If you’re here, you’ve probably heard the buzz and want to know which products are worth your time. Bioma Probiotics stands out from the pack by promising to balance your gut and, in turn, support weight loss—who wouldn’t want that?

But does it really work? In this Bioma Probiotics review, I’ll break down the science behind its ingredients, explore its potential benefits, and help you decide if it’s worth the investment—especially if weight loss is your goal.

Bioma Probiotics overview

Bioma Probiotics is a dietary supplement designed to support gut health. Each two-capsule daily serving promises to rebalance your gut and boost your ability to lose weight. Let’s look at what’s inside and how it works.

Bioma ingredients and gut health probiotics benefits

Bioma labels its product as a probiotic, but it’s technically a synbiotic. Synbiotic supplements offer more complete gut health support by combining probiotics with

prebiotics

and postbiotics.

Here’s how these components work:

• 
  Probiotics
  
  are good bacteria that live in your gut, supporting digestion, immunity, and overall health. (
  
  1
  
  )
• 
  Prebiotics
  
  (mostly fibers) feed these bacteria, helping them grow and stay active. (
  
  2
  
  )
• 
  Postbiotics
  
  are substances produced by probiotics that aid nutrient absorption and digestive tract health. (
  
  3
  
  )

We like Bioma’s formula because it contains three well-studied probiotic strains from the

Bifidobacterium

family:

B. breve, B. longum, and B. lactis

.

Bifidobacterium

are major players in good gut health, and low levels are linked to digestive issues like irritable bowel syndrome (IBS). (

4

)

Supplementing with these strains may help restore good bacteria levels and help improve your health by boosting immunity, reducing inflammation, and supporting good digestion. (

5

) If you’re struggling with digestive discomfort,

B. lactis

may specifically help with relieving bloating, gas, and constipation. (

6

)

Each two-capsule serving is said to provide 9 billion CFUs (colony-forming units), which indicates the number of live, active bacteria. (

1

) While this is a strong dose, Bioma’s proprietary blend doesn’t specify how much of each strain it contains. Without this information, we can’t say how effective the blend is since we can’t compare it to doses of strains used in clinical studies.

Bioma’s prebiotic ingredient is xylooligosaccharides (XOS), a sugar molecule found in fruits and vegetables. Bioma sources it from corn cob. Since your body can’t digest it, XOS travels to your lower intestine, where it feeds good bacteria—especially

Bifidobacterium

strains. (

7

) Research suggests it may also help manage blood sugar and cholesterol levels, which is important for people who are trying to lose weight or just stay healthy in general. (

8

)

Finally, Bioma includes tributyrin, a postbiotic that delivers short-chain fatty acids (SCFAs) to your gut. SCFAs may help strengthen the gut lining, protecting against harmful substances, like viruses, and improving symptoms like diarrhea and bloating. (

9

)

While animal studies support tributyrin’s benefits, human research is still new. One small study found that a 300 mg dose boosted SCFA levels in 21 days, but Bioma’s formula only provides 90 mg per serving, so its impact may be limited. (

10

) Still, it’s a promising ingredient for gut health.

Bioma offers a well-rounded formula with research-backed ingredients that may work better together than alone. However, the lack of transparency around specific strain doses makes it hard to fully judge its effectiveness.

Does Bioma Probiotics work for weight loss?

Bioma claims its gut health-boosting benefits help with weight loss, and they may be right. Some research suggests probiotics, like those in Bioma, can influence weight by affecting how your body absorbs nutrients, regulates hunger and metabolism-related hormones, and stabilizes glucose, which helps with possible hunger fluctuations. (

,

)

People with more diverse gut bacteria tend to have

better weight management

, while those with less diversity often store more energy and have less hunger control. (

11

,

12

) Early studies show that supplementing with

Bifidobacterium

strains, like those found in Bioma, may help improve gut diversity and aid weight loss. (

11

,

13

)

That said, probiotics aren’t a magic fix. These studies also showed a reduction in the intake of calories and/or an increase in physical activity among participants. It’s unlikely you’ll see weight loss benefits from taking probiotics alone. (

14

) Plus, Bioma’s proprietary blend makes it hard to know if its formulation matches the effective doses seen in research. But if you’re already making healthy lifestyle changes, probiotics could be a helpful way to support your efforts.

How to take Bioma Probiotics

Bioma suggests taking two capsules daily with a full glass of water before breakfast. The capsules are vegan, gluten-free, and non-GMO, though they’re made in a facility that handles allergens like shellfish, fish, nuts, and soy.

