L-arginine, also known simply as arginine, is an amino acid with strong vasodilating effects. This means that the nutrient helps to support the natural relaxation of arteries to promote strong blood flow when it is needed, as is the case in erectile function that depends on robust blood flow to the penis.
Under normal circumstances, the body produces enough of this vital amino acid to meet a man’s needs. However, in times of physical or emotional stress, the body’s natural stores of L-arginine can become depleted. In such cases, it can be helpful to take the amino acid in supplement form. But please observe professionally recommended dosages.
Because it promotes better vascular function, L-arginine is obviously a useful ally in getting and keeping an erection suitable for intercourse. While it can’t match the more potent vasodilating effects of Viagra and the other PDE5 inhibitors, it can provide a helpful boost to erectile function in times of illness or stress.
Natural food sources of L-arginine include a wide array of high-protein animal- and plant-based foods. Animal foods rich in L-arginine include eggs, fish and other seafood, poultry, and dairy foods such as cheese, milk, and yogurt. Among the plant-based foods high in the amino acid are beans, chocolate, nuts, oats, and seeds.
