L-Citrulline is an non-essential amino acid involved in producing nitric oxide, supporting usual blood flow and nutrient delivery during workouts.

This format is shown as the free amino acid L-Citrulline and is typically sourced as a purified supplement ingredient to aid vascular function during exercise.

What Does L-Citrulline Do?

L-Citrulline participates in making nitric oxide, which can help sustain normal vessel dilation and flow during workouts. Scientific studies suggest boosted endurance and support for muscle oxygen delivery, aligning with EFSA guidance on nutrient function.

Dr. Suzuki from Osaka University noted that L-Citrulline supplementation may support endurance performance by boosting blood flow and nutrient transport during physical activity.
