1. Improved hydration: As the name suggests, the product is designed to keep the body well-hydrated. This can benefit overall health by preventing dehydration, which can cause fatigue, headaches, and other health issues.

The Active Ingredient Is: Magnesium

Magnesium is an essential mineral involved in many normal bodily functions and acts as a key electrolyte in cellular activities.

This formulation provides magnesium in an ionic, bioavailable form derived from isotonic electrolytes in marine plasma to support hydration and electrolyte balance during sleep.

What Does Magnesium Do?

Magnesium helps maintain normal muscle and nerve function and contributes to electrolyte balance, which supports hydration status in alignment with EFSA guidance.

Within the product context, magnesium may contribute to overnight cellular processes related to relaxation and recovery, aligning with sleep-support nutrition concepts discussed in the broader literature.
