Product Description

Serrapeptase: Acid-Resistant Serrapeptase (Peptizyme SP® EN)
Serrapeptase is a powerful systemic enzyme supporting respiratory and sinus health. Serrapeptase contains Peptizyme SP® EN‚ which is resistant to the acidic conditions of the stomach‚ maximizing efficacy.

Why Take AST Enzymes’ Serrapeptase
Serrapeptase supports healthy respiratory and sinus function‚ as well as muscle‚ joint and overall tissue health.*

The ingredient in this powerful systemic enzyme supports:

• Healthy Respiratory System
• Sinus Health
• Muscle‚ Joint and Tissue Health
• Healthy Oxygen Levels
• Muscle Recovery

What’s Inside Serrapeptase
Acid-Resistant Serrapeptase (Peptizyme SP® EN)

What is Serrapeptase?
Serrapeptase—also known as serratiopeptidase—is an enzyme belonging to the serine protease class. As a protease‚ it breaks down proteins into smaller components called amino acids. Serrapeptase was originally discovered in the digestive tract of silkworms in the 1960s. It is often called the “butterfly enzyme” because its strong fibrinolytic activity enabled the silkworm to dissolve its tough‚ fibrous cocoon when it was ready to emerge. This same fibrinolytic activity was identified to support human cardiovascular and inflammatory systems and has been consumed by humans for decades.

Serrapeptase is a concentrated natural proteolytic enzyme supplement. But AST Enzymes don’t use just any serrapeptase. Their ingredient‚ Peptizyme SP® EN‚ is specially formulated with an acid-resistant polymer which helps protect the delicate enzyme from the acidic conditions of the stomach‚ allowing delivery of significantly more activity to the small intestine‚ maximizing efficacy.*

Why Take Fibrinolytic Enzymes?
Imagine you scrape your knee – your blood immediately clots‚ and your body makes a scaffolding out of fibrin (a thread-like protein) to hold the clot in place. This acts as a natural bandage as the body heals. Your body uses fibrin to repair internal injuries too.

But your body also has to take down the fibrin scaffolding (a process called fibrinolysis). Your body naturally does this with an enzyme called plasmin‚ which breaks down the fibrin into parts the body can process. Healthy fibrinolysis is critical to manage pain‚ scarring and potential blood clots.

Fibrinolytic enzymes are proteases that break down the tough strings of fibrin protein. Supplementing with fibrinolytic enzymes can help your body maintain healthy fibrin metabolism.

Why Choose AST Enzymes’ Serrapeptase
AST Enzymes’ Serrapeptase is the strongest in the world‚ unrivaled among products of its kind because it is packed with 130‚000 SPU per capsule of this specially formulated Serrapeptase with an acid-resistant polymer to maximize its effectiveness (80K is also available). It is manufactured in ISO 9001:2000 and NSF GMP certified facilities and undergoes rigorous quality testing.

How MAAC Acid-Resistant Polymer Makes AST Enzymes’ Serrapeptase Uniquely Effective
Your stomach is naturally acidic to help digest food. But not every supplement can tolerate that acidity. Some enzymes‚ like serrapeptase‚ are powerful but delicate. They need a special delivery system that helps protect them from stomach acid. The cutting-edge‚ pthalate-free‚ methyacrylic acid copolymer (MAAC) applied to this product increases potency by allowing more enzyme activity to pass through the stomach‚ delivering it into the small intestine‚ where it is most needed.

When evaluated by an independent third-party laboratory‚ AST’s MAAC-containing Serrapeptase was found to have enzyme activity significantly greater than regular serrapeptase after passing through the acidic conditions of the stomach‚ allowing for much greater efficacy.

MAAC is a food-grade compound that has been in use as an enteric coating in the pharmaceutical industry for over 50 years with no reported side effects. In fact‚ the European Food Safety Authority – an organization that conducted studies which led to the ban of six types of phthalates in personal care products in Europe in 2004 – has deemed MAAC safe for use as a coating agent in food supplements.

As a science-first company‚ AST Enzymes uses acid-resistant Peptizyme SP® EN because it delivers the best enzymes in their best form.

What Isn’t Inside AST’s Serrapeptase
Serrapeptase is free of pesticides‚ chemicals‚ preservatives‚ animal derivatives‚ dairy‚ yeast‚ fish or shellfish‚ peanuts‚ and tree nuts. All individual enzymes are kosher-certified ingredients‚ and suitable for vegetarians and vegans.

Serrapeptase is manufactured in the USA in NSF-certified facilities that follow cGMP guidelines‚ for the highest quality products.
