What’s Inside Serracor-NK^®

SEBkinase^® Blend:

Serracor-NK^® is a powerful blend of acid-resistant serrapeptase (Peptizyme SP^® EN) and acid-resistant nattokinase, systemic enzymes studied for their fibrinolytic properties.* 

Enzyme & Cofactor Blend:

• Bromelain: A proteolytic enzyme found in the pineapple plant; known for immune support and its fibrinolytic activities*
• Papain: Derived from papaya; supports the body’s natural immune response.*
• Lipase: Breaks fats down into essential fatty acids that are needed to support healthy circulation and immune and healthy inflammatory responses.*
• Rutin: Bioflavonoid that provides antioxidant support.*
• Amla: A powerful natural source of Vitamin C; an antioxidant that supports immune response and healthy metabolism.*
• Coenzyme Q10: An essential enzyme and cofactor in metabolism.*
• Magnesium: An essential mineral used as a cofactor; supports cardiovascular and nerve health.*

How Serracor-NK^® Works: What is Fibrin and Why Take Fibrinolytic Enzymes

Serracor-NK^® works by supporting healthy fibrin levels in the circulatory system. Fibrin is a thread-like protein that the body produces when healing. Imagine you scrape your knee – your blood immediately clots, and your body makes a scaffolding out of fibrin 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. Although your body naturally does this with an enzyme called plasmin, plasmin levels progressively decrease as we age. This actually increases the risk for excessive, undesirable scar tissue formation in the body.

Fibrinolytic enzymes are proteases that break down the tough strings of fibrin protein. Serracor-NK^® is a powerful blend of acid-resistant serrapeptase and acid-resistant nattokinase with synergistic enzymes, antioxidants, coenzyme Q10 and magnesium. Serrapeptase and nattokinase are two systemic enzymes studied for their fibrinolytic properties.*

This complete array of proteolytic enzymes, herbs, and minerals supports healthy circulatory and respiratory systems and healthy fibrin metabolism.*

How MAAC Acid-Resistant Polymer Makes Serracor-NK^® Uniquely Effective

Your stomach is naturally acidic to help digest food. But not every supplement can tolerate that acidity. Some enzymes, like serrapeptase and nattokinase are powerful but delicate. They need a special delivery system that helps protect them from stomach acid. The cutting-edge, phthalate-free, methyacrylic acid copolymer (MAAC) applied to the serrapeptase and nattokinase in Serracor-NK^® 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, the MAAC-containing enzymes used in Serracor-NK^® were found to have enzyme activity significantly greater than those without MAAC after passing through the acidic conditions of the stomach, allowing for much 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 serrapeptase and acid-resistant nattokinase because they deliver the best enzymes in their best form.*
