What Is Coconut Water?

Not to be confused with coconut milk (a blend of coconut water and grated coconut), coconut water is the clear fluid found inside young coconuts. Unlike many fruit juices, unflavored young coconut water is naturally rich in electrolytes and low in added sugar and calories. Here’s a quick look at what this hydrating liquid contains.

Coconut Water Nutrition Facts & Electrolytes

A one-cup serving (240 ml) of organic unsweetened coconut water typically provides:

Calories: 60
Protein: 0 grams
Fat: 0 grams
Carbohydrates: 15 grams (5% Daily Value)
Fiber: 0 grams
Sugar: 8 grams

Coconut water also contains key electrolytes that support hydration, help with muscle cramps, and support normal muscle and cognitive function, including:

Calcium: 40.8 milligrams (4% DV)
Potassium: 509 milligrams (15% DV)
Magnesium: 16.8 milligrams (2% DV)
Phosphorus: 19.2 milligrams (2% DV)

If you have a preferred brand, check the supplement facts label for the most accurate nutrition breakdown.

Did You Know? Many people mistake hunger for thirst. Research shows that mild dehydration can trigger cravings, especially for salty foods.

How Coconut Water Supports Hydration

As mentioned above, coconut water contains a mix of electrolytes, most notably potassium, as well as smaller amounts of sodium, magnesium, and calcium. These electrolytes influence where water is in the body and how well it’s retained after you lose fluid, whether that’s through exercise, illness, or lack of water consumption.

In sports nutrition, this interplay between electrolytes and fluid balance is essential for maintaining a healthy hydration status, especially during activities where sweat loss can accumulate quickly.

Sodium is the main electrolyte responsible for retaining water in the bloodstream and surrounding tissues. It also drives thirst and helps the kidneys regulate fluid balance. When it comes to replacing sweat loss, sodium is the single most important electrolyte.
Potassium works inside the cells. When cells take up potassium, they pull water in with it, which supports intracellular hydration. Because coconut water is naturally high in potassium, it tends to draw more water into cells than plain, low-potassium beverages.
Magnesium and calcium are present in smaller amounts. While hydration isn’t their primary role, they support normal muscle and nerve function and help maintain overall fluid balance.

How Do Electrolytes Move Water Between Compartments?

Water moves across cell membranes based on osmotic gradients. In other words, water shifts toward areas with higher electrolyte concentration. When the fluid outside your cells becomes relatively salty, water moves out of the cells. When that outside fluid is more diluted, or when cells take up positively charged ions like potassium, water moves into the cells. This basic process explains why different electrolytes influence cellular hydration in different ways.

How Does Coconut Water Compare to Plain Water and Sports Drinks?

For mild-to-moderate fluid losses, such as recreational exercise or everyday heat exposure, coconut water generally hydrates just as well as plain water or sports drinks. Many people also prefer it for its natural flavor and because it’s easier on the stomach. People who exercise on an empty stomach may also appreciate that coconut water provides fluid and electrolytes without the heaviness or added sugar of a conventional sports drink.

However, coconut water also contains less sodium than the typical sports drink or oral rehydration solution. After heavy sweating from long endurance exercise or intense heat, this lower sodium content means coconut water alone may not restore fluids as effectively. Sodium is essential for replenishing extracellular volume and helping the body retain the water you drink. This is especially true after heavy sweating or exercise, so coconut water is not ideal in high-intensity or endurance situations unless paired with additional sodium.

Did You Know? Coconut water has been used as an IV hydration fluid in remote areas. One case report from the Solomon Islands documented its use in a hospital setting when medical supplies were limited.

Top 5 Benefits of Coconut Water

Aside from supporting hydration, coconut water offers several potential health benefits.

1. Kidney and Urinary Health

Staying well-hydrated is one of the most effective ways to help prevent kidney stones. Stones form when calcium, oxalate, and other nutrients combine to create crystals in the urine. According to the National Institute of Diabetes and Digestive and Kidney Diseases, about 11% of men and 6% of women will experience kidney stones at least once in their lifetime.

Several small studies suggest coconut water may offer additional support for kidney and urinary health compared to plain water. For example, a 2018 study of eight participants found that coconut water increased the excretion of potassium, chloride, and citrate. These are three compounds that help prevent stone formation by reducing crystal buildup in the urinary tract. These findings suggest coconut water could help “flush” the system and lower the likelihood of stones, though larger studies are needed to confirm this effect.

