Dr. Louis Ignarro Ph.D.
Nobel Prize in Medicine
Author: NO More Heart Disease

 

 

Why Dr. Ignarro's Nobel Prize and Book are important to you.

  1. Dr. Ignarro's Nobel Prize for the discover of how Nitric Oxide is produced in the body signaled a medical breakthrough. Other Nobel Prizes were for X-rays, penicillin and insulin.

  2. Dr. Ignarro wrote the book on how to "Prevent and Even Reverse Heart Disease and Strokes."

 

How do you lower your Blood Pressure?
Dr. Louis Ignarro is one of three researchers who won the Nobel Prize in Medicine for their discovery of how Nitric Oxide regulates and protects our heart and blood vessels.

Or as the Nobel Prize press release puts it:
“We know today that Nitric Oxide acts as a regulator of blood pressure, as a gatekeeper of blood flow to different organs, as a signal molecule in the nervous system and as a weapon against infections.”

If you have sufficient Nitric Oxide, your body will regulate it’s own blood pressure.

But as we grow older, our body loses the ability to make Nitric Oxide and our arteries begin to block up.  In fact, by the time we’re 60 years old we are only making 15% of the Nitric Oxide we made when we were 20 and it’s in our 60’s that High Blood pressure and Cardiovascular problems start causing heart attacks and strokes.  


What causes High Blood Pressure?

High Blood pressure is almost always caused by narrowing of your arteries by a plaque or calcium buildup.   It's like putting your thumb over a garden hose.  You reduce the hose opening and you get a lot more water pressure.  
Your arteries work the same way.  Block any artery and the blood pressure goes up behind it.  Block it enough and you stop blood flow.  That's a heart attack or stroke.




L-arginine and “NO More Heart Disease”

Dr. Ignarro wrote a great manual for your heart called “No More Heart Disease” that details how to boost your body’s production of Nitric Oxide with L-arginine and L-citruline supplements to prevent and even reverse heart attacks and strokes.

Your body uses L-arginine to make nitric oxide, which relaxes the blood vessels. This reduces stress on the heart and improves circulation. L-arginine is the body’s major source for nitric oxide synthesis. L-arginine also reduces blood viscosity and many scientific studies have shown that l-arginine aids in reducing blood pressure levels.

"Father of ProArgi-9+"

"Over 20 years experience in clinical arginine therapy"

Why Dr. Prendergast's clinical experience is important.

  1. ProArgi-9 Plus has been tested in actual clinical use in Dr. Prendergast's clinic since he helped formulate it. No other arginine nutritional product can say this.

  2. Dr. Prendergast was using L-arginine therapy seven years before Dr. Robert F. Furchgott, Dr. Louis J. Ignarro and Dr. Ferid Murad received the Nobel Prize in 1998 for discovering what Nitric Oxide does in the endothelial cells. There are few doctors who have as much experience with clinical arginine therapy as Dr. Prendergast.

Since 1991 Dr. Prendergast has been using L-arginine therapy in the Endocrine Metabolic Medical Center with remarkable results. This is seven years before the Nobel Prize was awarded to Louis Ignarro, Robert F. Furchgott and Ferid Murad for discovering that L-arginine produces the signalling molecule, Nitric Oxide.

Dr. Prendergast brought his years of L-arginine research experience and clinical L-arginine therapy with thousands of patients in the Endocrine Metabolic Medical Center to the scientists at Natures Sunshine Products and together they formulated ProArgi-9 plus.

Since that time Dr. Joe has used the Synergy Worldwide product ProArgi-9 plus in his practice with phenomenal results.

Here is a 50-minute interview with Dr. Prendergast as he tells his own story.

Dr. Prendergast has been an researcher and Endocrinologist for over 35 years.
He is Board Certified in Internal Medicine as well as Endocrinology and Metabolism and served his residency at the University of California, San Francisco. Dr. Prendergast is a member of over a dozen national medical associations and has published over 50 medical articles in well-known publications including JAMA "Journal of the American Medical Association", "The New England Journal of Medicine" and "Diabetes Care".

During that time, Dr. Joe has empowered countless patients in the art of self-care.

"L-arginine benefits the body in a myriad of ways. We have now learned more about how l-arginine uses the two natural pathways into the brain to promote anti-aging properties, sports performance, and boost the immune system. Because l-arginine promotes healthy blood flow, it can also benefit human sexuality."
Dr. Prendergast

Dr. Prendergast is a graduate of Wayne State University in Detroit, Michigan. He completed his residency at the University of California, San Francisco. In 1986, Dr. Prendergast formed a single specialty endocrinology practice, Endocrine Metabolic Medical Center and a non-profit research foundation, The Pacific Medical Research Foundation. In 1999, he founded DiabetesWell, an eClinic that managed patients with diabetes and helped them lead healthier, longer lives.

