The Active Ingredient Is: Creatine

Creatine is a naturally occurring compound that helps supply energy for quick, high-intensity activities.

This blend contains creatine to help maintain energy availability and performance through intense workouts, matching its role in energy replenishment and muscle action.

What Does Creatine Do?

Creatine helps out in ATP regeneration, which aids short bursts of muscle effort and general stamina while you work out.

EFSA notes that the process includes fast energy generation and keeping up muscle energy reserves, helping with steady physical performance in high-intensity settings.
