7 Health Benefits of Coconut Water and Best Ways to Enjoy It

Whether enjoyed straight from the coconut or conveniently packaged in cartons or bottles, coconut water boasts an extraordinary nutrient profile and a wide array of health benefits, such as providing electrolytes to help keep you hydrated and lower your blood pressure. “Hydration is very important for proper digestive function, especially in the absorption of nutrients and for preventing constipation,” says Hannah Van Ark, M.S., RD, founder of the Plant Forward Nutritionist.

This is why coconut water has become an increasingly popular choice among individuals seeking a natural way to stay hydrated and nourished. Here are some benefits you may gain when you make this tropical beverage a regular part of your routine. 

Why We Love Coconut Water

May Replenish Electrolytes

Coconut water, often dubbed “nature’s sports drink,” is packed with an impressive lineup of electrolytes, including potassium, sodium, magnesium and calcium. These minerals are essential for muscle contraction, nerve transmission and maintaining fluid balance throughout the body. Coconut water’s electrolyte-rich profile makes it an excellent choice for rehydration, particularly following fluid and electrolyte loss from illness (like vomiting or diarrhea) or exercise-induced sweating, says Van Ark. Remarkably, its osmotic composition resembles that of human plasma, making it an ideal beverage for replenishing electrolytes lost during dehydration.

May Lower Blood Pressure

Quenching your thirst with coconut water may positively impact your blood pressure, thanks to its high potassium content. Potassium plays a pivotal role in maintaining optimal blood pressure levels by relaxing blood vessel walls and counteracting the effects of sodium in the body. When sodium levels are too high, the body retains more water, which increases blood volume and raises blood pressure. Potassium steps in by encouraging the kidneys to excrete excess sodium, alleviating pressure on blood vessel walls. One cup of coconut water contains 404 milligrams (9% of the Daily Value) of this heart-healthy mineral, which Van Ark explains is similar to the amount in a medium banana.

May Support Bone Health

While calcium and vitamin D are widely recognized for supporting bone health, some research shines a spotlight on potassium-rich foods and beverages—like coconut water—as vital allies in fortifying bone strength and density. This mighty mineral may be particularly beneficial in preventing osteoporosis, a condition characterized by weakened bones. Along with maintaining electrolyte balance and heart health, potassium also helps regulate acid-base balance in the body. When the body becomes too acidic, it leaches calcium from bones to help neutralize the excess acid, weakening bones over time. However, potassium can intervene by restoring acid-base balance and preventing calcium release from bone. Therefore, a diet rich in potassium is linked to higher bone mineral density, especially in older adults.

May Improve Digestive Health

Sipping coconut water may also enhance your gut health. This benefit primarily stems from coconut water’s hydrating properties. Research has also shown that coconut water has anti-inflammatory and antimicrobial properties that can benefit the gut microbiome, which are the microbes that inhabit your intestines. Coconut water has also demonstrated the ability to help alleviate inflammation and possibly support remission in digestive disorders such as ulcerative colitis. As a result, coconut water may soothe irritated gut linings and offer relief from pangs of digestive distress.

Might Reduce Cell Damage

Each day, your cells face off against harmful molecules called free radicals. These molecules emerge from normal metabolic processes within your body and from exposure to external toxins and pollutants. When the body is flooded with too many free radicals, it can lead to cell-damaging oxidative stress and a heightened risk of developing chronic diseases.

“Antioxidants like vitamin C, cytokinins and phenolic compounds are present in coconut water, and these can fight free radical damage in the body,” says Van Ark. However, she notes that the antioxidant effects of coconut water have primarily been researched in animals. Therefore, more human studies are needed to validate these findings and determine their effectiveness in people.

Might Aid in Blood Sugar Management

Drinking coconut water regularly may also support blood sugar regulation. Several animal studies have shown that coconut water may aid in managing diabetes by lowering blood sugar levels, improving insulin sensitivity and reducing oxidative stress. These beneficial effects are thought to be attributed to coconut water’s high antioxidant content, magnesium levels and the presence of an amino acid called L-arginine. However, it’s important to mention that while animal studies provide valuable insights, further human studies are needed to confirm these effects.

