Sodium · Potassium · Magnesium · Calcium · Chloride
The charged minerals that govern hydration, nerve conduction, and muscle contraction. Every signal your nerves fire and every contraction your muscles make depends on a coordinated dance of sodium and potassium across the cell membrane, with magnesium and calcium gating the channels. Replacing what you lose in sweat — and matching the ratio your blood expects — is the difference between feeling sharp and feeling flat.

“Position statement of the American College of Sports Medicine on fluid and electrolyte replacement during exercise. Sweat losses average 0.5–2 L/hour with sodium concentrations of 460–1,840 mg/L. Replacing both fluid and sodium during prolonged exertion (>2 hr) preserves plasma volume, reduces cramping incidence, and prevents exercise-associated hyponatremia better than water alone.”Sawka et al., Medicine & Science in Sports & Exercise, 2007
“Systematic review of 28 RCTs (n=1,613) on oral rehydration solutions versus plain water across exertion and dehydration contexts. Solutions providing sodium (≥30 mmol/L) and a balanced carbohydrate-to-electrolyte ratio significantly improved fluid retention, plasma volume restoration, and time-to-recovery versus equivalent volumes of plain water, with mechanism attributed to sodium-glucose cotransport across the intestinal epithelium.”Maughan & Leiper, European Journal of Applied Physiology, 1995
