My heart had gone haywire for 3 years my heart would race then slow down, beat so hard my entire body shook, light-headed, dizziness and pain in my chest. Saw two robotic-like cardiologists. One said PVC. The other one said, sinus node and the cure for that is to burn the node and put a pacemaker in! No way!
I did extensive research. Saw an ND, he had me on 2 (200mg )magnesium 3x a day and increased my zinc. A friend begged me to try her supplement that has L-arginine, L-citrulline, d-ribose. But not in pill form it is not as effective. Some cardiologist are recommending to patients with Angina that seems to cure the problem in many cases. It's a powder formula with L-arginine, L-citrulline and d-ribose in it. It worked! Two weeks later no more heart problems and breathing easy.
Arginine, an amino acid, produces nitric oxide which may relax the arterial walls active, and it apparently lows blood pressure in some patients.
Heart issues have a cause that a cardiologist may not look at food allergies, dental cavitations hidden infection, parasites, mold or environmental allergies, and Electro magnetic sensitivity.
