The Active Ingredient Is: L-Citrulline

L-Citrulline is a naturally occurring amino acid that helps fuel the body’s nitric oxide production, supporting better blood flow during workouts. This form is a free form amino acid often used in pre-workout mixes to boost exercise performance and endurance via improved circulation.

What Does L-Citrulline Do?

L-Citrulline joins nitric oxide pathways to help promote steadier blood flow and longer-lasting energy during activity. It supports muscular endurance and performance, in line with evidence on nitric oxide mechanisms at play in exercise.
