If you prefer to source your own electrolytes instead buying LMNT, jot this down and grab a kitchen scale:

2,500 mg sodium chloride (for 1,000 mg sodium)

385 mg potassium chloride (for 200 mg potassium)

390 mg magnesium malate OR 265 mg di-magnesium malate (for 60 mg magnesium)

LMNT shares recipes for four flavors of their electrolytes.
