Enzymes (Neprinol, Nattokinase and Fibrozym) for Peyronie’s Treatment

Enzymes Used to Treat Peyronie’s Disease – (Neprinol, Nattokinase and Fibrozym)

There is probably no single area of natural Peyronie’s disease treatment that is more researched and offers greater potential to reduce the Peyronie’s plaque and restore a curved penis than the use of natural systemic enzymes.   For many years PDI has used Neprinol, Nattokinase and Fibrozym with great success.

An enzyme is a protein molecule that either starts or speeds up a chemical process without being used up or consumed in the process that it affects. Enzymes are found all around us and in us; they start or continue many thousands of complex chemical reactions that occur continuously throughout the body. They have been called “the fountain of life” because without them life could not exist.(1)

Go to our special FAQ page for answers to frequently asked questions about Peyronie’s treatment.

The enzymes working in your body at this moment got there in one of two ways:

1. Enzymes that come from within you – the supply you had at birth, or those you make from proteins already inside your body. There are just so many enzymes available to you from the start of life; you were born with just so many enzymes, and they will not last forever. It is estimated that by the time the average person reaches the age of 27 – 27 years old! – the body and health begin to decline because that is the usual halfway point of available enzymes supplied at birth. Sobering news, don’t you think? It is even more sobering to know some people are born with more and some are born with fewer enzymes available for their use. This can explain the variability of health and lifespan from one person to the next, no matter how well or how badly someone takes care of their body. Science is beginning to see that health and lifespan are largely determined simply by the supply of enzymes you have at the start of life. A person therefore is wise to protect the enzymes they have, (and pay attention to this next paragraph).

2. Enzymes brought into your body from the outside – those supplied in whole or in part from the enzyme-rich foods that are eaten. Up to 40% of the proteins reorganized and rearranged in the body from dietary sources are used to produce more than 3,000 different enzymes found in the human body. Unfortunately, the enzyme content of food has significantly decreased due to overuse of soil, food processing, refining and preservation techniques, and a decreased consumption of fermented foods and fresh foods, which are high in enzymes.(2) This makes enzyme supplementation important to everyone, especially the man with PD.

Enzymes are critical to every aspect of life activity. Digestion is the first enzyme function that usually comes to mind. However, other enzyme dependent activities abound, such as energy production, brain function, elimination, detoxification, reproduction, muscle contraction, vision, cardiac activity, respiration, healing and repair, immunity and defense, and so on. We spend a lifetime using our enzymes to trigger every activity of life. Since they cannot be put back into the body as fast as they are being used, we deplete our reserve of enzymes as we get older. All the systems and functions that depend on enzymes – and that means all of them – sooner or later begin to weaken and falter: digestion becomes a problem; needing more rest than before; muscle mass declines; hearing, sight, and smell diminish; memory…memory… well, I forget what happens to memory. As enzymes become more rare, we experience what is called “getting older”.

Running low on enzymes affects fibrous tissue also. Enzymes circulate in the blood as part of the immunity and defense systems, to weaken and eliminate foreign invaders (bacteria and viruses) and remove foreign substances (cellular debris, blood clots, and other things that don’t have a good purpose in the body like unnecessary scar tissue). As enzyme levels get lower this defense function against fibrous tissue buildup begins to decline also. Here are examples of the inability to keep up with fibrous tissue buildup as we get older: Joints (knuckles, wrists, knees, etc.) get thicker and stiffen; the lens of the eye hardens (bifocals); heart valves stiffen (heart murmurs); tiny fibrous blood clots occur and arteries harden (circulation and blood pressure problems); muscles shorten (stooped posture), and so on. Throughout life fibrous tissue attempts to invade all areas, tissues and organs of the body, in a process called fibrosis. During youth the enzymes circulating in the blood keep this process in check, keeping you looking and feeling pretty good. With age there are fewer enzymes to remove the advancing army of fibrous infiltration, and slowly the fibrous tissue gains more and more territory in the body. PD can be seen as a part of the process of fibrous tissue buildup. It might begin earlier with some men, later in others, after injury in some men, without injury in others – but it happens.

