Bio Complete 3 Review: Legit or Scam?

Reviewopedia staff  -  Updated:  July 18, 2023


Bio Complete 3 is a dietary supplement created by Dr. Steven Gundry, a doctor who is well-known for his promotion of gut health supplements.

Gundry states he believes that beneficial microbes in your digestive tract are the key to not just good digestive functioning, but overall health, too.

This new product claims a variety of benefits.  But does Bio Complete 3 really work? Here’s what you need to know.

What is Bio Complete 3?

With active ingredients like sunfiber, tributyrin, and Bacillus coagulans, this supplement is intended to improve gut health by providing a number of benefits.

Tributyrin is a unique form of butyrate, a fatty acid that beneficial probiotic bacteria release as they break down starches.

While you’ve likely heard of probiotics, butyrate is similar - except it’s what’s called a post-biotic.

Sunfiber, on the other hand, is a pre-biotic, or a food that is required to sustain the probiotics in your body. 

Pre-biotics help support the bacteria, or bacillus coagulans, which provide a whole host of benefits to your body while they work. 

These benefits include stopping food cravings, eliminating excess gas and bloating, fighting leaky gut, improving your ability to lose weight, fighting fatigue, and more.

One bottle of Bio Complete 3 contains a 30-day supply, with two capsules meant to be taken daily.  The dosage is the same regardless of your weight or age.

Cost and Price Plans

On you can buy one bottle of Bio Complete 3 for $69.95, including shipping.

You can also get a discount if you make a larger order ( 3 bottles for $188.85 or 6 bottles for $353.70). 

You can also sign up for a subscription plan.

When you do this, you will receive an automatic monthly shipment of Bio Complete 3 in addition to unique discounts that lower the price to $41.95 per bottle (or more, if you buy in packages of three or six).

Customer Reviews & Complaints

One complaint about Bio Complete 3 is that there can be some pretty extreme side effects when you first begin taking these supplements.

This is particularly true if you take more than the recommended dosage, as the capsules are specially formulated and consuming too many can have a heavy impact on your digestive tract.

Symptoms such as bloating and gassiness are not uncommon when you begin to take fiber and probiotics, so bear this in mind.

While these symptoms are not usually serious, they can be unpleasant to deal with. 

GundryMD currently has an A+ rating with the BBB. 

The company has an average rating of 4.31/5 stars from over 2,500 customer reviews there, with 66 customer complaints filed in the last 12 months.

All supplements bought through the Gundry MD website are backed by a 90-day money-back guarantee.

If you aren’t happy with your purchase, you can call the customer support phone line to start your refund process. 

You can buy Bio Complete 3 directly from the manufacturer as well as on Amazon.

The Bottom Line

To decide if Bio Complete 3 is right for you we recommend getting in touch with your doctor first to help you make the decision.

There is plenty of research demonstrating that probiotics and similar supplements can help regulate your digestive functioning and lead to ancillary benefits, like weight loss.

However, there are just as many studies that show that some of the ingredients in Bio Complete 3, like butyrate, can harm your intestinal barrier in high doses.

There are some claims that butyrate can contribute to obesity instead of helping with weight loss.

So, while taking supplements like Bio Complete 3 can be helpful for some people, for others, it might not be very effective.

FINALLY back to passing SOLID waste
August 9, 2022

Thanks to the myriad T2D and BP meds that I am on - my GI tract was a MESS...

in LESS than a week (YMMV) things are back to normal. Post meals, my guts sounded like a sub going below crush depth - no more.

"Loose Stool" was THE understatement of the year - also, NO MORE...

I'll be keeping this on repeat buy TYVM!!

Thank You Walt... I'm looking to be the "test bed" my wife is the patient. My health is good and improving it can't hurt me. I don't take a lot of medicines or follow fads, so I'm looking at the science aspect. We bought the Vital Recharge and it was an instant change in energy and mental acuity.

This is a product not to miss out on!
August 9, 2022
So far, so good! I feel good and believe the product provides what it offers! Anything from Dr Gundry is an excellent product. The Bio Complete 3, I will remain on! Thanks so much!

well I take a lot of supplements.. for my age at 66 I'm in good shape.. I go kayaking a lot.. do lots of renos.. I bought a lot of supplements from you guy's through out the years.. I really think that's why I feel young and lots of energy.. I truly believe your product has lots to do with me being in good physical shape.. I am a teacher in martial arts and kickboxing.. but now that I'm retired it's kinda hard to buy supplements with hardly any income..

Gradual improvement and no side effects.

Early days yet but my reflux and gut “ comfort” is improving. Relief from constipation is better too.

Unfortunately my appetite is improving but it is good to enjoy food again.

I’ll happily keep you updated in a week or two’s time.

Nothing to note yet.

BioComplete 3 three weeks in...
August 8, 2022
It's been about three weeks since receiving BioComplete 3. We haven't noticed a huge difference yet, except BM's have been more consistent. Have not lost any weight yet and haven't noticed any other benefits although my wife and I just got over COVID again so we will see. We are both taking it and we will give it until the 90 days to assess before we request return.

I love Bio3 Complete
August 7, 2022
Bio3 Complete is a little pricey, but I really don’t have to take anything else but that. So overall I’m saving money.

I am confident in sharing with others .

It works!

The bio complete is the first supplement I could use that eliminated my IBS. I’ve been taking it every day for 30 days and my stomach has gone down I’ve lost weight and I feel so much better thank you so much.

Feel Better with Bio Complete 3 even after your first Bottle!
August 6, 2022
I have just finished my first Bottle of Bio Complete 3 and already feeling better than when I started. I look forward to continue to feel even better than I do now!

August 6, 2022
When is the best time to take this? I saw nothing that advised when and how to take.

It’s not immediate yet after a few weeks I see a great improvement!
August 6, 2022
I have been taking the Bio complete 3 for a few weeks now and at the beginning I didn’t notice any difference. Still suffered bloating and even indigestion and heartburn. But now I’m noticing I can eat without bloat and my system is more regular and feels more complete after I empty my bowel. I will continue to take these pre pro and post biotic and hope to see even more results down the road like having my body actually absorb nutrients from food so I can absorb vitamins and minerals better.

A couple of days after my first 4 dose of Bio Complete I already feel better on my stomach, that gurgling sound on my gut although still there is already not much and my bathroom problem is back to normal in every morning but I don’t know if that total restore has something to do with it, and my question to you now Doc is how long I should take this supplements of yours ? Thank you

Hard to say, it's so soon starting, as I only received them a week ago, however I seem to have more energy which was unexpected. And I'm not feeling bloated anymore which is nice.
