Bio Complete 3 is our first formula of its type to combine probiotics, prebiotics, and postbiotics into one single capsule. That’s why I call it a ‘complete’ gut health formula. However, we always recommend getting these specialized compounds into your gut daily.†* - Dr. Gundry

Bio Complete 3 works to support easier digestion, better weight management, more energy, and less unhealthy cravings by using what I call the "3-Pronged Defense" to gut health:
Boost your probiotic levels, so you have an abundance of good gut bacteria. Boost your prebiotic levels, so your good gut bacteria have the proper fuel to thrive. Boost your postbiotic levels, so you can enjoy an "ironclad" gut lining (and help combat issues such as low energy and cravings for unhealthy food)
Some people consider Bio Complete 3 to be a powerful gut cleanse program to help restore their gut and support healthy digestion. Bio Complete 3’s proprietary formula contains quality prebiotics, probiotics, and postbiotics. Together, these essential components help support your digestive health and can help you achieve your gut health goals.
Some users report feeling noticeably smoother digestion, less cravings, along with an increase in energy, vitality, and muscle strength in their first week of use. However, the most results were reported after consistent use over the course of 4 weeks and beyond.
Bio Complete 3 contains only the best ingredients. The formula is tested for quality at an independent, 3rd-party laboratory. We recommend consulting with your own health care provider before beginning any new program.
We understand that individual bodies can react differently to the very same compounds. Even though we think everyone can benefit from the powerful probiotics, prebiotics, and postbiotics in this formula, we are aware that results can vary. So, if you're unsatisfied with this product for any reason whatsoever after a full 90 days of use, we will return your purchase price, hassle-free.