PDI knows you have never read in any medical website a simple, common sense and broad explanation of PD that fits into the larger picture of life as the one you have just read. Think about it. This explanation gives you understanding and power over your PD. It becomes apparent there is another direction to take – enzyme therapy – toward controlling some of the fibrous tissue infiltration in your penis, as well as benefiting other areas and aspects of your general health.

This section could easily be the longest of all since the topic of enzymes is so enormous. Hopefully we have explained this simple idea: Enzymes are necessary for every aspect of your life and health. As we get older and eventually run low on enzymes, problems start to occur like fibrous buildup in the body. Taking enzyme supplements should build up your reserve, supporting the innate ability to function at a healthier capacity.

What the research tells us about Peyronie’s treatment

The immense body of enzyme research done to this point has been focused on major problems of health and healing that have a wide and common interest to society — such as diabetes, cancer, Alzheimer’s disease, and many others. Little research effort appears to have been spent investigating a condition as relatively obscure as PD. Once again it will be necessary to take what is found about one condition or tissue and see how it applies to PD.

In the opinion of PDI, nattokinase, serrapeptase, bromelain and papain are the four primary enzymes that demonstrate in research trials adequate ability to affect the fibrous material of the PD scar. Here is a discussion of each of these.



Nattokinase is an enzyme discovered in a traditional Japanese cheese-like food, called natto. It is made from boiled soybeans to which a friendly bacteria, Bacillus Natto, has been added. Natto has been used in Japan for over a thousand years as a folk remedy for heart and vascular diseases. While other soy foods contain other enzymes, it is only the natto preparation that was found to contain the specific nattokinase enzyme.

In 1980, Dr. Hiroyuki Sumi discovered nattokinase while he was completing his chemistry degree at the Chicago University Medical School. He was in the process of testing 173 different foods, and several types of liquor, for their ability to promote healthy circulation when he found that natto dissolved fibrous clot tissue and improved circulation better than any of the other substances he tested. The enzyme responsible for the increase of blood supply was named nattokinase.(3,4)

Since its discovery, additional research has been done on nattokinase including 17 published studies in Japan and in the U.S.(5-21) The results have been very exciting because of the affect nattokinase has on improving circulation and how this affects the entire body – along with our speculation how this increased blood flow benefits PD. Healthy blood flow is the transport vehicle that delivers enzymes, nutrients, antibodies, and oxygen to every cell, regulates body heat, and removes waste products. Without good blood circulation true health is not possible. Among the enzymes that are depleted with age are those that constantly dissolve and remove small blood clots from the tiny capillaries all over the body. One of the enzymes that reduces and controls blood clotting is called plasmin, and it too diminishes over time. What makes plasmin important is that it can safely take apart or remove fibrin if it becomes necessary. Fibrin is a thread-like protein fiber that binds with several other elements in the blood to form an insoluble network, eventually becoming a blood clot. Sometimes you want a clot, and sometimes you don’t; the body knows the difference, but that is another story. Anyway, the connection of PD to fibrin is this: before a scar becomes a scar it more closely resembles a clot with fibrin. If the fibrin gets out of hand because there is not enough plasmin to control the fibrin, the big mass of fibrin can turn into a large scar. Plasmin and plasmin-like substances (nattokinase) are of interest in PD because of their potential to take care of the scar in its early stage while it has a lot of fibrin in it. As the enzyme plasmin diminishes with age, blood clots increase along with other fibrous tissue problems – like PD.

A second way in which nattokinase can help PD is by increasing blood circulation. An example of the ability of nattokinase to improve circulation comes from Biotechnology Research Laboratories and JCR Pharmaceuticals, Kobe, Japan.(21) They tested nattokinase’s ability to dissolve a blood clot in the carotid arteries of rats. Of the animals treated with nattokinase, on average they regained 62 percent of their blood flow, whereas those treated with plasmin regained just 15.8 percent of blood flow. More proof comes from JCR Pharmaceuticals, Oklahoma State University, and Miyazaki Medical College when they tested nattokinase on 12 healthy Japanese volunteers (6 men and 6 women, between the ages of 21 and 55). Volunteers were given 200 grams of natto (the food) before breakfast, then their ability to dissolve fibrin was determined through a series of blood tests. The tests indicated that natto increased the ability to dissolve blood clots: On average, the time it took to dissolve a blood clot dropped by 48 percent within two hours of treatment, and this ability to dissolve clots was retained for 2 to 8 hours. As a control, researchers later fed the same amount of plain boiled soybeans to the same volunteers and tracked their clot dissolving ability; this group showed no significant change.

