It's time to review Gundry MD's Bio Complete 3.
This supplement is one of the most popular probiotics.
But does it actually work or it's just a scam alert?:
- several potential side effects
- unique ingredients
- very expensive
So is this supplement really worth buying? Where can you buy it?
Well, I analyzed it in detail – so here's everything you need to know about it (+ video).
Note: This review is based on my opinion + research on Bio Complete 3.
Full Name: Bio Complete 3 from Gundry MD
Product Type: Probiotics
Best Actual Price: Around $70/bottle
Cheapest Place To Buy: Its official website
It claims that its various versions from retailers are fake – but I pretty much doubt that.
I will explain why later on.
Designed For: Promoting a health gut lining:
- improves digestive issues
- reduces cravings and fatigue
- increases general immunity
- can also help with reducing weight (in some cases)
So it has the typical benefits of probiotics – but it's also a versatile one.
My Rating: 6 out of 10
Recommended?: Not really – even though it's a good pre/postbiotic.
But as a prebiotic, I would surely not recommend it:
- pretty weak formula
- very expensive
- requires a lot of pills per day
Instead, I recommend you to go for a much stronger probiotic that also costs less.
What I Liked About It
- Reputable brand behind
- Unique formula based on trademarks
- Great as a pre/postbiotic
- Worked for enough users
- Many authentic user reviews behind
What I Didn't Like About It
- Only contains one probiotic strain
- Pretty low dose of probiotics
- Requires 4 pills/day
- Enough unsatisfied users
- Pretty high rate of side effects
- Very expensive for its value
#1 – Claims & Producer
First of all – let me give you some general things about this supplement:
- how exactly it works
- what issues it targets
- who is its producer
As I said, Bio Complete 3 is a mix of 3 blends:
- (the classic) probiotics
However – unlike most probiotic supplements, it claims to help with excess weight as well.
The explanation is simple – it reduces cravings.
Other than that, there isn't too much info about its promises.
Honestly – that's an advantage, as it's not that kind of product that claims to make miracles and actually does nothing.
So from this points of view, Bio Complete 3 looks pretty good.
2. Company Behind
Bio Complete 3's producer is a brand called Gundry MD:
- very reputable overall
- easy to get in touch with them
- lots of details on their official page
Now – this company makes several other supplements and skin products.
And in terms of reputation and trustworthiness, it looks great.
That's why I'm completely sure it's not an actual scam.
#2 – Ingredients (7 out of 10)
Honestly – this supplement's formula looks pretty disappointing to me.
It does indeed contain 3 types of ingredients – but nothing else:
- its probiotic has a pretty low dose (2 billions CFU)
- only one bacterial strain
In other words, it looks pretty good both as a prebiotic and as a postbiotic.
But as an actual probiotic, it's pretty weak.
And since it's actually a probiotic supplement – its overall formula isn't amazing.
That's why I'm not a big fan of it at all.
Still – let's take each of its 3 ingredients by turn.
1. Tributyrin (as CoreBiome™)
This trademark ingredient is responsible for the “postbiotic part”.
And it's actually what makes this supplement unique – as not many products contain it:
- it's a precursor to butyrate 
- reduces general inflammation
- can also boost immunity
Now – postbiotics are actually some last-step compounds.
Prebiotics feed probiotics, which generate postbiotics as a waste.
But despite being considered a waste, postbiotics are actually very helpful in terms of immunity.
In fact, their full benefits for human health aren't discovered yet.
However, they are surely helpful form (at least) some points of view.
As for this compound, it's the “prebiotic part” inside Bio Complete 3:
- another trademark ingredient
- soluble dietary fiber 
Now – this ingredient's #1 role is to feed good bacteria (probiotics).
Prebiotics themselves can also work if taken alone, as they feed your existing good bacteria.
However, in most cases – you probably have a lower level of good bacteria than normal.
That's why prebiotics are usually combined with probiotics.
3. Bacillus Coagulans (ProDURA®)
As you can guess – this is the actual probiotic inside Bio Complete 3:
- helps with diarrhea and bloating
- can benefit people with IBS/IBD 
- reduces intestinal irritation
Now, this bacterial strain doesn't look bad at all.
