Nutrients in Watermelon Pineapple Juice

Let’s take a closer look at some of the key nutrients found in watermelon pineapple juice and their health benefits:

Vitamin C

Pineapple is one of the richest sources of vitamin C, providing 131% of the recommended daily value in just one cup. When combined with watermelon, which also contains vitamin C, this juice is a powerhouse for this essential nutrient.

Vitamin C acts as an antioxidant to prevent cell damage. It also plays a role in immune function, wound healing, iron absorption, and the production of collagen for healthy skin and connective tissues.


The red pigment that gives watermelon its color is called lycopene. This powerful antioxidant has been linked to many health benefits, including improved heart health, lower cancer risk, and protection against oxidative damage and inflammation.

Watermelon is the highest dietary source of lycopene. Adding it to pineapple juice significantly boosts the lycopene content compared to pineapple alone.


Both watermelon and pineapple contain potassium, an important mineral that regulates fluid balance, nerve signals, and blood pressure. With a combination of these fruits, you can get a significant dose of potassium in one serving.


Pineapple contains an enzyme known as bromelain, which has anti-inflammatory, digestive, and other therapeutic effects in the body. Bromelain may help reduce swelling, bruising, healing time after surgery, and nasal congestion.

Making Watermelon Pineapple Juice

Watermelon pineapple juice is easy to make at home with just a few simple steps:

  1. Wash and chop 1 small seedless watermelon into chunks.
  2. Peel and core 1 fresh pineapple, cutting it into chunks.
  3. Add the watermelon and pineapple pieces to a blender.
  4. Blend on high until smooth, at least 1-2 minutes.
  5. Pour through a strainer or cheesecloth to remove any foam or pulp (optional).
  6. Enjoy immediately, or store in an airtight container in the fridge for up to 3 days.

For added sweetness, you can add a tablespoon or two of honey or agave nectar. Garnish with mint leaves or lime wedges.

You can also add a splash of water or coconut water when blending to achieve your desired consistency.

Possible Drawbacks of Watermelon Pineapple Juice

  • Acidic – The acidity from the pineapple may irritate sensitive teeth or digestive systems when consumed in excess.
  • Oxalates – Watermelon contains some oxalates, compounds that can contribute to kidney stone formation in those prone to them.

As with any fruit juice, it is healthiest to consume watermelon pineapple juice in reasonable portions as part of a balanced diet.
