Weider Arginine + Ornithine 4000 – 180 Capsules

is a premium amino acid supplement formulated to support nitric oxide production, muscle pumps, endurance, and post-workout recovery. Each serving delivers 2500mg of L-Arginine and 1500mg of L-Ornithine, two synergistic amino acids that help promote healthy blood flow, enhance nutrient delivery to working muscles, and support intense training performance.

L-Arginine serves as a precursor to nitric oxide (NO), helping improve vascularity and muscle pumps during workouts, while L-Ornithine complements arginine metabolism and contributes to improved recovery and exercise performance. This high-potency formula is ideal for athletes, bodybuilders, and fitness enthusiasts seeking enhanced endurance, better training capacity, and improved muscle support. The convenient capsule format makes it easy to take approximately 30–45 minutes before training or as part of your daily supplementation routine.
