Probiotics vs Prebiotics: What's the Difference?

Gut health is having its moment, and with it comes a whole lot of conversation around probiotics and prebiotics. You've probably seen both mentioned in conversations about digestive health, but what actually makes them different?

Although their names sound similar, probiotics and prebiotics play different roles in supporting your gut microbiome. And understanding how they work is a useful first step towards making more informed choices about your gut health. So, do you need one, both or neither? Let's explore.

What Are Probiotics?

Probiotics are live microorganisms, usually bacteria, that can provide health benefits when consumed in adequate amounts. They work by interacting with the microorganisms already living in your digestive system, collectively known as your gut microbiome. Found in certain fermented foods and probiotic supplements, these microorganisms may help support your gut, although their effects depend on the specific strain and your individual needs.

What Are Prebiotics?

Probiotics introduce beneficial microorganisms; prebiotics help nourish the ones already living in your gut.

Prebiotics are substances, often types of dietary fibre, that are selectively used by beneficial microorganisms, helping support their growth or activity. Alongside a fibre-rich diet, prebiotic supplements offer another way to introduce specific prebiotic ingredients into your routine when appropriate.

Probiotics vs Prebiotics: What's the Difference?

The simplest way to understand the difference? Think of your gut as a garden.

Probiotics are like introducing new plants, while prebiotics provide some of the nourishment that helps your existing garden thrive.

Both interact with your gut microbiome, but they do so differently.

What Are the Benefits of Probiotics and Prebiotics?

Your gut microbiome is home to trillions of microorganisms involved in everything from digestion to immune function. Certain probiotic strains have shown potential benefits for specific digestive concerns, while prebiotic fibres can support beneficial bacterial activity and, in some cases, bowel regularity.

But the conversation doesn't stop at digestion. Researchers are also exploring the connection between gut health and skin health, often referred to as the gut-skin axis. For more information, explore our guide to supporting your gut health.

Which Foods Contain Probiotics and Prebiotics?

You don't necessarily need supplements to introduce more microbiome-friendly foods into your diet.

Foods containing live microorganisms include:

• Live yoghurt with suitable cultures

• Kefir

• Certain traditionally fermented vegetables

Not every fermented food contains live microorganisms with proven probiotic benefits, so it's worth checking what you're buying.

Foods containing prebiotic fibres include:

• Garlic and onions

• Leeks and asparagus

• Bananas

• Chicory root

• Oats

Including a variety of fibre-rich plant foods is a good starting point for supporting a diverse gut microbiome.

Should You Take Probiotic or Prebiotic Supplements?

Not necessarily. A balanced, varied diet may already provide much of what you need to support everyday digestive health. The important thing is understanding why you're taking them. Some probiotic strains have evidence for particular digestive concerns, but that doesn't mean every probiotic will deliver the same results. If you're experiencing persistent bloating, abdominal discomfort or changes in bowel habits, speak to your GP rather than relying on supplements alone.

How to Choose the Right Probiotic or Prebiotic

With so many formulations available, choosing a supplement isn't always straightforward.

When comparing products, consider:

• Probiotic strains: Look for clearly identified strains supported by evidence relevant to your goals.

• CFUs: Colony-forming units indicate the number of viable microorganisms, but a higher number doesn't automatically mean better results.

• Prebiotic ingredients: Check the type and quantity of fibre, especially if you're prone to bloating.

• Quality and dosage: Choose reputable brands and follow their storage and serving instructions.

Your wider nutritional needs matter too. Through our partnership with NOA, you can access personalised nutritional guidance, blood testing and expert nutritionist support to better understand your overall health.
