When choosing a plant-based protein, people often think it’s a matter of taste, price, or the amount of protein per serving. But there’s one factor that’s almost never mentioned on the label—and it’s probably the most important one for your long-term health: the presence of heavy metals.
At Provea, “Tested for heavy metals” isn’t just another marketing claim. It’s the first item on our list, and here’s why.
The disturbing finding: half of protein powders exceed the limits
In January 2025, the Clean Label Project —an independent nonprofit organization—released the results of an analysis of 160 protein powders from 70 of the best-selling brands, representing approximately 83% of the market. The samples underwent tens of thousands of tests at an independent laboratory.
The result: approximately 47% of the products exceeded a regulatory threshold (California’s well-known Proposition 65, one of the strictest in North America) for at least one toxic heavy metal—lead, cadmium, arsenic, or mercury.
And that's where it becomes relevant to you, if you eat plant-based foods.
Why plant-based proteins are the most vulnerable
That’s the counterintuitive part of the story. People often choose plant-based protein for health reasons… yet it’s actually the category that poses the greatest risk.
According to the same study:
"Organic" versions were not spared—often quite the opposite, in fact, because the majority of the organic products tested were plant-based.
The reason is simple and has to do with biology: plants naturally absorb heavy metals from the soil through their roots. When the soil has been depleted or contaminated by industrial activity, mining, or certain fertilizers, these metals become concentrated in the plant—and thus in the final powder.
The surprising detail: flavor matters too
Chocolate-flavored powders contained, on average, four times as much lead and up to 110 times as much cadmium as the vanilla versions. That should make you think twice before ordering your next chocolate shake.
What "Tested for heavy metals" actually means
Testing a batch for heavy metals is neither a mandatory nor a free process. Many brands skip this step because it costs time and money, and because there is no requirement to list the results on the packaging.
Having a product tested means having each batch analyzed to ensure that the levels of lead, cadmium, arsenic, and mercury remain below recognized safety thresholds. It’s a voluntary decision—a choice to be transparent rather than something you’d expect to see listed on the bill.
This is exactly the kind of commitment that sets a product meant for the whole family— including children and teenagers—apart from a generic product bought on a whim.
Provea the Competition: A Comprehensive Comparison
Testing for heavy metals is just the starting point. But a truly pure protein is judged by everything it contains—and, above all, by what it doesn’t contain.
| Criterion | Provea | Several others |
|---|---|---|
| Heavy metals | Laboratory-tested | Often untested |
| Sugar | No added sugar | Frequent added sugar |
| Additives | No additives | Additives present |
| Vegan certification | Certified vegan | Variable |
| Gluten | Gluten-free | Variable |
| GMOs | Non-GMO | Variable |
| Protein per serving | 20 g of plant-based protein | Variable |
| List of ingredients | Short and easy to read | Often long |
Here are a few details about what each box contains:
No added sugar
Many protein products mask their earthy taste with sugar—sometimes several grams per serving. Provea , on the other hand, Provea with a flavorful base, so there’s no need to hide anything.
No additives and a short ingredient list
If the ingredient list reads like a chemistry lesson, that’s rarely a good sign. The fewer ingredients there are, the easier it is to know exactly what you’re eating. Our blends are based on chickpeas and omega-3s, enriched with natural superfoods.
20 g of plant-based protein
Enough to support energy, recovery, and satiety—without having to double the portions.
Certified vegan, gluten-free, and GMO-free
Clear standards, not "probably." That means a single formula can work for the whole family, regardless of individual dietary restrictions.
“Animal instinct. Plant energy.” — designed for the whole family
That’s the whole philosophy behind Provea. We wanted the energy and performance typically associated with protein, but derived from plants, without compromising on purity.
As the first Quebec brand to offer a protein solution tailored to children, teens , and their parents, Provea designed to fit seamlessly into busy days: a smoothie in the morning, a spoonful in your coffee, or a snack after school or a workout. Made in Canada, with no refined sugar or additives.
Simple, clean, and effective. That's it.
Frequently asked questions
Do all protein powders contain heavy metals?
Traces may be present in just about anything that grows in the ground, including so-called "healthy" foods. What matters isn't total absence—it's staying below recognized safety thresholds, and verifying this through laboratory testing rather than just hoping for the best.
Why are plant-based proteins considered riskier than whey?
Because plants absorb heavy metals from the soil through their roots. Independent studies have found, on average, higher levels of lead and cadmium in plant-based proteins than in whey-based proteins. This is why testing is so important for plant-based brands.
Does flavor really make a difference?
Yes. Chocolate versions tend to contain higher levels of heavy metals than vanilla versions, due to the cocoa itself. This is another factor to consider when making your choice.
Is Provea for children?
Yes. Provea specifically formulated for children, teenagers, and adults, precisely because the standards we set for ourselves—tested for heavy metals, no added sugar, no additives—are the ones we want for the whole family.
