What are the Benefits of Drinking Watermelon Juice?

Watermelon is almost 92% water, so it’s ultra-hydrating while also being low in calories. Watermelon has only 46 calories per cup!

Here’s what else I love about watermelon:

  • The lycopene found in watermelon (which gives it a bright red color) may help to lower cholesterol.
  • Watermelon is also a good source of citrulline, which is an essential amino acid. It may help blood vessels expand, which could help to lower blood pressure.
  • Since watermelon is rich in antioxidants, it may help to lower inflammation. One study suggests that the lycopene and vitamin C in watermelon might help to lower markers of inflammation.
  • Drinking watermelon juice may help with muscle recovery and soreness after a workout.

And let’s not leave out the fact that watermelon is delicious and refreshing! I can’t believe it’s taken me so many years to try making watermelon juice, because it’s what I want to serve at every summer party from now on.

How Long Does Juiced Watermelon Last?

Watermelon juice will keep well in the fridge for up to 3 days, as long as you store it in an airtight container. The flavor can start to taste less fresh after that amount of time, so I don’t recommend making it too far in advance if you plan on serving this to guests.

What Fruit Goes Well with Watermelon?

Sweet watermelon pairs perfectly with a squeeze of fresh lime juice. I also love adding in a few fresh mint leaves to the watermelon juice when I have them on hand. Adding fresh herbs almost always elevates the flavor of any recipe!

If you want to add more fruit to this recipe, try blending in a few ripe strawberries, or you can swap the mint for a few fresh basil leaves instead. Either way, you can’t go wrong!

How to Make it in a Blender

Because watermelon is so hydrating, you don’t even need a juicer to make it. Just toss the ingredients in a blender and blend until smooth! If you have a high-speed blender, like a Vitamix, you don’t even need to worry about the seeds. They will get totally pulverized.

If using a standard blender, I would recommend starting with a “seedless” watermelon so you don’t have to worry about picking out any black seeds.

For an extra-smooth juice, you can pour the blended watermelon though a fine mesh strainer, but I usually don’t find that’s necessary. The watermelon pulp isn’t any more noticeable than the pulp you’d find in freshly squeezed orange juice.

Can You Juice Watermelon in a Juicer?

Yes, of course! When I run watermelon through a juicer, sometimes I’ll throw in the whole green rind, too.

Watermelon rind is a source of the amino acid citrulline, which may help boost athletic performance. (The rind can make the juice a little less-sweet, though, so keep that in mind if you are making this for company.)

Course Drinks
Cuisine vegan
Keyword watermelon juice
Prep Time 10 minutes
Cook Time 0 minutes
Total Time 10 minutes
Servings 2
Calories 96kcal



  • 4 cups watermelon , cut into cubes (580 grams)
  • 2 tablespoons fresh lime juice (25 grams)
  • 3-4 small fresh mint leaves (optional)


  • In a blender, combine the watermelon, lime juice, and mint leaves, if using. Blend until completely smooth. (The key to this juice having a good flavor is the watermelon; make sure it's ripe and sweet before you begin!)
  • You can serve this juice right away; there's no need to strain it! But, you can pour it through a fine-mesh strainer if you prefer a totally smooth drink, with no watermelon pulp.
  • I like to serve this watermelon juice over ice, and garnish the glass with sliced watermelon and lime. Leftover juice can be stored in an airtight container in the fridge for up to 3 days.


Feel free to modify this recipe as you see fit! I imagine it will work well with lemon juice instead of lime, and with fresh basil instead of mint. Or leave the herbs out all together! It's really hard to go wrong as long as your watermelon tastes sweet.

I love watermelon juice!


It’s a very good practice, I love juice.


Yum! I used this recipe as a math lesson for my 8 year old. She had to make 3 servings – when she went to pour it over ice, she discovered she had enough for 6 servings. She did fill her glasses with ice so if you serve it without, it probably would have come out to 3 servings.


I tried it with hint of ginger and some lime juice and it was perfect 👌


Ohh! Watermelon is one of my favorite items. Nice to hear that you are a Vegetable enthusiast. Really I’m also a vegetarian