Enzyme product information

This concludes the technical discussion concerning ENZYMES. What follows next is the presentation of commercial information about a particular product that PDI endorses and sells in its Natural Complementary Medicine Products division. PDI does this so that you may easily identify what we think is the best therapy product of its kind, and then make it available for sale easily and at the best price we can.

Please bear in mind that PDI cannot answer your questions or help you with your therapy plan if we do not have knowledge, experience or confidence with “foreign” therapies. On the PDI website we clearly state, “Sorry, but due to the volume of emails PDI receives and with limited hours available in a day, we can only answer questions from PDI customers. When you purchase your therapy products only from PDI you have full access to the vast experience and careful assistance available to our customers. If you purchase inferior grade or questionable bargain products elsewhere, you will have to rely upon that source for whatever help you might need later.”

We take this position because after doing this work since 2002 we sincerely believe that you stand a better chance to reverse your PD if you only use products listed in the PDI and Natural Complementary Medicine websites.

The benefit of nattokinase to increase circulation is real. Any potential healing and repair that should take place in a PD scar will be more likely to take place in the presence of a good blood supply to bring in all needed enzymes and nutrients, as well as to remove waste products.

Nattokinase 1500 is a powerful and basic ingredient in most Peyronie's treatment plans
Nattokinase 1500

Nattokinase works to support healthy circulation in several important ways:

1. Nattokinase resembles plasmin, so it prevents fibrin from clumping in the blood. This keeps the blood “thinner”, or as the scientists would say “less viscid”. Blood that is thinner flows freer and easier, is less likely to clot, it makes for better circulation and all that a good blood flow can accomplish in the body.

2. Nattokinase resembles plasmin, so it can break down clots directly after they have formed. In fact, a study points out that the ability of nattokinase to break down a clot is actually four times greater than plasmin or elastin.(9,13)

3. Nattokinase increases the natural production of the enzyme plasmin, which also helps to keep the blood thin, break down clots and other fibrous materials in the body.

How do you know if you might benefit from nattokinase? Here is a list of symptoms that suggest a reduction of blood in the body.  See if you recognize yourself in this list. If you do, then perhaps nattokinase could be of great potential benefit to you.

1. Hands or feet, cold, numb, tingle

2. Thick skin on hands or feet

3. Fingernails thin and break easily

4. Loss of physical stamina you once had; get winded easily

5. High blood pressure

6. History of cardiovascular disease

7. Memory not as good as it used to be

If you have any of these going on, you should consider adding nattokinase to your treatment plan.

Summarizing the benefits of nattokinase:

1. Supports normal circulation, blood flow, and blood viscosity (keeping it thin enough to flow well).

2. Supports normal blood-clotting mechanism directly via affect on fibrin fibers.

3. Supports normal blood-clotting mechanism indirectly via production of plasmin, which reduces fibrin fibers.

4. Maintains normal blood pressure levels by keeping fibrous material out of blood vessel wall and reduces small blood clots in capillaries.

5. PD application: same effect on plasmin and fibrin are suspected to be beneficial on fibrous material of early scar development.

Serrapeptase – as found in Fibrozym

This interesting enzyme comes from human-friendly bacteria known as Serratia E15, found in the gut of silkworms. Serrapeptase is used by the silk worm to dissolve the cocoon as it attempts to emerge as a moth. In humans, serrapeptase has been shown to act as an anti-inflammatory, anti-edema factor, and a pain-blocker in a large number of tissues, much like aspirin, ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs).(22) Research indicates it may even help inhibit plaque build-up in arteries, thereby preventing atherosclerosis (hardening of the arteries) and resulting heart attack or stroke. For this reason serrapeptase has been called “the second gift from the silk worm.” The ability of serrapeptase to reduce fibrous tissue infiltration into blood vessels walls is the reason it is of interest to PD. Unlike aspirin, this naturally derived enzyme does not cause ulcers and stomach bleeding.

