Serrapeptase (serratio-peptidase) is a protein-digesting enzyme isolated from the friendly bacterium Serratia E-15 discovered in the Japanese silkworm. Doctor's Best High Potency 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 daily away from food, or as recommended by a nutritionally-informed physician.

Other Ingredients

Cellulose, serrateric, modified cellulose (vegetarian capsule).


Store in a cool dry place.

Huge Improvements to My Sinuses

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 x 40,000 SPU a day so recently just changed to the high potency. It is more cost efficient. 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!

Excellent product

I found I was suffering from plantar fasciitis in my left foot. On recommendations from web reviews, I decided to try this product, and can honestly say, that within 5 days, the pain and symptoms had all but disappeared. I will certainly be continuing with using this

Thanks for your feedback!
