Salt substitute preparations containing potassium chloride are commonly available for those who want a clear fluid. Orange juice and tomato juice are far more concentrated sources of potassium, sodium and chlorides than any of the patented drinks, or ors packets. The natural juices have a bit more sugar than needed, remedied by dilution.
