Health benefits of a watermelon smoothie


Watermelon has a high water content, so it’s the perfect fruit for hydration. All that water doesn’t mean it’s lacking in powerful antioxidants. Watermelon actually has about 40% more lycopene than raw tomatoes. Lycopene can help curb your risk of cancer and heart disease, and offers some protective effects against damaging UV rays.


Strawberries add filling fiber to this watermelon smoothie as well as vitamin C, and other beneficial antioxidants. Blood sugar regulation, reducing heart disease risk and boosting immunity are just some of the health benefits of adding strawberries to your diet.


Cherries are also high in fiber and loaded with antioxidants. These powerful antioxidants may protect against cancer, cardiovascular disease, diabetes and Alzheimer’s. Anti-inflammatory compounds in cherries may help reduce muscle pain and damage.

Healthy benefits of a watermelon smoothie include better digestion and skin.

Can I freeze watermelon for a smoothie?

Yes, you can freeze watermelon! Cut the watermelon into cubes or scoop out the flesh with a melon baller. Place the cubes in a resealable freezer bag and lay the bag on its side in the freezer. Check out our smoothie prep ahead article for even more time-saving tips.

5 Watermelon Smoothie Tips

  1. Since watermelon is over 90% water by weight, you don’t need to add any extra liquid or ice to this smoothie.
  2. Use seedless watermelon for this recipe. No need to spend all day picking out watermelon seeds!
  3. Using frozen cherries and frozen strawberries rather than fresh yields a cool and frosty drink. If using fresh, add ice cubes to the blender.
  4. Serve this smoothie  immediately after making. The longer it sits, the watermelon separates from the other ingredients.
  5. Want popsicles? Freeze the smoothie in freezer pop molds to make homemade popsicles for the kids.
