What is arginine?

Arginine, also known as L-arginine, is one of the semi-essential amino acids. Nevertheless, it plays an important role for the human body as it is involved in many crucial processes.

Arginine can be produced by the body in certain amounts under normal circumstances. It is also found in certain foods, such as meat, a number of seeds and nuts, and grain products. Dried peas, unpolished rice, eggs, cow's milk, and salmon also contain large amounts of arginine.

The effect of arginine

Arginine improves oxygen supply and blood flow to the blood vessels. Because it contains a lot of nitrogen, it reacts with oxygen to form nitric oxide. This relaxes the heart muscle and expands the blood vessels. For this reason, arginine also has a positive effect on diseases such as arteriosclerosis and high blood pressure.

Arginine also strengthens the immune system because it stimulates the production of white blood cells. It is also said to have an anti-cancer effect and, for example, has a positive influence on the course of chemotherapy. It also promotes wound healing after operations. Arginine also supports the formation of collagen and therefore plays an important role in bone formation.

The amino acid also influences the body's hormone balance. It has a positive effect on the secretion of growth hormones. Arginine not only promotes muscle building, but also fat loss. That is why it is particularly popular with bodybuilders and other athletes and is used for weight loss. Diabetics also benefit from arginine because it increases insulin secretion in the body. Arginine also has a positive effect on male fertility and sexual performance.

Why arginine is important

Adults need additional amounts of arginine, especially during stressful phases of life. The need for arginine also increases with certain illnesses or after accidents. Arginine can be taken as a preventative measure during the cold season to strengthen the immune system. Athletes also have an increased need for arginine. In children with growth disorders, arginine can stimulate the release of existing growth hormone reserves.

A varied diet with plenty of nuts, eggs and milk is important for an adequate supply of arginine. In addition, special nutritional supplements can be taken that provide additional arginine, as there are hardly any known side effects of the amino acid.
