 We recommend to look for the book "NO MORE HEART DISEASE", written by Dr. Louis J. Ignarro, who was awarded the Nobel Prize in Medicine in 1998 for his discovery of the importance of nitric oxide to the cardiovascular system. In Dr. Ignarro’s own words, “Nitric oxide is the body’s natural cardiovascular wonder drug.”

Rudy Cortez - Arginine Heart Health Expert

Hello. My name is Rudy G. Cortez, senior managing partner and co-founder of Heart Disease Defense in San Antonio, Texas.  I currently reside in San Antonio, Texas and have lived here most of my life. I appreciate and always enjoyed cultural diversity and growth from home and across the world. My influences came from meeting several interesting people from across Texas and around the United States as I toured as a professional Tex-Mex accordionist. I also enjoyed meeting people throughout Europe while serving my country with the US Air Force.

It was the influences of politicians and higher ranking officials, who I met during my military Mariachi performances, that led me to persue a Pre-Med BA degree at St. Mary's University in San Antonio,Tx. I attended a summer camp at Texas A&M medical school and shadowed physicians at Scott & White medical facilities.

It was during this education process that my eyes opened up to the injustices that were taking place in the medical industry.  I had recently seen this in the latin music industry.  The doctors were frustrated and going through almost the same thing my recording musician peers were going through as a result of not knowing the rules of the music industry. At that time I went on to became a music activist and consulted the AFM American Federation of Musicians to organize and raise awareness for the rights of recording artists.

Today as a former music activist and military veteran, I take pride in defending and protecting the freedom of rights, natural health and free enterprise opportunities in America.  I support like-minded people who want to manage their own health naturally and willing to work hard to build their own economic recovery instead of waiting for government bail-out.  Who wants to wait until they're sick to start managing their health and let ObamaCare take care of them?  Not me.

I once heard that "the true mark of greatness is not where we are today, but where we intend to be tomorrow".

Today, we are collaborating with growing entrepreneurs in Texas that can help us serve Nationwide and Canadian clients.  We are expanding into global markets with Nature Sunshine and Synergy with a mission to save a million lives from heart attacks and strokes.

Feel free to review our Arginine Heart Health website and discover what I believe to be the best Proactive Heart Health Solution in the planet!   We have specific plans that can Dramatically Change and Saving peoples Lives!

We are very excited about the current shifts that are taking place in America and around the world. We encourage you to take a look at our recommended proactive Arginine program and let us walk you through the process of attaining better Heart health.
