The alternatives, ranked
How to choose
If you liked Waterboy’s clean single-purpose sodium hit but want more potassium and magnesium for the money, Earth Energy and LMNT both deliver a fuller profile at a lower per-milligram cost. If the format and simplicity were the draw, Waterboy is fine — just know you’re paying a premium for a lighter mineral profile. The full field is in our comparison.
