L-arginine is one of the 20 most naturally accruing amino acids in the body, and it is one of the main building blocks used by the body to create complex proteins. Although naturally produced by the body it can also be found in many food products from animal derived products such as milk, cottage cheese, yoghurt, and whey protein.
Most seafood also contains L-arginine, as do most pork products, beef, oatmeal, wheat germ, wheat flour, granola, most nuts, soybeans and chickpeas. The amount of foods its present in means that no matter what their diet, L-Arginine is naturally a part of everyone's diet.

It helps with a vast number of problems, but as well as these, it also helps to boost the body immune system. Making life easier in many ways, from shaking of a cold quicker, to helping fight against infections and illnesses. Although there are a few side effects, which are generally small in most cases, the benefits of L-arginine are numerous.
L-arginine has many helpful properties in the body, not only as a building block for complex proteins, but it also helps in the removal of waste products from the body, most importantly ammonia. In larger amounts, it can also stimulate the release of hormones such as growth hormones and prolactin.
Although research is still ongoing and the benefits of L-arginine are still being discovered, it is known, or thought, to have many useful properties. One of its functions is in the production of creatine, it as been known since 1939 that L-arginine is necessary and essential for this process. Creatine is widely used by bodybuilders and athletes as it not only increases body mass but also their strength.

L-arginine is also needed in the process to make nitric oxide, which is essential in the body, in fact nitric oxide is so important to the body as almost everything in the body depends on it. It can increases blood flow and circulation, which is useful not only for the heart, but as many cases of erectile dysfunction can be put down to poor circulation, taking L-arginine supplements can help many solve this problem.
