Use a commercial electrolyte powder or tablet

Add a dissolvable electrolyte tablet or powder sachet to your water bottle for enhanced hydration during exercise, travel, or hot weather. Products like Nuun, Liquid IV, and LMNT provide calibrated doses of sodium, potassium, and magnesium without excess sugar.

Why It Works

Electrolyte supplements replace minerals lost through sweat and enhance water absorption in the small intestine. Clinical formulations based on oral rehydration science deliver sodium and glucose in ratios that maximize fluid uptake — up to 2-3 times faster than plain water according to the osmolarity research behind the WHO's rehydration protocol.

Tips

• Nuun Sport (~$7 for 10 tablets) is low-calorie and effervescent — good for daily use
• Liquid IV (~$1.50/packet) uses Cellular Transport Technology for rapid absorption — better for recovery
• LMNT (~$2/packet) is sugar-free with high sodium — designed for keto, fasting, or heavy sweaters
• Read labels: some products contain high sugar (up to 30g per serving), which can cause GI discomfort
• Not necessary for light activity or sedentary days — plain water is sufficient for routine hydration
