Sodium belongs with sweat
An electrolyte replaces what left in sweat. The useful line is the milligrams.
Sodium is the main mineral lost in sweat. A useful sachet tells you the milligrams of sodium in one serving, then potassium and magnesium on their own lines. A vague mix does not tell you whether the drink matches the session.
A short easy day and a long hot session do not need the same amount. If you barely sweated, you may not need a sachet. If the session was long and hot, the milligrams are the reason to drink it.
On our sachet the lines are 340 mg of sodium, 160 mg of potassium, and 40 mg of magnesium. Those three numbers are the drink.
