Supergut Review: A Detailed Look
Supergut is a dietary supplement company whose healthy snack alternatives are designed to promote gut health.
The brand was founded by Marc Washington and focuses on clinically proven ingredients and science backed formulas.
Supergut claim their line of shakes, bars, and prebiotic fiber mix can help balance blood sugar, stave off hunger cravings, and improve overall gut health.
As new research continues to come out about the importance of a healthy gut microbiome, and its impact on everything from mental health to obesity, more and more food products are rebranded as “gut healthy.”
Below we take a closer look at Supergut to see if their products live up to the company's claims.
Understanding the Gut Biome
The gut microbiome consists of trillions of microorganisms, fungi, parasites, viruses and bacteria residing in our gastrointestinal (GI) tract.
Keeping this ecosystem healthy is vital as it's involved in digesting food, making nutrients, supporting the immune system, and brain function.
In a healthy person this symbiotic system maintains both good and bad bacteria without any issues.
However, when this balance is disrupted due to infection, poor diet, medications, or other lifestyle factors then dysbiosis occurs and makes the body more vulnerable to disease.
Maintaining a healthy gut microbiome includes having a diet rich in:
- Foods high in prebiotic fiber: garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas, and seaweed, fruits, vegetables, beans, and whole grains.
- Fermented foods - these contain beneficial live active cultures and can be found in: kefir, yogurt, pickled vegetables, tempeh, kombucha tea, kimchi, miso, and sauerkraut.
- Seafood with Omega-3 Fatty Acids - good sources include wild caught salmon and sardines.
- Polyphenol Rich Foods - Some examples include berries, nuts, and olive oil.
- Foods High in Vitamin D- Good options include trout, eggs, vitamin-D-fortified milks, and mushrooms.
On the other hand, some of the most harmful things to beneficial gut microbiota include:
- Refined sugars
- Factory farmed meat
- Refined grain
- Artificial sweetener
- Fried foods
How Does Supergut Work?
The stated key goal of Supergut products is to provide customers with the daily nutritional requirements of prebiotic fiber.
This type of fiber passes through the body undigested and promotes the growth and activity of beneficial gut bacteria.
Prebiotic fiber can only be broken down by enzymes from microbiota found in the colon.
When it undergoes fermentation, short chain fatty acids are released, subsequently lowering the pH of the colon and limiting the growth of certain harmful bacteria. 
Furthermore, according to Supergut, these short chain fatty acids (such as butyrate) can stimulate hormones responsible for insulin, inflammation, appetite, and immune responses.

Supergut state that their foods provide satiety, help balance blood sugar sustain energy, and that you can expect to see instant benefits that improve over time with sustained use of their products.
After a few weeks customers can experience improvements in health, mood, regularity, metabolic health, and sleep.
Finally, after several months of regular usage benefits might include sustaining a healthier stable weight, reduced blood sugar, and a balanced immune response.
On Supergut.com there are links to research supporting the selection of Supergut’s ingredients. They also point to a clinical study that was conducted specifically on their product.
While many supplement makers will point to research conducted on certain key ingredients that they use, few have an actual placebo-controlled, double blind study supporting their claims.
In this case, "Supergut Prebiotic Shakes" were actively tested in a study of 192 participants with type II diabetes.
Study researchers found that, on average, the group receiving Supergut:
- Had a -0.7% reduction in blood sugar
- 3lb weight loss
- 86% participants reported improvement in at least one overall health marker
- 60% reported improvement in1 or more digestive health marker
This study was published in the Journal of Diabetes, Obesity and Metabolism.

Supergut offers a 30-day risk free guarantee on their shakes and the fiber mix. They state that if you're unsatisfied with a product you can send it back for a full refund.
For Supergut bars the company requests that you first try 3, and if you are not happy include a photo of the remaining bars when you contact customer service.
Potential Side Effects
In general, Supergut products should not cause issues for most people.
Their products do not contain gluten, though they are not certified gluten-free. Supergut shakes use dairy-sourced protein, unless you are choosing their vegan options.
Overall, consuming resistant starch is not much different from consuming fiber found in many foods and, as such, side effects are expected to be minimal.
If you are changing from a very low fiber diet, taking a fiber supplement with beta glucan may cause nausea, bloating, gas, or diarrhea in some people. 
As with all supplements it's best to slowly introduce Supergut into your diet to see how your body reacts.
