L-Citrulline is an amino acid that plays a significant role in the urea cycle, which helps the body eliminate toxic ammonia through urine. It's also known for its ability to increase levels of L-arginine in the blood, which can enhance the production of nitric oxide (NO). It has been shown to help with the following: Improved Vasodilation, Improved Exercise Performance and Recovery, and Hormonal Support.

One of the key functions of L-Arginine Hydrochloride is its involvement in the production of nitric oxide (NO). Similar to Citrulline Malate, L-Arginine HCl acts as a precursor to nitric oxide, which is a potent vasodilator. By promoting the relaxation and dilation of blood vessels, nitric oxide helps improve blood flow throughout the body. This enhanced circulation can have several benefits, including better delivery of oxygen and nutrients to muscles during physical activity, leading to increased endurance and reduced fatigue.

The primary reason for combining L-Arginine with Alpha-Ketoglutarate is to enhance the potential benefits of L-Arginine. Like other forms of Arginine, AAKG is a precursor to nitric oxide (NO) production. Nitric oxide is a powerful vasodilator that relaxes and widens blood vessels, promoting increased blood flow to muscles and organs. As a result, athletes and bodybuilders often use AAKG to support their exercise performance, as improved blood flow can lead to better oxygen and nutrient delivery to working muscles, potentially increasing endurance and reducing muscle fatigue during workouts.
