Nutricost L-Citrulline Powder is a pure, non-essential amino acid supplement that serves as a high-efficiency precursor to L-Arginine. Clinically, L-Citrulline is recognized for its superior ability to bypass first-pass hepatic metabolism, resulting in higher sustained plasma Arginine levels and prolonged Nitric Oxide (NO) production compared to direct Arginine supplementation.

• Optimized Vasodilation: Enhances systemic blood flow and microcirculation by relaxing vascular smooth muscle, facilitating improved oxygen and nutrient delivery to peripheral tissues.
• Endurance & Recovery: Accelerates the clearance of metabolic secondary metabolites, such as ammonia and lactic acid, via the urea cycle, thereby delaying the onset of muscular fatigue.
• Superior Bioavailability: Unlike L-Arginine, L-Citrulline is not a substrate for the enzyme arginase in the gut, ensuring a higher percentage of the dose reaching the systemic circulation.
• Pure Ingredient Profile: Provides a massive 3,000 mg of pure L-Citrulline per serving. The unflavored format is free from artificial sweeteners, colors, and excipients, making it ideal for "stacking" with other pre-workout compounds.
• High-Volume Format: The 600g container offers 200 servings, providing an industry-leading cost-per-dose for long-term cardiovascular and athletic support.

Recommended Usage: Mix one (1) scoop (approx. 3g) with 8–12 oz of water or your preferred beverage. For maximum ergogenic benefit, consume 30–60 minutes prior to physical activity. It may also be taken in divided doses throughout the day to support chronic vascular health.
