L-Citrulline

L-Citrulline is a non-essential (conditionally essential) amino acid, meaning that our body cannot produce sufficient amounts of L-Citrulline under exertion, and therefore, L-Citrulline must be taken in the form of dietary supplements. In our body, L-Citrulline is found as part of proteins that make up our hair, skin, and nerve cells. L-Citrulline is produced in our intestines from glutamine but can also be found in some foods such as watermelon.

Citrulline regulates metabolic processes and the nitrogen level in the body. It serves as the basis for the synthesis of L-Arginine and L-Ornithine, amino acids crucial for athletes. Citrulline contributes to the dilation of blood vessels as it forms the basis for L-Arginine, which then converts to nitric oxide, relaxing the muscles around the blood vessels. This ensures that muscles receive more oxygen and nutrients while eliminating toxins. By expanding blood vessels, blood pressure automatically decreases, providing an additional benefit of L-Citrulline. Citrulline improves agility and endurance by reducing fatigue. It also aids in recovery after strenuous activities.
