What We Test For
- Identity & Potency: Confirms the exact amount of Berberine HCL per capsule matches our label claim.
- Heavy Metals: Lead, arsenic, cadmium, and mercury tested to USP <232> standards.
- Microbial Limits: Total aerobic count, yeast, mold, E. coli, and Salmonella per USP <2021>.
- Purity: No undeclared ingredients, fillers, or contaminants.
Why 77% Concentration?
Each capsule weighs approximately 780mg total. Of that, 600mg is pure Berberine HCL (the active ingredient). The remaining ~180mg consists of the vegan cellulose capsule shell and trace flow agents required for manufacturing. This means 77% of each capsule by weight is the active compound — a higher concentration than many competitors who use significant filler ratios. See Funk et al., 2018 on potency variability (PMID: 29325474).
