Probiotics vs. Prebiotics: What’s the Difference—and Why Advanced ProV Keeps It Simple

Probiotics vs. Prebiotics: What’s the Difference—and Why Advanced ProV Keeps It Simple

Jul 21, 2025Vicki Fletcher

If you’ve ever browsed the supplement aisle, you’ve probably noticed products labelled as “probiotics,” “prebiotics,” or even “synbiotics.” At Royal Oak Health, we believe good health should be simple—and that’s why Advanced ProV is a probiotic-only supplement. Here’s why that matters—and how it could make a real difference for your gut. 

So… What’s the Difference Between Probiotics and Prebiotics? 

Let’s break it down: 

  • Probiotics are live, friendly bacteria—like Lactobacillus and Bifidobacterium—that help keep your gut healthy. Think of them as your gut’s good guys, working hard to keep things balanced and support your digestion and immune system. 

  • Prebiotics are types of fibre (like inulin or FOS) that feed the good bacteria in your gut. They’re the “food” probiotics love to munch on so they can thrive. 

Sounds Great… So Why Not Combine Them? 

For many people, combining probiotics and prebiotics (sometimes called synbiotics) is perfectly fine. But here’s the catch: 

Prebiotics can cause bloating, gas, and discomfort—especially if you have a sensitive gut, IBS, or certain digestive issues. 

Everyone’s gut is unique. Some people thrive on prebiotics. Others… not so much. 

Many people prefer getting prebiotics naturally from food like onions, garlic, bananas, and oats, rather than from supplements. 

Why Advanced ProV Is Probiotic-Only 

Advanced ProV is all about keeping things simple and gentle. We’ve chosen to make it a pure probiotic supplement without prebiotics for a few very good reasons: 

1. Gentler on Sensitive Guts 

If you’ve ever taken a supplement that left you bloated or uncomfortable, prebiotics could be the culprit. By leaving them out, Advanced ProV is less likely to cause digestive upset—perfect if your gut needs a little TLC. 

2. Puts You in Control 

Not everyone wants or needs prebiotics in a supplement. With Advanced ProV, you can choose whether to add prebiotics through your diet or a separate supplement, giving you total flexibility. 

3. Clean and Simple Formula 

Some people want only probiotics—nothing else. No sweeteners. No fibres. No surprise ingredients. Just the good bacteria your gut needs. 

Advanced ProV delivers 14 carefully selected strains and 25 billion live cultures per capsule at manufacture—all without any extras you might not want. 

4. Less Risk of Interactions 

Prebiotics can sometimes interact with: 

  • Low-FODMAP diets 

  • Certain health conditions 

  • Medications 

By keeping Advanced ProV strictly probiotic, we keep things simpler and safer for more people. 

When Are Prebiotics Helpful? 

Prebiotics can be beneficial for many people. They help feed good bacteria and produce important compounds that keep your gut lining strong. But they’re not essential for everyone—and for those with sensitive digestion, they can be too much of a good thing. 

The Royal Oak Health Approach 

At Royal Oak Health, we believe good health should fit your body. That’s why Advanced ProV focuses purely on delivering powerful, clinically researched probiotics to help support your digestion, reduce bloating, and keep your immune system strong. It’s a simple, effective way to care for your gut—no fibres, sweeteners, or extras required. 

Want to add prebiotics? Great! You can easily do that through food or a separate supplement. But with Advanced ProV, you’re always in control.
