This article is educational and not intended to diagnose, treat, or suggest any specific intervention, and should not replace qualified medical advice.
What Does L-Citrulline Do?
L-Citrulline supports muscle endurance by raising arginine levels, which increases nitric oxide and blood flow during exercise.
L-citrulline helps muscle indirectly by increasing nitric oxide levels in the blood. This leads to better circulation, improving oxygen and nutrient supply during exercise. It can reduce fatigue and soreness, making recovery faster. L-citrulline is often preferred over L-arginine because it is more efficiently absorbed. By improving endurance and recovery, it supports greater training volume, which contributes to long-term muscle gains.
It boosts nitric oxide, which widens blood vessels for better performance.
Supplementation may delay fatigue, allowing longer training sessions.
It reduces ammonia buildup in muscles, lowering exercise-related tiredness.
L-citrulline helps improve recovery markers like soreness after heavy workouts.
