High Desert Heart Institute L-arginine Clinical Trial

High Desert Heart Institute

The HDHI did the most comprehensive human clinical study every conducted on a nutritional supplement. Their results with ProArgi9 are stunning.

Why this clinical study is important to you.

  1. This is PRODUCT study. Most clinical studies look at just one item, such as l-arginine to try and isolate and identify what that item does (visit a site to get more information on how trials are designed). Few studies investigate a product in this way. The HDHI chose to evaluate ProArgi-9 Plus 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 Plus 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 Plus has been tested in this clinical study as well as used in a medical clinic for over three 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.
Dr. Siva Arunasalam

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.

ProArgi9 is a Synergy nutritional product formulated by Dr. Joseph Prendergast and manufactured by Nature Sunshine for Synergy WorldwideProArgi9 is a food supplement with L-Arginine and L-Citrulline and other incredibly good-for-you ingredients to strengthen the cardiovascular system.

My Visit to Meet Dr. Joseph Prendergast

I flew to Salt Lake City, Utah and saw Dr. Joseph Prendergast in person.  Dr. Prendergast is from California, and he is the developer of ProArgi9.  I cannot begin to tell you how excited I am about Synergy, and about the ProArgi9 product.  Dr. Prendergast is an amazing scientist and doctor.  His fame for being “The Uncommon Doctor” is quickly spreading.  A little background on “Dr. Joe” (his preference) will explain why I went to meet him…

  • Dr. Joe is an Endocrinologist, with the primary focus through his career on Diabetes
  • Diabetics don’t die of Diabetes – they die of the complications which often is cardiovascular related problems
  • Following a series of strokes that began at age 42, Dr. Joe’s father died heart disease when Dr. Joe was 19
  • Although Dr. Joe was an athlete and a runner, and led a very healthy lifestyle, at age 37 he had an abdominal scan which revealed generalized atherosclerosis – a condition he inherited from his father’s genes – essentially, his cardiovascular system was like that of an 85-year old – he was a walking heart attack ready to happen at any moment
  • Timing and location and who you know are everything – Dr. Joe was at Stanford and associated with some very famous doctors who were involved in research that led to a Nobel Prize in medicine, specifically the role of L-arginine and Nitric Oxide in cardiovascular health
  • Dr. Joe became probably the first person to experiment with taking L-arginine into his own body – he knew he had nothing to lose – and the results where that in a very short time the “age” of his circulatory system improved dramatically.  Today, at age 73, because of what he learned and the nutritional approach he developed and uses Dr. Joe’s vascular system is the “age” of a 15 year old
  • Equipped with his own personal experience of solving his circulatory system health, as well as the resources of his colleagues and the Nobel Prize winning research of three American doctors, Dr. Joe formulated a nutritional concoction known today as “ProArgi-9” which he has treated his patients with for many years.  Since 1991, he has treated more than 7,000 patients with  this nutritional supplement and not even one of his patients has had a stroke.  Not even one has had a heart attack.  Prior to ProArgi-9, Dr. Joe used to refer 30% of his diabetic patients for bypass procedures.  Today, less than 1% of his patients need to see a cardiologist for any reason.
  • ProArgi-9 has numerous ingredients that work synergistically together to accomplish its mission.  L-arginine obtained from the drug store will not work very well.  Once in the body the effectiveness of L-arginine lasts for a “few seconds” and while the benefit is great the coverage beyond those few seconds makes it ineffective in providing any significant value in fulfilling its true mission which is to enable the body to produce Nitric Oxide at the specific location of all of the internal surface area of the entire circulatory system.  ProArgi-9 is able to do what other L-arginine products cannot do in that it delivers a continuous supply of L-arginine throughout the circulatory system for up to 36 hours of coverage per dose.
  • The High Desert Heart Institute in California just recently concluded a clinical study of ProArgi-9 on 33 heart transplant candidates who had totally exhausted all known medical options and the only remaining hope for their continued life was a heart transplant.  All 33 received ProArgi-9.  All 33 patients got well enough so they no longer qualified to remain on the heart transplant list.  People who could not even walk 10 feet are now walking miles and miles.  Patients who were confined to the hospital have gone home and now have their lives back again.  The results of the clinical study are currently under review by a medical statistician in preparation for submission for publication in a medical journal.
  • The product does not just work for sick people.  It works for everyone.  Athletes are using the product because it helps with muscle recovery and it promotes human growth hormone which improves the ratio of lean tissue to fat tissue.  New Olympic records are being set because of the science in ProArgi-9.   Many people are using this product and having incredible things happen to their health.
  • The same research that led to ProArgi-9 nutritional supplement also led to Viagra and related drugs, but because ProArgi-9 is a food supplement and it is not a drug it is safe and it does not produce the side effects like drugs designed to produce similar results.
  • Many people who are using ProArgi-9 are getting off of their blood and heart medications like statins.  No more Lipitor for me!

So, with that background, perhaps you can see why I took two days to fly out to SLC to meet Dr. Prendergast in person.  I started on ProArgi-9 and it immediately knocked my blood pressure right down into the very desirable range.  It immediately dropped my bad cholesterol way down into the very desirable range, and my good cholesterol is sitting nicely in a better-than-target position.  It immediately dropped my triglycerides down into the very desirable range.

My degree is NUTRITIONAL SCIENCES.  I chose that course of study because I believed with the information I learned I could help people live longer and enjoy better health.  In my opinion, ProArgi-9 is the best nutrition product I have ever seen or used in my entire life.  It appears to help every person who uses it.

I recommend every person use this product.
