Can coconut water replenish electrolytes?

Yes, some: Coconut water has less sugar and sodium and more potassium than Gatorade. It will replenish electrolytes (sodium and potassium) but the amount replenished will be different than Gatorade. Some athletes use coconut water, but, to get the proper ratio of electrolytes you need to add sodium (i.e. table salt). It may be easier to stick with the low sugar versions of Gatorade.

Potassium: Coconut water is high in potassium but not enough sodium. Can add salt if possible, does have sugar and the fluids. Electrolyte replacement solutions are available too and can chose a low sugar content prep.
