Who Is PrebioThrive For? 

Prebiothrive is for anyone who is looking to support their digestive system. This product supports the digestive tract bacteria in addition to other so many benefits that anyone would love and get value from.

PrebioThrive is designed to fuel your healthy gut flora and improve your digestive inflammation and is marketed as a powerful supplement for those who suffer from inflammatory bowel disease, constipation or irritable bowel syndrome. It can also help in losing weight.

Let us take a closer look at the ingredient list and the benefits.

PrebioThrive Key Ingredients

All the PrebioThrive ingredients are organic and 100% natural. The ingredient list is pretty short and concise. It doesn’t contain any additives. Let’s look at each ingredient and what it does.

Prebiothrive ingredient list

The PrebioThrive ingredients list includes five fiber-rich prebiotics that are said to help improve digestion, eliminate digestive disorders and promote good bacteria growth.

Unfortunately, the specific quantities of these ingredients in each serving are not included. However, lets dissect each of these.

Acacia gum

Acacia gum is a water-soluble fiber from the sap of an acacia tree. It is used in a variety of products, from supplements to lozenges and ice cream. Research has shown it to be better at increasing bifidobacteria and lactobacilli.

Acacia gum dissolves in water and forms a gel, it is useful in reducing gut inflammation, suppressing appetite, and keeping cholesterol levels under control.

When used as a supplement at a dose of 10 g/day for about 4 weeks, it promotes the growth of healthy bacteria and can also help with irritable bowel syndrome. 

Agave inulin

PrebioThrive also features agave inulin which is extracted from the blue agave plant. Inulin contains 100% of the dietary fiber found in agave and many plant species. The agave inulin is a great dietary fiber that not only helps improve intestinal health but also the functioning of the immune system. Additionally, it helps reduce appetite by promoting a feeling of satiety, or fullness.

There are a couple of studies that show how good inulin is for the body. One such study was conducted on 44 subjects with prediabetes. The subjects were given inulin supplements for a period of 18 weeks and by the end of this period the group had lost an average of 5% body weight. 

Therefore, agave inulin in the Gundry MD Prebiothrive will not only lead to good bacteria growth but also possible weight loss.

Research has also proven its ability as a good prebiotic which specifically grows fecal Actinobacteria and Bifidobacterium while starving Desulfovibrio gut bacteria by up to 40%. Eventually, this results in a particularly balanced gut microbiome.

Inulin despite being sweet, also helps improve insulin resistance as it has a low glycemic index making it healthy for people at risk of high blood sugar cravings.


Flaxseed is a great source of fiber and antioxidants. Fiber is generally indigestible and water-soluble.

Flaxseed also contains protein, lignans, and omega-3 fatty acids called alpha-linolenic acid or ALA, which makes it an overall good health ingredient supplement.

ALA not only reduces inflammation but has also been shown to reduce the likelihood of many different types of heart problems. In addition, flax seed is known to lower cholesterol levels, and contain cancer-fighting and antioxidant properties which can particularly be of help in your weight loss journey.

Guar gum

Guar Gum is highly water-soluble fiber and is extracted from guar beans. It acts as a bulk laxative. Studies show that it stimulates the boom in healthy gut bacteria, helps promote regular bowel movements and treat IBS (irritable bowel syndrome).

Guar gum helps increase feelings of fullness which play a role in reducing the absorption of cholesterol by the body according to one study.

However, the FDA has banned the use of guar gum in weight loss products due to some complement manufacturers using it in greater than recommended dosages thus resulting in significant physical fitness problems in the early 1990s.


Abbreviated as GOS, Galacto-oligosaccharides are a member of the low glycemic index family of oligosaccharides that are naturally found in mammalian milk. These Galacto-oligosaccharides prebiotic are made up of sugars from dairy products and plants like beans and root vegetables which can improve mineral absorption and support your immune system.

It is used regularly as a sweetener or to treat a number of bowel conditions such as constipation, IBS, and ulcerative colitis.

GOS can help soften stools, increase the frequency of bowel movements, and make it easier passing of solid waste according to various studies.

PrebioThrive Benefits

The most significant benefit among many others of this performance lab prebiotic is that it protects and supports healthy probiotics in the gut.


PrebioThrive is designed to support a healthy gut microbiome. Some of the key benefits include:

Improved digestion

By eating better, you have more energy, and sleep more soundly, you also see an improvement in your mood. In other words, you will not be starving anymore, feeling heavy and bloated, and you will see how this drinkable formula helps keep your mind balanced too.

