Serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the individual enzyme until it reaches the intestine for optimal absorption.

Suggested Use

Adult Use: Take 1 capsule up to 3 times daily without food, or as recommended by a nutritionally-informed physician.

Other Ingredients

Cellulose, serrateric, modified cellulose (vegetarian capsule).


Store in a cool dry place.

Definite Improvements

Posted by iHerb Customer on Oct 09, 2017 | Verified Purchase

My herbalist recommended this supplement as I have constant hay fever, sinus infections and a cold that never seems to go away...or at least I had! I started taking these in April. I didn't really notice a difference until around June / July. This summer my sinuses dried up. I barely noticed any hay fever, have not had any problems with my sinuses since taking them and am like a different person. I no longer need to keep blowing my nose! I was taking 3 a day so recently just changed to the high potency. I believe there are many other health benefits to this enzyme. It is said to heal scar tissue, help with inflammation, aid digestion. I take it first thing in the morning.

Thanks for your feedback!
