L-Arginine

Arginine is a conditionally essential amino acid, meaning our body can produce enough arginine under normal circumstances. However, during physical or mental exertion, our body needs more arginine than it can produce. Arginine contributes to protein synthesis in the body and can act as a substrate in the formation of nitric oxide in blood vessel cells – nitric oxide widens blood vessels and supports our immune system. According to many studies, L-arginine promotes the secretion of insulin and growth hormone, thus promoting muscle building. The widening of blood vessels contributes to the circulation and oxygen and nutrient supply to the muscles. In this way, arginine can improve our athletic performance – endurance during intense training and greater muscle definition.

L-arginine also contributes to creatine synthesis and is therefore often found in pre-workout products or in supplements for athletes and bodybuilders. Additionally, arginine supports our immune system, aids in the digestion of carbohydrates, cell regeneration, lowers cholesterol levels, and accelerates wound healing. Arginine is suitable for everyone who trains intensively. It widens blood vessels and supplies muscles with nutrients; training lasts longer, and fatigue is reduced. It also enhances sexual ability, which is why arginine is taken by 50% of users along with tribulus. L-arginine is convenient to take in powder form.
