The Active Ingredient Is: Magnesium (Citrate Form)

Magnesium is a key mineral that helps everyday muscle function and energy metabolism. This form is magnesium citrate, a highly bioavailable source used to help balance minerals in the body during activity.

Magnesium citrate helps balance electrolytes and is part of the mineral mix included to support normal bodily processes during exercise.

What Does Magnesium (Citrate Form) Do?

Magnesium takes part in muscle function and helps keep electrolyte balance, supporting normal muscle contraction during activity. EFSA recognises minerals generally as playing a role in these normal physiological functions. [This is part of how your body keeps moving.]

In hydration and endurance settings, isotonic drinks with minerals like magnesium help maintain hydration and performance, as noted by researchers at a major university. [What’s more, these notes come from respected sources.]
