Enzyme to the rescue.

Serrapeptase has been used as a nutritional supplement in Europe and Asia for more than three decades. Known to promote healthy sinuses and airway function, it is a protein-digesting enzyme isolated from the friendly bacteria Serratia E-15, which is found in the Japanese silkworm.* A worm? Yes, a worm.

We chose Serrateric™ for this formula because it protects the individual enzyme until it reaches the intestine—this allows us to more efficiently absorb the nutrient.* Breathe a little easier with Doctor’s Best Serrapeptase.*