But most probiotics contain well over 5 different strains (and at least 5-10 billions CFU).
While in this product – there's only one (and just 2 billions CFU).
So in terms of the actual probiotics, Bio Complete 3 looks pretty bad.
Honestly, its formula is very disappointing at this (most important) chapter.
Despite its great initial impression – Bio Complete 3 is not as potent as it seems:
- great doses of pre/postbiotics
- really low dose of probiotics
- only one bacterial strain
So basically – as a prebiotic/postbiotic, this formula looks really promising.
But this supplement is designed as a probiotic.
And from this point of view, I consider it pretty weak.
So I wouldn't really recommend it, despite its good points.
#3 – Pills & Dosage (6 out of 10)
This product doesn't seem to look amazing from this point of view.
First of all – Bio Complete 3 is formulated as vegetable capsules.
Now, this kind of pills are usually pretty good – as they tend to be small and light.
But things looks pretty different in this supplement:
- capsules are a bit larger than most
- swallowing them isn't very easy
So they are definitely not the best when it comes to sizing.
Bio Complete 3 looks very bad here as well.
That's because it requires 4 pills every day – which is a huge dose, honestly:
- taking so many pills is quite uncomfortable
- they are also quite large in size (unlike their claims)
Now – it's recommended to space these pills out in 2 series.
In other words, you should take 2 in the morning and 2 in the evening.
Obviously, you can take them in a different approach, if you prefer.
But make sure not to take all 4 pills together – as you increase the risk of side effects.
#4 – Results (6 out of 10)
In order to see how a product works, I always check its user feedback.
And Bio Complete 3 has a lot of authentic reviews from previous customers.
So let's analyze them in detail.
Note: I only considered authentic reviews, not promotional ones.
1. Positive Opinions
First of all – this supplement is mostly sold on its official website.
It also claims not to be sold anywhere else, but Amazon does sell it:
- producer is the same brand (Gundry MD)
- formula is exactly the same
- pills are identical in shape/color/texture
- price is a little lower
For this reason – I'm pretty sure the product sold on Amazon is the original one.
Besides, it's sold on the official page of Gundry MD on Amazon.
If the seller was a scammer, I'm pretty sure it would have been rejected (Amazon is very strict with sellers).
Now, here's what you should know about its reviews:
- user opinions are almost entirely positive on the official website
- Amazon has lots of legit complaints
I typically avoid reviews from official websites, because they tend to be fake positive.
And honestly – this seems to be the case here.
That's why I will only consider its opinions from Amazon.
So here are the most common praises it received there:
- Some users say it really helped their digestion.
- Others claim their bloating improved a lot.
- A few others mention that it works really fast.
However, the negative part is a lot more interesting.
2. Negative Opinions
Surprisingly or not – most of Bio Complete 3's first page reviews are complaints:
- Many users claim it's a scam.
- Lots of people complain that it costs a lot but it doesn't work.
- Others even say their digestion actually worsened.
- Many others complain about side effects.
Now, Amazon has a lot of negative reviews on this product.
On the other hand – they are almost absent on its official page (which is quite obvious).
That's why I'm pretty sure these complaints are real.
If the product was actually so amazing – it would have far more praises even on Amazon.
Bio Complete 3 doesn't have an amazing user feedback:
- lots of complaints on Amazon
- only praises on its official website
In this case, there's no way I could believe the opinions from its official page.
So it may work for some – but it certainly doesn't work for many others.
That's why it's not a product I could recommend.
#5 – Side Effects (4 out of 10)
Bio Complete 3 seems to have some issues in terms of secondary reactions.
Again – all the complaints I found were on Amazon.
Its official page has absolutely no review about side effects, which is quite understandable.
Now, the side effects it seems to cause are pretty significant:
- severe bloating
Ironically, these are actually some symptoms it was supposed to treat.
Instead – it seems to cause them directly (or even worsen them).
Obviously, that doesn't happen in all cases.
But I did find a pretty high per cent of users complaining about issues of this type.
