Welcome to my Bio Complete 3 review.  

Gut health plays an essential role in overall health. After all, some people believe it’s the body’s second brain.

The gut microbiome is where you can find most bacteria, viruses, and yeast in the body. An imbalance in the gut means there are more negative bacteria than positive ones. 

This can lead to health issues like poor digestion, decreased immune system, and trouble losing weight. 

As a registered dietitian, I may recommend including pre and probiotics to help establish a healthy balance.

Bio Complete 3 is a supplement that contains both pre and probiotics. On top of that, it contains postbiotics, which is a term you don’t hear that often. So, it might support the immune system and digestion. 

However, since it only contains one strand of probiotics, it leaves you wanting more.

About Gundry MD

Gundry MD is a supplement company responsible for creating supplements like Bio Complete 3 and MCT Wellness. Its founder is Dr. Steven Gundry, a former heart surgeon. 

His supplements aim to improve human health, happiness, and longevity. 

Dr. Gundry creates natural products that align with his philosophy of holobiotics. This is the belief that you can obtain ultimate health when you learn to cooperate with the bacteria inside the body. 

When there are more good bacteria than bad bacteria, they take care of your health. 

What Is Bio Complete 3?

Bio Complete 3 is a gut health supplement that claims it can increase energy levels, improve digestion, reduce cravings, and make it easier to achieve weight loss. 

The formula contains pre and probiotics and something called postbiotics, which I will explain later in the article. 

Who is Bio Complete 3 for?

Bio Complete 3 is ideal for people that want to improve their gut health. 

Gundry MD Bio Complete 3 might be the solution if you have poor digestion, are constantly getting sick, and have trouble losing weight due to increased cravings. 

However, like any other supplement, remember that everyone might have a different outcome. 

Things to Consider Before Buying Bio Complete 3

Before investing in this supplement, here is a list of those things you need to consider before purchasing Dr. Steve Gundry Bio Complete 3. 

Probiotic Strains

gundry md bio complete 3 considerations

There are several types of probiotics. They help repopulate your gut microbiome with bacteria that may bring health benefits. 

Bio Complete 3 only offers one probiotic strain. Even though it may produce several benefits, a probiotic should have at least five different strains for optimal benefits. 

So, if you want a supplement with more than one strain, this is not the option for you. 

Pill Form 

Bio Complete comes in pill form. The label advises you to take four capsules per day. 

While some people don’t have trouble swallowing pills, others don’t like it or are too busy to remember to take them multiple times daily.

If that describes you, I’ll share some alternatives later in this review. 

Nutrition and Exercise

Finally, before buying a supplement, ensure you have the right foundations. With this, I mean committing to good nutrition and exercise. 

If you take a supplement to fix your gut but continue eating junk food and sugars, you won’t get the desired results. 

So, make sure you are eating enough fruits, vegetables, whole grains, lean protein, and healthy fats throughout the day, along with an active lifestyle. 


Each bottle of Bio Complete Three contains a month’s supply and costs $69.95. 

As you consider if this is right for your budget, bear in mind that coming up, I’ll show you how to save by buying in bulk.

Bio Complete 3 Features

Moving along in this Bio Complete 3 review, we’ll talk about all those features that make this supplement stand out. 

Reduces Cravings

Having cravings is a pain, especially when you’re trying to lose weight. Cravings can become intrusive thoughts. In the end, it might lead to eating large quantities of it to satisfy your needs. 

Consuming large portions of food leads to a caloric surplus which can lead to weight gain. 

So, in the end, you are getting farther and farther away from your goals. 

One of the benefits of Bio Complete 3 is that it contains CoreBiome and SunFiber, which can help reduce cravings. 

This might help you to stop thinking about food all day and focus on what is really important. 

Improved Digestion

gundry md bio complete 3 features

If you feel that no matter what you eat, you seem to get gassy and bloated after every meal, you are not alone. And, let me assure you, it is a very uncomfortable feeling. You feel like a balloon is inside you, making it hard to move or breathe. 

