In our prebiotic supplements reviews, we explain how important it is to consume enough fiber throughout the day. Suppose you want to up your insoluble and soluble fiber intake without spending a ton on groceries. In that case, Garden of Life’s Dr. Formulated Fiber dietary supplement is just what you need.

Because of its outstanding quality and countless best prebiotic supplement reviews, we believe that this is the best organic supplement on the market without artificial additives and unnecessary sugar. 

You get 1g of insoluble fiber and 4g of soluble fiber, or 5g of prebiotic fiber in total, in each serving. This product derives its prebiotic fiber from cranberry, baobab fruit, orange peel, and organic acacia fiber, which is just one of the reasons you’re likely to find it in just about every top-10 prebiotics list out there.

Interestingly, a study from 2013 shows that acacia fiber creates more healthy bacteria than other similar fibers, without gas or bloating. Since it does not contain any psyllium, you will not experience a gritty texture when mixing it with your beverage or food of choice.

Overall, this is the best prebiotic supplement for people with different sensitivities, such as consumers with soy, dairy, and gluten allergies.

Suggested use — One tablespoon mixed with a beverage.

PROS:

Prebiotin Prebiotic Fiber Review

OVERALL RATING 9.7
  • Editor’s choice: Best prebiotic supplement for weight loss

  • Doses per container: 60
  • Prebiotic fiber content: 4g
  • Shipping: Free shipping on orders over $49.00

Inulin can potentially control diabetes, improve digestion, and aid in natural weight loss. With this taken into consideration, we believe that Prebiotin is one of the best prebiotics for weight loss as it has 4,000mg of oligofructose-enriched inulin derived from chicory root.

Unlike regular inulin, oligofructose-enriched inulin can nourish healthy bacteria’s growth in the intestines. Also, OEI aids in magnesium and calcium absorption.

Besides weight loss, we recommend this product for:

  • increased bone density
  • enhanced immunity 
  • appetite control
  • leaky gut
  • increased absorption of calcium
  • addressing constipation

Since it is cholesterol-, fat-, and sodium-free, it is suitable for people with different dietary restrictions. Moreover, the prebiotic products from Prebiotin are gluten-free and vegetarian-approved.

Even though this full-spectrum prebiotic powder is unflavored, customers claim that it has a slight vanilla-like taste. What’s more, it is easily mixed into any beverage or sprinkled over food.

Disclaimer: Since Prebiotin packages these prebiotic supplements for weight loss in the facilities where soy and nut products are processed, they may be unsuitable for people with specific allergies. 

Suggested use — Start with 1/2 scoop daily for the first week, and increase slowly to one level scoop; repeat two (or more) times per day.

PROS:
  • Full-spectrum prebiotic for ultimate gut health
  • Suitable for the leaky gut syndrome
  • Gluten-free
CONS:
  • Has a slight vanilla flavor despite being marketed as unflavored

If you are looking for the cheapest, good prebiotic fiber supplement, then KOS Organic Inulin Powder with 100% pure inulin should be on your radar. This supplement offers 3g of pure fiber for digestive health support, stronger bones, and appetite control that is almost on par with the best appetite suppressants on the market.

As mentioned before in our prebiotics supplements reviews, the soluble fiber-rich inulin is an entirely natural, flavor-free prebiotic suitable for people with allergies or specific dietary preferences (such as vegans). 

Besides being USDA organic, good prebiotics by KOS are free of GMO, dairy, soy, and gluten. They are also incredibly gentle on the stomach, so you do not have to worry about uncomfortable bloating or cramping.

According to experts, the daily recommended amount for inulin prebiotics is between 4g and 20g. So, keep in mind that you may experience adverse effects with the KOS Organic Inulin Powder if you exceed this dose.

Best of all, with each purchase you make at KOS, you also support the Feeding America project. That means you help the company provide a meal to a person in need when buying a KOS product. We love brands that give back, so we believe that KOS deserves a place in our best prebiotic supplement reviews.

Suggested use — One scoop daily mixed with a beverage.

HealthPlus MAX Prebiotic Formula Review

OVERALL RATING 9.6
  • Editor’s choice: Best natural prebiotic supplement with added beneficial ingredients
  • Form: Capsules
  • Doses per container: 60
  • Prebiotic fiber content: 1,005mg proprietary prebiotic blend; 2g of prebiotics
  • Shipping: Standard shipping in the US
  • Price and discounts: $22.99, frequent holiday discounts

Are you looking for a more affordable alternative to RenewLife Daily Balance? Fortunately, MAX Prebiotic Formula with prebiotics and probiotics is suitable for budget buyers as you get 60 servings in each container.

This best-rated prebiotic and probiotic supplement offers the following:

  • a proprietary prebiotic blend (with inulin, burdock root, fructooligosaccharides, and arabinogalactan bark)
  • a proprietary probiotic blend 
  • proprietary digestive support (with hemicellulase, beta-glucanase, and slippery elm bark)

Thanks to the combination of these ingredients, this formula is beneficial for both digestive system health and immunity support.

Besides being an excellent probiotic, burdock root is also a potent antioxidant with blood sugar-decreasing and anti-inflammatory properties. Other ingredients, such as slippery elm bark, are used to remedy diarrhea, hemorrhoids, irritable bowel syndrome, constipation, and GI inflammation. 

Overall, this is without a trace of doubt one of the best prebiotic supplement products for those looking for something that will promote the growth of beneficial bacteria in the intestines.

On the downside, the amount of prebiotics in this formula is lower than in other comparable supplements on the market. Although you only get 2g of daily prebiotics, the overall value to price ratio and the ingredients’ quality make it worth checking out.

Suggested use — Three capsules twice a day.

