Probiotics vs Prebiotics: What’s the Difference and Why Does It Matter?

There has been a lot of talk about probiotics and prebiotics in recent years. While they sound similar, they serve different purposes in the body. So, what is the difference between probiotics and prebiotics, and why does it matter?


Probiotics are live bacteria and yeasts that are good for your overall health, especially your digestive system. These live microorganisms are similar to the good bacteria found naturally in your gut. Probiotics can be found in various foods, supplements, and fermented products such as yogurt, kefir, kimchi, and sauerkraut.

The benefits of probiotics are vast. They help balance the harmful bacteria in your gut, aid in digestion, boost your immune system, and promote healthy skin. Research has also shown that probiotics may help with certain health conditions like irritable bowel syndrome (IBS), diarrhea, and urinary tract infections (UTIs).

One important thing to note is that not all probiotics are created equal. The type and strain of probiotic can determine the benefits they provide. It’s important to research the specific strains and their benefits before choosing a probiotic supplement or food source.


Prebiotics are a type of fiber that our body cannot digest. They serve as food for the good bacteria in our gut, helping them to grow and thrive. Prebiotics are found in many plant-based foods such as onions, garlic, bananas, asparagus, and artichokes.

While prebiotics themselves do not provide the health benefits of probiotics, they are essential in promoting the growth of good bacteria in the gut. Essentially, prebiotics feed the probiotics. Consuming a diet rich in prebiotics can help improve digestion, promote regularity, and boost overall gut health.

The Differences

The main difference between probiotics and prebiotics is that probiotics contain live microorganisms that provide health benefits to the host, while prebiotics serve as food for these microorganisms. Essentially, prebiotics create an environment in the gut that is conducive to the growth and proliferation of probiotics.

Additionally, while probiotics can be found in many different forms and products, prebiotics are primarily found in plant-based foods. Prebiotics are a type of soluble fiber, which means they are not broken down by the body and instead reach the colon where they are fermented by the gut bacteria.

Why It Matters

Gut health is essential in maintaining overall health and wellness. An imbalance of harmful bacteria in the gut can lead to various health conditions such as digestive issues, autoimmune disorders, and even mental health problems.

Consuming a diet rich in probiotics and prebiotics can help promote a healthy gut microbiome. Additionally, consuming probiotics and prebiotics is essential for those on antibiotics, which can wipe out both the harmful and beneficial bacteria in the gut. Consuming probiotics and prebiotics during and after a course of antibiotics can help replenish the beneficial bacteria and promote gut health.

Overall, while probiotics and prebiotics may sound similar, they serve different roles in maintaining gut health. Both are essential in promoting a healthy gut microbiome, which can lead to improved overall health and wellness.
