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

L-Citrulline Malate is a semi-essential amino acid derivative used to help support everyday physiological processes involved in blood flow and exercise performance.

This form links citrulline with malate, a compound that helps energy production during activity and is commonly used to support nitric oxide driven processes.

What Does L-Citrulline Malate Do?

L-Citrulline Malate helps participate in nitric oxide production, which helps boost blood flow and a muscular pump during exercise. This supports performance related functions as described in clinical evidence and EFSA aligned summaries.

Dr. Gonzalez from the University found that L-Citrulline Malate noticeably increases repetition performance and enhances the pump in weight training.
