The Active Ingredient Is: Citrulline Malate

Citrulline malate is an amino acid–based compound that helps with metabolic processes linked to muscle function and endurance during workouts.

This blend teams citrulline with malate, a piece that helps with energy production and better nutrient delivery to your muscles.

What Does Citrulline Malate Do?

Citrulline malate helps boost blood flow and nitric oxide, which can lift your muscle endurance and push fatigue away during workouts, based on studies from a university lab. This lines up with general guidance on how blood flow and performance work.

Evidence points to this pairing helping maintain performance by boosting oxygen and nutrients to active muscles.