With no direct research into the effect of serrapeptase on PD, it is again necessary to compare and theorize the effect of serrapeptase in similar situations for possible benefit to PD.

Cystic Breast Disease Serrapeptase has also been used in the successful treatment of fibrocystic breast disease. The PD connection is the chronic inflammation and development of fibrous tissue of the breast cysts. This fibrous tissue is similar to the type of tissue in scars and feels firm, thick, rubbery, and ridge-like, very much like PD. In a double-blind study, 70 patients complaining of breast engorgement randomly were divided into a treatment group and a placebo group. Serrapeptase was superior to the placebo for improvement of breast pain, breast swelling and hardening. 86% of patients receiving serrapeptase reported moderate to marked improvement. Mechanism of action appears to be serrapeptase’s ability to clear out all inflammation and dead tissue. By alleviating the inflammation and clearing away this problem tissue it relieves the symptoms and allows the healing system to rapidly repair the problem. No adverse reactions to serrapeptase were reported and the researchers concluded that “serrapeptase is a safe and effective method for the treatment of breast engorgement.” (23-25) PDI speculates the same tissue response occurs in PD.

Trauma In Germany and other European countries, serrapeptase is a common treatment for inflammatory and traumatic swellings, and much of the research that exists on this substance is of German origin. One double-blind study was conducted by German researchers to determine the effect of serrapeptase on post-operative swelling and pain. One study involved sixty-six patients who were treated surgically for fresh rupture of the lateral collateral ligament of the knee. On the third post-operative day, the group receiving serrapeptase exhibited a 50 percent reduction of swelling, compared to the controls. The patients receiving serrapeptase also became pain-free sooner than the controls, and by the tenth day, the pain had disappeared completely.(26)

Hardened arteries Hans A. Nieper, M.D., noted Germany internist, studied the effects of serrapeptase on the formation of artery plaque (deposits of fatty substances, cholesterol, cellular waste products, calcium and fibrin, a clotting material in the blood). According to Dr. Nieper, only three 5 mg tablets of serrapeptase daily for 12 to 18 months are sufficient to remove fibrous blockages from constricted coronary arteries, as confirmed in many of his patients by ultrasound examination. He called serrapeptase a “miracle” enzyme because it digests non-living tissue, blood clots, cysts, arterial plaque (scar) and inflammation in all forms. However, the evidence to support serrapeptase’s role in preventing plaque build-up is anecdotal, since it remains unproven in the usual research sense. Still, further studies are called for in this area as Nieper’s research indicated that the protein-dissolving action of serrapeptase will gradually break down atherosclerotic plaques.(27) All of this has nice application to PD.

Carpal Tunnel Syndrome This condition involves thickened and inflamed ligament tissue at the bend of the wrist, causing considerable pain and numbness of the hand and fingers. In this study, use of serrapeptase proved to be a useful alternative mode of conservative treatment.(28)

Infection and Post-Operative Recovery There are many reasons to use serrapeptase after surgery. It is useful for the pain, inflammation and tissue response after tissue injury, as well as for its ability to assist recovery in a wide variety of traumas. (29-33)

Serrapeptase is thought to work in three ways:

1. It may reduce inflammation by thinning the fluids formed from injury, and facilitating the fluid’s drainage. This in turn, also speeds tissue repair.

2. It may help alleviate pain by inhibiting the release of pain-inducing amines called bradykinin.

3. It may enhance cardiovascular health by breaking down the protein by-products of blood coagulation called fibrin. Conveniently, serrapeptase is able to dissolve the fibrin and other dead or damaged tissue without harming living tissue. This could enable the dissolution of atherosclerotic plaques without causing any harm to the inside of the arteries.


