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. It's alll been said-it's the best.


    When I don’t pay attention and have to go to the health food store to get a bridge product until my Serracor arrives in the mail, I immediately feel the difference on the first day of being without. As soon my Serracor arrives and i take that first dose when I haven’t had it for a day or two-there is an immediate energetic shift and a cooling sensation occurs in the first hour. I don’t know what this is but it’s a welcome sign to me. It’s says it’s working.

  2. Great results on uterine fibroids


    Using this product and changing my diet (along with SerraRX and Dimpro) has reduced the size of my very large uterine fibroids by 6 inches so far. These are great products.

  3. Only Read If You Want to Feel Better

    Susan H

    I had recently had surgery on my shoulder which resulted in a lot of medication for about 9 weeks after. Pain meds, antibiotics, steroids, sleeping pills etc. By the time I had recuperated, my insides felt so congested from all the prescription drugs. I started breaking out in random rashes and just felt terrible. That is when I started taking Serracor, Floricor and Vida Defense. I am now off all of those meds and feel like a different person. You have to give them a little time to start working and to feel the difference but there is a difference and that is the important part. Follow the recommended amounts that they send in the brochures that accompany the product and you will be well on your way to feeling healthy and in control of your body.

  4. Supplements that work.


    This product is great. It digests easy.

  5. Reduced Muscle Aches

    Ken Sharpe

    Since taking Serracor NK I have far fewer incidents of trigger points causing me tendinitis & other muscle pain.

  6. If I could hug you through my computer I would!

    Diane C

    I have been using Serra RX and Serracor NK for several months. I have had severe eye swelling due to lymph removal in my neck. I was diagnosed with Lymphedema. I have been through Hodgkins Disease and Breast cancer. I have been to countless doctors and none of them knew what to do. I have spent hundreds of dollars trying everything that claimed to help. Nothing worked. I was researching on-line and stumbled upon your website I called and asked a lot of questions. I thought why not give it a try I’ve already spent a ton of money. After 4 weeks I started to notice the swelling was less. After 2 months it is so small that my friends and family can’t notice it anymore. The pain and swelling are nearly gone. I have literally cried with relief. I did a lot of research about the product and I have found nothing but positive responses. If I could hug you through my computer I would. I swear this is the truth. Please try these products. I know people say this but truthfully this is the first product review I have ever written. I intend to use these products forever.

  7. Excellent products!

    Robert B

    Excellent products! After 24 months of using Serracor-NK and Serra Rx my IPF has remained stable!! My respiratory specialist thinks I should have been dead about 21 months ago, he’s a bit upset.

    Have also started using Prostate Rx 14 which has reduced my PSA reading from 12.25 to 9.49 in 3 months

  8. seems to work...


    have not quit useing —so i guess its working

  9. I've regained my stability


    I was diagonised with extramural fibroids in 2006 , I’ve been having pressure in my body that was giving me headache especially if I wear a trousers or skirt that is tight on my waist , I was really feeling uncomfortable , weak and unstable, was having blotted stomach. I started taking Serracor-NK and Serra RX now 6 weeks , I’m feeling strong, the pressure has gone I can wear tight trousers, I can exercise, I’m feeling stable and strong, my last month period was very heavy with big clots. I’m going to have a MRI scan next week I hope the size will be reduced.

  10. I feel like a new man
