Frequently Asked Questions
Who are Bioli?
This should sound like an oscar-winning brand statement but it isn’t. We might look like just a regular supplement brand that aims to change the world, but we aren’t doing anything crazy. Just like many people, we want to enjoy our meals with friends and family without feeling discomfort.
And if you may feel down after many “failed” diets, it’s not your fault.
We are simply a group of dedicated people who have one goal – help you feel better and lighter than before.
But you might not find that easy, and we understand.
Behind our goal we have built a sophisticated manufacturing system that has gone through rigorous testing and certification. We are probably one of very few known brands in the market that offer 100% survivability of science-backed bacterial strains in your gut.*
Most importantly, we take transparency and accountability seriously. All the ingredients of your supplement are organically sourced, clinically tested, and clearly labeled on the packaging.
Bacillus subtilis broke the record of surviving for 6 years on a NASA satellite. And, we're not trying to make an impressive claim; we're simply stating that our strains have passed GMP certificate stability testing.
Otherwise, what’s the point of consuming a probiotic supplement if most strains die in stomach acid without ever reaching your gut?
Plus, you get the full digestive enzyme complex, so you could stop avoiding certain dishes on the menu, especially heavy foods. Feel the difference in your digestion because our formula does all the hard work for you. On top of that, you get a patented prebiotic blend with a natural postbiotic yeast, so you can start exploring new restaurants with confidence. The risk of food poisoning will drastically decrease, because postbiotics won’t let unwanted bacteria invade your body! Overall, feel the difference in your gut within hours, not in days.
Tired of throwing away plastic waste of supplements that expire too fast? Take it easy because our ingredients are stabilized in capsule form and the shelf life of each bottle is 2 years.
If you’re thinking what we’re thinking, you can take Bioli as your travel buddy! The bottle is compact and sturdy so you can throw it in your backpack and begin your taste journey.
Why should I choose Bioli over other brands?
About 99.8% probiotics are filled with tens of billions of CFU’s of weak probiotic strains. This is because their probiotic strains usually don’t survive when passing through the bile salt and stomach acid. That’s why these brands use “mega doses” to compensate for this loss so the fraction of those bacteria (if they make it out alive) would provide some benefits.
We took a different way.
Bioli uses Bacillus strains that have outer spore-like shells (the endospores) making them extremely durable against acids, temperature changes, light and so on.
But our supplement isn’t just a regular probiotic. It has a wide range of ingredients:
18 digestive enzymes – so you can easily digest foods you normally can’t
3 advanced spore-based probiotic strains – enjoy healthy gut with less dosage
4 PreforPro prebiotic bacteriophages – eliminate bad gut bacteria within hours
A natural postbiotic – friendly fungus with many health benefits
So, instead of having four separate supplements, we've combined all these ingredients into a single bottle, allowing you to save space and avoid worrying about which products work perfectly together.
Less waste – more taste.
Will Bioli work for me?
Many of our customers that experience the best results – including well-balanced gut bacteria, enhanced digestion, less bloating, stronger immune system, and even a slimmer belly – often order the 3 or 5 bottle packages of Bioli.
So, while a single bottle of Bioli can give you a lot of benefits, we recommend taking Bioli consistently for up to 3 months or longer so you can enjoy a balanced gut and steady weight loss.
There’s no added risk to you because you’re covered by our 100%, 14-Day money-back guarantee.
Remember, it takes time to achieve the best gut health possible and rebalance the gut ecosystem. Plus, everyone’s gut is different based on location, diet, genetics, access to proper nutrition, and daily exercise.
To be extra safe, we recommend consulting with your healthcare professional before consuming any dietary supplement.
How quickly should I expect Bioli to work?
Many of our customers reported to have experienced improvements in their gut health within just 2 weeks. And, some noticed changes in their digestion and bowel movements as early as 7 days. However, it's important to remember that individual results may vary depending on factors such as diet, exercise, and overall nutrition. Each gut microbiome may respond differently.
We believe that with consistent and recommended use of Bioli, you can begin to feel and see a noticeable change in your digestion, weight, and overall health within 2 weeks of purchase or we’ll return your money. No questions asked.
How to use Bioli properly?
This is how we recommend: Take 2 capsules daily preferably with meals or as directed by a healthcare professional.
Is Bioli safe to use?
Even though Bioli is considered safe to use in recommended amounts, we still recommend consulting your doctor before trying any health supplement.
We want to make it clear and simple:
- We put science and quality first
- Every capsule of Bioli is made in the USA in a GMP-certified facility.
- Our formula must also pass a series of third-party tests to ensure each bottle that leaves the facility contains live strains of probiotics.
- If the capsule doesn’t match our quality check, we utilize it.
So you can be safe knowing every dose you take is packed with real, live cultures with 6 billion CFUs (which is in a healthy and low-risk of side effects range) ready to go to work on your gut.
It’s always best to consult with a health professional before starting any health regimen. We recommend it.
