The Active Ingredient Is: Citrulline Malate (2:1)

Citrulline malate is a combo that teams the amino acid citrulline with malic acid, and helps boost nitric oxide production for better blood flow and muscle pumps during workouts.

This form is often picked for its 2:1 citrulline to malate ratio, recognised for helping energy availability and endurance during training.

What Does Citrulline Malate Do?

Citrulline malate helps with normal vascular function by supporting flows that aid blood delivery and nutrients during tough sessions. It’s involved in pathways that contribute to steady performance and recovery, as EFSA guidelines note.

Dr. Bailey at University College London found that higher citrulline intake links to better endurance during tough, high‑intensity efforts.