Bromelain is a proteolytic (protein-digesting) enzyme of plant origin. Bromelain, also known as bromelain, is extracted from the flesh and stem of the pineapple plant, Ananas comosus. For years natives in the tropics have used this plant as a folk medicine.(34) More than eight protein-digesting components have been identified in bromelain.(35) Studies have shown the beneficial effects of bromelain in the treatment of inflammation and soft tissue injuries (36,37). These results suggest that bromelain can be useful in many conditions where soft tissue injury occurs.

Pineapple has been used as a medicinal plant in several native cultures and bromelain has been known chemically since 1876. In 1957, bromelain was introduced as a therapeutic compound when Heinicke found it in high concentrations in pineapple stems. Bromelain is most notable for its effectiveness in the reduction of inflammation and decreasing swelling, but the wide range of its known benefits continues to increase. As a natural anti-inflammatory enzyme, bromelain has many uses. Arthritis patients may reduce joint swelling that causes pain by taking bromelain. Bromelain may also be helpful for the pain, numbness, tingling, aching, and loss of motor and sensory function in the fingers resulting from carpal tunnel syndrome.

More than other enzyme supplements, bromelain should be recognized for the one major ability that is not found in any other potential therapy that is so easily, readily and economically available to the man with PD. Bromelain is unique among the protein digesting enzymes in its suspected capacity to stimulate secretion of collagenase. This particular enzyme, collagenase, is most important to PD because mature and developing scar tissue is primarily made of collagen. Collagen is degraded or digested by collagenase. And as was just stated, “bromelain is suspected to increase secretion of collagenase” that can take apart and remove the collagen material that makes up the major part of scar tissue. This is great news for the PD sufferer! Bromelain increases the enzyme that takes apart the major building material of scar tissue.(38) That single bit of information should be enough to motivate a guy with PD to jump out of his chair and order some protein-digesting enzymes, especially bromelain.

In addition, bromelain has several other abilities in relation to soft tissue healing: it inhibits clot formation, breaks down fibrous tissue,(39) reduces inflammation, and it has skin debridement (wound clearing) properties. Other less direct benefits are its ability to enhance absorption of drugs and nutrients, and to enhance the immune response to allergies. Bromelain is well absorbed orally and available evidence indicates that its therapeutic effects are enhanced with higher doses. Although all of its mechanisms of action are still not completely understood, it has been demonstrated to be a very safe and effective therapy. All in all, bromelain has many large, medium and small benefits for the man with PD.

Here is a simple example from everyday experience that will demonstrate the ability of bromelain to digest the collagen of scar material.

Gelatin (Jello) is made from the same protein (collagen) that is abundant in muscles, bones, and other tissues of animal body parts (typically hooves). When gelatin is dissolved in water, heated, and then cooled, it forms a familiar rubbery semisolid material, such as you have likely seen at one time or another on a pot of beef soup that has cooled or in the form of gelatin salads (Jello) or mousse.

Since gelatin is a protein primarily consisting of collagen, it is susceptible to enzyme activity. The enzyme bromelain is found in fresh pineapple and breaks the bonds of collagen, so gelatin will not gel in the presence of fresh pineapple or fresh pineapple juice. If you were to take two packages of Jello, and prepare one with canned pineapple juice and the other with fresh pineapple juice you would find that they would not look the same after they set for the usual time. The one with canned juice would look just like regular Jello. The one with the fresh pineapple juice would never set or become a semisolid. This altered state of the Jello would occur because the bromelain of the fresh juice would digest or break apart the collagen molecules and prevent them from reforming as they should. As another example, bromelain is also used to tenderize meat (Adolph’s meat tenderizer), since it also breaks the bonds of collagen.

