    I definitely have less bloating and my bowels are more regular with no constipation. I feel more energetic and a lot less sluggish. I,ve shared my bottles with 3 others and am hopeful bio complete 3 will do wonders for them too.

  12. 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.

    excellent! i feel better since i had this product

  15. lilmangoma

    5 out of 5 Life changing product


    I am in my 50’s. I have been suffering from severe fatigue, brain fog, muscle and joint pain. It was to the point where I was in bed more days than I was up. I had gone to several doctors with the same results-sending me to another doctor. 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, no muscle and joint pain (even when it rains). I am able to do gardening! I am able to work a full day! I am able to take walks and exercise! Life changing.

    I have had horrible gut issues for years. Within a couple days I noticed the difference. I am feeling so much better & my stomach & bowels have improved tremendously.

  19. 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.

    5 out of 5 Ran Out!


    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!

  24. Christopher L

    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.

  25. 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!

  26. Roger Keller

    Biocomplete 3 is a wonderful supplement to take, especially if you want to regulate digestion and elimination.

  28. 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!

  29. Peter Quieros

    5 out of 5 Excellent Product

    Alma Winberry

    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.

    I take the 24 strain Probiotic and Prebiothrive as well as this BioComplete 3 and my digestion and bowel movements are humming along! I have not experienced such smooth functions in my life. Bloating is totally gone and stool is no longer hard as a rock.

  51. Michael

    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.

    Judith Weiss

    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.

    5 out of 5


    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.

  68. 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!

  69. Jeff

    Amy Cieslak

    I’m over-the-moon delighted with my results using Bio Complete 3. I’ve been taking it daily and I’m feeling so much better in my overall health.

I guess my gut buddies are rewarding the rest of me by giving me more spunk & vitality throughout each day to stay on top of living my youthful life. Thank you for this excellent product!!!

  94. 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.

  95. 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.

  96. 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.

    I have been using product for about a month now and found that I no longer feel full all the time. Stomach is flatter as well. It also seems that I am losing my craving for sweets. I will continue to purchase this product.

    I’m gluten and lactose sensitive. Especially with gluten, it’s difficult to be completely away from it. With Bio3 complete, I felt the different in my digestive system instantly! And must I say, it has reduced my apetite for heavier foods which is a plus! God knows how much I love to eat ;D

    5 out of 5 Feeling great after taking Bio Complete 3!

    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.

    5 out of 5 Great product and great product line


    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 !

    I wasn’t suffering any bloating or other gut problems. I started taking Dr Gundry’s Bio Complete 3 simply because I read his article on the importance of a healthy gut. It made sense to me, and since taking it, I am way more energized and enjoy being out in my garden and with my horses. I think it’s the energy that it has given me that would be the most important factor of taking Bio Complete 3.

    Lynn Martinek

    I had been taking a Probiotic for several years that was recommended to me at my local store when I caught Dr. Gundry’s online video. I thought his thinking made sense so I ordered a three bottle starter and within the first week I felt the difference. I can’t imagine going back to the Probiotic I was taking, it is obvious that it’s not enough. Bio Complete 3 really is complete I’m convinced that Dr. Grundry has gotten it right. It works. It really, really works!

  169. David Vargo

    5 out of 5 Won't Start My Day Without It

    David Vargo

    I have been taking Dr. Gundry’s products for about 3 months now. I started because I saw an ad on Facebook and listened to Dr. Gundry’s video. What he said made so much sense to me and I could tell he was sincere and honest. Even though the cost of the products was a little more than I would ordinarily spend on myself, I decided to give it a try… Within days I started to feel better and I have not missed a dose of BioComplete 3. I have added, just because I want to, Prebio Thrive, Lectin Shield, 24 Strain Probiotic…There is a calmness inside my gut that I forgot could be experienced. I’m very pleased with Dr. Gundry’s products. They have helped me a lot. Frankly, I can’t imagine starting my day without them.

    BioComplex has changed my husband’s life. We are elderly and married after the death of our spouses. My husband had terrible digestive tract issues when we married. . With proper food and supplements it improved immediately but, always fragile. Since BioComplex his whole bowel routine is regular and without scary fluctuations. No one is happier than he. He credits me with his good fortune. I credit the proper balance of needful supplements that have renewed his bowel function. Smart man to listen to his wife.

Taking care of your gut is absolutely key to your overall health.

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.*
