Dutch health ingredients companies NutriLeads said a peer-reviewed publication shows the immune modulating properties of its proprietary pectin-derived rhamnogalacturonan-I (RG-I) polysaccharides in the journal Nutrients.

RG-I are natural, plant-derived compounds (polysaccharides) that interact with the gut bacteria (microbiota) and the host innate immune system. In selected traditional plant extracts, such pectic polysaccharides have previously been shown to have immunostimulatory effects. However, these traditional remedies are often expensive, derived from non-renewable sources, and could face regulatory challenges.

In this recent publication, NutriLeads showed that RG-I can be extracted from affordable and renewable crops, namely carrots and bell peppers, and even obtained from side streams of crop processing, allowing for sustainable and scalable production. RG-I from both carrot and bell pepper showed immune stimulating and microbiota modulating activity in vitro. Furthermore, bell pepper RG-I was shown to enhance innate immune responsiveness in a proof-of-concept trial in humans.

“We are delighted to share these new data, demonstrating the immunomodulatory effects of plant-based RG-I, which have the potential to bring health benefits to us all. We are particularly pleased that we can successfully derive RG-I from sustainable and widely available sources,” said Ruud Albers, PhD, CEO of NutriLeads.
