L-Citrulline vs Citrulline Malate: Which is the Better Nitric Oxide Booster?

Citrulline is a non-essential amino acid that our body naturally produces on its own. It is one of the top pre-workout supplements that is used to boost muscle pumps and improve the muscle-mind connection. It also promotes blood flow during workout which speed up recovery and delivery of nutrients.

Citrulline also has an essential role in the urea cycle which helps your body to get rid of harmful substances like ammonia.

Although there are various types of Citrulline found in the market, this article will mainly focus on L-Citrulline and Citrulline Malate and which is the best nitric oxide booster.

Let's dive in and find out what L-Citrulline and Citrulline Malate are and which is best.

What is L-Citrulline?

L-Citrulline is a naturally occurring and non-essential amino acid that is found in some foods like watermelon as well as our body produces these amino acids by itself. Our body converts L-citrulline into another amino acid called L-arginine and nitric oxide.

L citrulline is pure citrulline used for muscle weakness, Alzheimer's disease, dementia, high blood pressure, fatigue, sickle cell disease, and diabetes. It is also used for bodybuilding, improving athletic performance, increasing energy, and heart disease.

How does it work?

Your body converts L-Citrulline into nitric oxide, thereby increasing the number of nitric oxide in your body. Nitric oxide helps open up arteries and veins and improve blood flow in blood vessels so the blood travels more smoothly and efficiently to your muscles and other tissues that need energy. It also helps increase the supply of ingredients the body needs to make certain proteins.

Studies show that L-Citrulline boosts muscle protein level, build muscle, and improve athletic performance.

What is Citrulline Malate?

Citrulline Malate is a combination of L-Citrulline and Malate, which derives from malic acid. It is a direct precursor to nitric oxide. Research has shown that citrulline malate could have a bigger effect because it potentially increases the production of ATP. Other studies reveal that citrulline malate is beneficial for muscle strength and endurance.

How does it work?

Our body converts Citrulline malate into two other compounds named ornithine and arginine, and from there, it is converted into nitric oxide. Higher ornithine and arginine improve nitric oxide metabolism and increase nitric oxide count. Nitric oxide is a vasodilator that allows more oxygen, blood flow, and nutrients to be transported into the muscle tissue.

Which one is the better nitric oxide booster?

In general, both L-citrulline and are Citrulline Malate effective at increasing nitric oxide production, but the best option for you may depend on your specific needs and goals. If you are looking primarily to increase your nitric acid performance, L-Citrulline may be the better choice. However, if you are interested in improving exercise performance, reducing fatigue, and boosting nitric oxide, Citrulline Malate may be a more comprehensive option.

Taking L-Citrulline may benefit your workout by enhancing your endurance. Researchers found that L-Citrulline could boost your performance and help you recover faster.

While Citrulline Malate helps boost both aerobic and anaerobic activity as well as help increase muscular energy. It also enables you to improve strength, power, and muscular pumps, as well as reduce fatigue and muscle soreness, after training.

It also enhances blood flow and amino acid uptake to the skeletal muscle, promoting muscle growth and greater protein synthesis.

L-Citrulline helps improve your heart health and blood vessel health. It is also helpful to boost your immune system. It is used to increase blood flow for different training and recovery purposes and improve blood flow to your muscle. It is also used to utilize oxygen during your workout. Other benefits include improved muscular energy and enhanced performance, endurance, and lean muscle.

Customer reviews


“I have tried many, many pre-workouts, and this one is among my very favorite. If not, MY FAVORITE of all time. I was also excited to try out Mesomorph, and its new flavor, but the ingredients, although give me energy, leave me feeling incredibly sick, upset to my stomach and tingly in the head. Wild Thing gives me all the energy, pump, and focus I need and doesn't compromise me with lasting negative side effects. This is a win, and my new go-to pre workout.”
