Our Testing Standards
Every Ketosource product is tested by independent ISO 17025 accredited laboratories across three categories. Results are published for every batch - no exceptions.
How the Quality Score Works
Each batch receives a score out of 100, calculated from three independent testing categories. The weighting reflects the relative impact on product quality and consumer safety.
Active Ingredient Purity
Verifies the actual amount of active ingredients matches what is on the label. We test every batch against label claims.
Heavy Metal Analysis
Tests for lead, cadmium, arsenic, and mercury. Results benchmarked against Prop 65 (California) and EU EFSA limits.
Microbial Safety
Screens for bacteria, yeast, mold, E. coli, and salmonella. Every batch must pass before shipping.
Allergen Transparency
Clear labelling of what each product contains, is free from, and may contain. No hidden ingredients.
