Antioxidant Berry Smoothie Cubes


Here’s the ultimate list of antioxidant foods, along with antioxidant benefits + all natural supplements in the form of fun smoothie cubes!

Give your smoothie a viscous boost of ruby red goodness with these our natural DIY antioxidant berry cubes you can make at home.

Last week, I shared my Vitamin C Smoothie Cubes. A TON of you went wild over them and it made my day! Now, I want to build upon this hack and help you boost your smoothies with homemade smoothie cubes using antioxidant foods that are plant-based. These are going to be our “Forever Young Smoothie Cubes.”

Some of the most vibrant of fruits and vegetables are ruby-hued beets, pomegranates, cranberries, strawberries, and cherries. Their beautiful colors come from being rich in antioxidants, which are vital to us aging more gracefully. (and I need all the help I can get right now!)

Do antioxidants help our body?

Absolutely! Antioxidants help protect against disease and illness by counteracting or protecting cells from damage done by free radicals. Free radicals are the toxic by-products of oxidation and damage healthy, living cells by creating “oxidative stress.”

Did you know that bright, jewel-toned fruits and vegetables are high in the antioxidant, anthocyanin. This antioxidant gives these foods their gorgeous color and may help improve eyesight, reduce inflammation, prevent certain cancers, lower blood pressure, and protect the liver.

The National Cancer Institute estimates that 95% of adults don’t consume enough red and orange vegetables. That’s pretty much ALL OF US! Let’s change that statistic right now! The addition of even just one red fruit or veggie into your day is beneficial.

With that said, these Antioxidant Berry Smoothie Cubes can help you do just that – blend everything up and freeze the concentrate to add to your daily smoothie.

Antioxidant Powerhouse: Beets

Beets are a little different than their anthocyanin counterparts. They contain betalain, the phytonutrient (phyto = plant), that fights disease and inflammation.

Betalain has been shown to be a powerful Phase II detoxifier in the body. It hooks onto toxins and makes it possible for your body to flush them out.

In addition to folate, beets contain iron, potassium, copper, manganese, magnesium, phosphorus, and vitamins B6 and C. The fiber in beets has been shown to be extra beneficial for the digestive system.

Bottom line: you should be eating (or blending!) beets on a regular basis.

Berries, Cherries, and Pomegranate

Berries are one of the best sources of anthocyanin. The vibrant or dark purples, fuchsias, reds, and oranges are jam-packed into these sweet, juicy fruits. Here’s a few that we’re using in the cubes…

Strawberries are very high in vitamin C and may even help lower bad cholesterol and raise good cholesterol levels.

Cranberries are on of nature’s superfoods with the highest concentration of antioxidants. They are low in sugar and calories, high in fiber, and great for helping improve blood sugar levels. Cranberries help protect the urinary tract by helping prevent E.coli from adhering to the walls of the urinary tract. The antioxidants in cranberries provide anti-inflammatory benefits for UTIs and other ailments.

Cherries are one of my favorite summer fruits! The antioxidants in cherries provide many of the same benefits listed above. A special thing about cherries is that they are a natural source of melatonin, the hormone that helps regulate the body’s natural circadian rhythm. Cherries are anti-inflammatory and may improve memory and blood sugar regulation.

Pomegranate originated in modern day Iran and India and are one of the Plant Kingdom’s greatest sources of protective antioxidants. Studies are showing that drinking 100% pomegranate juice may help protect against neurodegenerative diseases like Alzheimer’s and cardiovascular disease like arteriosclerosis (hardening of the arteries). Pomegranate has three (three!!!!) times the amount of antioxidants of red wine and green tea.

As we wrap this up and dive into the actual recipe, I just want to make sure you understand how beneficial these smoothie cubes are for your body. Rather than buy supplements, turn your kitchen into a FARM-acy and have fun doing it! I really hope you enjoy this recipe…

How to use Antioxidant Berry Smoothie Cubes

  1. Add them to any smoothie recipe you’re already making to get a boost of antioxidants and a tart berry flavor.
  2. Create an entire new smoothie using them as your base. I’d recommend pairing with oranges or bananas, they compliment the flavors really well.
  3. Find recipes that includes cherries, berries, beets or pomegranates and swap out for a few smoothie cubes. Here’s a few I would work from:
    Cranberry Kale Cooler
    Spinach Berry Smoothie
    Cherry Pineapple Smoothie Bowl
  4. Add them to a vanilla protein shake to add some fresh plant-based goodness.

    I love the idea of these cubes. Sometimes I buy fresh fruit and something happens and I forget to eat it and it goes bad. This is a great idea to just make a batch at one point and have it frozen. Can you whiz up frozen berries as well? And what about fresh spinach?

  2. Sally says:

    Oh how I lurve lurve lurve this brilliant idea.
    My biggest obstacle is gathering all the ingredients daily. I’m exhausted just thinking about it. Chronic Fatigue is such a drag.
    So far I have made a medium sized jar of the organic powder supplements I like to add. Such as Kakadu plum, kale, beetroot, spirulina, maca, turmeric, matcha and hemp seeds. One rounded
    teaspoon adds it all.
    This one and your Vit C cubes really take it up a notch. BIG THANK YOU.

      So glad they’re able to make your smoothie making easier, Sally!

    This is going to be one of my favorites………….for sure. As for blue….how about white cauliflower, blue berries, cucumber peeled, pineapple, coconut water, flax seeds (ground or whole). It comes out blue, not really a deep blue, but blue !
    P.S. I like the popsicle idea !

    • SGS Rawkstar Carissa says:

      Hey Stepha,

      Ooo that sounds like a great option! Thank you for sharing 🙂

  4. Christy says:

    The photography for this recipe is beautiful! I’m going to try these as healthy frozen popsicles.

    • SGS Rawkstar Carissa says:

      Thank you Christy! We really do have an amazing photographer. Cannot wait for you to try these out.

      Thanks Olivia! Cannot wait for you to give them a try 🙂

  6. Jen Hansard says:

    So glad you’re digging the smoothie cubes Dani! I have a few more coming up since they’ve been such a hit! As for swapping these for the cranberries in the Cranberry Kale Smoothie, that’s the perfect way to do it! you’ll be supercharging that smoothie with waaaay more antioxidants and the flavor will still be delicious. I would say any recipe that has cherries, cranberries, pomegranate, beets and strawberries will work really well to swap these cubes in. Thanks for rawkin’ out with us!

  7. Dani Mitchell says:

    I’m not a big fan of beets, but after reading all those health benefits I think I’m gonna give this one a go. I love all the other ingredients, especially pomegranate juice. I’ve been on a kick with that lately. Do you think these would taste better in a certain smoothie? Like I’m thinking I could take the Cranberry Kale Smoothie and swap out the cranberries for a few smoothie cubes. Would that work?

    • SGS Rawkstar Carissa says:

      Hey Dani,

      Yes that would totally work! This would definitely be great to use in a smoothie that has berries in it. That way it will be a super easy swap!
