Spotlight on an Ingredient: SEBkinase®

Spotlight on an Ingredient: SEBkinase®

SEBkinase contains two potent fibrinolytic enzymes with powerful synergistic effects: serrapeptase and nattokinase. 

Serrapeptase is an enzyme belonging to the serine protease class.  It was originally found in silkworms. When the silkmoth was ready to emerge from its cocoon, serrapeptase enabled the silkworm to dissolve the tough, fibrous cocoon. This fibrinolytic activity in serrapeptase was identified by humans as beneficial to support the human cardiovascular and inflammatory systems and has been consumed by humans for decades.

Nattokinase is also an enzyme belonging to the serine protease class, similar to serrapeptase in many ways. It was originally found in natto, a Japanese fermented soybean breakfast dish and traditionally used to support heart health, to relieve fatigue, and to support thinner blood.*

Why Take Fibrinolytic Enzymes?

Imagine you scrape your knee – your blood immediately clots and your body makes a scaffolding out of fibrin (a thread-like protein) 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. Healthy fibrinolysis is critical for managing pain, scarring and potential blood clots.

Fibrinolytic enzymes are proteases that break down the tough strings of fibrin protein. Supplementing with fibrinolytic enzymes can help your body maintain healthy fibrin metabolism.*

How Our Ingredients Are Uniquely Effective

How Our Ingredients Are 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 to help protect them from stomach acid. Our serrapeptase and nattokinase undergo a cutting-edge process with a special pthalate-free polymer (MAAC). This increases efficacy by allowing more enzyme activity to pass through the stomach and reach the small intestine, where it is most needed.

If you’ve tried another brand without results, remember that working with acid-sensitive ingredients is complex science. Too often, other brands don’t want to do the hard work. When you look closely, these brands do not apply acid protection to their enzymes at all, or blindly apply it to everything. Sometimes they claim higher potencies to imply better efficacy, but completely fail to disclose what happens to all that potency in your stomach acid. Even worse, many brands intentionally confuse customers with cheap workarounds like delayed release capsules or ineffective substitutes for these powerful and delicate ingredients.

As a science-first company, we choose to sell this brand because it delivers the best ingredients in their best form, providing the best results.*

This is a reorder. Works great! My dermatologist thinks my improvement is from her limited steroid injections—but no—it’s from your product!

Serrakor NK

This has the highest FU ratings of any enzyme. I have had no problems with thickening of blood since I have using the last 10 years, while my 2 brother both have suffered 2 times with clots in their legs. It also can be used as a binding agent for anti-parasitics if you have taken too much of the anti-parasitic, ex. Fenbendazole or Ivermectin.

Serracor-NK

I have been using Serracor-NK since 2005 when my blood pressure was 280 over 180 and I ended up in the emergency room due to atherosclerosis. Within three weeks of taking Serracor-NK my blood pressure dropped to 120/80 and I lost 35 pounds. I have been taking Serracor-NK ever since, and now several of my family and friends do too.

Thank you

My first purchase of this type of product (the original one) was from Arthur Andrews years ago. There was some controversy between the developer of the product on the time released nature of it and how someone wanted to change the formula. Some of the details are vague at the moment but I have the letter I was sent in a file. Anyway I ended up purchasing from Biomedical Labs as I was having trouble getting the product from Arthur Andrews. To be hones I don't think the product is as potent as the original one. It could be different ingredients from different wholesalers, differences in my body's reaction to the product over the years etc. It's still a good product which I use but I sometimes feel something is missing.

Best one I found

I am taking to alleviate pain from blood clotting issues and wanted a natural remedy. Pain and pressure has been reduced considerably. Still have some discomfort but is more manageable now. I tried another brand but this one seems to work best.

Was looking for a systemic enzyme that actually worked. Most are full of fillers. This one hits the spot. I feel better after a few days of taking 5 capsules three times a day for a week. As my condition improves I will taper off to the maintenance dose.

Good choice for nattokinase

So far this is just as good as my usual choice that wasn’t available. It’s easy to swallow with the right amount (8oz) of water.

Not sure if the product will work as marketed since it in what appears to be a regular gel cap that can be dissolved by the stomach acid.

Great price for a product that does for me what it claims...joint swelling and pain began improving in 48 hours. 3 capsules 3 times per day with plenty of water.

Not for sensitive stomach

They did seem to help with inflammation for a couple of days. Then they gave me horrible diarrhea. I went down to one pill twice daily and still stomach pain and diarrhea. Hated that I had to stop...i have a sensitive stomach/ibs. Def can’t handle these.

Great Product for Aging Necks

I have used enzymes , on & off, for years. These enzymes relieved a very painful neck problem brought on by lifting as I prepare to move out of state. Plus being on Medicare I was reticent to continue with a pricey anti-coagulant med & so far on Nattokinase I am doing well. I have re-ordered.

Works great, really noticed a change in inflation and pain

As with most nutritional supplements its effects take a while to really kick in. HOWEVER I recently ran out and it only took a few days for me to realize just how effective it is. I highly recommend this product.

I used to have very high blood pressure (210/110) for many years ever since the rollout of 4G. Blood pressure meds only helped temporarily, then it slowly crept up again. Last month, I realised that my body was desperately trying to get sufficient oxygen to my brain and vital organs. Since taking Serracor-NK and Schuessler Tissue Salts (General Tonic) my blood pressure quickly went down to 145/90 within 3 weeks and is still falling.

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!!

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.

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.
