    Bio Complete 3 has made me feel so much better than I have felt in years. The constant bloating I have felt for years is gone. The bloated appearance of my stomach has gone away. My energy level has increased significantly. I can honestly say that it has been a long time since I have felt this good. I would recommend this product to anyone who has been suffering with an overall feeling of poor health. All this and I have only been taking Bio Complete 3 for approximately two weeks. Great product.

    This supplement has definitely increased the frequency and quantity of bowel movements. I think I am eating less and yet going to the bathroom more! There are way fewer cravings for sweets or other junk food. So far, so good.

    5 out of 5 Feeling of well-being

    Patricia Hauser

    I just turned 68 and have always struggled with regularity and cravings. Even with drinking a lot of water, pushing veggies & fruit, and resorting to a stool softener, I had occasional normal stools. I started taking Bio Complete 3 and within 24 hours there was a change. I had a normal stool unlike any before and my body just felt better overall. It continued. Then I noticed I stopped craving sweets. I’d look at my chocolate stash and could take it or leave it. I just felt better mood wise and my waistline started becoming more defined as I lost a couple pounds (not trying at all). All that with taking a half dose! I am increasing it to 3 capsules daily and will progress to 4. I was cautious how it would react in my system. All I can say is I wouldn’t want to live without my Bio Complete and look forward to future improvement. Thank you Dr. Gundry. It does everything you said it would. YOU are the BEST!

    Hi, I am happy to report thus far the product has improved my bowel movements and settled down my gut pains. A littlle bit of flatulence but at least i can pass wind now.

    5 out of 5 No more Food Coma


    After a few days of using Bio Complete 3 I noticed that I wasn’t so tired after a meal. It had gotten so bad that I usually avoided driving after eating for fear of falling asleep. Now I can eat a full meal and still be wide awake and active. I love this product.

  12. Cathy Shelmidine

    5 out of 5 Very satisfied with the Biocomplete 3

    Cathy Shelmidine

    I have many issues with my gut and am sensitive to wheat and other additives. I was hesitant at first to try any product. However, after talking with one of the female representatives, I decided to try both the probiotics and the Total Restore. My gut seems to be more regular. I also find the videos very informative about what we are putting into our bodies. After the holidays I plan to incorporate a more strict diet as suggested by Dr Gundry.

  13. Jason Jones

    5 out of 5 Great product

    Jason Jones

    I take these once a day and they seem to make me feel better. I recently took a vacation for 3 weeks and forgot them and I can feel the difference without them.

    Kim H

    Have suffered from chronic constipation my whole life! I can go as long as a week without a bowel movement. I have used every available remedy on the market with no consistent relief. Without going into further detail of my GI history all I can say is by day 3 of taking BioComplete 3 I have had a NORMAL bowel movement every morning!! I have since ordered PreBioThrive which arrived today! Beginning Dr. Gundry’s diet program as well!! I feel as if I am getting a new lease on life. Will
    keep you posted on my journey to a healthy and vitalized life.
    Many thanks!!

    I’ve tried 2 other Gundry products….but not nearly the results of Bio Complete 3. By the 2nd day, 2 movements per day……no more gas, bloating, chronic constipation. I’ll be using this from now on…..73 years and counting.

  24. Susan Becker

    5 out of 5 it is working

    Susan Becker

    I intentionally started slowly one pill in morning for 1 week then 2 pills AM and PM. Gut is much more comfortable with so much less gas. Have solid bowel movements for first time in years. Can control bowel movements well enough that travel is much more easy. No longer have to know the locations of bathrooms within two hours. No weight loss yet but am hopeful.
    Started slowly 1 pill in AM for one week then added second pill in the PM. Gas has diminished and movements are more solid. No longer have to find a bathroom with in two hours.
    It is working.
    It is working, much lower gas, more solid movements. No longer have to find a bathroom every two hours.

    David Consoli

    I am very delightfully surprised at the results experienced since taking Bio Complete 3. I literally, overall, feel better. And, I have peace of mind that I will have regular bowel movements and I know I will not be constipated while taking BC3 everyday.
    Before starting to take the BC3, I would tend to go days without a movement and, of course, I would be constipated. What a relief now not to worry about constipation and the straining.
    Thank you for Bio Complete 3. I will be ordering regularly, no pun intended, from now on.

    I find my bowel movements are easier and smoother. In the past if I’d eat chocolate I’d be constipated soon after. I’m finding with Bio Complete this isn’t happening any more. Thank you Gundry MD

    It is comforting to know beyond any doubt, that the the probiotic you are taking has what you need. I already take vital reds every day, start my day with shot of olive oil, so everything was working well before I added Bio complete 3.

