Best L-Citrulline

Citrulline is a nonessential amino acid, meaning your body can produce it naturally. However, you can increase citrulline levels by eating foods containing citrulline or by taking an L-citrulline supplement. (See Reference 1)

Having L-citrulline in your body evidences many benefits:

Health Benefitrs of L-Citrulline

Cardiovascular Health

One study of patients with heart failure found that L-citrulline increased blood volume from the right ventricle of the heart. (See Reference 2) L-citrulline was also able to lower blood pressure in the pulmonary artery. (See Reference 2) Another study found that L-citrulline improved the function of both the left and right ventricles, as well as improving endothelial function. (See Reference 3) (See Reference 5)

Exercise Performance

L-Citrulline has been shown to benefit exercise performance in a number of ways. (See Reference 6) One of these benefits is an increase in exercise capacity. (See Reference 8) One study involving heart failure patients found that supplementing with L-citrulline allowed them to exercise on a treadmill for longer. (See Reference 9) Another study involving trained cyclists found that L-citrulline helped the cyclists complete a 4km time trial more quickly. (See Reference 4)

L-citrulline has also been shown to increase levels of adenosine triphosphate (ATP) stored in the body. ATP is strongly associated with increased anaerobic exercise performance. (See Reference 10)

A variant of L-citrulline known as L-citrulline malate has also been shown to help with exercise performance. L-citrulline malate is the combination of citrulline and malate, a compound which increases energy production. (See Reference 11) Malate is a salt of malic acid, which binds to citrulline and gives it stability within the body.

Several studies have shown L-Citrulline malate is beneficial for weight training performance. (See Reference 12) In one study, a group of men were assessed on upper body exercises to see whether L-Citrulline malate had any effect on their performance. (See Reference 14)

  • Men using L-Citrulline malate performed 53% more repetitions, as compared to the placebo group
  • Muscle soreness was 40% lower in the men who used L-Citrulline malate prior to weight training

Fatigue

One study of young men suffering from general fatigue showed improvement of their symptoms after supplementing with L-citrulline. (See Reference 7) L-citrulline helped to reduce post-exercise fatigue, as well as increase the young men’s ATP (energy) levels during exercise. Other research has confirmed this study’s results, showing that l-citrulline helps to reduce exercise-induced fatigue in healthy people.

Growth Hormone

A double-blind, randomized controlled trial on a small group of cyclists found that L-citrulline increased growth hormone (GH) after exercise. (See Reference 13) Researchers concluded that this increase is probably due to the increase in arginine, which has been shown to decrease a hormone which inhibits GH production. A post-exercise increase in GH could help to increase beneficial post-exercise adaptations.

Immunity

A double-blind, randomized controlled trial carried out on male cyclists found that the function of neutrophils improved in men supplementing with L-citrulline. (See Reference 15) Neutrophils are a type of white blood cell that helps to fight infection.