Bromelain has been shown to exert a beneficial effect at doses as low as 160 mg/day, however, there is a general consensus among researchers that the best results occur when bromelain is given in doses above 750-1,000 mg per day and that results improve in a dose-dependent manner as you go to higher dosage levels. Bromelain has been demonstrated to be well absorbed, and has been shown to be safe at high doses for prolonged periods of time. Most research on bromelain has been done utilizing divided doses, and findings indicate that results are dose-dependent, meaning that the more you take of it the better the results.(40)


In the 25-30 years serrapeptase has been used, it has a good safety record. However, as with every substance one consumes, there is the potential for risk. Just because something is “natural” doesn’t mean it is automatically harmless. Certainly, the ongoing controversy over the regulation of nutritional supplements indicates that one needs to be cautious and informed when using any supplement. While naturally derived supplements can be beneficial and safe, they can also be harmful if used carelessly or without the help of a medical professional.

Serrapeptase is a powerful enzyme that has a few cautions. After prolonged use of serrapeptase some gastrointestinal irritation can occur, though this is rare. There is also the increased risk of infection of the lung and pneumonia when using serrapeptase. This also is rare but is a possibility because serrapeptase thins mucus secretions, leading to lung complications if one has a history of lung problems. Studies with serrapeptase do not extend over a long period of time. Therefore, the long-term effects of serrapeptase have not yet been determined.

Peyronie’s disease connection

An important aspect of PD not previously mentioned in other sections concerns its frequent occurrence with two other problems that can be related to fibrous tissue build up. Various reports state from 20-40% of men with PD also have elevated blood pressure and/or hardening of the arteries. This is important to PD because one cause of high blood pressure can be fibrous tissue blocking small blood vessels, and another can arise from fibrous tissue infiltration into the blood vessel walls. It should be of interest to anyone with PD that these three problems – PD, high blood pressure and hardening of the arteries – all can share this fibrous tissue element, and they all can be caused or aggravated by reduced enzyme activity.

PD can be seen, in whole or in part, as a symptom of the decline of available enzymes needed to remove unnecessary fibrous tissue. Therefore, an effective therapy for PD could be simply to use specific enzymes to support the immune and defense system against fibrous infiltration and foreign proteins. If we supplement with primary protein digesting enzymes then the body will start an “enzyme cascade” creating thousands of new enzymes from the enzymes that are supplemented into the body. Everything else we do in regards to nutrition and health will work better after we boost diminished enzyme levels in significant amounts. Once in your system, the enzymes will work to reduce and remove foreign protein and unnecessary fibrous tissue. Since enzyme replacement therapy is being used successfully in hospitals and clinics all over the world for a wide variety of other health problems, there is no logical reason it should not be attempted for PD.

William Bodri has written an excellent book, “The Naturopathic Approach to Peyronie’s Disease”, in which he devotes two chapters to the use of enzymes in treatment of PD. He is very excited and confident of the great potential enzymes offer in treatment of PD, as is PDI. He refers to the ability of various enzymes to “bust up and help remove” foreign proteins and fibrous materials from the body. His book covers important material that could not be covered here, and is recommended for its original thinking, keen insight and wealth of valuable information about Peyronie’s treatment . Go to TheSkepticalNutritionist.com., where his book can be downloaded off the Internet.

More than 3,000 protein-based enzymes start or speed up over 7,000 vital reactions in the body. You have seen an enzyme can be very specific in what it does; those enzymes of interest for PD – nattokinase, serrapeptase and bromelain – give adequate evidence they have great potential in an effort to reduce the fibrous material of the PD scar.

Enzymes are needed for life. The idea behind taking enzymes to treat PD is to use a natural process of breaking up and eliminating fibrous tissue and foreign proteins. That’s what these enzymes appear to be designed to do – break up the bad stuff that should not be there, like that nasty PD scar. The body has a wisdom that detects the presence of these abnormal cells and tissue elements, and removes them whenever and wherever possible – you want to take advantage of that wisdom. PDI relies heavily on two enzyme products in particular because of their potential affect on PD scar tissue. You are taking advantage of the latest and the best of recent science when you use enzyme therapy to support and stimulate the body’s defense system. As always, talk to your doctor about taking any of these powerful enzyme products.

Enzyme Product Recommendation

Neprinol is the most popular Peyronie's disease treatment today.  Its enzyme base is broad and more concentrated than others.

