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!

Leave a review for a chance to win signed copies of my cookbooks!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 just had this smoothie today with a raspberry lemon kombucha. I used local peaches I had frozen from this summer (yum!). I did not have cocnut sugar unfortunately so I used local raw honey as a replacement hope that was OK. Also I added chia, ground flax and hemp hearts. This thing was fabulous!!! Thank you!
Hey Shawn – Yep, honey was a great choice to substitute for coconut sugar! I bet that flavor of kombucha worked perfectly! Glad you enjoyed this one. 🙂
What a yummy smoothie… the coconut sugar rim was fun!
I used a ginger kombucha for this and it was amazing! Thanks for the unique recipe!
You had me at kombucha! Soooo good!
Here’s to happy tummies with this smoothie!
Tried it again today! Just used the lime to line the glass and it was delicious!
I was recently informed I should avoid or have only 1 cup per day or phosphorus & potassium rich greens like kale & spinach(major kidney issues cause by two auto immune diseases)
What are some other good leafy greens not loaded with phosphorous and potassium I can use as substitutes?