  56. herbsfo

    5 out of 5 This product provides fast, noticeable improvements


    If you know your body and you pay attention to it, you’ll likely experience documentable positive change from this product. My partner and I began recognizing subtle improvements within a couple days and the positive change continued over the following weeks.
    Think it’s all in your head?? Nope.
    I wasn’t paying attention and forgot to reorder after finishing a two month supply. We had to go without for several days and it was actually uncomfortable – bloating, gas, irregularity, overall cranky. The refills arrived and within 24 hours we started to feel the improvements again. I know it sounds odd but we both could actually feel the improvement.
    I understand no product works for everyone but this product is absolutely worth a try, because if it works for you – you will love it. If not, you have the Gundry guarantee. […]

    5 out of 5 Best Gut supplement available


    This is hands down, without a doubt the best gut support supplement I have ever taken. I have been a regular user of Lectin Shield for a number of years which I rate highly. But, I had tended to use Lectin Shield on “as needed” basis taken before a meal with questionable ingredients. I take Bio Complete 3 daily. Frankly, it has been life changing. Any residual gut issues I still had after following Dr Gundry’s diet advice for over 4 years now have evaporated. I take it about one hour after getting up and on an empty stomach. No acid reflux, no discomfort and the daily toilet visit is trouble free. My energy levels are like i am back in my 20’s. I crave caffeine much less. Please keep this in stock. Will be taking long term.

    5 out of 5 Life changing product


    I am in my 50’s. I have been suffering from severe fatigue, brain fog […] I was fed up! I just wanted to feel better. I started researching my symptoms to find the causes and to find a solution. I decided to try Bio Complete 3. Wow! What a life changing product! I noticed gradual improvement starting the first week. After the second week, I was having more “active” days. It was taking me less time to recover after an “active ” day. I have been taking this for 1 month and I have energy […] I am able to do gardening! I am able to work a full day! I am able to take walks and exercise! Life changing.

  63. Cary Swenson

    5 out of 5 Great Product!

    Cary Swenson

    I’ve been on this for one month and my regularity is substantially increased. I will stay on this product for at least 6 months because it takes time to turn around nutritional deficiencies. Since you can’t always “feel” how a product is working, I want to build up good gut health as I’ve been told about 80% of your immune health is in your gut [..] I trust Dr. Gundry and am willing to give this product a good try.

    I’ve been taking Bio Complete 3 for several months and noticed so many positive results; clear skin, less water retention, regularity, better sleep, less overall fatigue, less joint pain, less cravings, etc. Then, I ran out. Oh, what a mistake. I miss this product every day and am so anxious to receive my order. I’m now on the subscription plan. Great stuff, well done Dr. Gundry!

    5 out of 5 IT REALLY WORKS

    Christopher L

    As a wheelchair bound 55y/o male, proper digestion is important. This, along with proper eating habits, has enabled me to enjoy meals without feeling worn out afterwards as it synergistically works with my other suppliments.

  69. Jennifer

    5 out of 5 Positive and palpable changes!


    My system is so incredibly sensitive to literally everything. I have tried other probiotics which had caused skin or stomach issues. Bio Complete 3 is different. Results manifested around the 1.5 month mark: 1) My BMs became awesomely predictable (2x/day), 2) I had more energy–no more slogging up a flight of stairs, 3) Far less bloat meant a trimmer midsection which had plagued me since my mid-40s, and 4) My skin looks amazing–clear and bright! I’ve been using Bio Complete 3 for over 4 months now. Paired with clean, lectin-free eating and exercise, I am looking and feeling the way I used to in my early 30s:) I absolutely love this product!

  72. Ashley Thompson

    5 out of 5 I was skeptical to try...I am amazed at the results!

    Ashley Thompson

    Everything it says can happen, has happened for me – and very quickly. I noticed less bloating, and regularity within the first 2 days. I crave sweets, but that has disappeared in the past week. No more indigestion and discomfort after meals. I have never experienced this much energy in my life. I start my day at 5 am, and work a fairly physical job. Normally by 4 or 5 pm – I don’t have much left in the tank. Not the case any longer! This has absolutely changed my life!

    Bio Complete is a good product because your confidence can be assured with the knowledge that the bases are covered when it comes to your body’s needs in the digestive area. It’s nice to know when you don’t have to take three separate supplements to cover the issues with life’s complicated system in the digestive arena. It’s all working for you daily with this product.

    5 out of 5 Substantial Benefit


    While I saw benefit from using the Total Restore, I decided to try Bio Complete 3. I was surprised to get immediate benefit. Regularity and feeling lighter have become the norm which was not the case previously. I feel I have discovered a positive step with Bio Complete towards great gut health that even the best diet alone might not achieve. Its great to find a product that is essential to feeling good.

    I have just started using Bio Complete 3 and am experimenting with a diet. I ordered this because I am aware of the importance of probiotics and suspect that I have been deficient. I discovered that a friend has been taking it and has great confidence in Dr. Gundry. I am already enjoying some relief in the absence of stimulant laxatives.

    Helps greatly in reducing sugar cravings and seems to work symbiotically with your other products. I have been taking four each morning so I’m glad that I returned to the site to discover the recommendation to split the dosage am/pm. This should be included on the label. My belly fat has literally melted away in a matter of months.

