Prebiotics vs. Probiotics: What’s the difference and why do you need both

When we think about gut health, we often go straight to probiotics. And fair enough, they’re the ‘good bacteria’ that help keep our digestion running smoothly.
But many people don’t realise that probiotics can’t do their job correctly without prebiotics.
In other words, if you take probiotics but do not support them with prebiotics, you might only see half the benefits.
That’s where Harmony of the Gods Prebiotic by Hercules Supplements* comes in. It is a thoughtful blend of both prebiotics and probiotics, working together to help your gut feel balanced, energised, and supported.

Imagine planting a garden (your probiotics) but never watering it (the prebiotics).
Without that nourishment, those good bacteria may never have a chance to settle in and do what they’re meant to do, especially in older adults whose digestive systems may already be stressed.
Scientific research backs this up: combinations of prebiotics and probiotics (synbiotics) are proven to perform better than probiotics alone regarding digestion, immunity, and overall gut balance.

Gut health is about more than just staying regular. It’s connected to how we feel every day.
An imbalanced gut can cause bloating, fatigue, skin issues, low mood, poor sleep, and even brain fog.
And these days, it’s easy for that balance to slip. Antibiotics, processed food, stress, alcohol, and even sleepless nights can chip away at our healthy gut bacteria.
So, while probiotics can help, they need fuel to flourish. Without prebiotics, those helpful bacteria may not make it very far, and you may wonder if your supplement is doing anything.

Harmony of the Gods* is specially formulated to offer complete gut support* by combining both:
With Harmony of the Gods*, you’re not just feeding your gut. You’re helping it thrive.

What’s the difference between prebiotics and probiotics?
To put it simply:- Probiotics are live, beneficial bacteria that support your gut microbiome and immune system.
- Prebiotics are the non-digestible fibres that feed those bacteria, helping them grow, survive, and thrive.
