Watermelon Smoothie Health Benefits

Provides Hydration

Watermelon is one of the best fruits for staying hydrated.

It has a high water content, so it will contribute to your daily fluid intake.

The fruit also contains magnesium and calcium. Both minerals are electrolytes, which help maintain your body’s hydration.

Supports Digestion

The watermelon and strawberries in this smoothie are high in fiber.

Fiber is essential for healthy and regular digestion. Without enough fiber, there’s a higher risk of gut issues.

Chia seeds also add some fiber to the drink.

Contains Antioxidants

When you drink this smoothie, you’ll get a lot of antioxidants.

Antioxidants are beneficial compounds that fight free radicals. This is important because free radicals can cause cell damage over time.

The watermelon contains antioxidants like lycopene, vitamin C, and vitamin E. Strawberries, like other berries, provide anthocyanins.

Promotes Heart Health

Watermelon is great for your heart. Its fiber content can help reduce high cholesterol, a risk factor for heart disease.

It also contains lycopene, an antioxidant that may help improve heart function.

Ingredient Notes

Ingredients for a watermelon smoothie.
  • White grape juice
    White grape juice adds brightness, sweetness, and a slight tart flavor. To ensure the drink is healthy, choose 100% all-natural white grape juice without added sweeteners.
  • Chia seeds
    As a thickener, chia seeds will make this smoothie satisfying to drink. The ingredient is also rich in anti-inflammatory fats and fiber.
  • Watermelon
    The juiciness of watermelon will help you stay hydrated. Use seedless watermelon for the smoothest blend.
  • Frozen strawberries
    Naturally sweet, strawberries are so tasty with watermelon. Be sure to use frozen strawberries for a cold and thick drink.

Optional Add-Ins

Protein powder

Protein powder will make your smoothie more filling. It will also support muscle growth and maintenance, which is important if you workout.

In this recipe, unflavored protein powder will taste best. You can use whey or plant-based products.

Another option is powdered collagen, a beneficial supplement for joint and skin health.

Leafy greens

For an instant green smoothie, add 1 cup baby spinach or kale to this recipe.

When loading the blender, add the leafy greens after the chia seeds and before the watermelon.

Leafy greens will add antioxidants, vitamins, and fiber to the drink.

Extracts

If you love tropical flavors, add ½ teaspoon coconut extract to this smoothie.

It will taste delicious with the watermelon and strawberries.

Blender Tips

Cut fruits into pieces.

Always chop watermelon before adding it to the blender.

If you have a high-powered blender, the watermelon can be cut into the same size as apple quarters.

Chop the watermelon into smaller pieces if your blender not very powerful.

Add liquids to the blender first.

An easy way to avoid air pockets is to load ingredients from lightest to heaviest.

When the liquids and liquid add-ins are loaded first, it creates a vortex that pulls ingredients toward the blades. This ensures a thorough and even blend.

After the liquids, load any powders or seeds. Follow with leafy greens, fresh fruits, and heavy ingredients like ice and frozen fruit, in that order.

Avoid blending on low for too long.

Blend on low speed for 10 seconds, then quickly increase to high speed for the time listed.

Don’t blend on low for too long, as this can overheat your blender’s motor.

Prevent air pockets with a tamper.

Another way to create a smooth blend is to use a tamper.

Most blenders come with a tamper. This is a tool that’s inserted through the lid of your blender as the blades are moving.

The tool has a stopper, so it won’t reach the blades. Instead, you can move the tamper in a circle to help push ingredients toward the blades.

This will promote smooth blending and an even texture.

Use a blade scraper.

To reduce food waste, use a blade scraper to remove the last bit of smoothie.

A blade scraper is designed to reach underneath the blades of a blender.

Expert Tips

  • If possible, buy frozen sliced strawberries, which are easier for blenders to puree. You can also halve or quarter fresh strawberries before freezing them.
  • Feel free to use fresh strawberries and frozen watermelon. It will create the same flavor profile.
  • For a less sweet smoothie, use coconut water instead of white grape juice.
  • Add a splash of white grape juice if the smoothie is too thick, then blend for 10 seconds.
  • Drink this smoothie as soon as you make it. The leftovers can be refrigerated for 2 days, but the ingredients will likely separate. Be sure to stir before drinking.

Questions You May Have

What fruit mixes well with watermelon?

Watermelon has a mild flavor, so it works well with many fruits. It’s delicious with berries, mango, bananas, and pineapple.

Do I need to add ice?

This watermelon smoothie uses frozen strawberries to chill and thicken the drink. You can add a few ice cubes, but avoid using too much, which can dilute the flavor and texture.

Can I use milk?

For a creamier watermelon smoothie, you can replace the white grape juice with milk. Unsweetened almond milk and coconut milk from a carton are the best choices.