Are there any side effects?
While digestive enzymes, prebiotics, probiotics, and postbiotics are generally well-tolerated. The possible side effects in rare cases could include gas, bloating, bubbling in the gut and abdominal pain. If you encounter any of these symptoms that could be caused by the product, consider reducing your intake and then gradually reintroducing it over time.
As with any supplement, it's important to consult your healthcare provider before starting probiotics.
What are bacteriophages?
Bacteriophages are harmless and the most abundant living organisms in nature. They’re found in ocean water, soil, humans, and fermented foods.
Interesting fact: There are 10x more phages in the human body than 100 trillion bacteria that live inside.
Are bacteriophages safe?
Yes! Bacteriophages or phages have a long history of safe use in food products. They have been used from food preservation to human therapy, with minimal side effects.
Bacteriophages are submicroscopic bundles of DNA that have a tough protein shell.
These specific phages are sworn enemies of many harmful bacteria strains and support the healthy environment in the colon. Because of these beneficial properties phages are classified as prebiotics.
We also recommend consulting with your healthcare professional before consuming any dietary supplement.
What are prebiotics?
Prebiotics are primarily considered a food source for beneficial gut bacteria. They are not bacteria themselves; instead, they consist of fibers and compounds that our bodies cannot digest. Some examples of prebiotic foods include oats, barley, onions, and garlic.
Bioli's prebiotic blend utilizes advanced PreforPro technology, which offers faster results and requires a lower dosage without causing discomfort. Unlike typical prebiotics, which often demand large doses and several days to become effective, our prebiotics have been shown to start working within hours, even with a small 15 mg dose.
Rest assured, our ingredients are not fiber- or starch-based, so they won't lead to digestive discomfort, bloating, or flatulence.
What are probiotics?
Probiotics are live microorganisms, often called "good" or "friendly" bacteria, that when consumed in adequate amounts, provide health benefits beyond basic nutrition.
Historically, sailors consumed fermented cabbage (sauerkraut) to prevent scurvy during long voyages, not realizing they were actually ingesting probiotics that also helped protect their gut health.
Here are some examples of probiotic rich foods: yogurt (non-flavored), kefir, sauerkraut, kimchi, miso.
What are soil-based organisms?
Spore-based probiotics, also known as soil-based probiotics, are derived from soil bacteria and consist of endospores. These endospores provide a protective layer for the probiotic strains, making them highly resilient to stomach acid, bile salt, and pancreatic acid. Unlike most other probiotic products available, this evolution enables spore-based probiotics to withstand the digestive process, potentially leading to improved delivery of probiotics to the intestines.
These microorganisms help:
- Promote the growth of good bacteria
- Balance the gut by increasing microbial diversity
- Kill bad gut bacteria and produce metabolites that trigger the regrowth of good bacteria
- Treat antibiotic-associated diarrhea and traveler's diarrhea
- Decrease leaky gut symptoms by repairing gut lining
- Reduce IBS symptoms
Does Bioli contain any allergens?
Bioli may have traces of milk, soy, and wheat which usually comes from a fermentation process.
Before trying any supplement, please consult with your healthcare specialist.
What ingredients Bioli is using in their capsules?

Who should NOT use Bioli?
Bioli usually is generally safe to use in recommended dosage for most healthy adults. But, we highly recommend consulting with a health professional, especially if you use:
Blood-thinning medications: Enzymes like bromelain and papain have natural blood-thinning properties. They could potentially enhance the effects of blood-thinning medications (like warfarin), increasing the risk of bleeding.
Diabetes Medications: Since digestive enzymes aid in the breakdown and absorption of sugars and carbohydrates, they might affect blood sugar levels. This could interact with diabetes medications, necessitating adjustments in dosages.
Immunosuppressants: Probiotics may stimulate the immune system, which could be counterproductive for people taking immunosuppressive drugs.
Because of the resilient nature of our soil-based probiotic, it may be difficult to flush them from your system.
Also, if you are pregnant or nursing, or suffer from chronic or serious conditions, please contact your healthcare professional first.
What other health benefits does Bioli haveto offer?
Bioli helps 5 different organ systems:
- Integumentary – healthier skin, nails & hair
- Digestive – improved digestion, nutrient absorption & appetite control
- Nervous – improved mood control & reduced emotional eating
- Cardiovascular – reduced risk of heart disease & improved blood sugar control
Lymphatic – strengthened immune function & resistance to bacterial infections
Can I use Bioli with antibiotics?
Yes, you can. Bioli has 3 clinically proven Bacillus strains that are resistant to antibiotic effects. These beneficial bacteria have been shown to strive under harsh conditions and fight H. Pylori, bloating, rotavirus, IBS, and diarrhea.
To be safe, we highly recommend consulting with your healthcare professional before consuming any dietary supplement.
Is Bioli suitable for SIBO (bacterial overgrowth)?
