One of the best things we can do as we age is consistently eat foods rich in antioxidants. I know “forever young” isn’t realistic—but supporting our bodies as we move through life absolutely is. Antioxidant-rich foods like berries and cherries are packed with color, flavor and vitamin C.

That’s why I love these Antioxidant Smoothie Cubes so much. If tossing a few frozen cubes into my daily smoothie can help protect my skin, support long-term health, and keep me feeling vibrant, you better believe I’m stocking my freezer. It’s a small habit, but one that adds up in the best way.

How to Use Antioxidant Smoothie Cubes

These cubes are designed to make smoothies easier, not more complicated. Add 4 cubes to any of my smoothie recipes in place of ½ to 1 cup of fruit. They pair especially well with leafy greens, banana, citrus, and non-dairy milk or water.

Because they’re frozen, they also help create a thick, frosty texture—no extra ice needed.

Ingredient Swaps

This smoothie cube recipe is flexible and forgiving. Use what you have and adjust to taste:

  • Swap cherries for blueberries or blackberries.
  • Replace strawberries with raspberries if preferred.
  • Use beet powder in place of fresh beet if needed.
  • Substitute pomegranate juice with unsweetened cranberry juice or cherry juice.

The goal is progress over perfection—any combination of colorful plants still delivers antioxidant benefits.

While these are a great starting point to boosting your health, I’ve gone even deeper to bring you some supercharged smoothie cubes that are loaded with antioxidant foods.

Common Questions

Which foods have the most antioxidants?

Foods highest in antioxidants are typically colorful, plant-based foods like berries, cherries, pomegranate, beets, leafy greens, citrus fruits, and brightly colored vegetables. These foods contain compounds such as anthocyanins, polyphenols, flavonoids, and vitamin C. Blending a variety of these foods into smoothies is an easy way to consistently increase antioxidant intake.

What drinks are high in antioxidants?

Drinks high in antioxidants are usually made from deeply colored plants, teas, or minimally processed fruits. Some of the best options include berry smoothies (especially with blueberries, cherries, cranberries, or elderberries), pomegranate juice, and tart cherry juice, all rich in polyphenols and anthocyanins. Green tea and matcha are standout choices thanks to their catechins, while herbal teas like hibiscus and rooibos also deliver antioxidants without caffeine. Cacao drinks made with unsweetened cacao powder and vegetable-forward smoothies with greens, beets, and citrus round out the list. Rotating these drinks helps you get a wider range of antioxidant compounds with very little effort.

What are the benefits of antioxidant smoothie cubes?

Antioxidant smoothie cubes make it easier to consistently enjoy antioxidant-rich foods. Because they’re prepped and frozen, you can boost the nutrient density of any smoothie without extra effort, helping protect cells and support healthy aging with a simple daily habit.

Recipe Notes

  • Fruit Tip: Fresh or frozen fruit both work; pit fresh cherries first. Let frozen fruit thaw slightly before blending so it’s easier on your blender.
  • Beet Tip: There’s no need to cook the beet; raw works well. Chop it small so it blends smooth.
  • Juice Swap: Use 1/2 cup 100% unsweetened cranberry juice in place of the pomegranate juice, adding a splash of water if the blender struggles.
  • Freezing: Store the cubes in an airtight, freezer-safe container for up to 3 months. Add them to the blender straight from frozen.
