Coconut water
Coconut water is a popular choice among athletes trying to naturally rehydrate and replace electrolytes, and for good reason. It's high in electrolytes, with calcium, potassium, salt, magnesium, and phosphorus - all of which may aid reduce muscular cramps.
When 10 male athletes rehydrated with an electrolyte-containing beverage comparable to coconut water after intensive exercise, they were less sensitive to electrical-stimulation-induced muscular cramps than when they hydrated with ordinary water, according to one research. More study is needed to determine whether staying hydrated with electrolyte-rich coconut water will help lessen your susceptibility to post-exercise muscular cramping.
