Protein powders — whey, plant-based, collagen, and egg white — routinely accumulate heavy metals from raw material sources and residual solvents from extraction and drying processes. A complete third-party COA covering metals, solvents, microbiology, and label claims is increasingly required by Amazon, major retailers, and NSF certification programs.
The Clean Label Project and multiple independent studies have found elevated lead, cadmium, and arsenic in protein powders — particularly plant-based products from pea, rice, and hemp. Testing every product lot protects your brand and satisfies retailer compliance programs.
Lead, cadmium, arsenic, and mercury accumulate in plant proteins from soil. California Prop 65 and FDA action levels set the compliance threshold.
Hexane extraction is commonly used for soy and plant protein concentrates. Residual solvent testing verifies extraction efficiency and consumer safety.
Protein powder is a nutrient-rich substrate. TAMC/TYMC and specified organism testing (Salmonella, E. coli) is required by most cGMP and retailer audits.
Protein content by Kjeldahl or amino acid analysis verifies label claims and protects against FDA and FTC scrutiny.
Amazon has removed protein supplements for Prop 65 violations. Proactive testing COA documentation is the first line of defense for marketplace sellers.
NSF Certified for Sport requires third-party analytical data. Our COA format satisfies the documentation requirements for NSF program submission.
Our standard protein powder panel includes:
