L-citrulline

L-citrulline is an amino acid that occurs naturally in some types of food, especially in watermelons. In your body, it's converted into another amino acid, L-arginine, which is a precursor to the production of nitric oxide. This process helps improve circulation and can positively impact heart health and lower blood pressure.

Improving circulation and increasing blood flow

L-citrulline is a precursor to L-arginine, an amino acid that is crucial for the formation of nitric oxide (NO). Nitric oxide helps relax and widen blood vessels, which increases blood flow. This is especially beneficial during physical activity, as it allows for better oxygen and nutrient delivery to your muscles. After exercise, the increased blood flow contributes to faster recovery and greater muscle growth.

Boosting endurance and improving physical performance

L-citrulline is often used in sports nutrition because of its positive effects. Increasing your nitric oxide levels can enhance blood flow to your muscles during physical activity, contributing to greater endurance, improved performance, and reduced fatigue. This allows for longer and more intense workouts.
