Coconut water became a health trend for good reasons: it's hydrating, contains electrolytes (potassium, magnesium), and is naturally low in sugar compared to most fruit juices. 17 mg oxalate per serving — safely in the green zone. For kidney stone patients, coconut water is one of the better beverage choices. The potassium content is a bonus. Just don't buy the versions with added sugar — plain coconut water is what you want. During hot weather when stone risk peaks, coconut water is a solid hydrator.
