Arginine is one of the amino acids that is produced by the pituitary gland, which means that it is not an essential nutrient. However, when the demand is higher than usual, the body may not produce the necessary amount of arginine. Therefore, it may be necessary to take it as a dietary supplement. Arginine plays an important role in the synthesis of nitric oxide, also known as nitric oxide (NO). Main benefits: Muscle mass increase Better recovery between workouts Encourages nitric oxide production and keeps blood vessels dilated for better blood flow Dosage: Take 2.5-5g (1-2 scoops) half an hour before training in 200ml of water.
