I was looking for a effective probiotic for my gut health. I came across Dr Gundry Bio Complete 3 and decided to give it a try. This is my second month and I'm delighted with the results of regular BMs. My system is no longer sluggish so therefore I have more energy.

What's Inside

Potent, science-backed ingredients

About 70% of your immune system resides in your gut, so taking care of it is absolutely key for maintaining good overall health. Bio Complete 3 helps support a healthy gut and digestive lining with prebiotics, probiotics, and postbiotics.†︎︎*

  • Lectin-free

  • Sugar-free

  • Soy-free

  • Dairy-free

  • Artificial sweetener-free

    • Postbiotic

      This one-of-a-kind postbiotic blend acts as a protective 'sealant' for your entire gut lining, to help key nutrients stay 'locked' in your gut. These postbiotics also boost energy production by supporting your mitochondrial health ... and helps keep you feeling sharp, youthful, and active.†︎︎*

    • Prebiotic

      The prebiotics in Bio Complete 3 give your probiotic 'gut buddies' the food they need to flourish and thrive inside your digestive tract... while also supporting your metabolism and reducing unwanted urges to eat sweets and junk food.†︎︎*

    • Probiotic

      These are the friendly gut bacteria that help you feel slim, energized, and active... and fend off issues like occasional gas, bloating, and uncomfortable bowel movements.†︎︎*

      I founded Gundry MD with one mission: To help dramatically improve human health.

      My research may offer a breakthrough for those of you who have struggled for years with your energy levels, your body, and your health. If you’ve tried everything and nothing has worked… I’d like to offer you HOPE.”

      Philosophy

      There’s one fundamental theme that guides my philosophy:

      Holobiotics.

      Holobiotics is based on the scientific belief that true health can only happen when you’re living in a state of cooperation with the trillions of tiny microbes that live everywhere in, on, and around your body.

         The only thing that works!

        This is the ONLY probiotic that helps keep me regular since starting a GLP-1 medication in September 2024!! In addition to digestive enzymes and a ginger supplement, my digestion has been as close to normal as I'll ever get at this age.

         Best probiotic I've tried so far

        The only time I feel regular and my gut is at peace is when I am taking these supplements! I have tried other probiotics that either didn't work or upset my GI and come back to these. These are the best, I have been using them for three years and will continue to use them.

        How does Bio Complete 3 work?†︎︎*

        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)

Together, these essential components help support your digestive health and can help you achieve your gut health goals.

        When can I expect results?†︎︎*

        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.

        Is Bio Complete 3 quality-checked?

        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.

        What if it doesn't work for me?

        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.
