The Active Ingredient Is: Creatine

Creatine is a everyday compound used for quick energy bursts in muscles, helping short sprints of intense effort.

This formula helps keep energy ready for repeated efforts during training and competition, and the formulation includes electrolytes and other nutrients that aid energy metabolism and endurance performance.

What Does Creatine Do?

Creatine helps restore adenosine triphosphate, which keeps power output steady during repeated high-intensity exercise.

Research suggests a daily intake of creatine supports strength and power in short, intense efforts, which aligns with EFSA and NHS-style summaries.

The main benefit is backed by evidence from Dr. Kreider at the University of Memphis, showing improved performance with creatine-containing regimens in endurance and high-intensity contexts.
