Beyond Compliance
Next-Level Heavy Metal Transparency in Plant Protein
Your customers expect clean labels. We help you deliver them with data-backed control over lead, cadmium, arsenic, and mercury in every PURIS pea protein ingredient.
Is the problem the protein or the system?
Protein powders have become synonymous with heavy metal contamination. Headlines, lawsuits, and third-party reports have trained consumers and brands to assume the problem lies with the protein itself.
But 3rd party testing data reveals a different story. Heavy metal levels vary dramatically across products using the same protein sources — suggesting the root cause often isn’t protein, but the broader formulation system.
In reality, heavy metals can enter through many pathways – flavor systems, mineral blends, colorant, and macro ingredients (including protein). Solving the problem, therefore, requires building transparent, traceable, end-to-end ingredient systems. PURIS has designed an ingredient system that makes clean products possible.

How Clean is Your Protein?
Protein makes up 90%, or more, of the typical nutrition powder, so the journey to clean products starts here. Not all plant proteins are created equal. Plants, including peas naturally absorb minerals from the soil including heavy metals like lead and cadmium. That’s why PURIS doesn’t just test the end product. We can actively manage heavy metals at every step:
- Field-level sourcing from low-contaminant regions
- Annual testing of raw peas and finished ingredients
- Proprietary processing that reduces lead and arsenic levels
- Batch-level data to support your compliance and marketing claims
Our most advanced programs deliver protein with lead levels as low as 0.008 ppm — well below Prop 65’s 0.025 ppm threshold for a 20g protein serving. Cadmium, arsenic, and mercury are similarly controlled. And we’re constantly improving.
Getting Questions About Lead? We’ve Got Answers.
Your customers are reading the headlines. So are regulators. From Consumer Reports to Prop 65 notices, heavy metals in protein are under the microscope and brands are being asked to prove their products are safe.
At PURIS, we’ve spent years preparing for this moment. Our vertically integrated supply chain gives us unique control over heavy metals: from the soil our peas grow in, to the protein that ends up in your product. Whether you’re formulating high protein beverages, toddler nutrition, or organic cereals, we partner with you to stay ahead of the questions and the regulations.
Will You Pass Prop 65?
California’s Prop 65 sets some of the strictest limits in the world and it’s not just about what’s in your protein. It’s about what’s in your final product. That’s why we help you start clean.
PURIS ingredients are tested to meet or exceed FDA and EU standards. And when you need to go even further — for Prop 65 and sensitive categories like toddler nutrition or premium wellness — we offer solutions that align with the tightest customer specs in the industry.
We’ll work with you to identify the right ingredient for your formulation and your risk profile.
Need the Data?
We’ve Got It.
We don’t just say our protein is clean, we prove it. PURIS routinely tests for lead, cadmium, arsenic, and mercury and has a long track record of doing so. We can provide:
- Annual monitoring through our top-notch Food Safety, Quality, and Regulatory Programs
- Certificates of Analysis for every batch
- Historical data to support your compliance documentation
- Technical support for exposure assessments and regulatory reviews
Our partners, from global brands to emerging startups, rely on PURIS to help them navigate evolving regulations and rising consumer expectations. We’re here to help you do the same.
Why Puris?
The only real way to control heavy metals in plant‑based ingredients is to control the entire supply chain. With that level of visibility and identity preservation, we can prevent contamination rather than test for it after the fact. This closed‑loop model lets PURIS deliver cleaner, more consistent plant‑based solutions and give leading health and wellness brands the confidence they can’t get from fragmented global supply chains.
