Serrapeptase is a proteolytic enzyme found in the digestive tract of the Japanese silkworm and has been used as a nutritional supplement in Europe and Asia for over three decades. 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.

Good start

I got it for my parents. My father 84 has problems with his sinuses for years. After taking it for a week his nose stopped running and no more sneezing. So far so good. My mom has arthritis and I really hope it will help. So far no change.

Thanks for your feedback!

Seems that it works

I take 2 capsules , 2 or 3 times per day . I think it helps with sinus congestion and pain, it is different when I am not using it . I recommend it

Thanks for your feedback!

Great product at an exceptional price.

This product combined with Nattokinase is one of the best ways to improve blood health problems, speaking from experience of having bi lateral pulmonary embolisms 4 times over 7 years and having to use pharmaceutical drugs (warfarin) with side effects of bleeding gums, nose and bruising. Serrapeptase has helped in removing the clots and have kept my lungs clear for over a year.

Thanks for your feedback!
