You're getting 100,000 SPU of **Serrapeptase** per capsule — comfortably within the 40,000–120,000 SPU range used in clinical trials studying post-surgical swelling and sinus support. That said, the evidence behind serrapeptase is still limited: most studies are small and older, and a systematic review concluded the data is insufficient to fully endorse it as a supplement. Your results may vary.
The formula also includes **Protease Thera-blend** at 80,000 HUT, a protein-digesting enzyme blend that exceeds the studied range for supporting amino acid absorption. The trace amounts of calcium and magnesium are from the citrate carriers — not therapeutic doses, just part of the delivery system.
The capsule is vegetarian and designed to be taken on an empty stomach, which matters for proteolytic enzymes like serrapeptase — food in your stomach can redirect the enzyme toward digestion rather than systemic absorption.
