About Us

JUVIA™ Digestive Balance Formula is a groundbreaking food supplement activated by our unique ingredient ERME™. Our scientists discovered that the active digestive enzymes in ERME help break down carbohydrates before they can cause problems.

Based in the UK, JUVIA is part of Ateria Health Ltd, a science-backed health and wellness company.

Our history

JUVIA was created as a result of decades of world-leading studies and scientific research projects carried out by our founders - Professor John Hunter and Dr Rosemary Waring. As leaders in the field of gut health, their expertise extends beyond the human microbiome and wellness through to the wellbeing and gut health of animals too.

Our history begins with lunch! Professor Hunter met with a leading equine veterinarian and former president of the British Equine Veterinary Association. He asked Professor Hunter to compare the guts of humans and horses, which led to the paper ‘Do Horses Suffer From IBS?’ in the Equine Veterinary Journal.

From here, Professor Hunter was asked to study the horses of a leading world renowned racehorse trainer. It was at this point he linked up with Dr Waring, who suggested using the enzymes in malt to improve racehorse performance. The racehorse diet is high in carbohydrates, so Professor Hunter and Dr Waring’s work discovered this natural, enzyme-rich product broke down these carbohydrates.

It was soon discovered that the same active component ERME™, which is derived from barley - could help humans too.

How it all started

Sarah was the first person to try JUVIA back in 2016.

“Working alongside Professor Hunter meant that I was lucky enough to be exposed to cutting edge science on the microbiome and its effect on the gut.” Sarah says.

In 2016, Professor John Hunter’s work with Dr Rosemary Waring had resulted in a digestive supplement that could be used to reduce digestive symptoms in racehorses. Seeing containers of the supplement in the office, Sarah decided she’d try it for herself, becoming the first person to take the supplement.

“Within days I felt different. I couldn’t believe the difference, honestly.” Sarah explains. “I told Professor Hunter what I’d done and it was from there that work started to make the supplement which would later be known as JUVIA. It has changed my life and I would not be without it now. I feel fitter and less stressed as I don’t have to worry what I eat or where the nearest loo is.”