Buyer's Guide on How to Find the Best Prebiotics on the Market

As promised, here is a detailed and easy-to-follow buyer’s guide to help you find the best prebiotic supplement for your specific needs. We will tell you what to look out for, what to avoid, and why we recommend these supplements.

But first, what is a prebiotic supplement? Well, indigestible dietary fibers are called prebiotics. Their primary role is to increase the growth of helpful microorganisms in the colon and intestines.

The top three prebiotic compounds are galactooligosaccharides, fructooligosaccharides, and inulin. Although these were not always classified as fibers, researchers revealed that they act similar to other fiber types.

So, how are prebiotic products different from probiotic supplements? Prebiotics support the gut’s existing bacteria by transmitting nutrients to the most beneficial strains. In comparison, probiotics provide foreign kinds of bacteria to re-balance a person’s microbiome.

Who Can Benefit From Prebiotic Pills and Powders?

Many falsely believe that prebiotics are only for individuals with digestive complications. The truth is that everyone can benefit from prebiotics. So, whether you want to increase the concentration of beneficial digestive enzymes, fight irritable bowel syndrome, ward off anxiety, boost brain function, or lose weight, a high-quality prebiotic can come in handy. Moreover, people who do not consume enough fiber may benefit from whole food prebiotics or a prebiotic supplement. According to experts, the recommended daily amount of fiber for women is 25g, whereas men should aim for 38g.

Potential Health Benefits of Prebiotic Supplements

Here are the principal reasons many healthcare professionals recommend eating more prebiotic-rich foods and consuming high-quality prebiotic supplements:

  • lowering cholesterol
  • immune system stimulation
  • fighting off illnesses
  • colorectal cancer prevention
  • inflammatory bowel disease (IBS) prevention
  • constipation relief
  • improved digestion
  • obesity prevention
  • enhanced absorption of some nutrients (such as magnesium and calcium)
  • help with weight loss
  • boosted energy levels and warded off depression/anxiety

Are Prebiotic Capsules, Pills, and Powders Safe?

Generally, prebiotics are safe. However, sometimes unwanted side effects can occur if a person intolerant to soluble fiber takes prebiotics. According to prebiotic supplement reviews, the best way to avoid the side effects is to spread the recommended dosage of prebiotics throughout the day or reduce the dose. In other words, we advise individuals with such sensitivities to start with small doses and increase them as tolerance develops. Most importantly, always consult a healthcare professional before attempting to self-medicate with any dietary supplement.

How to Choose the Best Prebiotic Supplement for You?

Here are the key factors to consider when picking the right prebiotic supplement for you and your family.

General Quality

You want to get a high-quality dietary supplement that only contains the essential ingredients. In other words, added artificial colors, artificial flavors, hydrogenated oils, titanium dioxide, magnesium silicate, and hypoallergenic rice flour are substances that have no place in a high-quality supplement.

Above all, be cautious of brands that do not show the complete list of ingredients on their official website and the product’s label. It is a big red flag, so avoid these brands and products.

Best Prebiotic Supplement Types

The four main, completely natural types of prebiotics that you should purchase include:

  • pectin (can be found in apples)
  • galactooligosaccharides (GOS; can be found in beans and dairy products)
  • fructooligosaccharides (FOS; can be found in asparagus and garlic)
  • inulin (can be found in bananas, Jerusalem artichokes, and leeks)

Many brands list ingredients such as agave, dextrin, and lactulose as prebiotics. In case you find these ingredients, understand that they are not “real” prebiotics. To clarify, these ingredients have qualities similar to those of prebiotics, but they are not the same thing.

Preferences and Special Dietary Needs

If you are a vegan or vegetarian, you want to pick the best-rated prebiotics for people on a plant-based diet. Likewise, if you have any other dietary preferences, triple-check the label for any ingredients you may have overlooked. If you are allergic to gluten, soy, dairy, or any other ingredient, you will want to get an allergen-free product.

Final Thoughts

Everyone can benefit from a high-quality prebiotic supplement, not just people with gut-related issues. If you want to make your stomach even happier, then we recommend pairing prebiotics with probiotics or opting for a product that offers the best of both worlds. Hopefully, these prebiotic supplement reviews and the detailed guide helped you choose a suitable product. Remember, ultimate health starts with your gut!

FAQs

Is apple cider vinegar a prebiotic?

In the traditional sense, apple cider vinegar is not a probiotic, nor is it a prebiotic. However, natural apple cider vinegar has some similar gut-friendly properties.

According to experts, apple cider vinegar contains beneficial bacteria as it is fermented. However, studies lack proof of whether the bacteria in ACV can survive in the digestive system.

Can probiotics and prebiotics be used together?

Yes, they can! Probiotics and prebiotics can be mixed, and the effectiveness of probiotics can be boosted with good prebiotic supplements. In case you have missed our top recommendations for the best probiotic and prebiotic blends, check out our reviews above.

Which foods are rich in prebiotics?

Yes, prebiotic supplements are a simple, effective way to keep your gut happy and healthy. However, your priority should be to consume a well-balanced, whole-food-based diet before opting for any dietary supplement. Because dietary supplements are just that — they are an addition to an already balanced diet.

So, what are the different foods rich in good prebiotics? Here is a list of some of the foods you should start eating more of for good gut health:

  • garlic and onion
  • sweet potato
  • leek
  • artichoke
  • banana
  • asparagus
  • chicory root
  • dandelion greens
  • oats
  • barley
  • apples
  • cocoa
  • flaxseeds
  • burdock root
  • seaweed

Remember, besides taking the best prebiotic supplement for your particular needs, you should include plenty of fiber-rich foods into your diet.
