NutraBio L-Citrulline delivers pure, fermented citrulline to drive blood flow, endurance, and muscular pump without stimulants or fillers. It’s built for athletes who want direct performance support — clean, stackable, and effective.
Each scoop provides 2 grams of fermented L-Citrulline to support nitric oxide production, improving oxygen delivery and nutrient transport during training. Increased circulation helps extend work capacity, sharpen muscle fullness, and maintain stronger output set after set. Because it’s fermented, this citrulline is easier to digest and absorbs efficiently — making it ideal to stack with pre-workouts, creatine, electrolytes, or intra-workout formulas. This is pump support the right way: simple, effective, and purpose-driven.
