Citrulline is an amino acid essential for proper cardiovascular function and physical performance. Studies suggest that citrulline supplementation may increase the availability of L-arginine and nitric oxide (NO) production, which contributes to blood vessel dilation, improved blood flow, and better delivery of oxygen and nutrients to the muscles. As a result, citrulline may reduce fatigue, enhance recovery, and increase exercise capacity, especially in endurance and strength sports. Numerous studies have demonstrated its benefits in improving both aerobic performance and post-exercise muscle recovery.
Endurance athletes, such as runners, cyclists, and triathletes, may benefit from citrulline supplementation due to its ability to boost blood flow and oxygen delivery to working muscles, allowing for prolonged high-intensity activity. Meanwhile, strength athletes and bodybuilders will appreciate its ability to increase nitric oxide production, which may lead to a stronger “muscle pump” and improved muscle performance during strength training. Additionally, athletes in team sports like football, basketball, or hockey can benefit from citrulline supplementation through enhanced recovery between games or training sessions, leading to better readiness for exertion.
Why supplement citrulline?
- Faster muscle recovery – reduces muscle acidity by more effectively removing ammonia and other metabolites created during intense exercise.
- Support for endurance and strength athletes – particularly recommended for sports requiring prolonged intense muscular work.
- Increased muscle pump – improved blood flow makes muscles fuller and better nourished, enhancing training quality.
- Fatigue reduction support – improves oxygen and nutrient delivery to the muscles, which may enhance exercise tolerance.
Who is citrulline for?
- Individuals training in strength sports and bodybuilding who want a better muscle pump.
- Endurance athletes such as runners, cyclists, and swimmers looking to extend muscular endurance.
- Physically active individuals wanting to reduce fatigue and improve recovery.
- People aiming to support nitric oxide production for better blood flow and muscle oxygenation.
