The science behind JUVIA™

The science behind JUVIA™

JUVIA was created to work with our individual gut flora – collectively known as our microbiome. It has been developed by leading gut health experts at Ateria Health Ltd, and is backed by years of research. Our founders - Professor John Hunter and Dr Rosemary Waring - are world-leading gut health experts, and developed JUVIA based on their work.

The research that has led to JUVIA was the first to establish that when the gut doesn’t digest food completely, especially carbohydrates, it can lead to the growth of unhealthy gut flora and this imbalance can irritate the gut.

Backed by cutting-edge research

The human gut is full of billions of bacteria with viruses and fungi, which are collectively known as ‘the microbiome’. In health, these components stay in balance. The bacteria help to regulate the immune system and protect against other bacteria that cause diseases. They also help to digest food, breaking it down (’fermenting’ it) to small molecules that are used for energy and metabolism. If too much carbohydrate is present or if the breakdown is inefficient (‘malfermentation’), then ‘bad’ bacteria thrive, producing toxic chemicals which irritate the gut. This unbalanced microbiome is thought to be linked with a number of health problems, including obesity, diabetes, immune function and irritable bowel syndrome (IBS).

Our product is based on decades of research into the gut health of both humans and animals, and is informed by findings from multiple studies.

How it works

JUVIA consists of a range of enzymes (including amylases and glucanases if you want to get technical), which help to break down starch and plant materials. Digestive enzymes are vital in helping to break down food so your digestive system can absorb them.

These starches are broken down into glucose and other simple carbohydrates early on in your digestive process, and provide energy. This means that there’s much less starch in your lower gut for mal-fermentation and other digestive troubles.


JUVIA contains our natural active ingredient ERME™. ERME is derived from UK-grown, sustainable barley. It contains high levels of natural enzymes that help with breaking down carbohydrates before they can cause problems in your gut.