Dr. Joe's first book, The Uncommon Doctor: Dr. Joe’s Rx for Managing your Health, reveals the secrets of preventive medicine and helps readers design a strategic wellness program. Dr. Joe hosts his own live Internet health program each week.

The High Desert Heart Institute
Human Clinical Study


The most comprehensive human clinical study ever conducted on a nutritional product.

Some results from the HDHI Study.

Why this clinical study is important to you.

  1. This is a PRODUCT study. Most clinical studies look at just one item, such as l-arginine to try and isolate and identify what that item does. Few studies investigate a product in this way. The HDHI chose to evaluate ProArgi-9+ as a product, which enables us to compare these results with real world results.
  2. This is a HUMAN clinical study. Many clinical studies involve rats and rabbits instead of humans to test results. It's important that the HDHI ProArgi-9+ study is a human clinical study.
  3. Most ARGININE based nutritional products refer to some vague research somewhere for scientific validation of their product. ProArgi-9+ has been tested in this clinical study as well as used in a medical clinic for over four years. No other arginine nutricinal product can say this.

In 2009, the High Desert Heart Institute began a comprehensive clinical study of ProArgi-9 Plus. HDHI was founded by Dr. Siva Arunasalam, who is an affiliate of Cedars-Sinai of Los Angeles and internationally respected for superior care of high-risk heart patients.


This video is an overview of the HDHI ProArgi-9 Plus study.
click below for video



For this study, 33 high-risk heart failure patients were selected. The vast majority of the patients in the study had reached the end of what medical science could do for them. They were at maximum drug levels, maximum supplemental oxygen and maximum therapy. Some of these patients were on a heart-transplant list.



There was nothing else for us to try, we had tried everything with these patients. All patients showed a tremendous improvement in many, many objective data points that only can be attributed to ProArgi-9 Plus
Dr. Siva Arunasalam

To scientifically measure the effects of ProArgi-9 Plus, every patient received extensive diagnostic testing for 13 weeks producing almost 7000 points of data. Each patient was given two scoops of ProArgi-9 Plus in the morning and two in the evening.

The results of the 90 day study were far more significant than anyone expected. Many of the patients were able to resume normal lives and the quality of life for almost all patients had improved dramatically.

It is important to note that these results are an average of all 33 patients. For instance not all patients had serious problems with peripheral blood flow, but the average of all patients was an increase of 16%.

Most of the patients were able to reduce the number of drugs or the amount of medications they were taking. The figures below are compelling because they reflect dramatic improvement as well as the reduction of medications.

A few of the results were as follows:

• C-reactive proteins decreased - 25%
• Triglycerides decreased - 40%
• Vitamin D levels increased by + 183%
• Creatinine levels decreased - 11%
• Pulmonary Hypertension dramatically improved
• Peripheral blood flow increased to the feet + 16%
(Measured by ankle brachial index)
• HDL Cholesterol increased + 18%
• Glucose levels reduced - 8%
• Magnesium levels increased + 35%
(There is no magnesium in ProArgi9 plus)
• Albumin decreased by - 70%
• Bilirubin decreased significantly
• Systolic BP decreased - 13%
• Diastolic BP decreased - 17%
• CASP decreased by - 6%
(Central Aortic Systolic Pressure)
• Decreases in platelets in the blood
• Quality of life measurements significantly improved for all participants

Interview with Dr. Siva Arunasalam

I expected a marginal improvement in the symptoms...what we ended up seeing was remarkable, positive, remodeling of the heart, positive pulmonary artery changes, pulmonary vascular changes...
Dr. Siva Arunasalam

Dan Austin is the R.N. in charge of every patient in this study. He saw first hand the amazing results of ProArgi-9 Plus from the beginning to the end.

I've been doing this type of work in critical care for well over 20 years and you see what congestive heart failure does. I have seen a dramatic, a dramatic reversal in Angelo's symptoms."
Dan Austin R.N.

Angelo Cici is a patient and part of the study. On Dec 20, 2008 Angelo had a simultaneous renal failure, congestive heart failure, conjestive pulmonary failure and a pace maker failure. From this point on he was in and out of the emergency room constantly. "I was so weak I couldn't even open a bottle of water by myself and I had decided I had had enough. I told the nurses I wanted all the IV's removed and I just wanted to go home and die."

