Chemical and Physiological Functions

• Physiological Functions: L-Citrulline has antioxidant properties, promotes blood circulation, and helps the body produce arginine. Arginine aids in cell division, wound healing, and the removal of ammonia from the body.
• Mechanism of Action: L-Citrulline does not participate in protein synthesis but has the ability to form peptide bonds. In the body, it can be converted from the natural amino acid glutamic acid through a series of enzymatic reactions.

Food Sources

• L-Citrulline is mainly found in the seeds of cucurbitaceous plants, such as watermelon juice, wild watermelon leaves, walnut kernels, walnut seedlings, and seeds.
• Eating watermelon or drinking concentrated watermelon juice can provide a good source of citrulline.
• High-protein foods such as meat, fish, protein powders, milk, and beans also typically contain significant amounts of citrulline.

Pharmacological Effects

• L-Citrulline has a significant role in preventing and treating prostate diseases and improving male sexual function.
• It enables the body to produce nitric oxide, which is an essential substance for male sexual function.
• L-Citrulline also exhibits physiological functions such as scavenging free radicals, serving as an indicator for allograft rejection, promoting vasodilation, stabilizing blood pressure, diagnosing rheumatoid arthritis, and exhibiting antioxidant properties.

Additional Information

• L-Citrulline is receiving increasing attention in the food, cosmetics, and pharmaceutical industries due to its broad range of potential applications.

In summary, L-Citrulline (L-Citrulline acid) is a non-protein amino acid with various physiological functions. It is widely found in food sources, especially in watermelon and other cucurbitaceous fruits. In the human body, it plays a role in antioxidant activity, promoting blood circulation, and helping the body produce arginine, among other functions, having positive effects on health and athletic performance.
