Electrolyte / Salt Capsules

Performance · Evidence: Moderate · Importance: Moderate

Concentrated sodium (and often potassium/magnesium) to replace electrolytes lost in sweat during long or hot training.

Educational only — not medical advice. BodEvo summarizes research cautiously and labels estimates as estimates. Talk to a physician or registered dietitian before starting any supplement, diet, or training program.

What the evidence says

Well supported for endurance/hot-weather performance and cramping risk when sweat sodium losses are high; little benefit for short, low-intensity sessions.

Typical dose & timing

Dose: Dose to sweat/sodium losses; many endurance athletes target ~300–700 mg sodium per hour of hard, sweaty exercise. Individualize.

Timing: Around and during prolonged or hot sessions, with fluids.

Role in a stack

Hydration/performance support for endurance and heavy-sweat contexts; unnecessary for short, low-sweat workouts.

Redundancy check: Overlaps with electrolyte drink mixes — don’t double up. Plain table salt + water is a cheap equivalent.

Cautions & safety

Most people get enough sodium from food. Excess sodium is a concern for those with high blood pressure or kidney issues — check with a clinician.

Match intake to actual sweat losses and fluid intake. Educational only — those with hypertension or kidney conditions should consult a clinician.

Best for

endurance sessions · heavy sweaters · hot-weather training · high-volume conditioning
