Should You Worry About Lead In Protein Powders?
“Protein Powders and Shakes Contain High Levels of Lead”
Now that’s a headline that’ll stop you in your tracks.
You’re telling me something I’ve been using 1–2 times a day for the last 15 years might contain a toxic compound? Yikes. Definitely not what you want to hear.
Here’s a quick breakdown of what the researcher’s found—and what I think you should do about it.
So… Is There Lead in Your Protein Powder?
Here’s what stood out from the latest round of independent testing:
1. Most products failed the lead test.
Out of 23 powders and shakes tested, over two-thirds exceeded the recommended daily limit for lead—in a single serving.
2. Plant-based options were the worst offenders.
Products made with pea protein had the highest lead levels, while animal-based powders generally fared better.
3. Other heavy metals showed up too.
Several powders also contained measurable amounts of cadmium and arsenic—both of which can be harmful with long-term exposure.
4. It’s worse than it used to be.
Compared to tests done 10+ years ago, more products now have detectable (and often higher) levels of contamination.
5. There’s no real oversight.
Because protein powders are classified as dietary supplements, manufacturers aren’t required to test for contaminants—or prove safety—before hitting the market.
What Should You Do About It?
This kind of headline is jarring—but let’s not freak out just yet. Here’s how to think about it:
1. Don’t be afraid of protein powder.
Yes, this news is worth taking seriously. But the tone of the article? A little much.
There are safe, high-quality options out there—and for most people, protein powder is still one of the easiest, most effective ways to support lean muscle, improve body composition, and stay full between meals.
I use it and recommend it every day.
2. If you’re using it a lot, double-check your source.
If you’re having a scoop (or two) every day—or taking multiple supplements—it’s smart to look for third-party testing. Sites like Labdoor, NSF, or Informed Choice can help you verify quality and purity.
Why?
Because most supplement companies aren’t required to test for contaminants.
And while they’re not trying to harm anyone, they are trying to cut costs. Testing is expensive. Quality control takes effort. And if skipping those steps means bigger profit margins? Some will.
That’s why third-party testing is worth five extra minutes on Google.
3. Know the lack of regulation is insane.
Back in the 1980s, there were only a few thousand supplements on the market.
Today? Over 90,000.
And yet they’re still regulated less strictly than food. No required testing. No pre-approval It’s time for a reset.
Consumers are relying on these products more than ever—so the rules should catch up.
Final Thoughts
Protein powder is still one of the most incredible food inventions of the modern era.
Even though most people get enough protein to avoid deficiency, the vast majority don’t get enough to support a lean, strong, high-functioning body—especially in a food environment built around hyper-palatable, ultra-processed options. That’s part of why 70% of Americans are overweight or obese.
Protein powder is one of the most effective tools to fight back—but only if you use it wisely.
Don’t skip it—just double-check your sources.
Best,
John
