About Neprinol

Supports clean blood, proper joint and circulatory function.

Fibrin is found in the blood, and is necessary for healing after injury, infection, and disease. But the production of fibrin is not a perfect process. Your body normally keeps fibrin in check by using enzymes to break down any excess. However, after age 30, enzymes become scarce and fibrin begins to build up.

When fibrin builds up, it can act like a cobweb in the veins and arteries, trapping toxins and setting off an immune response. This may cause you to experience the following symptoms:

  • Fatigue and discomfort
  • Poor circulation
  • Elevated blood viscosity
  • Delayed healing

Neprinol helps decrease excess fibrin with fibrinolytic activity that surpasses most other products. Its systemic enzymes aid in detoxifying and purifying the blood, which supports optimal cardiovascular and cellular health. This non-toxic blend of enzymes helps to reduce bruising, swelling, and pain from over exertion. It also supports a healthy inflammatory response, helping to limit daily aches and pains.

Get the right blend of systemic enzymes that your body needs for proper circulation and improved joint comfort with Neprinol.

*From exertion and overuse

A fibrinolytic enzyme derived from the fermentation of Bacillus subtilis that can help to maintain normal blood viscosity and normal cardiovascular health.


A proteolytic (protein digesting) enzyme with potent fibrinolytic activity can support healthy fibrin concentrations. It has been clinically shown to support healthy mucus viscosity and promote normal recovery after physical stress.


Used systemically, this enzyme digests fats in the blood and can help convert fats into fatty acids, which may be expressed or retained as energy.


A proteolytic enzyme that, when present in blood serum, plays an important role in the blood’s health. It can also help support a healthy immune system and improve circulatory health.


Derived from Indian Gooseberry, amla contains tannic acid, glucose, cellulose, and calcium. Amla helps maintain pH balance, and has a high concentration of naturally derived vitamin C.


A proteolytic enzyme derived from papaya that can promote normal healing and inflammation from overexertion.


A flavonoid (plant pigment) that helps to maintain strong capillaries and connective tissue, as well as healthy blood vessels.


Helps to decrease the proliferation of free radicals, supporting a healthy immune system. Co-Q10 helps promote maintenance of normal cardiovascular function and is a coenzyme that is essential for enzymes to function in the body.

I've been taking neprinol for about six months. When I ran out and didn't reorder, I started noticing a difference in how my digestion works. I believe it's beneficial to me to take it and I'll continue to do so.

I started using Neprinol AFD around October 2015 for a nagging knee problem I began experiencing in late 2014. Despite using doctor prescribed steriods and other medications for a few months none of them had any positive effect for me. Neprinol AFD was recommended to me by my natropath and I'm happy to say that there has been noticeable improvement thus far.

We love this supplement. We order it, we take it, we feel better, we order more. I made the mistake of trying to live without it when we ran out and we paid the price. We started getting sick with the flu, colds, everything everyone else was getting. I am placing another order today so we don't run out.

Great for eliminating bothersome inflammation in the joints and muscle. Not to mention no more heartburn. I'm a strong believer in it.

I am so grateful a product exist that does what this product does. Everything you need for healthy arteries, fibrin control And enzymes for functions in the body are available.
After reading all the reviews on Neprinol I have to order it and theSerretia. I had a stroke in 2009 and the warfarin and Statin drugs they put me on had me in constant pain and almost crippled. When I was in the hospital I felt great, couple of weeks later the pain in my body was crippling and I was using a walker and cane to get around. I quit taking the Statin and eventually felt much better. Now I have stopped taking all the warfarin cut back to half dose and taking nattokinase and a baby aspirin daily. Started to see results immediately. Now I am ordering Neprinol with added Seretia. I would recommend it to anyone for sure.

I am not stiff anymore. I use it along with Serrapeptase. Feeling younger!
