L-Arginine is a nutrient that is abundant in many different types of foods like, red meat, fish, poultry, wheat germ, grains, nuts and seeds, and dairy products, moreover, your body can make it since it is a non-essential amino acid, thus deficiency of Arginine is a rare case, nevertheless, it has gotten lots of attention lately for its potential health benefits, specially for the heart.

Arginine is normally needed for

An important aspect of L-Arginine is that it is the precursor of Nitric Oxide (NO), which dilates blood arteries by relaxing their lining smooth muscles and decreasing their resistance to blood flow, thus lowering blood pressure. It may improve symptoms of clogged arteries, chest pain or angina, and coronary artery disease. It may also help with erectile dysfunction.MayoClinic
