L-arginine – meaning, sources, supplementation, deficiency effects

L-Arginine is a “new” wonder supplement. It is supposed to support the work of the heart, build muscle mass and improve well-being. L-arginine is indeed one of the key compounds in the body that affects its entire functioning, but is its supplementation really needed? Below you will find answers to all the most common questions about L-arginine.

What is L-Arginine

L-arginine is an amino acid that can be made in the body from glutamic acid and proline. In this respect, this relationship is endogenous. It happens, however, that in exceptional situations the body loses the ability to synthesize L-arginine and it is necessary to increase its supply with food.

Functions of L-arginine in the body

The importance of L-arginine in the body is closely related to the fact that it is involved in the production of NO (nitric oxide). This compound has a positive effect on the functioning of the entire circulatory system – for example, it seals blood vessels. The presence of L-arginine in the body protects against coronary heart disease and regulates blood pressure. It also helps maintain an erection by increasing the amount of blood that flows through the blood vessels. So we can find it in Hemp4Love for sexual satisfaction – a dietary supplement with CBD available at a favorable price on Medonet Market.

What’s more, L-arginine promotes the work of the thymus and the maturation of immune cells, which has a positive effect on the functioning of the immune system.

This amino acid is also important in the regeneration of tissues – both soft and hard. Thanks to this, it supports the process of cancer healing, but also bone fusion. This has to do with the fact that arginine helps in the process of cell division.

An important issue is also the fact that the compound supports the building of muscle tissue, ensuring the correct figure.

L-arginine also regulates the secretion of many hormones, especially growth hormone.

Finally, the compound is used in dentistry. L-arginine solution is successfully used in the treatment of tooth hypersensitivity.

Effects of L-arginine deficiency

L-arginine deficiency is a relatively rare condition. This is mainly because the body has the ability to produce it on its own. However, it has been proven that the efficiency of its creation decreases with age. Preterm babies also have impaired L-arginine synthesizing function. A deficiency of this amino acid may also appear in the exhaustion of the body resulting from a poor diet.

Too little L-arginine in the body can lead to an imbalance in insulin secretion. In addition, the metabolism of fats in the liver may be disturbed, leading to damage to this organ. The deficiency of the amino acid also leads to abnormalities in the muscle tissue, and with prolonged deficiency, even to its disappearance. Due to the fact that arginine affects the synthesis of NO – a key molecule for the proper functioning of the circulatory system – its lack can lead to heart disease.

L-arginine sources

Certain amounts of L-arginine are produced by the human body (provided, of course, that the body has adequate amounts of proline and glutamic acid from which it is synthesized). However, these amounts may not be sufficient for the proper course of metabolic processes. Therefore, it is difficult to clearly define whether L-arginine is an endogenous or exogenous amino acid.

Fortunately, the human body has the ability to absorb L-arginine from food. The good news is that this compound can be found in both animal and plant-based foods. A rich source of l-arginine is dairy, seafood, as well as white and red meat. Vegetarians can find it in all types of nuts and seeds, whole grains, granola, chickpeas and soybeans.
