Are Protein Powders Contaminated with Lead? Here’s the Truth

You may have seen the Consumer Reports (CR) article claiming that protein powders are contaminated with heavy metals like lead. According to CR, two-thirds of the 23 protein powders they tested exceeded their so-called “safe levels,” with some plant-based products allegedly containing over 1,000 times more lead than their recommended daily limit.

Sounds alarming, right? Let me clear this up.

First, there’s absolutely nothing to be concerned about with these findings. And second, no protein manufacturer is adding lead—or any other heavy metal—to their products. The trace amounts CR found come from a completely natural and unavoidable source: the soil.

Where the Lead Actually Comes From

Lead and other minerals occur naturally in the earth’s crust. Plants absorb them from the soil as they grow, and that’s where the trace levels in protein powders come from—especially in plant-based varieties like pea or rice protein.

Even animal-based proteins such as whey, casein, milk, and beef protein can contain trace metals. The cows eat the grass, the grass grows in the soil, and the soil contains minerals and heavy metals. It’s a natural chain, not contamination.

No supplement company is “adding” lead during production. It’s simply a byproduct of nature.

Why the Consumer Reports Data Is Misleading

Here’s where CR went off the rails: They decided that 0.5 micrograms (mcg) of lead per day was the maximum “safe” level. That number didn’t come from any federal guideline; it’s based on California’s Prop 65, which many experts criticize for setting unrealistically low limits on naturally occurring substances.

By contrast, the FDA’s own research shows that adults can safely consume up to 12.5 mcg of lead per day through their diet without any health or safety concerns.

To put that into perspective, here’s how much lead the FDA has measured in everyday whole foods:

• 1 cup of sweet potatoes: 13 mcg
• 1 cup of Brussels sprouts: 6 mcg
• 2 carrots: 5 mcg
• 1 tomato: 2 mcg
• 1 cup of strawberries: 2 mcg
• 1 large apple: 2 mcg

So by CR’s standard, nearly every fruit and vegetable in your kitchen would be considered “unsafe.”

Fearmongering for Clicks

Consumer Reports’ headline-grabbing claims are classic fear-based marketing. Saying “your favorite protein powder has the same amount of lead as a cup of Brussels sprouts” doesn’t generate clicks. But saying “your favorite protein powder exceeds safe lead levels by 1,000 times” does.

And when they quoted Dr. Nicholas Burd as saying that supplement users “put themselves at greater risk,” they failed to mention that the same could be said for anyone who eats fruits or vegetables. 

Both contain trace amounts of heavy metals—and neither poses a real health risk.

Here's the Real Takeaway

Here’s what CR should have told you:

The trace lead levels found in protein powders—whether plant-based or dairy-based—are no higher than what you’d find in common fruits and vegetables.

If you’re using a high-quality, science-backed protein like Pro JYM or Iso JYM , you can feel confident knowing your supplement is safe, effective, and thoroughly tested for purity.

There’s no need to fear your protein powder. Focus instead on training hard, fueling right, and staying consistent—that’s where the real results come from.

FAQs

Q: Are protein powders safe to use daily?

Yes. Quality protein powders are tested for purity and meet or exceed FDA safety standards. The trace amounts of minerals and metals present come naturally from soil and are not harmful in normal dietary amounts.

Q: Are plant-based protein powders more contaminated than whey?

Plant-based powders tend to have slightly higher natural mineral content because plants absorb metals directly from soil. However, these levels are still safe and similar to what you’d find in everyday vegetables.

Q: What is the best protein powder to take?

I recommend using Pro JYM or Iso JYM . Both provide a complete, high-quality protein blend for muscle growth and recovery—and every batch is tested to ensure purity and safety.
