Poisonous Protein Powders

In July, Consumer Reports magazine tested 15 protein powders for levels of 4 heavy metals:

  1. Lead
  2. Arsenic
  3. Mercury
  4. Cadmium

At certain levels, these heavy metals can be poisonous.

The worst thing is that they will accumulate over time so if you continue to use these products, you’ll accumulate more and more poisons in your system and they may reach a level that causes negative health effects.

What are these brands and what are the levels of these poisons?

Check out this chart first then I’ll explain more below:

First of all, notice that these are all based on 3 servings, not 1 serving.

So if you’re doing 1 serving a day, then you’ll be well below the daily limits for all of these brands.

But remember, these heavy metals accumulate, so ideally you want NONE!

Here are the daily limits for each metal:

  • Arsenic – 15 ug
  • Cadmium – 5 ug
  • Lead – 10 ug
  • Mercury – 15 ug

Amounts exceeding these levels are in BOLD in the chart.

By looking at the chart, we can see that the EAS Myoplex Shake and Muscle Milk products are the worst.

So I’d avoid these things at all costs.

And there are so many alternatives that there’s no reason at all to use these products.

One product I use is Hemp Protein vs. Whey.

No, you don’t get high from it (unfortunately).

I still use Whey occasionally, but find myself taking Hemp protein more often as it’s a) closer to nature and b) has protein, fibre and healthy fats, making it a more balanced food.

Plus, they keep coming out with new flavours vs. the original sludge flavour, so it’s actually tasty now!

Either way you go, I always recommend rotating brands – don’t use the same brand all the time.

This way, you can insulate yourself from potentially overloading your system with heavy metals or other toxins contained in these products.

And, your body doesn’t develop an intolerance to a particular brand and it’s components.

Another brand you can check out for Whey protein is Prograde.

They’re not the cheapest whey protein (which is probably a good thing) but they’ve got some videos taking you into their labs and I like to see the behind the scenes action when I can – it just makes me trust them a bit more.

Plus, I know the registered dietitian in charge of the whole operation (Jayson Hunter) and he’s a good guy and he’s also a martial artist himself.

I blog quite often and I really thank you for your
content. Your article has truly peaked my interest.
I am going to take a note of your site and keep checking for new details about once per week.
I subscribed to your RSS feed too.

Hello, There’s no doubt that your website could be
having browser compatibility issues. Whenever I look at your site in Safari, it looks
fine however, if opening in IE, it has some overlapping issues.
I merely wanted to provide you with a quick heads up!
Other than that, great blog!


Hello Eric,

I saw in your nutrition-itsu that you recommend certain protein drinks during and post-training. But I saw that you use protein supplements in these. To tell the truth I’m not a big fan of protein powders, and I’m very hesitant to use them, and you state in your nutrition-itsu that natural is best, so why promote these?

So, I wanted to ask you what are your thoughts on these:



Thanks for the Reply Eric. Okay I will finish off the Huge bottle of AMP I have but the problem is I actually have one more huge bottle in stock left. Haha. But I’ll be sure to start switching it up.

Again thanks.

Hey Eric I noticed you listed GNC’s Pro Performance Amp Amplified Wheybolic Extreme 60 “Chocolate”, I was wondering were you only just referring to this chocolate flavor brand or the whole brand it self? Because I am currently using this brand but only the fruit punch and vinilla Flavors. I was just wondering. Thank you.


Hey Chia,

I can’t tell you – I didn’t do the testing, Consumer Reports did, but you could probably assume with a good likelihood of being right that it’s the same across flavours.

Regardless – finish it off then avoid it the next time you buy. You won’t die from one bottle.


Good to remember read the labels! on everything !. We all have been brain washed to think it’s a health supplement it must be good for me.That goes for all so called health items. Thanks Eric

scary info there, especially considering how many stream some of these protein powders are! thanks for the alternative suggestions though; i have some hemp sample packs in my pantry and i’m gonna go give one a whirl right now!!



Great Stuff I Like new reports on this topics, thats why I avoid aspartam in this products (now I’ll must look on this poisons too 🙂 hard but helth is on the line)
MuscleTech and SixStar brands use aspartam in ther whey powders (produce cancer in long run).
Erics advice on rotating brands is very good, because our body is biology and we acumulate all things.

Prograde is one brand and one which looks promising is brand from coach Charles Poliquin, but pricey too.

Take care


Cytosport has MSG in their products, that is proven to kill braincells by attaching to them and overstimulating them until they die


Yeah MSG is never a good thing consumed in large quantities – definitely a neuro-toxin. Would avoid that stuff as much as possible!

What about Randy Coutures line of supplements? He has a Whey protein powder. his website is www.xcap.tv


Randy will put his name on anything if you give him a $100,000 cheque… 🙂

I have no idea how the purity is because I didn’t do the testing!

But keep switching stuff up man and you’re good.


thanks for the info eric.i uesd to swear by muscle tech products until now.ive also tried muscle milk,thought it was pretty tasty,yet over priced.i know adrian peterson from the viqueens uses that stuff,maybe thats why he fumbles so much.gonna try hemp protein.


this link shows all the flaws made in that article about all the protien powders.

muscle tech and six star supplements are the same products under diff brand names owned by the same company. glad to see six star protein is one of the cleaner ones on the list. which means regular vanilla muscle tech protein would have the same results.


Good information. Have there been any studies on the whey isolate products offered on the market. They are touted to be ultra-high quality, are they really any better?

I have been using ISOFLEX whey protein isolate for approx 2 months, after a workout or training session to help with a quick recovery. What is your opinion of this type of product?


Hey Guys,

About specific brands like ISOFLEX, ISOPure, GNC, etc…

It’s hard to say…

But my best advice is to continue to switch brands – don’t stick with one brand all the time.

And definitely try some alternatives, like Hemp, or Brown Rice protein powders to keep your body from developing a food intolerance.


IsoPure is supposed to be very clean. Any thoughts on that?

This makes me glad that I got my boyfriend off of Muscle Milk and on Cytogainer, though I bet that has poison too.


lol it’s same exact company.. Just has simple carbs added in it


I had never even heard of this until i got the email. good to know. although I’ll probably be switching brands anyway do you know if the regular GNC whey is just as toxic? That’s what I have been using for a while.
