HOW IT WORKS: L-Arginine can help treat several heart conditions because of its ability to increase the production of nitric oxide (NO). NO helps dilate or relax blood vessels so that blood flows more freely through the body, relieving high blood pressure, congestive heart failure, and angina. In addition, NO prevents blood clots and plaque buildup, which can lead to a heart attack or stroke. Because NO also helps increase blood flow to the sexual organs, arginine may also be useful in treating erectile dysfunction in men. Arginine supplementation during periods of stress (such as infection, illness, or injury) is beneficial because the body requires a greater amount of this amino acid for healing purposes. Arginine is also required by the pituitary gland for the production of growth hormone, which supports the immune system and is depleted as we age, leading to wrinkles, weight gain, bone and joint disease, and hair loss DID YOU KNOW… Soy protein and other plant proteins are richer in L-arginine than animal proteins, which are richer in lysine. RESEARCH: The efficacy of supplementing with L-arginine for many conditions has been demonstrated in numerous studies. In human clinical trials, L-arginine has had significant positive effects in hypercholesterolemic and hypertensive subjects. It has also been helpful in those with angina pectoris. In a recent long-term study, supplemental L-arginine, given for 6 months, resulted in significant improvement in coronary small-vessel endothelial function. In a double-blind, placebo-controlled study of 22 subjects with stable angina, supplemental L-arginine (1 gram twice daily) significantly improved exercise capacity. In another study, L-arginine supplementation resulted in a 70% reduction in angina attacks SIDE EFFECTS: No side effects expected in dosages up to 3 grams per day. Mild side effects include gastrointestinal upset and nausea.
