The Active Ingredient Is: Octacosanol

Octacosanol is shown as the main active compound in this formula, with its source clearly tied to sugar cane as a raw material used in its manufacturing.
What Does Octacosanol Do?
Octacosanol could help bolster endurance and energy during workouts by shaping how energy is produced in cells and how oxygen is used during exertion. It also shows mild antioxidant effects that can support tissues under physical strain.
Dr. Kato from the University of Tokyo found that octacosanol enhances oxygen utilisation in skeletal muscles during aerobic activity, which can help improve exercise tolerance.