NEPRINOL From research and investigation in this area, PDI realizes that not all enzyme products are equally effective. NEPRINOL® AFD is one of the best enzyme products PDI has found with sufficient potency and quality that it can be relied upon to treat the effects of PD. One of the industry standards is to measure enzyme potency or strength by “activity levels”. In measuring the ability to reduce fibrous tissue, this ability is expressed by “FU’s” or “fibrinolytic units”. Most enzyme products suggest a usual dose of 1-2 capsules at a time, providing an average of 1,000 – 2,000 FU’s. This is pretty much standard for the average enzyme product. Therefore, it would be wise to select an enzyme product on the basis of the FU’s it produces per dose, rather than the milligram weight per serving. NEPRINOL® AFD provides 15,000 FU’s per serving, yielding 133% higher activity levels. This is the reason PDI is really excited about NEPRINOL® AFD.

Soy Free Neprinol-AFD can assist the body to reduce scar tissue buildup, fibrosis, arthritic conditions, pain, swelling, inflammation and hundreds of other ailments. NEPRINOL’s formulation is more complete and essential than a daily vitamin. Replace the enzymes that Mother Nature removes as we age. NEPRINOL® is radically more advanced than today’s leading systemic enzyme blends. NEPRINOL® contains several sources of anti-oxidant fighting ingredients, as well as the full spectrum of proteolytic (protein digesting) enzymes, enterically coated to adapt to a wide spectrum of pH levels. NEPRINOL’s exclusive formulation contains several highly concentrated digestive enzymes that enable the body to digest fats, proteins, carbohydrates and sugars. These digestive enzymes convert the food we eat into energy rather than stored fat.

NEPRINOL® AFD is the most scientifically advanced broad spectrum enzyme blend available. NEPRINOL® AFD uses individually enterically coated enzymes to increase pH range and resistance to stomach acid. NEPRINOL® AFD is the first systemic blend with 100% pharmaceutical grade components and the purest form of Serrapeptase, Nattokinase and CO-Q10 available. Several years of scientific research and clinical studies have been conducted on each and every component that makes up NEPRINOL® AFD. For the first time ever, you can get all of these enzymes in one powerful product.

NEPRINOL® AFD contains three primary ingredients, a well as several others that serve in a supporting capacity, that function to reinforce the stores of the enzyme system of the body. Serrapeptase to break down fibrin within the body and modulate the immune system, Nattokinase to improve cardio-vascular health and help eat away arterial plaque, and finally CO-Q10 regarded as one of the most potent and effective antioxidants available. CO-Q10 will fight free radicals and aid in reducing stress on the heart.

Notice that the cost for a bottle of NEPRINOL® is higher than some of the other enzyme products, but this is because it is more concentrated and comes in a larger size bottle than most. On a cost per capsule and cost per “FU” NEPRINOL® is a less expensive than all others.

Do not take NEPRINOL® without the consent of your physician if you are currently taking anti-coagulants or you are pregnant or lactating (as these subjects have not yet been tested).

Nattokinase 1500 is an enzyme product for Peyronie's treatment that is included in all three model plans created by PDI becaue it is well tolerated and effective, without distressing hte digestive tract
Nattokinase 1500

Nattokinase For those looking for a pure, potent source of nattokinase without having to travel to Asia, look no further! Nattokinase 1500 from Wobenzym USA provides a whopping 1500 fibrin units (FU) of nattokinase per serving.

For over 50 years the German company, Wobenzym, has studied and published more material than any other enzyme manufacturer in the world. Their signature product, WobenzymN, is said to be “the single-most researched enzyme product” in the world. If any company understands the benefits and mechanisms of enzyme therapy, this is the one. Of all the companies who produce enzyme products in the world, Wobenzym is the standard by which others are measured. With that kind of research and product development ability, you can rest assured that their Nattokinase 1500 product is an outstanding product.

We recommend this product because of the reputation and integrity of the Wobenzym name, and their huge commitment to product research. Dr. Sumi, discoverer of the nattokinase enzyme recommended a dosage of 2,000 fibrin units of nattokinase a day. Nattokinase 1500 has, as the name suggests, 1,500 fibrin units per two tablets, making this a simple and easy requirement to reach. We have found no other product that matches this one for supplement strength and value.

