L-Citrulline supplements are a type of dietary supplement that contain the amino acid L-Citrulline. This amino acid is naturally found in watermelon and is involved in the body's production of nitric oxide. Nitric oxide helps to dilate blood vessels, which can improve blood flow and oxygen delivery to muscles during exercise. Some studies suggest that L-Citrulline supplements may also help to reduce muscle soreness and improve endurance. These supplements come in various forms such as powders, capsules, and tablets and are popular among athletes and fitness enthusiasts.
