Arginine is a nonessential amino acid meaning that most of the time, the body can manufacture it and it doesn't need to be additionally consumed through the diet. However, the body doesn't naturally produce enough of this amino acid, so it must be consumed to some amount though the diet. It is especially important for individuals with poor nutritional practices or physical conditions may be advised to increase their intake of arginine via foods that contain the amino acids or supplementation.
This amino acid is very important as it plays a critical role in cell division, removal of ammonia from the body, wound healing, release of hormones and optimal immune system function. It has also been combined with other ingredients such as yohimbe to aid in treating erectile dysfunction. It has been clinically studied and oral supplementation of L-arginine has shown numerous benefits, primarily involving the heart. These benefits include being a pre-cursor to nitric oxide, reduce healing time of injuries, decreasing blood pressure and expedite the repair of damaged muscle tissue.
Animal sources of arginine include dairy products like cottage cheese, milk, yogurt and whey protein. Other sources such as gelatin, poultry, beef, pork, wild game and seafood. There are also many sources from plants that you can obtain arginine from including flour, granola, oatmeal, nuts, seeds and cooked soybeans.
