L-arginine, also known as arginine is a semi-essential amino acid necessary for the production of protein. The human body can produce 10 of the 20 amino acids, one of which is arginine, but supplementation is common, especially in adults as the production of this amino acid decreases with age. Arginine is necessary for a number of bodily functions and is a critical component for the secretion of hormones such as growth hormone, glucagon and insulin. It also promotes immune function, wound healing and removes excess ammonia from the body.
Infertility and Pregnancy Benefits
According to health professionals at Medline Plus, arginine is used for erectile dysfunction. Thus, it may help couples trying to get pregnant. The amino acid is converted into a chemical called nitric oxide, which causes blood vessels to expand and allows for greater blood flow. Arginine is also used as a cream for treating sexual problems in both men and women.
Additional Benefits
L-arginine is also used for heart and blood vessel conditions such as congestive heart failure, chest pain and coronary artery disease. It is also beneficial for preventing the common cold, improving kidney function and athletic performance, and boosting immune system function. Women can enhance training sessions by supplementing with L-arginine before working out to reduce fatigue and recovery time from intense exercise sessions.
Food Sources
Most arginine in the American diet is obtained from meat and fish sources, which puts vegetarians at risk for deficiency. Plant sources rich in the amino acid include beans, brown rice, bran, chocolate, legumes, oatmeal, popcorn, raisins, sesame seeds, soy, sunflower seeds and whole grains. Nuts such as walnuts, Brazil nuts, peanuts, cashews and almonds are also rich sources. Animal sources include milk, pork, beef, chicken, turkey and seafood. Consuming a wide variety of these foods will reduce the chances of being arginine deficient.
Considerations
L-arginine is generally well tolerated by most people but side effects may include bloating, diarrhea, nausea, rash and may also cause high white blood cell count. You should always consult your healthcare professional before making changes to your current diet or supplement plan. Inform your healthcare professional about any adverse reactions you may experience.
