS limit of 10 ppm per day!”

    Something liek that, is that right?

    Best,
    Caleb

    Thanks for the info – good stuff! Can you show the ppm datahttp://defensenutrition.com/blog/2010/06/heavy-metals-in-whey-protein/ as mcg the way they did in the Consumer Reports article?

    Dear Ori,

    I purchased your Chocolate Warrior Whey, and I have always been looking for an organic, grass fed Whey protein powder.

    My only suggestion to make it better is to sell it in bigger sizes (2lbs +).

    I will be ordering again soon for the vanilla, chocolate, and peanut butter flavors.

    Thanks!

    These results are one of the main reasons why I use the Warrior products and they are the only nutritional supplements that I endorse and sell in my gym. I also know the level of commitment that Ori puts into all his supplements to assure that they are the best on the market today

    ppm = mg
    mg x 1000 = ug

    This makes your numbers pretty high.

    previous formula was not carried out far enough.
    the USP amounts determined to be safe are stated as mcg

    easiest thing to do is multiply 16 grams protein x ppm

    arsenic (16 x 0.01) = 0.16mcg
    lead (16 x 0.05) = 0.8 mcg
    etc

    I just purchased Warrior Whey for these reason. But, could you provide the results based on 3 servings a day and in micro-grams? These results do not help us compare to those tested by consumer reports.

    Ori & Defense Nutrition: Until you clarify the information on Warrior Whey in a manner that allows anyone to compare all protein powders based on 3 servings a day and results in micro-grams and not ppm’s, I will withhold purchasing additional cans of your product.

    My understanding from my anti-aging doctor is that virtually everybody who ingests whey protein becomes allergic to it (testing revealed I have developed this problem myself). This is why I use Sun Warrior rice protein. No product is perfect, however. One Sun Warrior vendor claims that the product does not cause stomach issues but I have read about at least one person that encountered this issue. But I tolerate it just fine.

    If someone has a reason to believe that I would not be allergic to the Defense Nutrition whey I would be interested to hear about it. Thanks.

    How about an egg protein. There are very few and most of those contain all sorts of contaminants due to the way they are processed.

    Comparing this to another whey supplier, Defense seems much better:

    However, I would still like to see the conversion from ppm to micrograms

    Go to a conversion website, its that difficult. Yes the conversion should have been made clear but ppm and micrograms (µg) are the same thing. You’re welcome Ori for settling the debate, especially since people were saying that were not going to buy the product until this was settled.

    1 microgram (µg) = 0.000001 gram
    1 gram = 1 gram

    1 microgram/gram = 0.000001/1 = 1/1000000 = 1 PPM

    So yes, microgram/gram is the same as PPM.

    Are all protein powders contaminated with toxic metals? Is this due to the processing part of the product? Why are there even minimal amounts of dangerous metals found in the protein powder? I don't understand.
