L-Citrulline 3000mg Powder provides a pure, unflavored amino acid that the body converts to L-Arginine. This increases nitric oxide production, supporting healthy blood flow and cardiovascular function. Each serving is ideal for pre-workout performance and post-exercise recovery. L-Citrulline is more effective than L-Arginine at raising plasma arginine levels. A clean, versatile powder for men's performance and cardiovascular health support.
