L-Arginine Benefits

L-Arginine HCL, as its name suggests, is made of 100% pure natural Arginine. Arginine is one of the 20 unique Amino Acids that your body uses to form proteins and, therefore, carry out the process of muscle growth and repair. Arginine is also a conditionally essential Amino Acid, this means that it is often necessary to consume more Arginine from your diet for your body to receive the benefits of it, rather than simply leaving your body to make it independently.

Muscle growth

As an Amino Acid, L-Arginine is one of the building blocks that your body uses to create muscle protein, which goes on to grow and repair tissue for larger, stronger muscles. This is an especially important process for if you are aiming to work towards training goals or make physical adaptations to your body.


If your goals are more than muscle related, it is important to note that L-Arginine can translate the other benefits of protein, which is commonly used in diets as a means of satisfying hunger, which can lead to a lower food intake and less weight gain. This phenomenon explains the popularity of the Atkins diet, which is an incredibly popular method of dieting in which undertakers substitute their carbohydrate intake for a greater supply of Amino Acid rich protein.


Beyond just benefits for your muscles, the L-Arginine also has implications for your circulatory system. Once ingested, L-Arginine forms Nitric Oxide in the body, which people often use to dilate blood vessels for greater blood flow. This can help improve circulation as well as complement your ability to prevent damage to your blood vessels and relieve blood pressure. The importance of circulation can be seen from a muscle perspective because the circulatory system is a never-ending highway that carries nutrients to the muscles for use when exercising. The maintenance of sound circulation is also important to the heart, and can prevent the wearing and deterioration of blood vessels and the adverse problems associated with this.
