Understanding Fibrin

Fibrin is an insoluble protein the body produces in response to bleeding or inflammation. Fibrin performs important functions in the body, including clotting and wound healing. During the blood clotting process, the protein precursor fibrinogen is converted into fibrin, which forms a layer of connective tissue inside the damaged blood vessel. To do this, the fibrin strands assemble into a net-like structure over the damaged vessel and harden, forming a "patch" or small clot to prevent further damage.

Despite its protective function, excessive fibrin can do more harm than good. A high level of circulating fibrin has the potential to accelerate scarring, increase clot formation and impede normal blood flow. This can lead to increased blood viscosity, swelling, edema, pain, chronic inflammation and more serious fibrotic conditions or cardiovascular events.

According to Scripps Research Institute, "It is generally assumed that the persistence of fibrin in the extra cellular matrix (connective tissue) promotes fibrosis, and that the extent of fibrosis is limited by proteases (protein-digesting enzymes) that remove the fibrin. Fibrotic disease occurs when normal control of this process is compromised and excess fibrous material accumulates in the tissues."

The proteases in Serracor-NK® support normal fibrin levels, blood viscosity, overall blood circulation and healthy inflammation responses.*

Serracor-NK for Circulatory & Inflammation Support

Serracor-NK contains SEBkinase® with enteric coated serrapeptase and nattokinase. 

SEBkinase brings together two enteric coated, fibrinolytic proteases: Peptizyme-SP® (Serrapeptase) and NattoSEB® (our Nattokinase is Vitamin K-free, since it assists in blood coagulation). Serracor NK further supports the activity of SEBkinase-CV with a complete array of proteolytic enzymes, amylase, lipase, CoQ10, herbs and minerals. The net result is a comprehensive systemic enzyme blend designed to support maximum circulatory health.*

Serracor-NK also promotes healthy levels of C-reactive protein (CRP), an inflammation marker and serious risk factor for inflammation and cardiovascular disease.* In addition, the entire systemic enzyme blend is manufactured in a ISO 9001:2000 and GMP certified facilities using our Bioactive Protein Peptide System® (BPPS).

  1. works better than steroids 5 Star Review

    Posted by on 5th May 2019

    My husband had an injury to his eye and the docs put him on steroids to try and get rid of swelling. But the side effects were not good. As soon as he would try and reduce the steroids, his eye would start to swell up again, so back to the steroids... not good.
    In desperation, I took matters into my own hands and did quite a bit of research and found this product. It worked ! I got my husband off steroids, and, along with other supplements, got his eye healed, and away from the dangerous meds. Thank you so much for this product!!

  2. I can't believe this exists! 5 Star Review

    Posted by on 7th Oct 2018

    I have been struggling with Psoriatic arthritis among other issues for over 13 years. I have lung nodules and decrease in o2 sats. I was having infusions every 8 weeks, which made my immune system so low, I would catch every sickness. I decided to come off of everything and try Serracor-NK and Serra Rx 260 2 months ago. It took about 2 weeks to fully feel the effects. I breath much better, my scar tissue is decreasing from all the surgeries I have had and most of all I am in minimal pain throughout the day where I only need to supplement with one pain med. This is amazing , I am ordering moreand going to try other products as well! Thank you Thankyou

  4. Great product 5 Star Review

    Posted by on 25th Nov 2017

    I take these to thin my blood to help reduce my blood pressure. I never knew until recently that blood viscosity is a big factor in high blood pressure. They are working, and as a by-product make you feel good too! These enzymes work on so many different issues as a little research will show.

  5. very happy with this product 5 Star Review

    Posted by on 21st Sep 2017

    This product has helped me with uterine fibroids and has also helped me maintain a healthy blood pressure. I am over 50 and pleased to say I do not take any prescription medications!! These are part of my healthy routine daily.

  6. Great help 5 Star Review

    My husband, Jerry, has been diagnosed with Pulmonary Fibrosis and has received great help with this product!!

  7. Breathing is Better 5 Star Review

    Posted by on 15th May 2017

    After taking this product along with Serra RX260 for only 3 weeks, my father's breathing is so much better and he is not coughing much at all. Before my father started taking these products, he had become so weak and tired from coughing so much and his breathing very labored due to pulmonary fibrosis. His breathing is so much better now and he is happy because he can stand up taking a shower rather than sitting down a lot and breathing so hard. These products are a Godsend to my father.

  8. Serracor has removed that plaque and there is no more murmur. 5 Star Review

    Posted by on 21st Apr 2017

    I am currently taking 4 caps of Serracor 2X per day as recommended on the bottle.
    I have some arthritis that I think this helps with, but still deal with some pain.
    I had a calcium score test that showed a mild plaque buildup of 51.66 Total Agatston Score which is less than 25% rank of all people my age group. That test was run 9/18/2015. Of particular interest, when I saw my Cardiologist and Primary care physician the first of this year, neither of them could detect a heart murmur I have had for a number of years. In many cases, a murmur is due to plaque build up on the valve flapper. So, I can believe that the Serracor has removed that plaque and there is no more murmur.

  9. Reducing Keloid Scar and Abdominal Adhesions 5 Star Review

    Posted by on 27th Feb 2017

    I have been using Serracor NK with Serra Rx 260 for 7 weeks. I am taking it to reduce the appearance of my external scar which keloid and abdominal adhesions from 4 repeat C-Sections. My external scar has keloid quite a bit after each baby. During my last two C-Sections, the dr discovered abdominal adhesions which affected my uterus and bladder. I did some research on options to reduce and possibly eliminate the scaring and came across this product. I decided to try it since it seemed like a generally risk free option as opposed to surgery. I started taking 3 Serracor NK morning, noon and night with 2 SerraRx morning and night. After 2-3 weeks I noticed very slight changes to my external scar so I decided to add another SerraRx to my afternoon dose. Within 1 week of taking that extra one I noticed it was changing more rapidly. Now my scar is lighter in color, thinner, flatter and smoother. It has worked from the ends of the scar in as far as thinning it. So far I have been extremely happy with this product and the results. I will continue taking them until my external scar seems to be minimal and then I will look into seeing what it has done internally. With no noticeable negative side effects, I would definitely recommend giving this product a try if you are in a similar situation with scarring.

  10. Diminishing scar tissue and fibrin 5 Star Review

    Posted by on 25th Feb 2017

    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.

    Posted by on 18th Aug 2016

    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.

  16. So very good for the heart 5 Star Review

    Posted by on 7th Dec 2015

    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.

  17. It was God sent.. 5 Star Review

    Posted by on 8th Sep 2015

    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 ..

  19. Pulmonary Fibrosis Package 4 Star Review

    Posted by on 12th May 2015

    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

  20. It's alll been said-it's the best. 5 Star Review

    Posted by on 30th Dec 2014

    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.
