The Difference

What to Compare When Choosing Serrapeptase

What to CompareiSerra™What to Look For
Declared & Measured Activity250,000 SPU (130 mg) declared; each lot assayed for actual measured activity.Is that SPU figure per capsule—or per multi-capsule dose? Does the documentation report measured activity, not just declared weight?
Delivery ArchitectureBilamex™ Dual-Phase Delivery — delayed-release capsule + coated particles.Does the label explain how the enzyme is protected through digestion?
Lot-Specific DocumentationCOA lookup by production lot.Can you inspect testing tied to the lot on your bottle?
Independent Testing & AccessIndependent third-party laboratory testing; original COA available through Veriphase™.Is testing independent, and can you view the underlying document—not just a summary?
Identity ConfirmationIdentity confirmed through the USP proteolytic assay used to measure enzyme activity.Does the documentation confirm identity, not just activity?