Yes, that's why our special formula includes 3 clinically proven Bacillus strains, 4 patented PrefoPro bacteriophages, and a natural postbiotic S. cerevisiae. These components are designed to target and eliminate specific harmful bacteria that cause Small Intestinal Bacterial Overgrowth, reducing gut discomfort and associated symptoms.
Also, we highly recommend consulting with your healthcare professional before consuming any dietary supplement.
Is Bioli suitable for candida?
Some research suggests that certain strains, such as Bacillus subtilis and Bacillus coagulans, have antifungal properties that may be effective against Candida albicans.*
Additionally, soil based probiotics are known to support the immune system, which plays a crucial role in battling Candida infections.*
Some studies show that taking live Saccharomyces cerevisiae (a type of yeast used as postbiotic) just once can help get rid of Candida just as well as fluconazole, a drug often used to treat fungal infections.
However, we highly recommend consulting with your healthcare professional before consuming any dietary supplement.Galbūt “Consult your health care provider/doctor/physician before taking dietary supplements to treat a health/medical condition”
Is Bioli suitable for IBS?
Yes, that's why our special formula includes 3 clinically proven Bacillus strains, 4 patented PrefoPro bacteriophages, and a natural postbiotic Saccharomyces cerevisiae. These components work together to eliminate specific harmful bacteria, typically including up to 40% of Brachyspira bacteria, thereby reducing gut discomfort and associated symptoms.
Multiple scientific studies and numerous products, existing on the market, have proved effectiveness of soil-based probiotics, prebiotics with PreforPro bacteriophages and dry yeast fermentate (S. cerevisiae) in managing IBS.
A recent double-blind placebo trial examined 456 individuals for 8 weeks. One group took S. cerevisiae postbiotic and the other took a placebo. The results indicated that this postbiotic helped relieve IBS symptoms including abdominal pain and constipation.
For better safety, we recommend consulting with your healthcare professional before consuming any dietary supplement.
Is Bioli suitable for GERD/heartburn?
Yes. Our blend of 18 natural enzymes and 4 advanced PreforPro probiotics is designed to help improve digestion. Postbiotics and PreforPro can help fight H. Pylori – one of the main bacteria that cause peptic ulcer/GERD.
Some ingredients in digestive enzyme supplements, like protease, could potentially help digest proteins more thoroughly, which might reduce the occurrence of reflux. However, certain enzymes, particularly those derived from fruits like papain and bromelain, might actually exacerbate symptoms in some individuals due to their activity in a wide pH range, including the acidic environment of the stomach.
That’s why we highly recommend consulting with your healthcare professional before consuming any dietary supplement.
Is Bioli suitable for recurring gastritis?
Yes. Our blend of 18 natural enzymes and 4 advanced PreforPro probiotics is designed to help improve digestion. The enzyme complex helps breakdown of foods and reduces digestive workload, probiotics may help balance stomach flora which absorbs more nutrients and gets rid of excess toxins.
Postbiotics and PreforPro can help fight Helicobacter pylori – one of the most common bacteria that can cause gastritis.*
However, we highly recommend consulting with your healthcare professional before consuming any dietary supplement.
Is Bioli suitable for ulcerative colitis or Crohn's disease?
Yes. Probiotics, like the Bacillus strains and postbiotics like Saccharomyces cerevisiae have been shown in some clinical studies to help maintain remission in ulcerative colitis and prevent relapses of Crohn's disease due to their role in balancing gut flora and potentially reducing inflammation. Enzymes may aid digestion and reduce digestive workload, possibly beneficial for those with such conditions.
However, it's important to be cautious because everyone's situation is different. That’s why we recommend consulting with your healthcare professional before consuming any dietary supplement.
What if I don’t feel any effects?
Generally, most people who consume Bioli report feeling the effects within several hours. For the best results, we recommend taking it for at least 3 to 5 months so you can also notice significant weight loss.
However, if you don't feel any effects within the first 14 days, don't worry – we'll refund 100% of your money, no questions asked. We all have unique microbes in our gut, which is why results may vary from person to person. But that shouldn't discourage you from taking action and improving your quality of life.
So, before trying any supplement or medical practice we always recommend consulting with your healthcare professional.
What if I subscribe and change my mind?

Why am I not losing weight yet?
Most people report their waist size dropping down in a matter of weeks, but their weight could still be nearly the same.
But that’s temporary because our probiotics and prebiotics start overpowering the bad bacteria that cause your body to store fat and crave sugar.
The body has to adapt to changes in the gut so it can burn that excess fat for energy over time. That’s why we recommend taking the supplement for at least 3 to 5 months to see a noticeable change in weight.
If you don’t notice any changes in your weight after this time, this could mean that you may need to lower your calorie intake or switch to more quality foods, mostly greens. Alternatively, you may want to consult with your dietitian to see how you could improve your diet.
If you want to be more certain about the effectiveness of Bioli or any other supplement, we highly recommend consulting with your professional healthcare provider.
