One of the First Supplements to Combine Prebiotics, Probiotics, and Postbiotics in One Daily Digestive Health Formula

LOS ANGELES, May 29, 2026 /PRNewswire/ — In honor of World Digestive Health Day, Gundry MD® is spotlighting one of its most popular gut health supplements: Gundry MD Bio Complete 3™. Designed to support digestive health, gut microbiome balance, healthy digestion, energy levels, and regularity, Bio Complete 3 stands out as one of the first supplements to combine prebiotics, probiotics, and postbiotics into one comprehensive daily formula.†*

As conversations around gut health, bloating, microbiome balance, digestive wellness, and immune support continue to grow worldwide, Gundry MD Bio Complete 3 has become a go-to supplement for individuals looking to improve digestion naturally and support overall wellness from the inside out.†*

Developed by renowned cardiothoracic surgeon and bestselling author Dr. Steven Gundry, the formula is designed to help nourish beneficial gut bacteria, support healthy bowel movements, reduce occasional bloating, and promote better nutrient absorption using clinically studied ingredients.†*

Unlike traditional digestive supplements that focus on only probiotics or fiber, Bio Complete 3 delivers a complete “three-pronged” gut health approach.

What Is Gundry MD Bio Complete 3?
Gundry MD Bio Complete 3 is an advanced gut health and digestive support supplement designed to help support a healthier microbiome, smoother digestion, improved regularity, and overall digestive wellness. Unlike traditional probiotic supplements that focus on only one aspect of gut health, Bio Complete 3 combines prebiotics, probiotics, and postbiotics into one comprehensive formula to support the digestive system from multiple angles. This daily supplement was created to help nourish beneficial gut bacteria, support the gut lining, improve nutrient absorption, and help reduce occasional bloating and digestive discomfort.†*

What Is the Difference Between Prebiotics, Probiotics, and Postbiotics?
Prebiotics, probiotics, and postbiotics each play a unique role in supporting digestive health and maintaining a healthy gut microbiome, but they work in very different ways.

Prebiotics are specialized types of fiber that act as food for beneficial gut bacteria. Instead of directly adding bacteria to the digestive system, prebiotics help nourish and support the healthy bacteria already living in the gut. This can help promote microbiome balance, digestive regularity, and overall gut wellness.

Probiotics are live beneficial bacteria that help support a healthier gut microbiome. These “good bacteria” may help maintain digestive balance, support immune health, improve regularity, and reduce occasional bloating or digestive discomfort. Probiotics are commonly found in fermented foods and dietary supplements.

Postbiotics are beneficial compounds created as probiotics break down fiber and nutrients during fermentation. One of the most important postbiotics is butyrate, a short-chain fatty acid that helps support gut lining integrity, digestive comfort, microbiome balance, and intestinal health. Postbiotics are becoming increasingly recognized as an important part of overall digestive wellness.

Together, prebiotics, probiotics, and postbiotics work synergistically to help support a healthier digestive system. Prebiotics help feed beneficial bacteria, probiotics help populate the gut with healthy microbes, and postbiotics help support the gut environment itself. This is why more consumers are now searching for comprehensive gut health supplements that contain all three components together.

Gundry MD Bio Complete 3 Ingredient Pros
One of the biggest advantages of Gundry MD Bio Complete 3 is that it offers a more comprehensive approach to digestive health than many traditional gut health supplements. Instead of focusing solely on probiotics, the formula combines prebiotics, probiotics, and postbiotics together to help support the microbiome from multiple angles. The inclusion of clinically studied ingredients like Sunfiber and tributyrin helps distinguish the product from basic probiotic formulas, while the shelf-stable Bacillus Coagulans strain is designed to survive stomach acid more effectively than many common probiotic strains. The formula also supports multiple digestive health goals at once, including gut lining support, bowel regularity, microbiome balance, nutrient absorption, and occasional bloating relief. For consumers looking for an all-in-one digestive wellness supplement, Bio Complete 3 provides a convenient daily solution without requiring multiple separate products.*†

Gundry MD Bio Complete 3 Ingredient Cons
While Gundry MD Bio Complete 3 contains several clinically studied ingredients designed to support digestive wellness, results can vary from person to person depending on factors such as diet, lifestyle, microbiome health, and consistency of use. Some individuals may not notice immediate results and may require several weeks of daily use before experiencing the full digestive health benefits. Additionally, because the formula uses premium ingredients and advanced gut health technologies, it may be priced higher than standard probiotic or fiber supplements on the market. Individuals with existing medical conditions, digestive disorders, or sensitivities should also consult a healthcare professional before beginning any new supplement routine.*†

What Makes Gundry MD Bio Complete 3 Different Than Other Products?
What sets Gundry MD Bio Complete 3 apart from many other digestive health supplements is its comprehensive “three-layer” approach to gut health support.

This combination allows the formula to support digestive health before, during, and after the digestive process. Additionally, the inclusion of tributyrin, a butyrate-supporting postbiotic, helps support gut lining integrity and digestive balance in a way that many traditional probiotics do not. Combined with clinically studied Sunfiber® and a shelf-stable probiotic strain, Bio Complete 3 was designed to support microbiome diversity, digestive comfort, regularity, and overall gut wellness in one daily supplement.*†
