The Active Ingredient Is: Taurine

Taurine is an amino acid-like compound present in many energy- and hydration-focused formulations.

This formula features taurine alongside other amino acids, which together contribute to amino acid availability in the body to support normal physiological processes during activity.

What Does Taurine Do?

Amino acids participate in supporting muscle recovery and normal energy-related function after exercise, within the body’s usual metabolic processes.

This combination also includes electrolytes that help maintain fluid balance and support hydration during activity, in line with standard physiological function for exercising individuals.
