Probiotics vs. Prebiotics: What’s the Difference?

One of the most popular health topics today revolves around the gut and the role of good bacteria in maintaining overall health. You may have heard of probiotics and prebiotics, but what are they and what’s the difference between them?

Probiotics

Probiotics are live microorganisms that live in the gut and confer health benefits to the host. They are often referred to as “good bacteria”. Some of the most common probiotics are lactobacillus and bifidobacteria. Probiotics are commonly found in fermented foods such as yogurt, kefir, sauerkraut, and tempeh. They can also be taken as supplements in the form of capsules, tablets, or powders.

Probiotics have been shown to have a number of health benefits including:

Improved digestion and absorption of nutrients
Boosting the immune system
Reducing inflammation
Preventing and managing certain types of diarrhea
Managing and treating certain skin conditions
Managing and treating certain mental health conditions

However, not all probiotics are created equal. Different strains of bacteria have different health benefits, and they need to be administered in adequate amounts to be effective. It’s also important to note that the FDA does not regulate the quality, safety, or effectiveness of probiotics, so it’s important to do your research and choose a reputable brand.

Prebiotics

Prebiotics, on the other hand, are not live microorganisms, but rather indigestible carbohydrates that serve as food for the good bacteria in the gut. They are often referred to as “food for probiotics”. Some of the most common prebiotics are fructooligosaccharides (FOS) and inulin. Prebiotics are commonly found in fruits, vegetables, and whole grains.

Prebiotics have been shown to have a number of health benefits including:

Increasing the number and diversity of good bacteria in the gut
Improving digestion and absorption of nutrients
Reducing inflammation
Boosting the immune system
Managing and treating certain mental health conditions
Reducing the risk of certain diseases such as heart disease, diabetes, and obesity

Like probiotics, not all prebiotics are created equal. Different types of prebiotics have different health benefits, and they need to be consumed in adequate amounts to be effective. It’s also important to note that some people may experience digestive discomfort such as gas and bloating when consuming prebiotics.

The Bottom Line

In short, probiotics and prebiotics are both important for maintaining a healthy gut and overall health. Probiotics are live microorganisms that confer health benefits to the host, while prebiotics are indigestible carbohydrates that serve as food for the good bacteria in the gut. Both probiotics and prebiotics have been shown to have a number of health benefits, but it’s important to choose the right strains and types in adequate amounts to be effective. As always, it’s important to consult with your healthcare provider before starting any new supplements.
