Supergut Prebiotic Bars & Shakes: The Good, The Bad, and The Questionable

If you’re looking to level up your metabolism, I get why Supergut has caught your attention. They market Supergut bars as “Nature’s Ozempic.” That’s a bold claim.

Supergut promises a metabolic makeover, all thanks to the power of resistant starch and boosting your GLP-1. Beyond the Supergut Prebiotic bars, they offer shakes and a GLP-1 Boosting Prebiotic Mix. The shakes boast similar ingredients to the bars, while the prebiotic mix lets you sprinkle their resistant starch blend into anything you want. But are Supergut Prebiotic bars really a revolutionary metabolism booster or just another overpriced, overhyped letdown?

Look, their science is interesting, BUT – and there’s always a big but – I’m here to tell you that Supergut isn’t quite the gut-health miracle it’s cracked up to be.

1. The Good (Let’s give credit where it’s due)

According to Dr. Mark Hyman, it will help you feel full, balance blood sugar, and boost good gut bacteria.

Resistant starch can definitely help you feel fuller longer, and the protein in Supergut products boosts that effect. Of course, everyone’s different, and it won’t magically erase all your cravings – but it’s definitely a powerful tool to help manage your hunger.

Resistant starch, as a prebiotic, can cause some initial bloating in certain sensitive individuals. In most users, this will pass, and is worth enduring it for long-term gut health benefits, BUT for those with IBS, prebiotics can be especially problematic, as noted by Erin Harner, Registered Dietitian Nutritionist. While I personally didn’t experience bloating with Supergut, it’s something IBS sufferers should be aware of.

2. Excess Fiber Can Cause Constipation

If you’re prone to getting blocked, increasing your fiber will probably help, but it’s not a sure thing. In most users, resistant starch makes you more regular. The critical piece here is to make sure you increase your water intake—that’s what helps everything move smoothly.

3. The Bad (And there’s a lot of it)

Sweet Deception

Supergut tries to pull a fast one with “healthier” sweeteners – allulose, rebaudioside (a highly processed form of stevia), a big whomp of erythritol and an even bigger one with Maltitol.

Sugar alcohols like these are tricky because while they have fewer calories than regular sugar, they can totally mess with your blood sugar and gut health, potentially counteracting the benefits of that resistant starch. To top things off, erythritol has recently been linked to increased stroke and cardiac risks, according to Stanley Hazen (MD, PhD), a cardiologist at Cleveland Clinic, Ohio.

4. The Ugly (U-G-L-Y You Ain’t Got No Alibi)

Okay, let’s get into why Supergut left a bad taste in my mouth……To make the resistant starch and prebiotic fiber palatable, Supergut had to resort to using many unhealthy artificial ingredients. Unfortunately, this is ultra-processed food. /p>

Palm Oil: Yikes

We’re supposed to be fixing our guts with this stuff, not trashing the planet. Why palm oil, Supergut? According to the World Wildlife Fund, palm oil has a terrible impact on the environment leading to soil and water pollution. Not to mention, it’s terrible for your health and can lead to liver and heart disease.

Ultra-Processed Vibes

Sorry Supergut, but with ingredients like glycerin, and a bunch of other extracts and flavors, this is far from the whole-food simplicity they hint at in their marketing. While it’s probably a step up from a Snickers bar, this isn’t exactly the same as eating a banana.

Pricey AF

These things are damn expensive and not that big.  The bars are $49 for 12 bars ($4/bar!) The shakes are $59 for 14 servings ($4.20/shake!) The prebiotic mix is $35 for 15 servings ($2.33/serving!) Let that sink in. It’s great that they’re trying to innovate with gut-healthy ingredients, but your wallet will take a major hit.

5. Nature’s Ozempic? Not So Fast…

Supergut likes to compare itself to those expensive Ozempic injections, with all the buzz about GLP-1. They’re not entirely wrong – this hunger-control hormone is naturally produced, and certain foods (especially those with prebiotics) can trigger your body to make more. But calling Supergut the natural equivalent of a potent prescription drug is a seriously BOLD claim. You won’t see the same dramatic weight loss as you might with Ozempic.

Supergut could potentially help with cravings and blood sugar control, but it’s not a miracle cure. If you’re managing diabetes or pre-diabetes, ANY change in diet that impacts your blood sugar needs to be discussed with your doctor. Supergut, despite their claims, isn’t a replacement for medical advice.

Yes, prebiotics are fantastic for your gut health, and that can have positive impacts on things like appetite and blood sugar over time. But that’s a far cry from the pharmaceutical-strength effects of Ozempic. Are people actually buying into their marketing? It appears that way:

On second thought, maybe not everyone is buying it:

6. The Verdict is Out on Taste (Let’s get to the sentencing)

I only had a chance to taste the Peanut Butter Chocolate bar (at $50 bucks a box, it would have been nice to have a variety pack). It had a powdery, chalky texture, similar to what you get with many protein powders. The peanut butter flavor itself was weak and artificial tasting. The bar was quite sweet, reminding me more of a candy bar than a healthy snack. That’s what you get with multiple artificial sweeteners added. The macros aren’t terrible – 150 Calories, 8g fat, 10g protein, 1g sugar, 10g fiber, 4g net carbs – but it didn’t hold me over for more than a couple of hours. On the plus side, I didn’t experience any bloating or stomach cramping after eating it. But I’m not the only one who wasn’t a fan. One reviewer on Amazon didn’t mince words. Amazon review of Supergut prebiotic bars. But the bad taste left in people’s mouths wasn’t just due to the flavor of the bars. Check out this cringeworthy Reddit response a user left to someone who asked, “Has anyone tried SuperGut?”

The Takeaway
Supergut’s got the science part down – resistant starch and gut health are legit. But don’t expect their products to be some magical metabolic cure-all. Think of them as a potentially helpful snack, not a replacement for a healthy diet. Just be prepared – they’re pricey, and those processed ingredients and sweeteners might leave you unsatisfied.

Want a REAL FOOD gut-balancing Bar? You’re in the Right Place

If the Supergut price tag made you wince, guess what? We created our own bar – Human Food Bar – because we wanted a convenient way to get more resistant starch in our diets, and the options on the market frankly sucked.

If you’re serious about changing your gut health game, better options exist. And if you’re keto or watching your sugar intake, we’ve got some alternatives for you there, too. check out our reviews on some of the best low-carb protein bars.

Human Food Bar is inspired by how hunter-gatherers ate. It’s made with whole-food ingredients, no weird science experiments, and it tastes delicious. It has the right balance of resistant starch, protein, and healthy fats to curb those cravings. Want to give it a try?



Are Supergut bars gluten-free?

While Supergut bars don't contain any gluten ingredients, they are packaged in a facility that processes wheat. This means there's a risk of cross-contamination, so they cannot be labeled as 100% gluten-free.

Are Supergut Prebiotic bars good for weight loss?

Supergut bars might help with weight loss efforts due to their resistant starch and protein content, which can increase feelings of fullness. But everyone’s results will vary so these bars won’t replace a balanced diet. While Supergut bars could be a helpful tool for someone looking to lose weight, they’re not a magic solution.

What are the side effects of Supergut?

The most common side effects of Supergut are bloating and gas, as your gut bacteria adjust to the prebiotic fiber. Some people might experience blood sugar spikes due to the sweeteners, and those with IBS or digestive sensitivities should proceed with caution.