  112. Marian

    5 out of 5 Such A Great Product


    I had used it before, then ran out and didn’t re-order. Have been using various other Dr. Gundry products and like them all… I just can’t help it. Feel so good about them! I was noticing with a great deal of extra stress going on in my life that my stomach was a bit out of sorts. Decided to add back the Bio Complete 3… took about 3 days for me to start feeling much better and more calm, especially my stomach. So, here you have it. These are the best products I’ve ever used. Try some of the other ones too!

  138. Brenda Williams

    5 out of 5 Working , even better with Vital Reds

    Brenda Williams

    I have been taking the Bio Complete 3 for several weeks now, feeling a positive difference. Few days ago, I started taking the Bio Complete 3 in the mornings with my breakfast as well as drinking the Vital Reds. I feel this has greatly improved the impact on my gut since Vital Reds also contains Probiotics. I do not buy juices, so the Vital Reds does make a great juice drink and knowing it is working with my Bio Complete 3. I can submit another review on both products when I am further into the time frame of using both products. I do feel MUCH better.

  139. Debra Smith

    5 out of 5 Stomach problems improving daily.

    Debra Smith

    Only have had it for three weeks, but I don’t have stomach acid at night when I want to sleep. I am regular now and I have been able to cut down on sweets I do not crave them. I have six months worth of tablets I hope to feel like a new person then. I also use Lectin Shield. I’ll be 70 next year.

  140. Brenda Stevenson

    5 out of 5 I believe in Bio Complete 3

    Brenda Stevenson

    After using this product for three weeks, I have definitely noticed some weight loss around my stomach, better consistent bowel movements and more energy. I had reached a plateau In my weight loss plan and just couldn’t loose any more weight. Fasting was not doing the trick either. So I decided to give this product a try and am thrilled with my results. I have lost five pounds in three weeks and still find it hard to believe! I am now increasing my weight bearing exercises since I do seem to have better energy, and now I’m also building muscle and better bone density I hope.

  141. Julie Allen

    D Ray

    I was very skeptical and wasn’t expecting the results that were promoted in Dr. Gundry’s video. Since i have been working from home for the last few weeks, I feel more energized than I thought I would, not snacking and feeling full most days of the week. I need to do better with watching sugar intake (it’s in everything!!!) and trying to keep in natural. I do feel better from a gut health standpoint and have noticed less bloating. I am 1/2 way through my 1st bottle and it’s going great so far.

    I take BC3 along with total restore. Have been on for a month and the biggest difference is the amazing sleep, amazing mornings, combined with amazing natural energy. This truly works, I feel great. I have since purchased vital reds, Calm Probiotic Cream, untox, and botanical cleanser because Dr Gundry gives such great deals often. I always buy in bulk, and try the offering because I know how much he cares and I can feel my health getting better, you can’t fake that feeling of happiness. Thank you !

What Are The Benefits Of Taking Bio Complete 3? (Gundry)†

Taking care of your gut is absolutely key to your overall health. Nearly all of your internal systems are tied to gut health – from digestive health to the heart, brain, skin, immune system, and more. If you can achieve balance in the gut, you may achieve more optimal health in your other systems, too.1,2

With Bio Complete 3 on your side, you can look forward to results such as:

  • An easier time achieving your weight loss goals*
  • An abundance of youthful energy*
  • Support for digestive issues*
  • Easier, more regular bathroom visits* 
  • Cravings for unhealthy foods feeling like a distant memory*

*Every individual is unique. As such, your results may vary.

How Does Gundry MD Bio Complete 3 Work?

Your gut is host to trillions of bacteria – some good and some bad. Balance between good and harmful bacteria is indispensable to optimal gut health and overall human health, too.3†

Bio Complete 3 helps your gut achieve and maintain microbiome balance with a blend of probiotics, prebiotics, and postbiotics.

Probiotics provide you with an abundance of good gut bacteria.4 Prebiotics feed the beneficial bacteria and give them the fuel they need to thrive.5 Postbiotics promote your butyrate levels to help support a strong, healthy gut lining.6 This may help with issues low energy and cravings for unhealthy foods.*

By boosting your probiotic, prebiotic, and postbiotic levels, you may enjoy better digestion support and weight management, increased energy levels, and less unhealthy cravings.7†* 

*Every individual is unique. As such, your results may vary.

What Are The Main Ingredients In Gundry MD Bio Complete 3?

There are three main ingredients in Bio Complete 3:

  • Sunfiber®
  • Bacillus Coagulans (ProDURA®)
  • CoreBiome™ (standardized to 30% Tributyrin)

The ingredient Sunfiber® is a gentle soluble dietary fiber that works as a prebiotic.8 Bacillus Coagulans is a resilient, spore-forming probiotic.9 CoreBiome™ is a postbiotic that can boost butyrate and help support the intestinal lining.10,11†

How Do I Take Bio Complete 3?

Your path to better gut health support couldn’t be simpler. Just take two capsules twice per day, ideally before a meal.

Bio Complete 3 is formulated to absorb quickly and get right to work in your gut — to help  you feel a boost in energy and well-being.*

It’s important to take your Bio Complete 3 every day on a consistent basis. Taking it with breakfast and then again with dinner may help you develop a healthy habit that soon becomes routine.

*Every individual is unique. As such, your results may vary.
