The amino acid arginine is a known nitric-oxide booster – it’s readily converted to NO in the body. NO helps expand blood vessels, allowing more blood flow to skeletal muscles for improved delivery of oxygen, anabolic hormones and nutrients such as amino acids. This accelerates muscle recovery and growth in response to training. In fact, research has found the arginine supplementation may reduce body fat while increasing muscle mass. Preliminary findings from a study conducted at the University of Athens Medical School in Greece suggests that when Vitamin C is taken with a arginine supplement, it results in noticeably greater levels of NO than arginine taken alone. Vitamin C functions as an antioxidant, which may protect NO from degradation by free radicals.
Before a workout, take your arginine supplement with a protein shake that includes fresh or frozen strawberries – they have more Vitamin C that other common berries, such as blueberries or raspberries.
