Why I love the Collagen Kombucha Slushie so much!

First, it tastes amazing. Second, it combines two of my favorite things, kombucha and collagen. When you talk about the trendiest of the health trends of the last few years, those are definitely at the top.

It seems like you can’t turn around without hearing someone talk about how those things changed their life!

Believe the hype.

Now believe me, I’m a total skeptic when it comes to this kind of thing. I’ve been duped too many times, and things I try never seem to live up to the hype.

But I’ll tell you what, I use collagen AND kombucha in my everyday life because they actually do what they’re supposed to do. They make me feel good. Collagen and kombucha are two things I’ll never give up! I LOVE them.

More on that below.

Oh, and did I mention it tastes UNBELIEVABLE?! I did? Well, it’s worth mentioning twice.

I totally have a thing for mocktails. If you like this one, wait until you check out my other non-alcoholic drink recipes, like my Coconut Mojito Mocktail or my Strawberry Basil Smash!

Now let’s get back to this collagen kombucha mocktail recipe!

There are just a few simple steps to follow to make this mocktail come together!

How to make the Collagen Kombucha Slushie Mocktail:

The ingredients!

I really think simple things are the best things. Don’t you? Well, this recipe is made with FOUR ingredients. Five if you count the mint, which is totally optional. It’s lightly sweetened from the kombucha, and the almond milk makes it nice and creamy. It’s an absolutely perfect drink on a hot day. My boys (ages 3 and 6), each drank a big glass of it, and were begging me to freeze more kombucha cubes!

Just a little PSA: Don’t try to freeze kombucha in the glass bottle. It will explode in your freezer. Pour it into ice cube trays to prevent that from happening, and to also make it easier for your blender.

Now once your kombucha is frozen, just add in the fresh berries, collagen, and a little coconut cream or almond milk and blend. I used Califia Farms Better Half, which is compliant unsweetened almond milk/coconut cream. You can get it on Amazon or pick it up at Target. I love how creamy it is!

Read my Whole30 Target Grocery List post to see more of what I buy there!

In this recipe, I’ve used both GT’s Gingerberry and Triology flavors of kombucha, which are both 100% Whole30 compliant. Feel free to substitute another flavor or a different brand. I really like Humm too!

Now before you run to the store, I really want to tell you some things you need to watch out for when choosing your collagen and kombucha.

Sourcing them them wisely will help you find the best product for you!

So… what is Collagen?

Collagen is a protein our bodies make. In fact, collagen is the protein our body makes the most of, naturally. If bodies will naturally make collagen all by themselves, why do we need to supplement? Well, it’s important to note that as we age, we makes less collagen. Less collagen in our bodies can cause some issues – joint pain, wrinkles, even gastrointestinal issues.

Supplementing with grass-fed collagen peptides or bone broth collagen can help correct some of those problems.

I’ve been taking grass fed collagen for over two years, and it’s made my nails stronger, and my hair and skin healthier.

Collagen Kombucha Slushie Mocktail

I have a family member who swears it helps beef up their immune system. Another noticed an improvement in ongoing GI problems. Another says it stopped her hair from falling out. You’ll hear lots of stories like this.

But there’s research to support some of the anecdotal evidence, too:

One study found that collagen supplements “help promote joint health and potentially restore some bone density in people with osteoporosis and osteoarthritis.”

The trick is finding a great collagen to use, and then finding creative ways to take it!

Pro Tip: Take these ice cubes and add a few to a large glass, then pour seltzer over it. Holy YUM and super simple!

Here’s what you need to look for when choosing collagen supplement:

Choose a high quality, grass fed collagen source that you trust.

If it’s bovine (from cow), make sure it’s grass fed and ideally grass finished, too. There are other options like chicken and even marine collagen, which may be better suited to your dietary needs.

Try to find out the country of origin. I tend to avoid anything that’s not sourced from the US, EU, or Australia.

If it’s at all possible, choose a bone broth collagen.

