What are polyphenols?
Varied

Polyphenols are a diverse class of secondary plant metabolites often found in fruits and vegetables. With their unique, naturally-occurring chemical structures, these tiny powerhouses deliver a rainbow of diverse functions. This impact stems from their action in the gut (colon), where they give beneficial bacteria the boost they need to thrive. The result? A host of essential health benefits, in the gut and beyond.

Versatile

The immense potential of polyphenols to support gut health is finally getting the attention it deserves. With their recent recognition as a ‘novel prebiotic’ by major international regulators and growing evidence to support their health effects, polyphenols offer an opportunity to create a wide variety of science-backed prebiotic supplements that stand out in today’s crowded nutraceutical market.

Science snapshot:
How polyphenols work within the body

Between the effects of disease, stress and poor diets, our colon’s protective mucosal lining can become compromised, leading to microbiome imbalance, increased growth of ‘bad’ bacteria and an overall poor gut health. With their ability to resist digestion and pass into the colon intact, polyphenols have been shown to restrict the growth of harmful bacteria and promote that of beneficial bacterial strains like Akkermansia muciniphila, Bifidobacteria and Lactobacilli. What’s more, they also help re-establish the immune-supporting function of the colon’s mucosal epithelial barrier and reduce the impact of oxidative stress.

What’s so special about elderberry polyphenols?

Naturally rich in polyphenols including anthocyanins, European black elderberries (sambucus nigra) have been a feature of traditional cold and flu remedies for centuries. Recently, researchers at Johannes Kepler University, Austria set out to investigate how these health-boosting effects could be harnessed to support the gut microbiota, with some surprising results.
