Overview
Doctor's Best Serrapeptase provides 120,000 SPU (serratiopeptidase units) of this proteolytic enzyme originally derived from silkworms. Serrapeptase breaks down non-living tissue including fibrin, mucus, and scar tissue. Used extensively in Europe and Japan for sinus health, joint comfort, and post-surgical recovery. The enteric-coated capsule ensures the enzyme survives stomach acid to reach the intestines where it's absorbed.