Fibrozym is so wonderful for all Peyronie's treatment plans because it contains Serrapeptase, Bromelain and Papain -- a powerful trio of enzymes to reduce penile curvature

Fibrozym Fibrozym contains Serrapeptase, Bromelain and Papain — a powerful trio of enzymes that can be especially beneficial to the reduction fibrous and scar tissue in the body.

Comprised of a hypo-allergenic, high-purity strain of serrapeptase, and plant-based bromelain and papain enzymes, Fibrozym normalizes the inflammatory response and improves overall tissue health. In addition it contains a high potency bromelain and bromelain to compliment and increase its fibrous-tissue busting ability. PDI has not found another product that combines Serrapeptase, Bromelain and Papain in such a high potency formula; this makes Fibrozym a unique and powerful addition to you PD therapy program .

Unlike other products, Fibrozym is an enterically coated table, allowing it to pass through the stomach without being digested or degraded . Other non-enterically coated products, which get digested in the stomach, become less effective once they finally reach the bloodstream.

Wobenzym introduced at the end of the summer of 2004 a new product called Fibrozym, that is their “fibrinolytic enzyme for tissue well being”. Fibrozym has ten times the amount of serrapeptase activity than their closest competitor, Vitalzym and Zymitol. It is coupled with an effective dosage of bromelain, papain and other support to create what we think is an outstanding product. Fibrozym supplies in heavy therapeutic dosage of the enzymes (serrapeptase, bromelain and papain) research has found to be so important for healthy tissue repair. PDI thinks this is the product we have been waiting for.

With just these two products – Fibrozym and Nattokinase 1500 – it is possible to bring a world of enzyme benefit directly to your PD treatment plan.

Dosage of enzymes for Peyronie’s treatment

Nattokinase 1500 – Two tablets three times daily, on an empty stomach. Absorption works best if there is no food (no digestion) taking place when you take this product. Therefore, take “on an empty stomach” means taking this product at least an hour before or two hours after eating. Many people take Nattokinase 1500 at a low dose, 1-2 per day, for health maintenance.

Fibrozym – Three tablets three times daily for 1st month and then reduce to 3 per day, on an empty stomach. Absorption works best if there is no food (no digestion) taking place when you take this product. Therefore, take “on an empty stomach” means taking this product at least an hour before or two hours after eating. It is recommended you take Fibrozym for 3-4 months and then stop to evaluate further need. Fibrozym can be taken at a low dose, 1-2 per day, for health maintenance. Maximum: Up to 30 tablets per day only for acute trauma care for several days, until symptoms subside. Dosage this high not recommended for PD.

Neprinol Dosage for Neprinol is a little more complex.   For this reason, special instructions are included with each order.

  1. Thomas Palazzi says:

    This Article has been very informative. I use to sell Wobenzym and I know how good the product is. I Have PD and I’m at stage where I have to do someting NOW!! NOT GETTING VIAFLEX SHOTS OR PUMP!! IM MARRIED 4 YRS! NEED HELP AND I BELIEVE IN THESE PRODUCTS. Leaning to Natt 1500 and/or Fibrozym. Thx Alot!!

  2. Theodore Herazy says:

    Greetings Thomas,

    Yes, the enzyme section of the PDI protocol is extremely important to treat Peyronie’s disease. However, you must use more than enzymes to get the kind of results you want; you must also use a variety of several other internal therapies (MSM, PABA, acetyl-L-carnitine, vitamin E, etc.) as well as external therapies. Peyronie’s disease is a complex and difficult problem that does not respond well to limited and minimal treatment efforts. When men follow our suggestions for using the large PDI treatment plan, on average 8-10 report moderate to marked improvement of their PD for every one who reports failure. Pretty significant changes for a difficult problem, plus no side effects and no return of the PD like you get with surgery. Please read a little more about what we do and how we do it, and ask questions if you need more help with your Peyronie’s disease. TRH
