AST Enzymes’ parent company, Specialty Enzymes & Biotechnologies (SEB), is a major international manufacturer of enzymes for more than 20 industries. Vic Rathi, president and founder of SEB, formulated the original Neprinol® for Arthur Andrew Medical (AAM), an enzyme marketing company. It is now available from AST Enzymes as Serracor-NK. The proprietary formula for this product remains the intellectual property of SEB and has remained unchanged. The SEBkinase in Serracor-NK is the same as the SEBkinase in the original formulation of Neprinol. Only the name has been changed.

Unlike other marketing companies who purchase their blends from other sources, we are a true manufacture. One that formulates and creates enzyme supplements, not simply encapsulates and bottles them. This allows us to control every aspect of the enzymes we create and ensure that the upmost quality and potency of our enzymes are far superior all the way to the completion. Being an actual enzyme manufacture also allows us to perform quality control tests on the enzymes to guarantee the quality is second to none and consistently the same product.

There are several systemic enzyme products on the market today. In this case, there are two alternatives: an enzyme product from an expert manufacturer or one from a marketing company. You deserve the highest quality and most effective enzyme products available. We encourage you to make an informed choice.

Enteric Coated Serrapeptase and Nattokinase: Why is it important?

 Most nattokinase and serrapeptase brands on the market are not enteric coated, which means, they can lose a significant portion of their fibrinolytic activity and effectiveness in the acidic environment of the stomach. The enteric coating of our Serracor-NK blend allows these sensitive enzymes to survive the acidic conditions of the stomach, thus allowing them to pass into the circulatory system maintaining high activity levels.

 When we design a systemic enzyme blend for human consumption, we ensure that it will tolerate the acidic environment of our gastrointestinal system. We have successfully tested enteric-coating for nattokinase and serrapeptase in Serracor-NK. Because we are the actual manufacturer of our enzymes, we test them for both pH and temperature stability.  With this experience and expertise, our entire line of enteric-coated enzymes are able to reach the small intestine with higher activity for full systemic enzyme therapy.

How do Fibrinolytic Units (FU’s) relate to enteric coating?

Enzyme activity measured in fibrinolytic units does not mean anything if the enzymes are destroyed and/or denatured in the high acidic conditions of the stomach.  Under these conditions, our laboratory tests have consistently shown that serrapeptase and nattokinase lose significant activity when exposed to low pH (such as those in the stomach).  In contrast, our enteric coated nattokinase and serrapeptase (the original SEBkinase formula) perform at greater activity levels in the same low pH conditions.

Serracor-NK for Circulatory  Support*

Serracor-NK is a powerful blend of enteric-coated serrapeptase and nattokinase, systemic enzymes studied for their fibrinolytic properties. This blend works synergistically with an additional dose of antioxidant herbs, CoEnzyme Q10 and magnesium. Serracor-NK supports a healthy circulatory system and normal fibrin metabolism.*

Key Ingredients in Serracor-NK

  • Enteric-Coated Nattokinase: A powerful fibrinolytic agent, known to support circulatory health.*
  • Enteric-Coated Serrapeptase: known to support the body in fibrinolytic breakdown.*
  • Bromelain: Proteolytic enzyme found in the pineapple plant; known for digestion and immune support.*
  • Papain: Derived from papaya, supports protein digestion and the body’s natural immune response.*
  • Lipase: Supports the break-down of fats into essential fatty acids that are needed for healthy circulation.*
  • Rutin: Bioflavonoid that provides antioxidant support.*
  • Amla: Natural source of Vitamin C, supports regulatory immune response.*
  • COENZYME Q10: An essential enzyme and cofactor in metabolism.*
  • Magnesium: An essential mineral used as a cofactor; support cardiovascular and nerve health.*

Serracor-NK contains powerful systemic enzymes formulated to support a healthy cardiovascular system, and normal respiratory function.* Serrapeptase and nattokinase both specifically address fibrin levels in the body. Serracor-NK is commonly used to support a healthy circulation*. Our blends of systemic enzymes give our customers the chance to improve their overall health without unwanted side effects.

In addition, the entire systemic enzyme blend is manufactured in a ISO 9001:2000 and GMP certified facility.
