About AST Enzymes

AST Enzymes is a research-driven enzyme and probiotic manufacturer, and one of the largest serrapeptase producers in the world — sourcing its serrapeptase from its own fermentation facilities. A defining feature of the range is its delivery: an acid-resistant coating (Peptizyme SP®) protects the enzymes through stomach acid so they're released intact in the small intestine, where they're absorbed.

What AST Enzymes is known for

• Systemic (proteolytic) enzymes — serrapeptase, the fibrinolytic "butterfly enzyme," taken away from food and traditionally used to support a healthy inflammatory response.
• Digestive enzymes — supporting the breakdown and absorption of food. See Digestion & Gut Health.
• Acid-resistant delivery — protecting enzyme activity through the stomach.

Who it's for

Those supporting digestion, or using systemic enzymes as part of a practitioner-guided approach.
