L-Arginine

What Is L-Citrulline?

L-Citrulline is a naturally occurring amino acid involved in the body’s urea cycle and in the production of L-Arginine. L-Citrulline is also associated with the body’s nitric oxide pathway, making it a popular ingredient in sports nutrition and performance-focused formulations.

Commercial L-Citrulline is commonly supplied as a powder and can be used in a variety of finished-product formats.

For manufacturers and formulators, L-Citrulline can be used as a standalone ingredient or combined with other amino acids, creatine, vitamins, minerals, and functional ingredients depending on the intended application.

L-Citrulline & Sports Nutrition

L-Citrulline is a popular ingredient in sports nutrition formulations because of its role in the body’s nitric oxide and arginine pathways.

It is commonly included in pre-workout and performance-oriented products developed for athletes, fitness enthusiasts, and active-lifestyle consumers.

Formulators can incorporate L-Citrulline into standalone products or combine it with complementary ingredients to develop multi-ingredient sports nutrition formulas.

L-Citrulline vs. L-Arginine

L-Citrulline and L-Arginine are closely related amino acids involved in the nitric oxide pathway.

L-Citrulline can be converted by the body into L-Arginine, making it a commonly used ingredient for formulations designed around arginine and nitric oxide support.

Both ingredients can be used individually or together depending on the formulation concept, target product, and desired ingredient profile.
