Electrolyte Overload: The 6 Common Sports Drinks Quietly Harming Your Kidneys

3. BodyArmor: Coconut Water and Potassium Pitfalls

BodyArmor differentiates itself in the sports drink aisle by using coconut water—a natural source of potassium—as its base. The appeal of “natural” electrolytes has fueled BodyArmor’s rise, but it also brings a hidden hazard for anyone with vulnerable kidneys. Coconut water, while hydrating for many, is surprisingly high in potassium, which can be especially dangerous for those managing kidney conditions or following a restricted diet.

4. Vitaminwater: Electrolytes with Sneaky Additives

Vitaminwater positions itself as the “healthy” alternative to soda—a splash of vitamins, a handful of electrolytes, and sweet flavors that make plain water seem almost dull. This reputation has made it a popular choice for people aiming to hydrate smarter. But beneath the friendly label, many Vitaminwater varieties deliver more than hydration: added sugars, sodium, and sometimes phosphate-based ingredients that can add stress to aging or vulnerable kidneys.
