MAXIMIZE
RECOVERY

Maximizing recovery while you sleep is essential because that’s when your body repairs muscles, calms the nervous system, and restores energy. Magnesium supports this process by promoting relaxation, improving sleep quality, and helping muscles and nerves recover more efficiently - so you wake up feeling restored, not just rested.
