Athletes and fitness enthusiasts – L-Arginine supplements are a favourite in the athletic community because of the nitric oxide it creates in the body. Nitric oxide has been shown to reduce muscle fatigue, improve endurance levels, increase energy, speed up recovery rates, and increased use of glucose (which means burning body fat). On top of all of these naturally enhancing health benefits, L-Arginine has been shown to trigger the production of proteins in the body. It also has been shown to increase lean muscle mass. Thus, arginine enhances fat burning effect, build muscle, and improve performance.

Aging individuals – Endothelial cells are the linings of our arteries and our blood vessels, and these cells need arginine in order to create enough nitric oxide to maintain healthy blood circulation. Research suggests that our ability to produce nitric oxide decreases as we age and taking arginine supplements can possibly counteract that.

Vegans and vegetarians – Sometimes it is hard with a vegan diet to ensure that you are eating enough dietary protein. An L-Arginine supplement can help ensure that your body is getting enough amino acids, which are the building blocks of proteins.
