     The Triple‑Biotic Difference: Prebiotic + Probiotic + Postbiotic 

    Most gut supplements only deliver probiotics. Bio Complete 3 brings three critical gut‑health nutrients together. Feed good bacteria, replenish living cultures, and deliver postbiotic metabolites to support your gut lining all at once.

    • 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.t*

    • 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.t*

    • 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.t*

       A Letter from Dr. Gundry 

      Hi. My name is Dr. Steven Gundry and I’m so excited you’re here! If you want to improve your health, get in shape, and achieve a long, happy life…

      Let me be the first to welcome you. (You’re most certainly in the right place!)

      I’ve worked in medicine for over 50 years and am proud to be known as one of America’s preeminent heart surgeons.

      My colleague Leonard Bailey and I performed more infant and pediatric heart transplants than anyone else in the world. I’ve also had the privilege to operate in over 30 countries – including charitable missions to China, India, and Zimbabwe.

      Then in 2001, I met a so-called “hopeless” patient suffering from heart disease. By making some unusual changes in his diet — almost by chance — this man made a complete turnaround.

      In working with him, I made some major discoveries that changed the course of my career. I learned about some key nutrients that are deficient in the American diet, as well as some staple household foods which are actually toxic to the human body.

      When I first met this “lost cause” patient, I was dangerously overweight myself. I had high blood pressure, bad cholesterol, digestive issues, and my body felt weak.

      I ran 30 miles a week and ate a low-fat, vegetarian diet. Yet no matter what I did, the weight just wouldn’t budge. I started to worry that my best years were behind me…

      Hey, that’s me — Dr. Steven Gundry.

      I’m a husband, father, cardiac surgeon, medical innovator, author, and founder of Gundry MD.

      But by following my new research – I was able to lose 70 pounds in just one year AND become stronger, healthier, and more active than ever.

      So shortly afterwards, I left the operating table to do something very different…

      I founded medical institutes in Palm Springs and Santa Barbara to help people avoid surgery.

      (That’s why my colleagues now call me “No More Mr. Knife Guy.”)

      Since then, I’ve been fortunate to help tens of thousands of patients turn around a whole host of health issues — including low energy, obesity, heart disease, autoimmune conditions, diabetes, and more.

      And Gundry MD is a revolutionary expansion of that mission.

      Before

      After

      Simply put... 

      Our goal is to help dramatically improve your health, happiness, and longevity through the amazing power of nutrition.

      I don’t care what other doctors may have told you in the past. You don’t have to accept ‘slowing down’ as a normal part of aging. And Gundry MD is here to offer HOPE to anyone struggling with fatigue, weight issues, digestive discomfort, sore joints, aging skin, or general health decline.

       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.

      What is Holobiotics?

      Your body and its “bugs” working in tandem to help give you optimum health.

      Think of your body like an apartment complex. 

      You’re the landlord, and the trillions of tiny bugs are your tenants. 

      Some of those bugs are “good” tenants. They help manage your digestion, boost your energy production, and power your immune system to keep you from getting sick.

      But some of those bugs are “bad” tenants. These include pathogens that can cause illness and harmful yeasts that can wreck your digestion or make you gain weight.

      The lectins, sugars, artificial sweeteners, and other additives found in many modern foods can jeopardize your microbiome and keep you from feeling your best.

      To help restore your body to optimum health and wellness, you need to be taking care of your good bugs.

      And every product from Gundry MD is designed with this purpose in mind. Whether it’s a nutritional supplement to help your gut bacteria thrive…

      A skin treatment to support the healthy bacteria that live on the outside of your body…Or any of the other cutting-edge innovations currently in our catalog.

      And that’s holobiotics in a nutshell. It’s all about taking care of your good bugs. Because if you take care of them… they will take care of you!
