Hydration evidence brief
Electrolyte products replace sodium and other minerals lost through sweat. They are mainly useful for long, hot, or high-sweat sessions rather than ordinary short workouts.
Useful for long, hot, high-sweat sessions and rehydration, but unnecessary for many short indoor workouts.
Hydration meta-analysis: hypotonic carbohydrate-electrolyte drinks best preserved plasma-volume status during exercise.
Match sodium and fluid intake to sweat rate, heat, session duration, and gut tolerance.
Overhydration is a real risk. Electrolytes are not a general energy, pump, or physique-change supplement.

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
