Frequently Asked Questions
What is iSerra™?
iSerra™ is a high-activity serrapeptase supplement providing 250,000 SPU per capsule. It uses Bilamex™ Dual-Phase Delivery and Valispec™ lot-specific verification.
What does 250,000 SPU mean?
SPU is an activity unit used for serrapeptase. iSerra declares 250,000 SPU per capsule. Activity is different from ingredient weight, so compare enzyme products by declared activity as well as capsule contents.
What is Bilamex™?
Bilamex™ is iSerra's Dual-Phase Delivery architecture: a delayed-release capsule combined with coated particles. The finished product is evaluated for disintegration performance.
What does USP <2040> testing refer to?
It refers to finished-product disintegration testing. It describes how the dosage form performs under the test conditions; it is not a clinical-outcome claim.
How do I verify my bottle?
Enter the lot number printed on your bottle on the Verify Your Lot page. Valispec™ displays the information available for that production lot.
How should I take iSerra?
Follow the suggested-use directions printed on your current bottle. If you are pregnant, nursing, taking medication, taking blood thinners, or preparing for surgery, consult a healthcare professional before use.
