L-citrulline is an amino acid known for being a precursor of L-arginine.
Some authors claim that a more efficient method of maintaining arginine levels in the body is obtained precisely after the use of a precursor.
L-citrulline is one of the three amino acids in the urea cycle, along with L-arginine and L-ornithine.
When taken additionally it increases the content of ornithine and arginine in the plasma.
This in turn leads to an effective removal of ammonia from the body.
Benefits of intake:
- improves cardiovascular activity
- reduces fatigue during physical exertion
- increases endurance
- helps blood circulation
- reduces blood pressure
Because the amino acid in question is more easily absorbed than L-arginine, which is rapidly broken down in the liver before reaching the liver, L-citrulline is a far more efficient way to increase arginine levels in the liver.
One study in cardiac patients found that 3 grams of citrulline (like citrulline malate) was equivalent to a dose of 6 grams of arginine, suggesting that precursor may have twice the potency.
- 5 to 8 grams, one hour before workout.