"I was never going more than 5 days without going back into the hospital emergency room until I started taking ProArgi-9 Plus. ... it's been 6 months since I've been into a hospital. ...I feel like I'm 40 years old again."
Angelo Cici


Angelo Cici discusses some of the other patients in the HDHI Study.

Dr. Rainer Böger received his medical training at Hannover Medical School in Hannover, Germany. He received his postgraduate training in Internal Medicine and Pharmacology both in Hannover and at Stanford University School of Medicine in Stanford, CA.

Dr. Böger's scientific work centers on the early diagnosis and prevention of cardiovascular related diseases. Dating back to the beginning of his medical career, Dr. Böger has been heavily involved in the research and treatment of cardiovascular related diseases. In 1991, while working closely with pharmaceutical drug companies to develop treatments that could combat and alleviate such diseases, he became highly interested in nitric oxide (NO) and its effects on the vascular system.

Dr. Böger has dedicated 22 years of academic research in basic science and clinical studies related to L-arginine and its influence on the body's ability to produce NO. His major achievements are the discovery that ADMA (asymmetric dimethylarginine) is a risk marker of vascular disease and the utilization of L-arginine to prevent vascular dysfunction and disease.

Dr. Böger collaborates with renowned institutions like the Mayo Clinic and Stanford University Medical Center. He has documented his knowledge in more than 200 scientific articles, of which 130 exclusively cover the roles of ADMA and L-arginine in cardiovascular and metabolic diseases.

"With 22 years of basic and applied clinical research experience, I have made it my mission to use the discovery of these biological mechanisms to develop novel ways of enhancing cardiovascular health. As a clinical physician, I have treated patients who suffered from severe lack of blood flow to the legs, and it is this experience that has inspired me to research the benefits of L-arginine and its affect on tissue blood flow.

When using L-arginine as a dietary supplement, there are a few caveats that need to be considered. Restoring nitric oxide formation with L-arginine needs to be maintained around the clock. L-arginine, however, has a short residence time in blood; in less than 1 hour, half is already spent. Only when L-arginine is combined with L-citrulline is it possible to provide prolonged elevations of L-arginine in the blood stream.

Furthermore, cardiovascular health is a refined balance in which the endothelial cells interact with oxidative factors, blood platelets and the coagulation system, and transcriptional regulation of cell growth and development. Thus, additional components can interact with L-arginine to promote cardiovascular health on a multifactorial level.

With its unique blend of l-arginine and other supportive ingredients, it is my experience that Synergy's ProArgi-9+ provides an optimized way to enhance your cardiovascular system compared to other nutritional supplements on the market." Dr. Rainer Boger

Nitric oxide (NO) is one of the smallest molecules in the human body, but like oxygen (O2), it plays an extraordinarily important role for maintaining a healthy life. Nitric oxide keeps arteries wide, so that oxygen can be easily delivered to all the organs where it is needed.

NO is produced, in many different cell types throughout the body, from the amino acid precursor, L-arginine. The conversion of Larginine to NO makes it a very unique amino acid that is of essential nutritional importance.

The site of NO production determines its biological effects:

  • In the arteries, NO keeps blood flow high and keeps arteries smooth and flexible.
  • In the gut, NO enhances intestinal function and prevents obstipation.
  • In the airway system, NO helps keep air flowing freely to the lungs.
  • In the brain and nervous system, NO decreases pain sensation and contributes to good memory formation.

By enhancing NO production, L-arginine is able to promote all of these effects. Thus, it is no wonder that such a huge diversity of organ functions are positively affected by L-arginine supplementation. Some people may call it a wonder, but I call it the science behind L-arginine.

Indeed, people with all different kinds of health concerns have reported improvements in their health status while on regular L-arginine supplementation.
One true fact needs to be considered, though, when one contemplates about this broad variety of health benefits: None of them can be achieved if L-arginine levels in blood are not successfully elevated above “normal” for 24/7. Only combinations of L-arginine with L-citrulline have the biological potential to achieve this goal, and only ProArgi9+ has been scientifically confirmed to do this.

This product’s success is also explained by some of its additional ingredients that support ProArgi9+’s effects on stimulating NO:

  • Resveratrol, the powerful antioxidant contained in red wine, supports the biological actions of NO on cells by reducing toxic oxygen radicals that may not only destroy the NO molecule, but also cause severe harm to the cell itself.
  • Vitamin D3 has been known as a vitamin that is good for bone health; however, medical research in the last few years has revealed that it is also an important regulator of glucose and fat metabolism, of blood vessel function and cell growth.

Thus, the power of ProArgi9+ is in the quality and science coming with its ingredients
