Premium Systemic Enzyme Formula | Circulatory and Respiratory Support

  • Heart and Circulatory Health*
  • Respiratory Health*
  • Fibrin Metabolism*
  • Normal Blood Viscosity*
  • Healthy Blood Pressure*
  • Healthy Response to Inflammation*



Serracor-NK is a carefully formulated, comprehensive systemic enzyme blend designed to support maximum circulatory, respiratory and fibrotic health. Serracor-NK contains the dual-action formula SEBkinase®, a combination of two potent fibrinolytic enzymes which have powerful synergistic effects.  A carefully selected palette of additional enzymes, herbs and minerals enhance SEBkinase to create a highly effective new formula.

Why Take Fibrinolytic Enzymes?

Fibrin is important. Your body naturally produces fibrin in response to injury or trauma.  Imagine you scrape your knee – your body immediately produces a clot and a thread-like protein called fibrin forms a structure in that clot to hold it in place.  This acts as a natural bandage as the body heals.  Like that scab on your knee, your body uses fibrin to repair internal injuries as well.

But too much fibrin can do more harm than good. It can accelerate scarring, leading to chronic inflammation, pain, and unsightly blemishes.  More seriously, excess fibrin can increase clot formation and impede normal blood flow, which can lead to more serious fibrotic conditions or cardiovascular events.

Maintaining healthy fibrin metabolism is essential.  Serracor-NK supports normal fibrin levels, blood viscosity, overall blood circulation and a healthy inflammation response.*

How Enteric Coating Makes Serracor-NK Uniquely Effective

Our enteric coated Peptizyme SP® EN makes Serracor-NK unique. If serrapeptase is not enteric coated, the acidic environment of the stomach will destroy its potency. Other companies do not have enteric coated serrapeptase. They try and make up for it by selling higher and higher potencies, which ultimately still do not work.  Our cutting-edge enteric coating maximizes serrapeptase potency through the stomach and delivers it into the small intestine, where it is most needed.*

What’s In Serracor-NK?

  • Peptizyme SP® EN (the enteric coated serrapeptase in SEBkinase): known for its beneficial immune cell response. It was first found in silkworms, which used serrapeptase to dissolve their tough fibrous cocoons.
  • NattoSEB® (the nattokinase in SEBkinase): the active ingredient in an old Japanese folk remedy for cardiovascular support.
  • Bromelain and Papain, known for their immune support properties
  • Lipase to break down fats into essential fatty acids needed for healthy circulation
  • Rutin for antioxidant support
  • Amla a strong source of Vitamin C
  • CoQ10 as a cofactor in metabolism, and
  • Magnesium to boost SEBkinase performance and support cardiovascular and nerve health.*

  1. Diminishing scar tissue and fibrin

    Lynn B

    I have a superficial blood clot on my hand, I was on clexane injections everyday for 3 months after which doctors and surgeons have said nothing can be done about it , my naturopath suggested using Serracor 12 tablets a day , and it’s slowly working , along with other non related scar tissue diminishing as an added bonus in the process .
    Thank you
    My only small gripe is that it is not readily available in Perth Australia and I have to order from US.

  2. scar tissue help


    This product is helpful to soften internal scars that did not respond to manual stretching

  3. this works for me


    I started taking this for my uterine fibroid and suffered from heavy bleeding and pain. I have no more pain or swelling and my bleeding is significantly less. This also helps keeping my blood pressure at a perfect number!

  4. good product


    Since I have been taking these products, I have really been experiencing better breathing. I will continue with these products for as long as I live because I now know the importance of enzymes in my life.

  5. It really helps!


    We are Very Happy with this Product! We Highly Recommend this Product.

  6. I can breat again


    I have been using Serracor NK for 3 months for Pulmonary Fibrosis. Since then I have regained my ability to breath again. I feel energized because the phlegm and crackles in my lungs have reduced. I am walking again, slowly but much more than before. I only take Serracor NK and have attributed my progress to the product. This has been a true blessing for me, my lungs and my family.

  7. So very good for the heart

    G. G.

    I have a heart that skips, or pauses, and then races ahead. Some times it beats very fast. Sometimes very slow. I suppose I’m a good candidate for a pace maker but I dont want one if I can help it. My heart LIVES Serracor. Serracor keeps my heart beating at a regular normal pace, blood pressure is good. If I forget to take the Serracor my heart reminds me within a day. I am so gratefull this product is available.

  8. It was God sent..


    I had no insurance and as a Christian I didn’t know what to do . I had 12 fibroids. I had trouble breathing, taking walked and being active it was hard for me . I couldn’t get my right arm above my head to zip a dress and I kept praying and being a person that believes in natural things. I kept seeing Dimpro RX and the Serracor-NK and I said Lord I don’t know but show me and he told me to get it. With three days I could get up a hill , ,my arm lifted and the fibroids are shrinking everyday. I rest there is no pain.For me this was an answer and clearly directed. ASK God he will show you .. and thank you for this product. Its been God sent to me.. Reasonable cheaper then an Ultra sound .which I had and I can exerciase. enjoy walks again and be active. it works. ASK GOD ..

  9. It really helps!

    I recommend it highly.

  10. Pulmonary Fibrosis Package


    My husband has been taking the Pulmonary Fibrosis bundle since he was diagnosed with the disease in Sept 2011. He has had a C-scan every year since his diagnosis and Thank God there has been no change. His lung specialist told him to keep doing whatever he’s been doing because it’s working. Prayer, the pulmonary bundle and walking daily has been his routine. We stunbled upon these products after his being diagnosed while surfing the net for information to understand the dreadful disease. and Thank God for it. We are doing all we know to do in the natural and trust God with the outcome. Thank you
