our story
At root we understand the importance of a healthy gut. It’s one of the major causes of health problems today. This is not surprising when you consider it is the area of the body which is most exposed to the outside world. After all, it is our gut lining which decides on what to absorb into the body and what to reject.
Root postbiotics have been designed to provide the gut with what it actually needs. Our gut formula removes the limitations and problems that off the shelf probiotics face resulting in a faster and more efficient route to a happy gut.
why take postbiotics?
For probiotics, the gut is like an obstacle course. Only a very small percentage of the probiotics you eat will survive this obstacle course and are able to have a positive effect on your body.
Root postbiotics however, don’t play by the same rules. The same obstacles which probiotics face don’t apply to postbiotics. As a result, the body is able to use almost all of the postbiotics you eat, so you and your gut health are performing at your best.
your fast track to gut happy
probiotics
(live bacteria)
- Probiotic bacteria must make it to the gut alive to exert health benefits
- Most probiotic bacteria can be destroyed by stomach acid and don't make it to the gut
- Are wasted by the body unless they come into contact with prebiotics in the gut
- The strength of probiotic supplements deteriorate quickly in transit and on the shelf
postbiotics
(heat-killed, cultured bacteria)
- Postbiotics are the beneficial compounds created by probiotics in the gut
- Postbiotics are stomach acid resistant and are not destroyed before reaching the gut
- Compounds the gut actually needs to exert health benefits for efficient absorption
- The strength of postbiotic supplements do not deteriorate quickly, you get all of the goodness
what is the microbiome?
Your Microbiome is the vast ecosystem of organisms (microbiota) such as bacteria, yeasts and fungi that live within the gut. Collectively, the 100 trillion gut microbiota in your gut are heavier than the average brain, and are vital in regulating your immune system, digesting food, metabolism, producing vitamins and even maintaining mental wellbeing.
The gut is known as your body’s second brain, and the Gut-Brain Axis goes some way in explaining this. Look after it, and it will look after you!

My passion for health began after university, running fitness boot camps before opening a series of healthy food cafés across the North West of England.
Despite living what I believed was a healthy lifestyle, I spent years struggling with IBS and constipation. Searching for answers led me deep into the science of the gut microbiome, where I became fascinated by probiotics, prebiotics and, ultimately, postbiotics. The more I learned, the more I realised how difficult it was to find products I genuinely trusted. I was particularly drawn to the stability of postbiotics compared with many traditional probiotic formulations that rely on live bacteria remaining viable.
Knowing I wasn’t a scientist, I partnered with experienced microbiome researchers and formulation specialists to develop a product grounded in science rather than marketing.
Root Biotics exists because I wanted to create the company I had been searching for myself - one built on transparency, evidence and products people can rely on.
