If you’re looking for an easy way to support gut health without overthinking it, this Probiotic Smoothie is a great place to start. It’s light, refreshing, and naturally fizzy thanks to kombucha, with frozen peaches adding just the right amount of sweetness.
This is one of those smoothies that feels more like a treat than a “health thing”—especially with the lime-sugar rim—but it still delivers real benefits. Simple ingredients, quick prep, and a flavor combo that keeps you coming back.

Why I Love This Probiotic Smoothie
Gut health plays a big role in how we feel day to day—from digestion and energy to mood and immunity. Probiotics help support a healthy balance of bacteria in the gut, and this is one of the best green smoothies to get them in.
Instead of relying on supplements, this recipe uses kombucha as a natural probiotic source and pairs it with fruit, leafy green vegetables, and optional plant-based protein for balance.

Ingredients You’ll Need
This smoothie comes together with just a handful of ingredients:
- Spinach: A gentle leafy green that blends easily and adds fiber and micronutrients.
- Kombucha: Provides probiotics and a light, refreshing tang.
- Frozen peaches: Naturally sweet, and a low-sugar fruit, it’s thick and creamy once blended.
- Collagen peptides: Helps turn this into a more filling snack or light meal. If you’re vegan, swap it for my homemade protein powder or leave out.
- For the rim: Dip the glass rim into lime juice and coat with coconut sugar to add a subtle caramel-like sweetness to the rim. Completely optional, but fun!

Nope. Blending kombucha does not destroy its beneficial probiotics. As long as you’re using raw, unpasteurized kombucha and not heating it, those live cultures stay intact and active in your smoothie.
Only lightly. The frozen peaches naturally sweeten the smoothie and balance kombucha’s tang. If you’re new to kombucha, choose a mild flavor (like ginger or plain) and avoid strongly spiced varieties.
Yes. Collagen peptides don’t interfere with probiotics and blend in easily. They’re flavorless and dissolve smoothly, making them an easy add-in for extra protein and amino acids.
Not at all. The rim is optional and purely for fun. It adds a little sparkle and brightness, but the smoothie is just as nourishing and delicious without it.
I ran out of peaches so used pineapple and frozen mango and used water instead of kumbucha. It was a bit weird with the lime so I added banana and it was sooo good. These are so easy to tweak and make them to your taste.
I think I’ve found a new favorite in this Peach Probiotic Green Smoothie. The flavor popped, which is what I look for in a green smoothie. The ginger kombucha added just that hint of zing, and the peaches were sweet. I never thought to use kombucha before, but I’ll have to keep experimenting in the future. Disclosure: I used fresh peaches and frozen kale cubes (I ran out of spinach, but had plenty of kale), and I used the 1/2 lime to wet the rim of the glass before mixing it into the smoothie. (I dipped the glass in the coconut sugar after liming the rim.)
This is so yummy! I used fresh peaches instead of frozen peaches and it was so sweet and fresh! The hint of lime gets me every time too! SOO GOOD! Loved the addition of kombucha to this smoothie. I have never added kombucha to a smoothie before and I’m for sure going to do it again!! Loved the zing!!! Give this a try for sure!
Loved this smoothie. Just became one of my favorite smoothies. I have never used kombucha in a smoothie before and wasn’t sure about it. Now I am sure. Great! I used pink lady apple flavor. It gave the smoothie a crisp flavor. Just loved it.
So so so so GOOOOOD! I loved that hint of lime. I left off the coconut sugar because I was taking it to go in the car, but I imagine it would be amazing…and will definitely try it the next time I make it. The Kombucha I used was Strawberry Lemonade flavored…. I was scared because it smelled like vinegar and I don’t care for vinegar…but it didn’t taste like it at all. I don’t like Kombucha on its own….but can DEFINITELY drink it in a smoothie – BRILLIANT idea!