Weight management

While taking prebiotics does not lead to weight loss on its own, these can be of aid when you want to improve you want to manage your weight.

The fiber-dense ingredients in this supplement can also promote the production of short-chain fatty acids. These are a result of the good bacteria fermenting fiber, and they can reduce the risk for heart disease, type 2 diabetes, and inflammation. Furthermore, you can lose weight thanks to these fatty acids in your gut.

Improved overall health

Much of what we do in our lives revolve around eating and how we feel about food. It is evident that if we feel good about ourselves and our digestion is better, then we generally see improvements in all aspects of our health.

Does PrebioThrive Work?

At this point you might be wondering does this supplement really work with regards to it ingredients. Does it do what it set out to do. In the same breath we will look at some of the customer prebiothrive reviews.

Now, we get to try and answer the million-dollar question: does PrebioThrive deliver?

An article in Today’s Dietician magazine explains that promoting good gut bacteria could help to reduce the number and effect of gut pathogens.

“The most well-studied prebiotics are fructooligosaccharide (FOS), inulin (a type of FOS), and galactooligosaccharides. Once fermented, they’re associated with an increase in short-chain fatty acids (SCFA), especially butyrate, acetate, and propionate. These SCFAs help improve laxation, may decrease cancer risks, and provide fuel for colonocytes, helping to maintain a healthier gut barrier to pathogens and other substances that may cause illness”

According to a recent study by Sanders and colleagues, ingestion of prebiotic formulations can improve calcium absorption, and reduce duration, incidence, and symptoms of traveler’s diarrhea; alleviate IBS symptoms; prevent specific allergies; reduce energy intake and markers of insulin resistance; improve body weight management and increase satiety and decrease appetite. If you felt that your diet could use improvement in the sense that you weren’t taking enough plant fiber, you could supplement it.

This product gets high marks for efficacy when used in conjunction with probiotic supplements according to PrebioThrive customers. Some customers had this to say;

“This is the only thing I’ve found to keep me regular; I was having such a hard time not being able to go to the bathroom more than 2-3 times a week and when I did it was hard and painful until I started PrebioThrive. I couldn’t do the mixture by itself with water so my favourite way to make it is in the morning I blend banana, water or almond milk, peanut butter, cinnamon and cocoa powder with some ice and PrebioThrive. It’s delicious and when I’m consistently using it I go to bathroom immediately after I drink my shake or sometimes before I’m even done. Always lept until 12-1 in the afternoon unless I had to be up. Now I’m up at 9 everyday with no problems and lots of energy! Thank you, Dr. Gundry!”

I have used Gundry MD products before, and they always do a good job. I feel like this prebiotic blend is still a good choice because of the benefits I have seen so far.

I would request a refund if this was at all possible! This product was a total fizzle; the taste, texture and results were worse than anything I have ever experienced in any product touting itself as a beneficial health formula. It was an ordeal to get it to mix in water, and to swallow it was nauseating. It made me crampy and made my abdomen ache all day. Please let me know what I can do to be compensated for this $99. + cost.

PrebioThrive on Gundry MD has a 4.8/5-star rating based on 590 reviews, a 3.9/5 stars rating on Amazon from 632 ratings, a 4.3/5 stars rating on Trustpilot from over 5,428 reviews and 4.33/5 stars rating on Better Business Bureau based on 3,188 customer reviews.

Potential Side Effects

According to Gundry MD, PrebioThrive is 100% safe and of high quality for anyone who is not getting enough prebiotics in their diet. However, some customers disagree as above discussed, which leads to this section. Here are some of the side effects cited in some online reviews of prebiothrive;

  • Mild Gas

  • Bloating

  • Stomach Cramps

  • Fatigue

  • Constipation

It is important to note that the supplement contains milk which could be an allergen to some, so if you’re allergic to dairy you may need to stay away from PrebioThrive.

In addition, many of the prebiotics in FODMAP are excessive and consequently, some people may be sensitive to them, especially those with IBS, and other different stomach discomforts in the event that they eat junk food high in FODMAP. FODMAPs are fibers that ferment in the colon, similar to prebiotics.

These side effects are most evident when you use too much of the product. It is advisable that you reduce the dose when you start experiencing these side effects. 

Researchers have concluded that prebiotics can be an effective alternative to nutritional restriction in a few people.

