How Does Gundry MD Bio Complete 3 Work?
Gundry MD Bio Complete 3 contains strains of healthy probiotic bacteria similar to the ones that live in your gut, which help optimize digestive health. Rebecca Ditkoff, MPH, RD explains:
"Probiotics are the 'good' bacteria that live in our guts and promote healthy digestion and also give our immune systems a boost."
The Bio Complete 3 Gundry MD prebiotic fiber feeds the probiotics so they can proliferate, killing harmful microbes in the gut to balance the microbiome.
This may help promote regular, healthy bowel movements, ease symptoms like bloating, constipation, gas, and diarrhea, and optimize digestion.
Bio Complete 3 also contains postbiotics that help support the immune system, sharpen cognitive function, reduce inflammation, optimize metabolism, and boost energy. A scientific article in Critical Reviews in Food Science and Nutrition by Amin Abbasi, et al discussed the potential use of postbiotics in the treatment of gastrointestinal disorders.
The fiber in the formula both supports gut health and helps with weight management by keeping you feeling full and decreasing total calorie intake. Some research indicates that supplementation with prebiotics and probiotics may help with weight management.
A longitudinal study published in Scientific Reports by Nayera E. Hassan, et al concluded that supplementation with prebiotics and probiotics on a weight loss program helped positively alter the gut microbiota and improve results.
What Are the Key Ingredients?
These are some of the primary active Gundry MD Bio Complete 3 ingredients:
Acacia Gum:
The gum from the acacia Senegal tree is rich in prebiotic fiber that helps balance the gut microflora to improve digestion.
In addition, it helps keep you feeling full to promote satiety and decrease calorie intake, supporting healthy weight management.
An editorial and review in the International Journal of Health Sciences by Ahmed A M Elnour, et al discussed the prebiotic potential of acacia gum in supporting gut health.

Tributyrin:
This postbiotic is a triglyceride that combines butyric acid and glycerol. Tributyrin helps support the immune system, strengthen the gut barrier, improve metabolic health, and enhance digestion.
A study of mice published in PLOS ONE by Ning Yang, et al concluded that Tributyrin alleviates gut microbiota dysbiosis to repair intestinal damage.
Bifidobacterium Bifidum:
These healthy probiotic bacteria proliferate in the gut, killing harmful microbes and balancing the microbiome to help optimize digestion and ease issues like gas, boating, and constipation. Probiotics may also support healthy weight management and immune function.
A research review published in Frontiers in Bioengineering and Biotechnology by Jun Chen, et al explored the potential of bifidobacterium in treating human diseases.
