Activity
Is enzyme activity stated in SPU per capsule, with serving size and ingredient weight clearly separated?
Serrapeptase Comparison Guide
Comparing Serrapeptase? Look Beyond the Front-Label SPU.
When products lead with different SPU numbers, use the same four questions for each one: What activity is declared per capsule? How is delayed release built? What was tested on the finished dosage form? Can the evidence be traced to the bottle lot?
Activity · Delivery · Finished-Product Testing · Traceability
Same questions. Same standard. Then compare the evidence.
Use the Same Standard
Four criteria make serrapeptase claims easier to compare.
The goal is not to chase the largest number. It is to understand what the number means, how the dosage form is built, what was tested on the finished product, and how much evidence is actually inspectable.
2
Delivery
Does the product explain its delayed-release architecture, rather than relying on a vague protection statement?
3
Finished Product
Is there testing on the finished dosage form that documents gastric resistance and intestinal-phase disintegration?
4
Traceability
Can the bottle lot be connected to results, methods, test dates, and available source documentation?
Separate Architecture from Testing
What is built and what is measured are different questions.
A delivery-system name should describe the dosage-form design. A finished-product test should document how the completed dosage form behaved under the stated method. Those are related, but they are not interchangeable.
Bilamex™ describes the delivery architecture.
Bilamex™ is iSerra's two-stage physical delayed-release design. It describes how the dosage form is built, not a test result or a promised health outcome.
- Stage 1: delayed-release capsule.
- Stage 2: coated enzyme-containing particles.
- Architecture is disclosed separately from finished-product testing.
USP <2040> documents finished-product behavior.
Finished-dosage-form disintegration testing is reported separately so a buyer can distinguish the formulation architecture from measured gastric-resistance and intestinal-phase disintegration performance.
- Finished-product method is identified.
- Lot-specific status is reported when available.
- The result is a dosage-form test, not a clinical efficacy study.
Now Apply the Framework to iSerra
Here is what iSerra discloses for each criterion.
Apply the same four criteria to any serrapeptase label. The right column shows the disclosures iSerra provides for each category.
| Criterion | What to inspect | iSerra disclosure |
|---|---|---|
| Activity | SPU per capsule, serving size, ingredient weight, and whether a lot-specific measured activity result is available. | 250,000 SPU declared per capsule; current shipping lot 6798 reports 292,327 SPU measured activity. |
| Delivery | The physical dosage-form architecture used to delay release through the gastric phase. | Bilamex™ Dual-Phase Delivery: delayed-release capsule + coated enzyme-containing particles. |
| Finished-product testing | Testing performed on the finished dosage form, with the method identified. | USP <2040> disintegration testing is identified; current lot status: Pass — USP <2040>. |
| Traceability | A lot-specific record tied to the bottle, including methods, dates, results, and supporting records when available. | Veriphase™ Lot Verification connects a production lot to the available verification record and supporting source documentation when available. |
Lot-Specific Evidence
See what lot-specific evidence looks like in practice.
Production lots change. The lot printed on the bottle is the authoritative lookup key. The current shipping lot is shown for context, and a specific bottle can be checked by its own lot number.

Comparison Questions
Know what the evidence can—and cannot—tell you.
Is a higher milligram amount the same as higher serrapeptase activity?
No. Milligrams describe ingredient weight; SPU describes enzyme activity. Compare the stated activity units and serving size rather than using weight alone as a proxy for potency.
Does a measured lot result replace the 250,000 SPU label claim?
No. 250,000 SPU per capsule is the declared specification. A measured activity result belongs to a specific production lot and can vary from one lot to another.
What is Bilamex™ Dual-Phase Delivery?
Bilamex™ describes the physical dosage-form architecture: a delayed-release capsule surrounding coated enzyme-containing particles. It is separate from finished-product disintegration testing.
What does USP <2040> testing show?
It is finished-product disintegration testing used here to document the dosage form's gastric resistance and intestinal-phase disintegration behavior. It does not establish a clinical outcome.
Can I verify the lot on my own bottle?
Yes. Enter the production lot printed on your bottle on the Verify Your Lot page to access the applicable available record.
