Review on Solgar L-Arginine 500 mg 250 Veggie Caps – Boost Nitric Oxide for Cardiovascular Health! by Jennifer Clark

L-arginine was prescribed to me by a Mayo Clinic cardiologist 33 years ago to be taken four times a day. The product prevents heart pain during physical exertion. I've tried several brands and can't tell any difference for my heart. However, I stuck with the Solar brand because they have good quality control. For example, capsules are always the same size, capsules are completely filled with product, and Solar does not go beyond the law to promote its product. I am now 85 years old and take many other heart medications. Maybe I can add something to my good health with L-arginine.
