According to Healthline, coconut water is a low-calorie drink, almost without fat but provides many important electrolytes such as potassium and magnesium.
A cup of coconut water of about 240ml only contains about 45 calories but still provides a significant amount of minerals to help maintain water balance in the body.
Not only supporting hydration, many studies also recorded that coconut water can bring remarkable benefits to blood sugar, cardiovascular health, kidney function and post-exercise recovery. Specifically:
1. Rich in antioxidants
During metabolism, the body continuously produces free radicals. When the amount of free radicals increases excessively, the body can fall into oxidative stress - a factor related to many chronic diseases.
A study published in 2025 showed that coconut water has the ability to neutralize free radicals thanks to containing many natural antioxidant compounds. Even in some laboratory trials, the antioxidant activity of young coconut water was recorded to be equivalent to or higher than vitamin C.
2. Can support blood sugar control
Coconut water can provide magnesium - a mineral that plays an important role in the body's insulin use. According to the American Diabetes Association, supplementing enough magnesium can help improve insulin sensitivity in people with pre-diabetes and type 2 diabetes.
However, coconut water still contains natural carbohydrates, so patients need to use it in appropriate amounts.
3. Can support kidney stones prevention
Drinking enough water is one of the important measures to help reduce the risk of kidney stones.
Some small studies show that coconut water can help increase the excretion of citrate, potassium and some minerals through urine. This can contribute to limiting the formation of mineral crystals - factors that lead to kidney stones.
4. Brings benefits to the cardiovascular system
Experts at Healthline believe that antioxidant compounds and polyphenols in coconut water can help reduce oxidative stress, support blood vessel activity and contribute to maintaining healthy blood pressure.
Some studies also recorded that coconut water has the potential to support fat metabolism and improve the body's energy use efficiency.
5. Support for water replenishment after exercise
Thanks to containing electrolytes such as potassium, magnesium, sodium and calcium, coconut water is considered a natural water replenishment option after exercise.
A study published in 2025 showed that coconut water is as effective in restoring water after exercise as some commercially available sports drinks containing electrolytes.
However, experts recommend choosing pure coconut water, without sugar or flavoring, to maximize health benefits.
