Rainbow Antioxidant Smoothie

I love using fresh juice as a base for smoothies. We get to combine electrolyte and antioxidant rich green juice with equally nutrient-packed frozen fruits and a dash of superfoods for an energizing start to the day!


The before photo colors are a vibrant, bright and beautiful rainbow of phytonutrient rich fruits and veggies. The after photo below… well all those colors combine into a mixed palate producing more of a darker, brownish hue. So while it may not be as pretty it sure is tasty and super healthy. And as you can see from my assistant, Dillon, it’s kid approved!

Since Dillon has food allergies and I’m also gluten-free, our smoothies are dairy-free, soy-free and GF as well.  It’s easy to be allergy-friendly when you use fresh ingredients.  We follow the dirty dozen for organics.

Loaded with immune supporting nutrients, this smoothie isn’t just for breakfast. It’s also a perfect pre- or post-workout drink. Add some plant-based protein powder to make it an even more effective post-workout refresher that can replenish your muscles with the energy they crave.

To read more about Maca as a superfood, here’s my recent post published on Reboot with Joe.
