re ‘salt’- the electrolyte mixes in drinks etc can be more than just sodium chloride (two electrolytes)..
example torq includes Sodium Chloride, Magnesium, Potassium and Calcium (assuming not in their pure forms!)
the myprotein electrolyte mix contains:
Sodium Chloride, Potassium Sulphate, Calcium Di Phosphate, Magnesium Oxide.
not sure whether these electrolytes work, but i found that using a drink without in the hot summer led to more headaches, feeling tired etc
as for the OP, i mix from big bags frustose and maltodextrin + electrolytes from myprotein with dash of squash for taste
