Saltus is the electrolyte tracker that adapts to how you live โ€” whether you're an endurance athlete, managing POTS, doing keto, or fasting. Track sodium, potassium, magnesium, and water against daily targets built for your needs, not generic water goals. CHOOSE YOUR MODE - Athlete โ€” sweat-rate and training-aware targets, heat-adjusted dosing, race-day planning - POTS โ€” higher daily sodium guidance, as often advised by clinicians for managing symptoms - Keto โ€” electrolyte replacement targets for low-carb living - Fasting โ€” steady mineral targets through your fasting windows WHY SALTUS Generic water trackers don't tell you about sodium, potassium, or magnesium.

Marathon runners, cyclists, triathletes, people managing dysautonomia, and low-carb and fasting communities all use Saltus to stay on top of sodium, potassium, and magnesium.