Additionally, some coconut water brands contain added sugar, which could result in blood sugar spikes. Still, coconut water is lower in sugar than many sugar-sweetened beverages like soda, says Van Ark. Therefore, she suggests that swapping these drinks for coconut water may reduce blood sugar levels for some individuals.

Might Prevent Kidney Stones

If you’ve ever passed a kidney stone, you know how excruciatingly painful it can be. These stones are formed from crystallized minerals and salts that accumulate in the kidneys. The most common types of kidney stones include calcium oxalate, uric acid, struvite and cystine stones. Although research is still in its early stages, Van Ark highlights that a small human study of eight participants revealed that coconut water may help prevent kidney stones by increasing the urinary output of citrate. This is good news because citrate is known for halting calcium stone formation. However, we need larger human studies to confirm these findings.

Nutrition Information

The nutrition profile of coconut water varies depending on the age and variety of the coconut, along with how it is processed and stored. In general, this hydrating beverage is a great source of several key electrolytes, including potassium, sodium and magnesium. It also contains a trace amount of calcium. One cup (245 grams) of unsweetened coconut water contains:

• Calories: 44
• Carbohydrates: 10 g
• Dietary fiber: 0 g
• Total sugar: 10 g*
• Added sugar: 0 g

Is Coconut Water Safe for Everyone?

Coconut water is not only a refreshing way to boost your health, but it’s also well-tolerated by most people, making it a safe choice for regular consumption. However, there are a few precautions to be aware of.

Considerations for Kidney Disease

Individuals with chronic kidney disease should seek guidance from a healthcare professional before adding coconut water to their diet. Coconut water is naturally high in potassium, which can pose challenges for those with compromised kidney function. While potassium is usually flushed out through urine, those with kidney issues may have difficulty eliminating excess potassium. Therefore, close monitoring of potassium intake is crucial to prevent complications.

Precautions Regarding Surgery

Similarly, if you have an upcoming surgery, avoiding coconut water for at least two weeks before and after the procedure is advisable. This is because coconut water can potentially affect blood pressure and blood sugar control, so caution is encouraged during this critical period.

Potential Medication Interaction

Consuming coconut water alongside antihypertensive or antidiabetic medications may cause blood pressure and blood sugar levels to drop too low. Therefore, people taking these medications should speak with a healthcare professional before drinking coconut water regularly.

5 Ways to Enjoy Coconut Water

When buying coconut water at the grocery store, check the Nutrition Facts label to ensure it closely mirrors the refreshing beverage you’d find on a tropical beach. Look for options that are free of added sugars and preservatives. Ideally, the ingredients list should contain only one item: pure coconut water. If you come across a brand with a unique pink hue, don’t fret! This is a good sign. When fresh coconut water is exposed to air, it undergoes reactions that turn the liquid pink. And, it’s a sign that it has retained many of its natural antioxidants.

Once you’ve picked the ideal coconut water, consider enjoying your refreshing beverage in the following ways:

• Plain: A tall glass of coconut water over ice is the perfect way to cool down on a hot summer’s day. With its crisp taste and hydrating properties, coconut water is an electrolyte-rich beverage and a refreshing escape to paradise all in one.
• Smoothie: If you’re looking to add some fruit to the mix, consider blending coconut water into a delicious fruit smoothie. You’ll not only be adding electrolytes, but also a subtle tropical flavor to boost your smoothie game.
• Homemade Juice: Whether it’s a homemade juice or a store-bought one, infuse it with the natural sweetness of coconut water.
• Frozen Ice Pop: A childhood classic with a healthy spin, ice pops made with coconut water and fruit are a delightful treat that combines nostalgia with nourishment.
• Cocktails and Mocktails: On those days when you crave a cocktail (or mocktail), try adding coconut water to your favorite drink. If you need some inspiration, give our highly rated Coconut Margarita a try.
