Hydration / electrolytes
Essentials · Lifestyle
Tier A+
Bottom line
Read Off Label grades Hydration / electrolytes as A+ (8.4/10) based on strong evidence, high benefit magnitude, and a low-risk safety profile.
Chronic under-hydration linked to increased biological aging markers.
Typical use: ~2. — N/A.
What this is
Chronic under-hydration linked to increased biological aging markers. Endurance athletes need deliberate electrolyte intake.
Mechanism
Maintains blood volume, thermoregulation, cellular function; sodium/potassium/magnesium required for nerve and muscle function
Dose & route
~2.5-3.5L total water/day (varies by size, climate, activity); sodium 3-5g/day for active people
