L-citrulline has quickly become a hit in hundreds of supplements, from pre-workouts to recovery blends. Even though it’s popular, many users still don’t know exactly what it does.
We’re here to clear up some confusion and set the record straight about this incredible amino acid that boosts energy, decreases fatigue, and improves blood flow.
What Is L-Citrulline?
L-citrulline is a non-essential amino acid. With amino acids, non-essential simply means that the body can create small amounts from other compounds; essential amino acids have to come from the diet.
While we usually associate amino acids with protein, L-citrulline is one of the few non-protein amino acids. Instead of being used for just building muscle tissue, it contributes to a variety of functions.
Many people take L-citrulline supplements, but you can also get it from foods, mainly watermelon, cucumbers, and some varieties of squash.
