Why you’ll love it

• Naturally hydrating: Coconut water delivers potassium and magnesium, making this a natural electrolyte drink perfect for post-workout rehydration.
• Packed with antioxidants: Pomegranate juice and blueberries bring rich, fruity flavor and a mega dose of polyphenols.
• Quick and easy: All you need is one glass and five minutes of your time.

The ideal 4th of July mocktail

This drink has red, white, and blue layers—making it the perfect non-alcoholic option for the 4th of July! Just add in a festive straw and you have the best party drink. If you don’t want to make individual drinks, you can also make a larger pitcher by multiplying the recipe by 4 or 8 servings.

Is it healthy?

Absolutely! This colorful mocktail is loaded with nutrients that support hydration, immune function, and recovery:

• Coconut water is a low-calorie beverage that naturally contains electrolytes like potassium, magnesium, and sodium.  Each brand may vary but one cup of coconut water generally contains 470 mg of potassium which is 10% of the daily recommended intake, and 19 mg of magnesium, which is about 5% of the daily value for adults. It’s what makes this a low sugar electrolyte drink without the added syrups found in many store-brought options.
• Pomegranate juice is rich in antioxidants, specifically polyphenols like punicalagins, which may help reduce inflammation and support heart health. Research shows drinking pomegranate juice regularly can help lower blood pressure, which is great news for your heart. The biggest benefits were seen in the first two months, especially when people drank around a cup or less each day.  
• Blueberries are known for their anti-inflammatory and antioxidant benefits 

Together, these ingredients make this delicious DIY electrolyte drink a refreshing and effective homemade sports drink that’s as good for your body as it is for your taste buds.

Ingredients you’ll need

Here’s what you’ll need to whip up this homemade sports drink:

• Coconut water: Choose one with no added sugars. This serves as the hydrating base.
• Pomegranate juice: I always love using POM’s 100% pomegranate juice.
• Fresh lime juice: Adds citrus brightness and a vitamin C boost.
• Blueberries: Both fresh and frozen work. Frozen will chill your drink and slowly infuse it with flavor.

How to make pomegranate blueberry electrolyte cooler

This DIY electrolyte drink is as easy as it gets:

Step 1: Pour your base

Add coconut water, pomegranate juice, and lime juice to a tall glass.

Step 2: Add berries and ice

Drop in your blueberries and ice. Frozen berries are especially great because they act like little fruit ice cubes.

Step 3: Stir and sip

Stir everything together and enjoy right away.

Recipe tips and tricks

• Serving Suggestions: This cooler is perfect as a post-workout drink, summer sipper, or mocktail at your next backyard hangout. You can also pair it with a light snack like a protein bar, fruit, or whole-grain crackers for balance.
• Troubleshooting: Using frozen blueberries? They may clump together—give the drink a good stir or lightly mash to help them disperse evenly.
• Scaling: Making this for a group? Scale up the recipe to fill a pitcher—just multiply the ingredients by 4 or more. Store in the fridge and add ice right before serving.

Customize it your way

Like all of my recipes, this one is completely customizable. You get to make it your own:

• Juice of your choice: Not a pomegranate fan? Try tart cherry juice, cranberry juice, or even a splash of orange juice for a sweeter twist.
• Feel free to add sweetener: Want it sweeter? A touch of honey, agave, or maple syrup works beautifully.

Can I make it ahead of time?

Yes! Simply mix the coconut water, juice, and lime in advance and store in a mason jar in the fridge. Add berries and ice when you’re ready to drink. It’s a great option to pack for work or after a workout—and even better, this DIY electrolyte drink stays fresh and flavorful for hours.

Can I keep leftovers?

If you don’t finish your cooler all the way, you can leave it in the fridge for up to 1 day. Just note that the blueberries may soften the longer it sits.
