What's the right amount of serrapeptase to take every day? Some manufacturers don't make it easy to figure out how much serratiopeptidase is actually in a product. The medical literature usually refers to “SU,” or serratiopeptidase units. This is a measure of how much fibrin protein a unit of the problem can break down. And some of the best manufacturers measure the products in “IU,” or international units. These units are difficult to translate into milligrams, because enzymes are measured by the amount of work they do, not their mass.
The very lowest dose of serratiopeptidase that will usually get a response in children is about 10,000 IU. The very lowest dose that will usually get a response in adults is about 20,000 IU. Some products offer about 40,000 IU, while the best brands usually contain about 80,000 IU in every pill. It all gets a little confusing. But if you go with brands you trust (click here to see the serrapeptase products I trust – I have used serrapeptase products from this manufacturer for years), you can just make sure you take one dose a day rather than worrying about milligrams, SU, or IU. Don't take more than the manufacturer recommends.
I recommend that you either use enteric-coated serrapeptase (serratiopeptidase) products; the enteric coating keeps the enzyme from being destroyed by acid in the stomach so it arrives intact in the small intestine to be absorbed into the bloodstream.
And never leave serratiopeptidase in your car on a summer day. The interiors of cars heat quickly, and just 15 minutes at 55° C (132° F) will ruin the product.
