Hydration benefits

Physical Performance

Hydration with electrolytes, particularly sodium and potassium has been found to aid performance during prolonged exercise. Studies suggest that staying hydrated is key for performance in strength, power, and high-intensity endurance based exercise, as well as managing thermoregulation mechanisms.

Cognitive Function

Adequate hydration with magnesium is linked to maintenance of normal brain function. Studies show that increased brain magnesium may improve brain activity, influencing nerve signal transmission and preserving blood-brain barrier integrity, which can affect cognitive functions such as memory and attention.

Muscular Recovery

Electrolytes, especially magnesium, may play a significant role in post-exercise recovery. Studies have shown that magnesium supplementation may significantly reduce muscle soreness, session rating of perceived exertion, acute rating of perceived exertion, and improve perceived recovery.
