Product overview
If you're into supporting your health using natural methods, serrapeptase is the way to go! It's one of the most potent proteolytic enzymes that has been researched. Serrapeptase is a protein-digesting enzyme isolated from the friendly bacteria Serratia E-15, which is found in the Japanese silkworm.
  • Traditionally used as a nutritional supplement in Europe and Asia for more than three decades.
  • Supports and maintains healthy sinus and airway function as well as a healthy immune response.
  • Supports the dissolution of hard particles made of protein.
Enzyme to the rescue!
Serrapeptase is a proteolytic enzyme that comes from the Serratia bacteria species strain E15 and has been studied for over 40 years. Serrapeptase has protein, mucus and fibrin-digesting properties and has been shown to support immune function. It is also known for supporting circulation, cardiovascular health as well as joint health and comfort. As serrapeptase can be destroyed by stomach acids, High Potency Serrapeptase uses Serrateric™, a coating that protects the enzyme until it reaches the intestines and therefore aids absorption.

So far so good been two weeks now, and I've gone from using 3-4 400mg ibuprophen tablets a day to one serrapeptase, I'm planning to up the dose in winter when my pain is worse. I suffer chronic backpain and have osteoarthritis now too. It's working and no side effects.


Still early days as I like to wait 3-6 months to evaluate a product such as this but early indications are it seems to be helping with my COPD
