If you are up to date with the latest health trends, you probably know all about probiotics. If you do not, we will fill you in. Probiotics[1] are a mixture of good bacteria that help restore your body’s balance of good bacteria. An imbalance of bad bacteria over good bacteria causes lots of health challenges. Probiotics such as Bio Complete 3, help increase your body’s population of good bacteria to fight off the bad bacteria.

The breakdown products of prebiotics help improve gut health and can make their way into your bloodstream to improve the health of other organs. Finally, postbiotics are the newest of the three in the biotics family. They are products of microbial fermentation[3] that can offer health benefits. The role of postbiotics in promoting health is a fascinating field receiving lots of attention and research. 

The unique natural cocktail that is Bio Complete 3 from Gundry MD, claims to encourage weight loss too by promoting gut health.

Bio Complete 3 Ingredients

Gundry MD Bio Complete 3 contains several natural ingredients that work together to give its health benefits. The three main ingredients[4] in Bio Complete 3 are:

  • Tributyrin (as CoreBiome™)
  • Sunfiber®
  • Bacillus Coagulans (ProDURA®)

Other ingredients present in Bio Complete 3 include:

  • Microcrystalline Cellulose
  • Hydroxypropyl Methylcellulose
  • Silica
  • Magnesium Stearate
Bio Complete 3 Ingredients Review 

Tributyrin (as CoreBiome™)

Intestinal bacteria metabolize undigested carbohydrates to form short-chain fatty acids such as acetate, propionate, and butyrate. Butyrate has a gut protective[5] function and is believed to act through anti-inflammatory and immunoprotective effects. It can also help protect your intestinal lining to prevent a leaky gut. Tributyrin supplements provide butyrate that may help you enjoy its numerous potential benefits. 

While more human studies need to be done on the benefits of tributyrin, the current animal studies show that this supplement offers several health benefits. A study[6] on weaned piglets showed that tributyrin helped improve digestion and protein metabolism. It also contributed to increased insulin, glucose, and HDL fraction. These benefits of tributyrin in weaned piglets may also translate to benefits in human subjects. 


The good bacteria in your gut need the right nutrition to thrive. That is where sun fiber comes in. It is a Partially hydrolyzed guar gum (PHGG)[7] fiber that can help restore gut microbiota balance for better gut health. It is gluten-free[8] and could potentially support weight loss. 

Fiber can help promote the feeling of satiety so that you do not overeat. Hence, fiber supplements can help with weight loss[9] by helping you maintain a caloric deficit. 

Bacillus coagulans (ProDURA®)

Bacillus coagulans are lactic acid-producing gut bacteria. Supplements containing Bacillus coagulans help restore your digestive tract’s good bacteria content. It has been scientifically shown[10] to improve bowel troubles such as irritable bowel syndrome, acute diarrhea, and colitis. 

A study on the use of Bacillus coagulans for the treatment of irritable bowel syndrome shows that it may help relieve symptoms such as abdominal discomfort and diarrhea. These effects on gut health were shown to last for up to nine months[11]. A small study showed that Bacillus coagulans can help relieve the pain and discomfort from intestinal gas too.  

Risk & Side Effect

Dr. Gundry’s Bio Complete 3 is relatively safe to use. It is completely organic and users experience few side effects with its use. Nevertheless, a doctor’s consultation is essential before you start using Bio Complete 3. Probiotics containing Bacillus coagulans are safe to use but Bacillus coagulans is still a bacteria and this might pose some health concerns in people with compromised immune systems. Your doctor will let you know if taking Bio Complete 3 is safe in your health condition.

Some users complained of side effects such as abdominal pain while using the supplement. If you experience serious side-effects with Gundry MD Bio Complete 3 use, discontinue it, and consult your physician.

How to Use Bio Complete 3?

Bio Complete 3 comes in a bottle containing 120 capsules. The Gundry MD website recommends taking two capsules twice daily. For better results, take your supplement before meals and drink lots of water too. Before breakfast and before dinner is how Dr. Gundry takes his Bio Complete 3 and you could try that routine too. The super-fast absorbing Bio Complete 3 capsules get right to work on improving your gut health soon after you take it. 

Bio Complete 3 Review: What Do Real Users Say?

Here’s what real users like you are saying:

“If you know your body and you pay attention to it, you will likely experience documentable positive change from this product. My partner and I began recognizing subtle improvements within a couple of days and the positive change continued over the following weeks.Think it is 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. […]”


“I can’t wait for 4 weeks because weeks 1 & 2 have definitely started out with a new life on the horizon!! Thanks Dr. G!”


“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.”


“Bio Complete 3 is a good product, my husband has been using it, he’s happy with what it does. I trust Dr. Gundry’s products, they do exactly what they are supposed to do.”
