What L-citrulline is
L-citrulline is an amino acid that the body makes on its own. It takes its name from Citrullus, the Latin name for watermelon, where it was first identified. It is not one of the amino acids used to build protein, and it is the compound the body turns into L-arginine.
Each tablet holds 1000 mg of L-citrulline, listed on the licence as coming from citrulline malate. Natural Factors makes it through bacterial fermentation and describes the formula as vegan and non-GMO. The tablet base is carbohydrate gum, cellulose, dicalcium phosphate dihydrate, glycerin, hydroxypropyl cellulose, magnesium stearate, silica and stearic acid.
