Electrolytes
For long, hot, sweaty sessions — not something a normal gym workout requires.
Sodium, potassium, magnesium and chloride — the minerals lost in sweat that keep hydration and muscle function working.
Genuinely useful when you sweat heavily for a long time — hot-weather endurance, long rides, back-to-back training. For a 45-minute indoor session, water and a normal diet cover it; you don't need the sachet.
- !Most sports drinks are electrolytes plus a lot of sugar — read the label if you're watching calories.
- !If you're on a low-sodium diet for medical reasons, check with your doctor first.
Note:General information, not medical advice. Supplements interact with medications and conditions — check with your doctor before starting anything, especially if you're pregnant, nursing or managing a health condition.