2. Antioxidant Effects

Coconut water is packed with antioxidants—nutrients that protect your body from damage caused by free radicals. Free radicals are harmful molecules produced during normal metabolic processes, and their levels rise in response to stress, inflammation, or injury. When free radical production exceeds your body’s ability to manage them, oxidative stress and cell damage occurs.

Animal research indicates that coconut water contains antioxidants that may help reduce oxidative stress. In a 2012 study, insulin-resistant rats fed a high-fructose diet showed reduced free radical activity when given coconut water. Similarly, a 2014 study found that rats with liver damage experienced significant reductions in oxidative stress when consuming coconut water compared with rats that did not. While these results are promising, human studies are still needed to understand coconut water’s antioxidant effects more fully.

3. Digestive Aid

Coconut water’s antioxidant content may help with inflammation, particularly in regards to gut health. Inflammation can disrupt the balance of bacteria in the gut and contribute to digestive symptoms, so targeting that inflammation may indirectly support digestion.

Early research supports this connection: One study found that coconut water helped with inflammation in the colon. Other studies suggest that coconut water may support healthy metabolism, which can also influence digestive function. However, much of the current research is preliminary, and more human studies are needed to understand how coconut water directly affects digestion.

4. Weight Management

Coconut water is naturally low in calories and contains less fat and sugar than many flavored beverages, such as carbohydrate electrolyte sports drinks, fruit juices, sodas, and smoothies. This makes it a more conscious choice if you want a flavorful drink that won’t significantly increase your calorie intake. While the exact nutrition profile varies by brand, one cup of coconut water typically contains around 60 calories and 8 grams of sugar, and many products contain no added sugar at all.

Because coconut water also supports hydration, it may help reduce feelings of “false hunger” that occur when mild dehydration mimics hunger cues. This can help prevent unnecessary snacking or excess calorie intake.

That said, coconut water should be viewed as a supportive component of a balanced diet, not a weight management strategy. It does not provide meaningful amounts of protein or fat, both of which are important for satiety and overall nutrition.

5. Skin Health

Coconut water is often touted for its hydrating and soothing effects on the skin. While most of the research is preliminary, its nutrient content and natural compounds may offer a few potential benefits when used topically or as part of an overall skincare routine.

Dry or sensitive skin: Coconut water contains natural sugars, antioxidants, and amino acids that can help nourish and moisturize the skin when applied topically. These compounds support the skin’s barrier and may help with dryness or irritation, especially for sensitive skin types.
Acne and scarring: A small 2017 study suggests that coconut water may help reduce the growth of certain bacteria associated with breakouts. While coconut water alone won’t treat acne, it can be used alongside other skincare ingredients to support the skin’s natural healing process.

How to Use Coconut Water for Hydration

There are many ways to enjoy coconut water safely, healthfully, and in a way that supports hydration. Here are a few key guidelines to help you get the most out of your experience.

Serving Size

There are no formal recommendations for how much coconut water to drink. Many people who drink coconut water daily enjoy 1-2 cups per day, while others use it as a sports drink substitute after a moderate workout.

When Coconut Water Works Best (And When it Doesn’t)

Because coconut water is naturally high in potassium and relatively low in sodium, it works well for everyday hydration but isn’t always the best choice for situations involving significant fluid and electrolyte losses. It’s well-suited for:

Before and after mild to moderate workouts
During everyday heat exposure
Long, hot walks or outdoor activities
Light dehydration from travel or busy days

In more demanding scenarios, such as intense physical performance or long endurance training, heavy sweating in hot/humid conditions, or if you follow a low-sodium diet, a higher-sodium electrolyte drink may be more appropriate. You can also pair coconut water with saltier foods to help balance electrolytes.

Tips From a Dietitian

Coconut water can be enjoyed in various ways depending on your preferences and hydration needs. Here are a few tips to keep in mind:

For a lighter, more refreshing taste, serve it cold or over ice.
Mix it with water to reduce sweetness and calories.
After a workout, sip it slowly instead of chugging to support absorption and reduce stomach discomfort.
Add it to smoothies for natural sweetness, extra electrolytes, and a more satiating healthy snack.
For a more complete electrolyte profile, try an electrolyte powder that features coconut water and added electrolytes, like Live It Up Vital Minerals.
