An imbalance in your gut flora is one of the root causes of many health issues. You may already know that the body comprises billions of good bacteria responsible for complete well-being. So when there are more bad bacteria than good bacteria in your gut, you are easily prone to a leaky gut that kickstarts a chain of other health problems. And the reason is that 70% of your immunity is managed by your gut, as stated by the makers of Bio Complete 3.

    The Science Behind the Bio Complete 3 supplement Formula

    One of the most adaptable dietary fibers is Sunfiber® and there are various reasons for it. Generally, dietary fibers are not much helpful to treat diarrhea although they might help recover from constipation. Sunfiber® is backed by research to increase the levels of Lactobacillus and Bifidobacteria, which is vital for healthy gut flora. 

    Studies also show that Sunfiber® enables easy movement of food through the gut, which helps in easy digestion and prevents loose stools. 

    Next, we have Bacillus Coagulans (ProDURA®) in Bio Complete 3 pill, which according to a 2013 study is resistant to heat more than 2 other competitors. It is proven to be easily adaptable to extreme environments such as stomach acid, bile, etc. Both human and animal studies indicate that Bacillus Coagulans (ProDURA®) boost the presence of good bacteria in the gut and assist in various other functions such as cholesterol regulation, vaginal health, lactose breakdown, etc. 

    When you break down Tributyrin (as CoreBiome™), you get butyrate which is known to be the most essential as well as the basic nutritional necessity for optimal gut function. CoreBiome™ is the first tributyrin that is commercially used and is popular for its effects on treating bloating, indigestion, and other issues related to unbalanced gut flora. It is also the only tributyrin that has clinically substantiated bioavailability. Studies show that Tributyrin (as CoreBiome™) provides nutritional support to the entire digestive system and strengthens the gut lining that prevents the entry of bad bacteria into the bloodstream.
