So does Gundry MD Bio Complete 3 live up to these claims? To answer that question, we’ll thoroughly review the product formulation based on what the current medical research has found about the benefits of these ingredients. 

We’ll also share some Bio Complete 3 reviews from real customers so that you can get their take on the results of this supplement. 

What Are The Gundry MD Bio Complete 3 Ingredients?

The Bio Complete 3 formulation contains a “3-pronged blend” of prebiotics, probiotics, and postbiotics. Below we’ll give you the details on each one. 

Prebiotic Blend

Prebiotics are non-digestible fibers that serve as “food” for the beneficial bacteria in the gut, thereby promoting digestive health. 

There’s two prebiotics in Bio Complete 3: Acacia Gum (from Corebiome) and SunFiber Guar Fiber. 

An 2021 in vitro (test tube) study published in the journal ACS Omega found that acacia gum “significantly promotes Bifidobacteria proliferation similar to fructo-oligosaccharides (FOS) while inhibiting the Clostridium histolyticum group, commonly associated with gut dysbiosis.”

In simpler terms, this means acacia gum helped the good bacteria (Bifidobacteria) grow, and stopped the bad bacteria (Clostridium group) that can cause problems in the gut.

The other prebiotic in Bio Complete 3 is SunFiber, a patented fiber derived from guar gum. There are some studies that demonstrate the health benefits of guar gum. 

For example, in a 2023 study published in the Journal of Clinical Biochemistry and Nutrition, participants took 3 to 5 grams (g) of partially hydrolyzed guar gum dietary fiber. Results of this study found that guar gum improved gut health, sleep, and motivation among healthy subjects. 

However, we noticed there’s a very low dose of guar gum in the Bio Complete 3 formula. 

While we don’t know the exact amount in Bio Complete 3, the label states that the total combined amount of acacia gum and guar gum is only 450 mg — so that means the amount of guar gum is significantly lower than the dosage used in the aforementioned study. 

Probiotic Blend

Probiotics are live beneficial bacteria that support the balance of the gut microbiome, aiding in the digestion and absorption of nutrients. They can contribute to a healthy and balanced gut environment.

There’s two probiotic strains inside Bio Complete 3: Bacillus Coagulans (ProDura) and Bifidobacterium bifidum. 

ProDura is a patented strain of the probiotic Bacillus coagulans. ProDura, being a spore-forming bacterium, is believed to retain a natural protective coating that remains inactive until it encounters the suitable conditions of heat, pH, and moisture in the large intestine.

  1. coagulans has been studied in both animal and human trials. Results of these trials suggest that this probiotic may help with IBS, constipation, and intestinal gas. 

Bifidobacterium is one of the most common probiotics found in the human gut, and supplementing with this probiotic may offer several benefits. 

For example, a 2021 publication in the journal Frontiers in Bioengineering and Biotechnology shares that Bifidobacterium may help reduce inflammation, help the body fight infection, relieve constipation, and alleviate symptoms of lactose intolerance.

Postbiotic Blend

The postbiotic in Bio Complete 3 is called tributyrin, a triglyceride composed of three butyrate molecules. Butyrate is a short-chain fatty acid that serves as an important energy source for the cells lining the colon.

According to a 2023 publication in the peer-reviewed journal PLOS One, tributyrin “has a key role in anti-inflammatory and intestinal barrier repair effects by slowly releasing butyric acid”.

What Are The Benefits of Gundry MD Bio Complete 3?

After reviewing the various ingredients and probiotics used in Gundry MD Bio Complete 3, we’ve summarized the benefits you may notice with this product:

Balanced Microbiome

The purpose of the pre- and probiotics in Bio Complete 3 is to help maintain the balance of the gut microbiome by preventing the overgrowth of “bad” bacteria. A balanced gut microbiome is crucial for maintaining overall health, supporting digestion, immune function, and even mental well-being.

Reduce Intestinal Inflammation

The inclusion of the postbiotic tributyrin in Bio Complete 3 may help to reduce intestinal inflammation and promote intestinal barrier repair. Ultimately, this means it may help alleviate discomfort, promote proper nutrient absorption, and support overall gut health.

What Are The Side Effects of Bio Complete 3?

Like any dietary supplement, there is a possibility of experiencing side effects. 

The side effects that are typically associated with pre- and probiotic supplements include stomach upset, gas, diarrhea, or bloating. Based on the Bio Complete 3 reviews that we read, there are customers who have experienced these side effects from this product.

Always consult with your healthcare provider before incorporating any supplements into your routine to ensure they align with your individual health needs and medical conditions.
