Citrulline 1000 100 Caps from Vitobest is a dietary supplement specially designed for athletes looking to enhance their physical performance. Each capsule contains 1000 mg of L-Citrulline, a non-essential amino acid that plays a vital role in the urea cycle, helping to eliminate ammonia, a toxic byproduct of protein metabolism that contributes to muscle fatigue. The key advantage of L-Citrulline in sports supplementation is its ability to transform into L-Arginine, which acts as a direct precursor to Nitric Oxide (NO). This increase in NO causes vasodilation, improving blood flow to the muscles. As a result, the delivery of oxygen and nutrients is optimized, which not only enhances performance during exercise but also helps delay fatigue and generates a significant muscle "pump" effect. It is primarily aimed at endurance and strength athletes, promoting efficient circulation and accelerating muscle recovery. To ensure maximum benefit, it is recommended to take it 30 to 60 minutes before training. The product contains ingredients such as L-Citrulline, microcrystalline cellulose, magnesium stearate, and gelatin in its capsule, ensuring both efficacy and quality in its formulation.
