Pure Nutrition L Arginine Capsule 60 is used for supporting blood circulation and heart health. It is formulated to help enhance blood flow, improve heart health, and support muscle performance. The supplement contains a powerful blend of L-arginine, L-citrulline, beetroot extract, and caffeine. Together, these ingredients help dilate blood vessels, increase endurance, and provide a stronger pump during exercise. L-arginine helps produce nitric oxide, which dilates blood vessels, allowing better oxygen and nutrient delivery to the muscles. This, in turn, promotes improved muscle recovery and performance, especially during physical activity.
