4. May Help Prevent Kidney Stones
Drinking enough fluids is important for kidney stone prevention.
Although plain water is a great choice, one study suggests that coconut water may be even better.
Kidney stones form when calcium, oxalate and other compounds combine to form crystals in your urine (13).
These can then form stones. However, some people are more susceptible to developing them than others (13).
In a study in rats with kidney stones, coconut water prevented crystals from sticking to the kidneys and other parts of the urinary tract. It also reduced the number of crystals formed in the urine (14).
Researchers believe that coconut water helped reduce free radical production that occurred in response to high oxalate levels in urine.
Keep in mind that this is the first study examining coconut water’s effects on kidney stones. More research is needed in this area.
Early animal research suggests that water from coconuts may prevent kidney stones by reducing crystal and stone formation.
5. May Support Heart Health
Drinking coconut water may be helpful to reduce heart disease risk.
In one study, rats that consumed coconut water had reductions in blood cholesterol and triglycerides. They also experienced significant decreases in liver fat (15).
In another study, the same researchers fed rats a similar diet supplemented with the same dosage (4 ml per 100 grams of body weight) of coconut water.
After 45 days, the coconut water group had a reduction in cholesterol and triglyceride levels that rivaled the effects of a statin drug used to lower cholesterol (16).
Keep in mind that this was a very high dose. In human terms, it would be equivalent to a 150-pound (68-kg) person consuming 91 ounces (2.7 liters) of coconut water per day.
Nevertheless, the finding that it reduced cholesterol as effectively as a statin drug is very impressive and should be further investigated.
Animal studies suggest that coconut water may have powerful cholesterol-lowering properties.
