Proteins and heavy metals: what do you really need to know?

A recent Consumer Reports survey has cast a chill over the protein powder world. Of 23 products tested, 16 contained lead levels above the recommended daily limit. This has fueled doubts about the quality of certain brands and raised a serious question: what's really in the protein you consume every day?

At Pulse, we leave nothing to chance. And above all, we don't leave you in the dark. We explain.

What the report says

The study, published by Consumer Reports , an independent American organization, analyzed various proteins on the market—whey, plant-based powders, and blends—for heavy metals such as lead, cadmium, and arsenic. In 16 of the products tested, lead levels exceeded the levels deemed safe under California's Proposition 65 law. While this regulation is stricter than other international standards, the results raise a real question of trust.

Heavy metals can be found in powders via raw materials (especially plant-based, grown in contaminated soil), or introduced at certain stages of processing. But their presence is not inevitable. There are control methods, quality standards, and brands that choose transparency.

What we do at Pulse

At Pulse, every batch of protein powder is systematically tested by independent laboratories. We analyze for levels of heavy metals, contaminants, and other undesirable substances. Our results comply with current European standards, recognized for their stringency. The lead levels in our products are well below the permitted limits, and we ensure it stays that way.

Beyond testing, our approach is based on three pillars: rigorous supplier selection, complete traceability of raw materials, and certified manufacturing processes. This allows us to guarantee a high level of safety, without ever compromising on nutritional quality or taste.

Why it matters

Because consuming protein isn't just about "exercising" or "eating healthy." It's a daily gesture to take care of your body. And for that, trust in the products is essential. You have the right to know what you're consuming. And we have the duty to ensure it.

We've chosen transparency, rigor, and honesty. Because doing better is our commitment. And because you deserve better than vague labels or marketing promises.

In summary

Yes, some brands have been singled out for excessive lead levels. No, it's not inevitable. At Pulse, we do everything we can to ensure our products are safe, tested, and compliant.