Bio Complete 3’s probiotic content claims it can help you improve your digestion. That way, you won’t have to dread eating food since you’ll get rid of that nasty bloating and gas. 

Boosts Gut Health

The gut can help modulate the immune system and aid in digestion. If you find yourself getting sick very often, one of the problems might rely on your poor gut health. 

Bio Complete 3 is a unique three-pronged blend of probiotics, prebiotics, and postbiotics. They all work together to promote a healthy gut improving your immune system and digestion. 

Helps With Weight Management

It’s very challenging to lose weight. You might have tried everything from changing your diet and exercise with no luck in getting the results you strive for. 

Probiotics might aid in weight loss. When there is a healthy balance of the gut microbiome, it can lead to a reduction in inflammation and promote weight loss (as long as you lead a healthy lifestyle). 

Bio Complete contains probiotics and prebiotics that you might need to boost your results. 

Does Bio Complete 3 really work?

You might want to know if Bio Complete 3 works before you purchase it. This is difficult to answer since everyone can get different results from the same supplement.

That said, it seems likely that Bio Complete 3 could help improve gut health for some. 

However, since it only has one strand, I advise consuming other probiotics to get other bacteria to populate your gut. 

Bio Complete 3 Ingredients

To determine the functionality of Bio Complete 3, we must analyze the ingredients they use. 

Here is a list of those ingredients from Gundry MD Bio Complete 3: 

  • Tributyrin (as CoreBiome™) 
  • Sunfiber®
  • Bacillus Coagulans (ProDURA®)
  • Other Ingredients: microcrystalline cellulose, hydroxypropyl methylcellulose, sunflower Oil, fatty acids Esterified with glycerol, magnesium stearate, silica, and maltodextrin.

The doses stated below are for four capsules

Tributyrin (as CoreBiome™)(1,000 mg)

CoreBiome is a well-known postbiotic, which might be a new term for you. 

So, before we dig into the benefits of CoreBiome, let’s talk a little about postbiotics. 

Probiotics are the healthy bacteria in your gut, while prebiotics is the food that feeds that bacteria and keeps it healthy. 

Postbiotics are the waste that remains after the body digests the pre and probiotics. 

There are different postbiotics, such as vitamin K, vitamins from the B complex, amino acids, and other molecules, such as healthy fats. 

CoreBiome is a form of Tributyrin, which is a short-chained fatty acid. 

It seems that it can help the gut microbiome to produce butyrate. 

Butyrate might help reduce inflammation, boost the immune system, decrease cravings, and support blood sugar levels. 

Sunfiber® (200 mg)

Sunfiber, a type of fiber that comes from the guar plant, is a probiotic that helps feed the bacteria in the body. 

It is a low FODMAP fiber, meaning people with IBS can consume it without having negative side effects. 

Additionally, it can help reduce the number of harmful bacteria in the body. It also might help regulate blood sugar levels and reduce weight thanks to its satiating effect. 

Bacillus Coagulans (ProDURA®)(16 mg)

Bacillus Coagulans is a type of probiotic. It can help reduce symptoms of IBS, help fight constipation, and decrease gas

One of the benefits of this type of probiotic (ProDURA) is that it has a strong outer shell that can withstand harsh environments. 

A thing to note about the supplement is that it is not clear how many live bacteria it has. Since it comes in milligrams, we cannot determine if it has an effective dose of colony-forming units (CFU). 

Other Ingredients

The main “active” ingredients in the supplement are the three mentioned above. However, there are other ingredients that the company uses to modify the texture and stabilize the formula. 

Here is a list of the other ingredients in Bio Complete 3: microcrystalline cellulose, hydroxypropyl methylcellulose, sunflower Oil, fatty acids Esterified with glycerol, magnesium stearate, silica, and maltodextrin.

If you find yourself having side effects (which I’ll share later), you can cut the dosage by half to allow the body to get used to the supplement. 

