Heart disease, blood pressure lowered by L-arginine

In 1998, a team of pharmacologists won the Nobel Prize for their discovery of how nitric oxide (NO) regulates blood flow in the body, for example, NO can causes dilation of blood vessels.

L-arginine is an amino acid known to cause the human body to produce NO. It is found in beef, chicken and dairy products. Apart from heart and circulation benefits, it is used in cases of angina and where people have congestive heart failure and blocked arteries; in America L-arginine has even become popular as a dietary supplements for helping men achieve peak performance in the bedroom.

L-arginine helps improve blood circulation and helps support normal blood pressure levels. L-arginine is converted into NO and this can dilate your blood vessels, so your heart doesn’t have to pump as hard. This has all been confirmed by research. For example: One meta-analysis, of 11 randomized, double-blind, placebo-controlled trials involving 387 patients taking from 4 to 24 grams per day of L-arginine showed that L-arginine lowered systolic blood pressure by 5.4 mmHg and diastolic BP by 2.7 mmHg.

Other supplements of benefit include Alpha Lipoic Acid (ALA), Folic Acid, B-12 and vitamin D.
