Definition
Citrulline malate increases nitric oxide production, which dilates blood vessels and improves nutrient delivery to working muscles. The malate component also buffers fatigue. Studies show 6–8g of citrulline malate 30–60 minutes before training improves rep performance and reduces soreness. It's one of the most evidence backed pre workout ingredients.
