Prebiotics vs Probiotics: What's the Difference and Do You Need Both?

The terms prebiotic and probiotic are often used interchangeably, but they serve very different — and complementary — roles in your gut health.

What Are Probiotics?

Probiotics are live microorganisms — bacteria and sometimes yeasts — that provide health benefits when consumed in adequate amounts. Think of them as soldiers you're adding to your gut army.

What Are Prebiotics?

Prebiotics are specialised plant fibres that act as food for your beneficial gut bacteria. While probiotics add new bacteria, prebiotics feed and strengthen the bacteria already living in your gut.

Do You Need Both?

The short answer is yes. Taking probiotics without prebiotics is like planting seeds without watering them. The combination — called a synbiotic — produces the best results for overall gut health.