We’re happy that Bioma uses delayed-release capsules to protect the probiotics from stomach acid, helping more bacteria reach your lower gut where they’re most effective. Further, there are prebiotics which help the survival process alone, even if you are not going to consume food close to intake.

Each bottle holds 60 capsules, enough for one month. However, it’s unclear if the 9 billion CFUs listed reflects the live bacteria count at the time of manufacture or expiration. Since probiotics must be alive to work, we usually recommend products that guarantee CFUs through the expiration date for full benefits.

Nonetheless, Bioma takes extra steps to protect its probiotics. The strains are freeze-dried, making them more resistant to heat and storage conditions, so no refrigeration is needed, which is a nice convenience in your daily routine. (

15

) The capsules also come in a dark glass bottle to block UV light that could damage the bacteria.

Testing and certifications

We confirmed with Bioma that its probiotic supplement is third-party tested. While the FDA requires supplement companies to be honest about their ingredients, they don’t check formulations for accuracy before products are sold. (

16

) Third-party testing means an independent lab ensures a product’s ingredients and dosages match the brand’s promises. The best supplement products provide this transparency.

Bioma is also made in an FDA-approved, GMP-certified facility, which ensures it meets high safety and manufacturing standards.

One issue is that Bioma’s official website claims to offer probiotics tailored to your health needs, but this is a bit misleading. You take a quiz, and based on your answers, they recommend one of their three standard supplements—not a unique formula.

Bioma Probiotics side effects

Probiotics and prebiotics, like those in Bioma, are generally low-risk, but individual responses can vary. Some people may experience worsened gastrointestinal symptoms, like gas or bloating. (

1

)  Prebiotics, as fermentable fibers, can also cause abdominal discomfort.

If you have a weakened immune system, avoid probiotics, as they may increase your risk of infection. Additionally, probiotics can sometimes interfere with certain medications by affecting how they’re metabolized. (

17

,

18

)

There’s little evidence of severe side effects from tributyrin, but research on it is still limited.

As with any supplement, it’s best to consult your doctor before starting. If side effects occur, work with your doctor to adjust your plan.

Cost and value

Bioma Probiotics are more expensive than average. A one-time purchase of a 30-day supply costs $79.99 or $2.67 per dose, much more than similar supplements. However, they often run sales and offer bulk discounts and subscriptions to help lower prices.

The return policy isn’t the most flexible. You have 14 days from your order date to request a return, which doesn’t give you much time to try the product. Plus, you’ll need to pay a $9 return shipping fee.

We do like that you get two free ebooks with your order on gut repair and

anti-inflammatory diet

. These extras show that Bioma understands the importance of a holistic approach to gut health and adds more value to the overall package.

What customers are saying

Over 1,000 Amazon customers rated Bioma Probiotic supplement a 3.7 out of 5 stars—around 50% of these customers like the healthy gut results they’re seeing from this product.

Another customer, Sally, describes it as “surprisingly great,” saying she was “pleasantly surprised by this brand of probiotic. My digestion is noticeably better, my skin looks better, and I have lost weight (maybe 9 lbs. in two months of using it). The most noticeable effect for me is the level of detachment from food choices that I now have. I can consider what makes the most sense to eat and fuel my day rather than spinning headlong after an ill-advised craving.”

However, many customers find it overpriced for what it contains. A customer named Paige writes, “These work just as well as my regular probiotic supplement, which is way cheaper than these. These are 7x more expensive than my regular brand…I will not be purchasing them in the future.”

Several other customers feel this product doesn’t live up to its hype, with claims about weight loss and sugar cravings feeling like a scam, but everyone responds differently to supplements. Others report an increase in symptoms like bloating, gas, and diarrhea, which can be a side effect of starting a new probiotic formula. This is a good reminder that it’s important to discuss this product with your doctor.

Expert opinion

We consulted with Victoria Burgess, Ph.D., CSCS, CISSN, a certified sports nutritionist, for her insight on this probiotic supplement:

“This probiotic boosts a good amount of CFUs, which help the survival rate through absorption, allowing for the most beneficial bacteria to enter the intestine. The fact that it is a synbiotic, which includes pre- and postbiotics as well, makes it a great all-around product. Pre- and postbiotics can be especially helpful for those who might not consume fibrous foods, to help with the ‘feeding’ and survival and health of the probiotics.”