Collagen supplements ain’t cheap. Whatever works with your budget is fine! BUT bone broth collagens are made from bones and processed less than those from hides, plus they’re more nutrient dense.

I highly recommend Paleo Valley Bone Broth Protein. I also like Vital Proteins Bone Broth Collagens! There is a mild flavor to all bone broth collagen powders, and they dissolve much better in hot liquids than cold.

I like to add grass fed collagen to coffee, smoothies, soups, and mocktail recipes as an easy way to get my supplement in!

For this recipe, I used classic Collagen Peptides.

Okay, now WHAT is Kombucha?

Kombucha! Yup, it’s the official drink of millennials, and is now found at pretty much every grocery store in America. People LOVE the stuff! It’s touted for health benefits and it’s really tasty and refreshing, but what is it, really?

Kombucha is fermented sweetened tea. That might sound complicated, but it isn’t.

Basically, kombucha is sugar + tea + water + SCOBY (in case you care, SCOBY officially stands for Symbiotic Culture Of Bacteria and Yeast). So the bacteria and yeast in the SCOBY will break down the sugar in the tea. It then releases probiotic bacteria, the source of all the probiotic/microbiome goodness you hear about.

The probiotics are what lead to increased gut health and a plethora of other health benefits.

Yes, I actually just used the word plethora. That might be the first time in history. But I digress.

What are the health benefits of kombucha?

You’ll hear a lot of anecdotal evidence about the health benefits of kombucha. People attribute everything from increased regularity and better immunity, to regulated blood sugar and better sleep, all to drinking kombucha. Without getting too into detail, the best way to describe how kombucha makes me feel is this: Like a friggin rock star.

Here’s a little ditty from the medical community about the health benefits of Kombucha:

Healthy bacteria in the digestive system and immune function is becoming clearer as more studies focus on gut health. If the probiotics in kombucha improve gut health, they may also strengthen the immune system.”

Medical News Today

So basically, we’re pretty sure what people are saying is true and that it’s good for you. Probiotics are linked to many health benefits, but there’s still a lot of research to be done. Collectively, I think we need to learn more about gut health.

Is kombucha Whole30 compliant?

If you’re doing a Whole30, you know you have to carefully select your food and drinks. The answer to this question is a little complicated, but yes, kombucha is Whole30 compliant, so this is a Whole30 mocktail.* Did you hear that?

Kombucha is Whole30 compliant, even though it’s made from sugar + tea!* Shocking, right? Well, I hoped you noticed those asterisks, because as awesome as it is, it’s not all that simple.

If sugar is added after the fermentation process (which is often is in some fashion), it is not compliant.

You already know how to read your labels carefully, so remember to read them when you choose your kombucha, too. For further information, read Whole30’s answer on determining whether your kombucha is Whole30 compliant.

Where to get it:

Some people choose to make their own kombucha at home! It isn’t terribly complicated, but you do need a SCOBY. If you have a friend who makes their own kombucha, just ask for a piece of their SCOBY and do some google searches for recipes. You can buy one, too. I’ve made my own Kombucha before, and it’s relatively easy, very inexpensive, and super tasty!

Of course, there are plenty of store-bought brands, too! The biggest drawback is that they aren’t cheap. Most bottled kombucha will run at least $3, sometimes up to $5 or $6. Here’s how I look at it, though: Nobody boo-hoos about somebody spending their money on a six pack of beer or a bottle of wine. I think it’s a-okay to spend some of your hard-earned money on a few bottles of kombucha!

So yeah, store bought kombucha is kind of a luxury item. Still, you’ll never find me using my spending money on fancy clothes. I’ll be buying kombucha!

Check out my Whole30 at Walmart and Whole30 at Target posts to see the compliant kombuchas and more that are found there.

Now when you make the Collagen Kombucha Slushie, there’s one VERY IMPORTANT THING YOU MUST DO. Close your eyes, imagine you’re sitting in a hammock on a beach somewhere, wind blowing softly, island music playing in the background. And then take that very first sip. It’ll make it taste better, I promise (wink).
