What’s with the “Protein Soda” Trend—and Is It Safe?

You’ve probably seen it on TikTok: someone pouring Diet Coke into a shaker bottle, tossing in a scoop of vanilla protein powder, giving it a shake (usually followed by foam everywhere), and calling it “protein soda.”

It’s fizzy. It’s sweet. It’s packed with protein. But… is it actually a good idea? Or just another social media experiment that’s gone too far?

First, What Is Protein Soda?

At its core, protein soda is exactly what it sounds like: a bubbly drink that gives you a hit of protein along with the familiar fizz of soda. 

People are either making it themselves at home or buying pre-made versions from brands hopping on the trend.

The Homemade Version

This is the one going viral: grab a flavoured protein powder (think caramel, vanilla, or fruit) and mix it into your favourite diet soda. 

Some people say it tastes like a float or a melted ice cream soda. Others say it tastes... not great. (You be the judge.)

The Store-Bought Kind

There are also ready-to-drink options hitting the shelves. For example:

• Clear Protein Soda from Clean Simple Eats gives you 20g of whey protein isolate in a can. It’s caffeine-free, low-lactose, and made with natural ingredients.
• Arla Foods Ingredients has a version with 10g of protein, zero sugar, and a light, refreshing taste.

These are made to be more gut-friendly, with simpler ingredient lists and clear labelling.

Why Is Everyone Drinking It?

There’s a reason why protein soda is blowing up right now.

And it’s not just because it looks fun on camera.

We Love a “Functional” Drink

People are moving away from plain old hydration. They want their drinks to do something more than just hydrate.  To help them recover post-workout, keep them full, or boost energy. 

Protein soda promises all of that, in a convenient, on-the-go format.

Protein Is Having a Moment

From protein bars to protein cereal to protein ice cream… protein is everywhere! 

It could be a magic ingredient for building muscle, managing weight, and staying full longer. Soda just happens to be the latest variation of it.

It’s Quick and Easy

No blender. No prep. Just twist, sip, and go. 

For busy students, gym-goers, or anyone who doesn’t love eating three full meals a day, this is an easy protein fix.

Social Media Loves It

Be honest…watching someone mix fizzy soda with a creamy powder is kind of weirdly fascinating. Delicious or disgusting, it’s hard to look away.

But… Is It Safe?

Here’s where things get interesting. Like most trends, it really depends on how you’re doing it.

The Store-Bought Stuff

These are generally safe for most healthy adults. They’re made with care, tested for quality, and labelled with all the info you need. 

If you enjoy the taste and it doesn’t mess with your stomach? Go for it.

The DIY Version

This is where it gets a little messy. Mixing protein powder with diet soda at home can cause some less-than-fun side effects:

Your Gut Might Not Love It

Diet soda is already a mix of artificial sweeteners and acids. Add in protein powder (especially whey) and it can lead to bloating, gas, or even diarrhoea for some people.

It’s a Bit of a Chemical Cocktail

Both soda and protein powder are acidic. Combined, they can irritate your stomach or cause heartburn.

It’s Super Processed

Homemade protein soda falls into the ultra-processed category. 

That doesn’t mean it’s toxic, but it’s probably not something your gut wants every day.

Too Much of a Good Thing?

If you’re adding protein soda to an already high-protein diet, you might end up overdoing it. 

That can stress your kidneys, throw off nutrient balance, or just leave less room for whole, fiber-rich foods.

What Do Experts Say?

Most nutrition experts would agree: protein is important, but balance is more important.

Supplements like protein powder can be helpful, but they’re just that: supplements. 

If they’re prioritising protein soda over whole foods and it’s causing discomfort, it’s worth rethinking.

So, here’s what to keep in mind:

• Commercial protein sodas: Generally fine in moderation.
• Homemade ones: Proceed with caution.
• Digestive drama: A sign to slow down.

Final Thoughts

Protein soda is fun. It’s trendy. It’s one of those “why not try it once?” kind of things.

If you’re into it, cool. Just pay attention to how your body responds. And if your gut says, “No thanks,” that’s worth listening to.

No need to fear it. No need to follow the crowd either. Like with most things in food and wellness, you get to decide what works for you.

And hey…sometimes plain old water and a protein-packed snack does the trick just fine, too.
