35 Years.
One Mission.
Clean Protein.
We started with the plant. Every protein we make is traceable, tested, and built on three decades of expertise. Because to us, that is what clean really means.
Most brands test at the end.We manage safety from the start.
1
Field-level sourcing
We source peas from low-contaminant regions in North America, working directly with growers who meet our standards before a crop is ever planted.
2
Raw material testing
Every harvest is tested for lead, cadmium, arsenic, and mercury before it enters our facility. We do not wait until the end to find problems.
3
Proprietary processing
Our processing methods are designed to actively reduce lead and arsenic levels, not just pass them through. The protein gets cleaner at every stage.
4
Batch-level verification
Every batch generates its own data trail. Consistency is not claimed, it is measured and documented for full traceability.
5
Finished protein you can stand behind
Lead levels as low as 0.008 ppm, well below Prop 65 thresholds. Cadmium, arsenic, and mercury similarly controlled. And we are constantly improving.
Why PURIS Is a Safer Choice
Closed-Loop Supply Chain
We control the entire lifecycle, from seed selection to finished protein
Prevention, Not Detection
We prevent contamination at the source instead of testing for it after the fact
Identity-Preserved Sourcing
Every ingredient is traceable to named farms and verified growing partners
Proactive Standards
Internal safety targets that exceed regulatory requirements and industry norms
Transparent Data
Real testing results shared openly, not marketing claims
Continuous Improvement
Constantly refining methods to push heavy metal levels lower every year
The Numbers Behind
Every Batch
Protein makes up 90% or more of the typical nutrition powder. The journey to clean products starts here. Not all plant proteins are created equal.
Safety by the Numbers
Headlines and lawsuits have trained consumers to assume the problem is the protein. Our data tells a different story.
Heavy Metal Safety FAQ
Are pea proteins safe from heavy metals?
All plants naturally absorb trace minerals from the soil, including heavy metals like lead and cadmium. What matters is how much is present and whether steps are taken to keep levels low. PURIS actively manages heavy metals at every stage, from sourcing peas in low-contaminant regions to proprietary processing that reduces lead and arsenic. Our most advanced programs achieve lead levels as low as 0.008 ppm.
How does PURIS test for heavy metals?
Every batch is independently tested for four heavy metals: lead, cadmium, arsenic, and mercury. But testing is only part of the story. PURIS also manages contamination at the source through field-level sourcing, annual raw material testing, and processing methods specifically designed to reduce heavy metal levels. We do not just detect problems, we prevent them.
What makes PURIS different from other protein brands?
Most brands buy protein from commodity supply chains and test the final product. PURIS controls the full lifecycle. We started as an ingredient company, not a supplement brand. The protein itself, the quality, the amino profile, the sourcing, was the product before we ever put it in a bag. That closed-loop model is why we can deliver cleaner protein with full traceability.
