Where each one actually wins
Stay with Dr Hydrate if
you want an all-in-one supplement-style hydration formula containing electrolytes plus amino acids, vitamins and other added nutrients, rather than a focused electrolyte formula.
you don't eat enough protein or supplement with protein and want extra amino acids for muscular recovery.
you don't mind artificial sweeteners and magnesium citrate.
you prefer the option of a tub and scoop to use.
Switch to Purelyte if
your priority is a simpler electrolyte-focused formula with substantially more sodium and potassium, no sucralose.
you already supplement with protein or have a high protein diet.
you want all natural ingredients.
