I presume these do what they are meant to do...replenish electrolytes (although how completely you need replenishing, meaning needing other minerals besides what are in these Idk) However, the whole reason I would not repurchase is the taste is ...OFF. For some its not that strong, but for me its TOO strong, I want a subtler lemon lime taste (or any other flavor) basically a sugarless Sprite taste. And if you're looking for fizz to truly make it a flavored seltzer water experience, Nope.
