What are Prebiotics?

Prebiotics are types of fibers that support your gut bacteria. These fibers help your gut probiotic bacteria to survive, thrive, and flourish in the digestive tract. The prebiotic fibers used in prebiotic supplements include:

Galactooligosaccharides (GOS)

GOS is a type of prebiotic found naturally in breast milk. It is composed of chains of sugar galactose that vary in length. The primary function of GOS fiber is to support the growth of bifidobacteria in the gut. These fibers are prepared in laboratories to add them to supplements.


Inulin is one of the most common fibers available in various prebiotic supplements. It is also found in onions, Jerusalem artichokes, fruits, and vegetables and contains larger chains of fructose sugar.

Fructooligosaccharides (FOS)

As its name suggests, it contains chains of fructose sugar. Fructose-the natural sugar is available in plants, vegetables, and various fruits. Many prebiotic supplements contain chicory root as a source of FOS. Few other rich sources of FOS are onions, garlic, bananas, leeks, and asparagus.

Remember, we are not talking about Probiotics!

Probiotics are the bacterial species that reside in your lower intestine; they break down food and absorb calories to enhance the microbiome’s function.

These probiotics are present in trillions of numbers in your body and need great prebiotic supplements to flourish. Prebiotics are extracts of the plant, fiber-rich compounds, and natural ingredients to fuel up the bacteria in your intestine.

Health Benefits Of Prebiotics

Prebiotic supplements are becoming increasingly popular due to their beneficial effects on gut health.

Prebiotics’ promising function promotes your digestive tract’s health and reduces weight, boosts immunity, and reduces the risk of common diseases.

Gut health has a significant correlation with the overall health and fitness of the body. As per the studies, the body contains 39 to 300 trillion bacteria, and all these Probiotics require nutrients and fuel to thrive and support your digestion. Research shows that gut bacteria ratio to cells in our body is 10:1, while other studies report this ratio as 1:1.

Whatever the ratio is, these bacteria play an essential role in digestion and improve gut health. A healthier gut promotes healthy skin, enhances immunity, reduces the risk of several diseases, and manages weight.

Some people recommend probiotic supplements that mainly contain the strains of Lactobacillus and Bifidobacteria families.

In contrast, research shows that prebiotics, such as inulin, fructooligosaccharides, and galactooligosaccharides, are more effective. They support the probiotics in your body and improve the health of your gut.

Moreover, prebiotics also help in reducing weight. It minimizes hunger between meals, thus decreasing calories intake, reducing craving for unhealthy food, and digesting the food you eat, thus extracting all its nutrients and energy.

Research stated that people who include fibers (found in prebiotic supplements listed above) in their diet had decreased chances of gaining weight.

If you suffer from constipation, bloating, or gassiness, then prebiotics is for you. A study on patients with irritable bowel syndrome (IBS) showed a reduction in flatulence with prebiotic supplements.

The bacteria in your gut ferment the fiber into short-chain fatty acids that nourish your brain and nervous system. The gut bacteria consume these short-chain fatty acids, affecting the pH level, therefore protecting the gut wall lining.

A study shows that prebiotics by their action on probiotics can improve depression, autism, anxiety, poor memory, and obsessive-compulsive disorder symptoms.

Are Prebiotic Supplements Free Of Side Effects?

Studies reveal that most people do not face any side effects after consuming prebiotics. Many foods that you eat also contain prebiotics, so you must take supplements after consulting your Physician.

People with gastrointestinal disorders, IBS, FODMAP, and small intestinal bacterial overgrowth (SIBO) may experience some side effects with prebiotics. However, if you take the standard dose of Prebiotic (2.5 g to 10 g per day), you may not experience side effects.

A study conducted in 2019 states that a dose of 5 grams of prebiotic decreases flatulence; however, increasing the amount to 20grams did not. Thus, taking prebiotics within the usual dosage maximizes the benefits and reduces side effects.

Standard Dosage Of Prebiotic Supplements

According to numerous studies, the standard dosage of most prebiotics ranges between 2.5 grams to 10grams. At this dosage, you will have maximum beneficial effects and minimum side effects.

Increasing the dose may not offer any extra advantage to your gut; however, you may suffer from side effects.

If you are unsure of the dose of any specific prebiotic supplement, check the label on the package or consult your doctor.

How We Rank The Prebiotic Supplements?

You might be wondering how we rank all the above supplements. Every company claims that its product is best in supporting your gut health and minimizing digestive issues. However, all supplements cannot be beneficial for you.

Therefore, we have picked a few prebiotic supplements that we have ranked based on many factors. Some of those factors are:

Organic Certification

Some of the prebiotic supplements have undergone a strict evaluation procedure for obtaining organic certification. Attaining USDA certification is complex and requires a higher standard and quality of products. The supplements which are USDA certified will have top quality; therefore, we have considered this factor in our ranking.

Natural Ingredients

We evaluate most prebiotic supplements primarily based on their composition. Those containing plant extracts, herbs, fibers, or naturally accruing products are superior in our list. Supplements containing artificial flavors and other additives may cause side effects; thus, users avoid those.

Variety Of Prebiotic Fibers

Some of the prebiotic supplements include only one type of fiber, while others have multiple. Those supplements containing inulin, fructooligosaccharides, galacto-oligosaccharides, or other fibers in a single frame are on our top list. It is because each fiber has its different activities and is beneficial for your gut health.

Science-Backed Composition

The science-backed ingredients are prebiotic fibers, bacteria strains, and digestive enzymes. These ingredients have proven results and efficiency as per the research; therefore, we consider this our ranking factor.

Optimum Dosages

A supplement can only be effective if it contains the optimum dose of each ingredient. Many companies add great ingredients to their product but not in optimum quantities. We choose those supplements that include the right amount of each ingredient, as it increases the efficiency and safety of that product.

Manufacturer Transparency

We believe the manufacturers and companies are transparent in disclosing all the information related to the product. If a company hides product ingredients, proprietary labels, or location, we do not consider them in our list of best products.

Doctor Formulated Products

The prebiotic supplements that a doctor or nutritionist formulates are best. Doctors or the medical advisory board verifies not all supplements.

Price Of Products

We have listed the product from lower to higher price range. Whether you have to spend less or more, you will get the prebiotic supplement in your price range. We consider those products as our top priority, which offers the best effects at a low cost.

User Friendliness

Some supplements are in the form of a capsule, others in powder form. Supplements in powder form are mixed with the beverages, making them easy to consume. Also, some are flavorless, and others have flavored formulas. We have mentioned both so you can select as per your choice.

Risk Factors

Along with the beneficial effects, supplements can also pose adverse effects on the body. The supplements with low-risk factors and side effects are on our list of best products. We recommend you check the pros and cons of each supplement you take.