One concern with PrebioThrive is that it’s not clear how much of each prebiotic is contained in a serving, so it’s hard to know an appropriate dosage for those with sensitivity to one of the ingredients in certain amounts.

Everybody will have a different reaction to different prebiotics. Some may experience side effects from one or more of the ingredients in PrebioThrive, like gas, bloating, abdominal cramping, nausea or loose stools.

PrebioThrive Recommended Dosage

Gundry MD website recommends a dosage of one scoop of PrebioThrive (10 grams) in eight fluid ounces of water every morning.

This dosage will deliver 7g of organic fiber and consuming this dose supports regularity and will give you the most benefits.

PrebioThrive Powder Scoop

With the risk of repetition, remember, however, the supplement is more effective when combined with a probiotic supplement.

Is PrebioThrive Worth It?

PrebioThrive contains five different prebiotic ingredients that Dr. Gundry claims will improve digestion and bowel health by promoting a healthy gut flora.

Separately, the product’s ingredients are safe for most people and have shown to better the health of the gut in various studies however, there’s been no research done on PrebioThrive itself or the combination of ingredients it contains.

Healthy digestion and feeling your best require a commitment to a lot of things such as eating a nutrient-rich whole food diet to maintain a healthy digestive system. Regular movement, proper stress management, and keeping a healthy weight are also very important. 

If your lifestyle does not allow you to be on top of these, doing your research and choosing a clinically proven system may be a suitable approach.

Based on this PrebioThrive review, I’m convinced that it is a potent and effective prebiotic formula with benefits supported by several clinical studies.

In general, prebiotic supplementation may be useful for some people, but you can just as well get a healthy range of prebiotics in your diet.

Eating a variety of prebiotic-rich food such as root vegetables (onions, garlic), fruits (apples, bananas), greens, lentils, nuts and whole grains help promote a healthy and diverse gut microbiome.

Is it better to take prebiotics or probiotics?

To begin, you should not think of prebiotics and probiotics as alternatives to each other.

The two supplements work together to support good bacteria in your gut. Probiotic supplements contain actual healthy good gut bacteria. On the other hand, prebiotic supplements help your body better absorb these bacteria.

Generally speaking, you can think of probiotics as a gut health booster and prebiotics as a multiplier that makes probiotics more effective.

For the most part, when you are only taking one of the two supplements, probiotics are likely to be more effective. That said, you will get the best results by combining the two.

How long does it take for PrebioThrive to work?

If you are trying to improve your gut health, then do not expect to see results overnight. Ultimately, rebalancing your gut bacteria can take time.

Furthermore, you should combine your prebiotic supplementation with a healthy diet and a probiotic to make sure you are taking a holistic approach.

All things considered, we recommend sticking with your regimen for at least 60 days to get the best results.

To prevent any side effects, try starting with a small dose and work up to the recommended one. Some downsides include;

Proprietary blend. We can’t tell how much of what is in this supplement.

Poor customer feedback. Overwhelming poor feedback would make anyone hesitate buying this.

Too good to be true commercial. Customers say the marketing team did a great job at making them buy a product that doesn’t work.


In conclusion, living healthy involves a number of things including exercising, making smart meal choices and keeping a healthy weight. This could be difficult and that’s why it’s important to choose a clinically proven system.

Now we have taken a look at all the ingredients of PrebioThrive and it’s definitely suitable for the health of your digestive system. In fact, its benefits are also supported by clinical studies.

Overall, the ingredients are simple and effective. The combination of acacia gum, agave inulin, flax seed, guar gum, and galacto- oligosaccharides make this type of prebiotic fiber supplement superior.

We consider PrebioThrive to be a well-researched formula of prebiotics, transparent in their origins and applications.

In addition, the company is very transparent in its ownership, marketing, labeling, and packaging and even offers a 90-day money-back guarantee. These products also undergo testing with an independent third-party facility.

PrebioThrive has rightfully received excellent grades for efficacy, supported by many favorable customer reviews on the company website and others.

All in all, there are some reservations about support for this product. The product appears to have some side effects according to some of the reviews on other platforms like amazon and Trustpilot. This is in contrast to the main website where prebiothrive is said to have no side effects. It is thus actually difficult to determine if it is a scam or not.

The Prebiothrive reviews on their site could be fabricated or not besides reaction differs from person to person to different products.

That said, you should carefully do your research before using Prebiothrive. The best thing to do is talk to your physician before using any dietary supplements. It is prudent to consult with a medical professional before using this supplement to avoid any discomforts.