That's why I would think twice before purchasing it – it just doesn't seem very safe overall.
#6 – Price (4 out of 10)
For a probiotic, Bio Complete 3 is extremely expensive.
It's true that it does contain some trademarks (which tend to cost more than regular ingredients).
But even so – its formula is not as amazing as to be worth so much.
1. The Exact Price
Now – this supplement is available on both its official website and Amazon.
Again, if you ask me, the version from Amazon is the original one (it simply looks identical from all points of view).
However, the price on Amazon is a bit lower:
- A bottle costs around $57.
- That's a one month supply.
- There are no discounts for larger quantities.
Now, I personally believe the brand doesn't recommend purchasing the product from Amazon because of its lower price.
Instead, the price is higher on the official website:
- single bottle costs around $70
- there are some discounts for larger quantities
- but they are pretty minor
- in the best case, you can get it for about $59
So basically – the price is about the same as on Amazon (but only for the largest supply).
But honestly, this supplement is extremely expensive (even at its lowest price).
Again, it does contain some trademark ingredients.
But as a probiotic alone – it looks very disappointing.
If it cost under $30, it might have been a good option.
But in this actual case – there's no way I could recommend it for this price.
2. Competitors' Price
I will only compare Bio Complete 3 with my #1 recommended probiotic.
I'm talking about BiomeMD:
- Bio Complete 3 only contains one bacterial strain (in a low dose).
- BiomeMD contains 15 essential strains in some really high doses.
- It also combines prebiotics that feed the good bacteria.
- Bio Complete 3 costs $70/bottle normally.
- In the best case, you can get it for about $59.
- BiomeMD is cheaper at $49 as a standard price.
- In the best case, you can get it for about $28.
Now – between these 2 products, it's obvious that BiomeMD makes the better option.
As I said, it's my top recommended probiotic.
So obviously – it makes a great choice in terms of quality/price.
But compared to Bio Complete 3, it has a better formula but it also costs less.
That's why I strongly recommend going for it.
Bio Complete 3 is very expensive overall.
It's true that it's a pretty valuable product (from some points of view).
But that doesn't explain its huge price – especially since it's pretty weak as a probiotic alone.
So I couldn't really recommend it.
#7 – Final Conclusions
Here's how I would sum up my opinion on Bio Complete 3 (in 3 ideas).
1. Excellent Pre & Postbiotic
This supplement contains 3 types of ingredients, as I said.
And when it comes to its pre/postbiotic parts, it looks really good:
- based on unique ingredients
- its compounds are formulated as trademarks
So from this point of view – I would actually recommend it.
However, it's way too pricey for a pre/postbiotic – but in theory, it looks great.
2. Weak Probiotic
As for its probiotic part, Bio Complete 3 doesn't look as good:
- only one bacterial strain
- pretty low dose
- not versatile
Now – this supplement is formulated as a probiotic.
So you basically have to judge it from this point of view.
And to be honest, its probiotic formula is very disappointing.
3. Very Expensive
In terms of value, I doubt Bio Complete 3 is worth its current price.
It's one of the priciest probiotics I looked into, to be honest.
Now, it's definitely a legit product (and so its its brand).
But I personally would never pay so much on it, it's simply not worth it.
My Verdict – Worth Or Not?
Short answer: Not really.
It's definitely not a bad supplement – especially as a pre/postbiotic.
But as a probiotic, I would surely not recommend it:
- Only one bacterial strain (in a low dose).
- Requires 4 pills/day.
- Seems to worsen digestive symptoms in some people.
- Very expensive overall
Now – Bio Complete 3 is definitely far from a scam.
Its producer is a reputable brand and the supplement itself is very legit.
But again, I don't think it makes the wisest option overall.
Why spend so much money on it when you can get something stronger for a lower price?
So what alternative do I recommend instead?
A product called BiomeMD:
- excellent formula with 15 different strains
- has some really high doses
- also contains prebiotics for a stronger effect
- costs a lot less
If you ask me, BiomeMD is the best probiotic I know (in terms of quality/price).
That's why I consider it a much better option instead of Bio Complete 3.
