PCC replies: Thank you for your question about PCC’s bulk vegan protein powder.

We understand and share your concerns regarding the multitude of studies that regularly report heavy metal contamination in various foods and supplements. The most recent study of plant-based protein powders, from the Clean Label Project is yet another of many that add to the volume of literature supporting what we already know — that heavy metal contamination is pervasive and a global issue that needs to be addressed through the collective efforts of lawmakers, government agencies, global health authorities, manufacturers, farmers, and retailers.

The Clean Label Project report did not reveal which brands they tested, so we cannot determine whether brands PCC sells were part of the analysis. We recommend reaching out to brands directly because it is important for manufacturers to hear from the people who buy their products if they have concerns about their testing practices or quality.

PCC sets high standards and sourcing priorities for our supplement products, including protein powders. We prohibit many additives like artificial dyes and flavorings, and prioritize clean ingredient items with fewer unnecessary binders, thickeners, and flow agents. We also require products to be produced following Current Good Manufacturing Practices or have the NSF International Certification for quality. We also value third party certifications that help provide assurances to customers about the quality, ingredients, production methods, and more. PCC does not have the capacity to conduct our own independent testing of all our products.

We always encourage shoppers to choose what they feel comfortable consuming and if you have concerns regarding health impacts, we’d encourage you to talk with your physician or a nutrition specialist, especially as heavy metal contamination is a known issue in the environment and not isolated to specific products or brands.
