The Active Ingredient Is: Potassium

Potassium is an essential mineral that helps support normal fluid balance and muscle function. It is a key part of the five-electrolyte blend in this product, contributing to overall hydration and performance during activity.

This formula includes potassium as part of a broader electrolyte system designed to replenish minerals lost through sweat, with additional components that aid in maintaining electrolyte equilibrium and supporting athletic recovery.

What Does Potassium Do?

Potassium plays a role in maintaining normal body fluid balance and in supporting neuromuscular function during exercise. These functions are in line with guidance from health authorities on electrolyte nutrition and hydration.

By contributing to electrolyte balance, potassium helps support sustained focus and muscle performance during intense activity, alongside the product’s other electrolytes and performance ingredients.
