Coconut water
A naturally hydrating drink with useful potassium; check the label for added sugar versions.
Why it received this rating
Plain coconut water provides fluid, potassium, and naturally occurring carbohydrate. The yellow rating reflects that it is not interchangeable with water or every electrolyte product: sodium is relatively limited and sweetened versions can contain more sugar.

Portion and preparation guidance
One cup (about 8 fl oz) is a standard serving. It can be a reasonable alternative to a sports drink when fluids are low, though it carries less sodium than dedicated electrolyte products.
Symptoms or considerations
Check the label for serving size, potassium, sodium, and added sugar. If you have kidney disease or take medicines that affect potassium, ask your clinician whether high-potassium drinks fit your care plan.
Common questions
Is coconut water a good hydration choice on a GLP-1?
For some people, plain unsweetened coconut water is a reasonable option: it provides fluid, potassium, and modest natural sugar. It has less sodium than a dedicated electrolyte drink, so during active vomiting or diarrhea, a low-sugar electrolyte product may replace lost sodium more directly.
What's the difference between coconut water and coconut beverages?
Plain coconut water is the liquid from young coconuts with no added sugar. Sweetened coconut beverages, coconut milk drinks, or coconut water blends with juice can carry considerably more sugar per serving. The nutrition label, specifically the sugar line, is the fastest way to tell them apart.
