Sodium Deficit800 mg
Potassium Deficit2,200 mg
Magnesium Deficit200 mg
Overall Electrolyte Gap %44%
What is it?
Identifies electrolyte deficits by comparing your actual dietary intake to RDA targets for sodium, potassium, and magnesium.
How to use
Enter your target and actual daily intake for each electrolyte. The overall gap score shows your average deficiency across all three.
Example scenario
With typical dietary intakes of 1500mg sodium, 2500mg potassium, and 200mg magnesium, the overall gap score is ~46% — significant deficiency.
Pro tip
Potassium is the most commonly deficient mineral. Avocados, bananas, and leafy greens are excellent sources.
