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.
Made this with nectarines instead of peaches, as that’s what we had on hand. Delicious! Used ginger kombucha because it’s yummy, and this was a lot of fun.
Yuck! We hated this one. Sour and bitter with hardly any sweetness.
This was really really yummy, even without the coconut sugar rim, just way too many carbs. I was buzzing. I am sensitive to carbs so I need to find a way to bring them down in this one. Otherwise it’s a great smoothie.
We love Kombucha here so this was an easy one to make. Peaches and lime was a nice combo. I do feel like this was a bit high in sugar content. But tasty.

I really enjoyed this yummy flavour combination! I used a cup of Gingerade kombucha (which added a nice zing!), 1/2 peeled small lime, 1/2 cup fresh nectarine, 1 cup frozen peaches, and a block of frozen spinach. I always add a bit of water to clean out my blender container and thin out the smoothie consistency. I drank half as described, and then added hemp protein powder to the other half, which was not as good. The protein powder I have definitely changes the flavour and is a bit gritty. I wonder how this would be with chia & flax seeds and hemp hearts, or the SGS protein powder. Fun end to wonderful 10-day challenge – thanks SGS team!
I used ginger kombucha and omitted the coconut sugar rim. I really liked this recipe. Definitely a make again. and will be trying new combinations. I’m hooked!
This was not as bad as I thought it would be. I’ve never had Kombucha. The coconut sugar on the rim helped with the taste. The recipe in the Challenge pdf did not state to juice the lime, so I added 1/2 lime without the peel.
I had to use a substitute for kombucha so I used water and a little leftover coconut water. Peaches and limes are 2 fruits that I really like so that was good for the taste. I could’ve made the smoothie a little sweeter. I will definitely try this again and make some adjustments.
I blended the entire lime into the smoothie…peel and all. Smoothie was very tangy, but refreshing. I used ginger kombucha and frozen peaches. Will try other combinations as this would be a great mocktail! Would not suggest this for a morning smoothie though–a bit too tart for first thing! It was fun to serve with the sugar rim in fancy glasses!
Great tasting!! This is in my top four.
Great taste!
This is another great recipe to add to my must make again list. For the 10 day smoothie challenge this is a tie for the #1 slot. Your choice of flavors for the kombucha can change up the flavors. I have a case of Ginger-lemonade Kombucha from Costco and it paired extremely well with the fruits and lime. Yum, yum, more please!
This smoothie introduced me to kombucha. I used organic kiwi strawberry kombucha with a kale and spinach combo. I also used turbinado cane sugar instead.. It was good ! I will try this again.
Definitely not my favorite out of the 10 day challenge. I really think this would be better with the kombucha substituted for something else. The recipe also did not specify what flavor of kombucha in the challenge guidebook, so I chose a pineapple peach figuring it is close to the recipe. FYI- if you have a blender that seals while it blends, it will go everywhere once you open it because of the carbonated kombucha.
I wasn’t able to get kombucha, so I used coconut milk for the liquid. It was cool and refreshing.
I made this smoothie with a couple of tweaks…I didn’t have Kombucha so I used Almond Milk & I also added plant based protein powder & I thought it needed a little more something, so I added a couple of ice cubes of Pomegranate juice (from my pomegranate tree!). Delicious!
Subbed coconut water for kombucha
I really liked this one. I’ve never had kombucha before.
Refreshing summer flavors. Delicious. I did not add coconut sugar since I don’t have any.
I would have never thought to blend with kombucha. I used a lemon ginger flavour and made this as a smoothie bowl with mostly frozen peaches but some frozen mango and kale instead of spinach. Also added oats, matcha, flax seeds, and chia seeds. Topped with coconut sugar, shredded coconut, hemp hearts, and granola. Made a very tasty breakfast!
