How Electrolyte Calculator is Calculated

Frequently Asked Questions

Why do I need to worry about electrolytes?

Electrolyte imbalance causes muscle cramps, fatigue, headaches, and poor performance. Active individuals lose 1–2g sodium per hour through sweat. Low-carb diets flush electrolytes rapidly in the first weeks.

How much sodium do athletes need?

Endurance athletes: 1,000–1,500 mg sodium per hour of exercise. Daily total: 3,000–5,000 mg for active individuals (vs. 2,300 mg RDA for sedentary adults). Add ¼ tsp salt to water during intense workouts.
