Coconut Water Benefits & The Best Ways To Drink It, From Nutritionists

Known for its nutty and refreshing flavor, coconut water is a popular drink around the world. Beyond being delicious, coconut water also has some serious nutritional perks—especially for those searching for an electrolyte fix after breaking a sweat. Here's what to know about the top health benefits of coconut water, and how it compares to the other bevs in your fridge.

Besides serving as a refreshing alternative to plain water, coconut water is also rich in electrolytes like potassium1. For this reason, it's often used to help rehydrate, especially after exercising or any time you're feeling under the weather.

Coconut water packs a hearty dose of several nutrients into each serving, including potassium and vitamin C. Compared to many popular varieties of sports drinks2, it's also slightly lower in calories and carbs. Here is a closer look at how 1 cup of unsweetened coconut water3 stacks up in terms of nutrition:

Compared to regular water, coconut water is also higher in electrolytes like magnesium and calcium, which can help maintain fluid balance6, according to Desiree Nielsen, R.D., a dietitian and author of Good for Your Gut. This makes coconut water a popular alternative to sugary sports drinks for refueling after an intense sweat session.

Beyond its refreshing flavor and electrolyte profile, coconut water is a great source of antioxidants and can help you stay hydrated. Plus, it's also been associated with a few impressive health perks, especially for heart health and blood sugar levels:

Early research found that young coconut water could significantly reduce inflammation9, which could be partly due to its antioxidant content. Another preclinical study showed that coconut water derived from green dwarf coconuts possessed powerful antioxidant properties7 and was effective at protecting against oxidative damage. However, more research in humans is needed. It is also important to note that pasteurization may reduce the antioxidant capacity in coconut water10.

According to Nielsen, coconut water supplies several important nutrients involved in regulating blood pressure levels, including potassium. Interestingly, one study found that getting enough potassium in your diet could be linked to lower blood pressure levels11. What's more, another preclinical animal study showed that coconut water could suppress a hormone system that regulates blood pressure12, acting as a natural diuretic to increase urine output, which could potentially help decrease blood pressure.

If better blood sugar control is your goal, be sure to choose an unsweetened brand of coconut water and enjoy it alongside a balanced diet.

Coconut water could be beneficial against kidney stones, which are small, hard deposits that form in the kidneys, causing symptoms like pain, nausea, and vomiting. One small study found that coconut water could increase the excretion of potassium15, chloride, and citrate in the urine, which could reduce the risk of developing kidney stones. Coconut water can also help you stay hydrated16, which has been tied to a reduced risk of kidney stones. However, more high-quality research is still needed.

However, whether or not coconut water holds any hydrating benefits over regular water has been called into question. According to one study, coconut water was not more effective at improving markers of hydration17 during exercise compared to plain water. Another study concluded that coconut water did not offer any additional benefits for rehydration18 over other drinks, including conventional sports drinks with sodium.

People with kidney disease might also need to limit their intake. In fact, Nielsen tells mindbodygreen that trading regular water for coconut water could ramp up potassium intake, which could be harmful if your kidneys aren't functioning at 100%.

Additionally, keep in mind that coconut water has a shorter shelf life than regular water and requires proper storage to prevent it from going bad. Once it's opened, it's best to enjoy the same day or seal and store in the refrigerator for up to five to seven days.

Besides being nutritious and flavorful, coconut water is also super versatile. Here are a few creative ways to start sipping:

Coconut water can supply several important nutrients, including electrolytes like potassium, magnesium, and calcium. It may have an edge over regular water in some instances, especially in terms of its antioxidant content and effects on blood sugar or blood pressure levels. However, there are also a few side effects of coconut water to consider, and drinking too much could even cause digestive distress. Therefore, your best bet is to enjoy coconut water in moderation, alongside regular water and a variety of other healthy drinks in your daily diet.
