Overview

Coconut water is the clear liquid found inside immature coconuts. As the coconut matures, the water is replaced by coconut meat.

Coconut water is sometimes referred to as green coconut water because the immature coconuts are green in color.

Coconut water is different than coconut milk. Coconut milk is produced from an emulsion of the grated meat of a mature coconut.

Coconut water is commonly used as a beverage and as a solution for treating dehydration related to diarrhea or exercise. It is also tried for high blood pressure.

How does it work?

Coconut water is rich in carbohydrates and electrolytes such as potassium, sodium, and magnesium. Because of this electrolyte composition, there is a lot of interest in using coconut water to treat and prevent dehydration. But some experts suggest that the electrolyte composition in coconut water is not adequate to be used as a rehydration solution.

Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

  • Diarrhea-related dehydration. Some research shows that consuming coconut water can help prevent dehydration in children with mild diarrhea. But there is no reliable evidence that it is any more effective than other beverages for this use.
  • Exercise-related dehydration. Some athletes use coconut water to replace fluids after exercise. Coconut water seems to help rehydrate after exercise, but it does not appear to be more effective than sports drinks or plain water.
  • High blood pressure. Some research suggests that drinking coconut water might lower blood pressure in people with high blood pressure.
  • Other conditions.
More evidence is needed to rate the effectiveness of coconut water for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Side Effects

Coconut water is LIKELY SAFE for most adults when consumed as a drink. There are no known serious side effects.

Coconut water is POSSIBLY SAFE for children.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of coconut water during pregnancy and breast-feeding. Stay on the safe side and avoid use.

High blood pressure: Coconut water might lower blood pressure. It can increase the effects of medications used to lower blood pressure. Discuss your use of coconut water with your healthcare provider if you have blood pressure problems.

Surgery: Coconut water might interfere with blood pressure control during and after surgery. Stop using coconut water at least two weeks before a scheduled surgery.

Some medications for high blood pressure include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

Dosing

The following doses have been studied in scientific research:

BY MOUTH:

  • For high blood pressure: 300 mL twice daily.
  • For exercise-induced dehydration: variable depending on estimated loss of fluid.
