What is L-Citrulline?

L-Citrulline is a non-essential amino acid found naturally in certain foods and produced within the body. It plays several important roles in bodily functions and is known for its potential health benefits, particularly in supporting cardiovascular health and exercise performance.

Health benefits of using L-Citrulline:

1. Nitric Oxide Production:

L-Citrulline is converted into another amino acid called L-arginine in the body, which then leads to increased production of nitric oxide (NO). Nitric oxide acts as a vasodilator, relaxing blood vessels and improving blood flow. This effect can have various health benefits.

2. Blood Circulation and Cardiovascular Health:

By promoting vasodilation and improving blood flow, L-Citrulline may help support healthy blood pressure levels and overall cardiovascular function. It assists in maintaining healthy circulation and endothelial function.

3. Exercise Performance:

L-Citrulline is commonly used by athletes and individuals involved in physical activities. It may enhance exercise performance by increasing blood flow to muscles, improving oxygen and nutrient delivery, reducing fatigue, and potentially improving endurance.

4. Ammonia Removal:

L-Citrulline may assist in the removal of ammonia, a byproduct of protein metabolism that can build up during intense exercise, contributing to fatigue.

5. Detoxification Support: 

It contributes to the urea cycle, a process involved in the removal of ammonia from the body, aiding in detoxification.


L-Citrulline is available as a dietary supplement in various forms such as powders, capsules, or tablets. As with any supplement, it's advisable to consult with a healthcare professional before starting L-Citrulline supplementation, especially for individuals with existing health conditions or who are taking medications. Dosage and suitability may vary based on individual health status and needs.