Real Customer Bio Complete 3 Reviews 

So, what are people saying about the product? Here, I’ll go over some Bio Complete real reviews. 

On their website, the supplement has a rating of 4.8 stars from 530 reviews. 

On the other hand, on their Amazon website, they have a 3.9-star rating with over 3,000 thousand reviews. 

Let’s check out the positive things people are saying about Bio Complete 3. 

  • Many people report having no more stomach issues after taking the supplement.
  • Some users report fewer leaky gut symptoms. 
  • Users report having less bloating and gas. 
  • According to some users, it helps reduce their cravings. 
  • People report having more regular bowel movements. 

Here’s a consensus of the negative things people are saying about this supplement. 

  • Some people state that the price is slightly expensive. 
  • A small number of customers didn’t notice as big of improvements when taking the supplements. 

“In only a couple weeks my bloating gassy feeling [has] much improved. Gout, achy joints and even dry eye condition seem improved. I confess I cleaned up my diet some as well so I can’t say it was all due to these supplements. The 3 in one approach is simple like me. I am really hopeful of continued improvement.”

  • Arnold 

“I see a lot of comments complaining about unpleasant symptoms while taking this but the important thing to remember is the bad bacteria must be cleared out as the new good bacteria set up colonies. The sicker you are, the more bm’s you experience, means your guy biome needs this rebalancing badly. 

This product has helped me and my son recover from leaky gut syndrome that had us both seriously ill and taking on new allergies rapidly. Doctors kept giving antibiotics which is the exact opposite of what we needed to heal.

I know everyone’s gut biome is unique but trust me when I say I have studied the crap (excuse the pun) out of this topic reading medical journals and learning everything I can from functional medicine doctors. I also use food as medicine. You cannot continue eating trash food and expect probiotics to save the day.

I highly recommend this product but get it on Dr. Gundry’s website. It is waaaaay cheaper than these prices.”

  • Kristen

“I am not sure about this product yet. I have been using [it] since last summer. I got a better price from the product’s actual website after my initial Amazon purchase. It helps me stay regular (I am in my 60’s) so I use it. 

As far as all the claims made go I am not sure but I also lost about 25 lbs. since taking this product (I was in possession of a “spare tire”) but I can’t promise the Bio-Complete caused this as I also made small dietary changes. 

However, on the chance that this product did in fact cause the weight loss I shall continue to use it and if for no other reason than the fact that I have been “regular” since taking it then so be it.”

Supports gut health.

The biggest benefit you can obtain from this supplement is that it might support gut health. The gut has several roles in the body, as we’ve mentioned throughout the article. 

So, when the gut functions properly, the rest of the body is in tune as well. 

Prevents you from eating unhealthy junk food.

One of the health benefits of Bio Complete relies upon its ability to reduce cravings. Its high fiber content can help increase fullness levels which reduces cravings. 

Fewer cravings lead to a reduction in eating unhealthy food, which might promote overall wellness and weight loss. 

Boosts the immune system.

bio complete 3 benefits

The gut modulates over 70% of the immune system. Thanks to its probiotics, prebiotics, and postbiotics, Bio Complete 3 can help promote good gut health. 

Promotes smoother digestion.

Finally, having healthy bacteria helps promote good digestion. The bacteria in the gut help digest food, so it helps reduce the symptoms of bloating, gas, and diarrhea. 

Potential Side Effects of Bio Complete 3

Bio Complete 3 seems to be a safe supplement to take. But, like with any other supplements, you might experience side effects. 

According to the reviews, the most common side effects are bloating, gas, stomach cramps, and diarrhea. 

If you start getting any of these symptoms, stop the supplement or reduce the dosage until your body gets used to it. 

Also, make sure to always check with your doctor whenever you start a supplement to determine if it’s suitable for you.

Bio Complete 3 Verdict

We’ve reached the end of this Bio Complete 3 review. 

Bio Complete 3 is a supplement that contains prebiotics, probiotics, and postbiotics. This powerhouse combination can help improve gut health, leading to better digestion and a boosted immune system.
