NutriLeads’ clinical trial demonstrates that daily intake of BeniCaros helps support protective innate immune responses

Pivotal study published in Nutrients showing that Nutrileads’ proprietary carrot-derived rhamnogalacturonan-I (cRG-I) (commercially known as BeniCaros) fiber, accelerates protective anti-viral immune responses and reduces symptoms after an experimental infection with common cold virus in humans.

20 January 2022, Wageningen, the Netherlands. Dutch health ingredients company, NutriLeads, announced the publication of the positive results of a pivotal clinical trial demonstrating that its award-winning ingredient cRG-I, commercially known as Benicaros, helps support protective immune responses to a common respiratory infection.      

The Dietary Intake of Carrot-Derived Rhamnogalacturonan-I Accelerates and Augments the Innate Immune and Anti-Viral Interferon Response to Rhinovirus Infection and Reduces Duration and Severity of Symptoms in Humans in a Randomized Trial” has been published in the open access journal Nutrients1.

Conducted in collaboration with the Amsterdam University Medical Centre (UMC; location AMC), NIZO Food Research, and StatistiCal B.V. in the Netherlands, the BeniCaros clinical trial assessed how the food ingredient carrot-derived rhamnogalacturonan-I (cRG-I) impacted peoples’ responses to an experimentally induced mild rhinovirus infection. Rhinoviruses are responsible for common colds and impose an enormous economic burden on society. In the randomized, double-blind, placebo-controlled trial, 146 healthy adults were given either cRG-I or the placebo for eight weeks, after which they were exposed to a standardized dose of an attenuated rhinovirus via the nose. In the clinical study, daily consumption of BeniCaros prior to the rhinovirus infection significantly accelerated protective innate immune and antiviral responses, resulting in a 20% reduction in severity of symptoms, and a 25% reduction in symptom duration. 

René Lutter, PhD, Principal Investigator at the Amsterdam UMC, who runs the rhinovirus challenge model in collaboration with NIZO, commented: “The impact of cRG-I on the immune response observed in this nutritional intervention study is the biggest that I have ever seen with this model. It is clinically relevant and especially exciting because fast innate antiviral and immune responses are important for limiting infections with respiratory viruses.” 

The ingredient cRG-I is a unique polysaccharide upcycled from carrot pomace, a by-product of carrot juice production. It has been developed as a natural food ingredient to promote healthy immune function as previously shown2. BeniCaros was launched for formulation in dietary supplements and functional food and beverages in the US in October 2021. 

Commenting on the publication and impact of the findings, Ruud Albers, PhD, CSO of NutriLeads, said: “This publication is the culmination of extensive work by numerous people over ten years, and I am grateful to all involved for their dedication. The unique design of this trial was essential to demonstrate that consumption of cRG-I as a dietary supplement accelerated protective anti-viral immune responses, reducing the symptoms triggered by a standardized infection with a common cold virus. With increasing awareness of immune health over the past years, the discovery that cRG-I trains the immune system to respond faster when needed, is timely and particularly relevant.  

These exciting results fully support our earlier findings with cRG-I2 and play an important role in supporting the launch of BeniCaros (cRG-I) our immune health ingredient. This publication is a significant milestone for the company as we progress in our mission to unlock the potential of clinically proven food ingredients”. 




NutriLeads launches clinically backed BeniCaros™ for sustainable, year-round immune support

October 1, 2021, Wageningen, The Netherlands – Dutch health ingredients company, NutriLeads, announced the launch of its proprietary immune health ingredient, BeniCaros™. Upcycled from carrot pomace, BeniCaros is developed for supplements and functional food & beverages, and it is clinically supported to help to prepare your immune system to be fit all year round.

NutriLead’s proprietary extraction process unlocks rhamnogalacturonan-I (RG-I), the polysaccharide that gives BeniCaros its potential to deliver a dual mechanism of immune support. BeniCaros and its benefits are based on many years of robust pre-clinical and clinical research providing evidence that daily consumption of BeniCaros prepares the healthy immune system to function at its best when it matters most. As little as 0.3 grams per day was shown to be effective in a pivotal clinical trial. BeniCaros works by supporting the immune system to become more responsive to potential threats and challenges while also stimulating beneficial gut microorganisms and their metabolites, which in turn support immune responses.

“I have been active in this field for more than 25-years and have never seen another ingredient with such distinctive data supporting its effectiveness. Our main clinical trial demonstrates unique and very consistent effects of BeniCaros,” said Dr. Ruud Albers, CSO of Nutrileads. “There are many immune health ingredient options out there, but very few that work like BeniCaros and even fewer that work with the same efficacy to support immune function. At a time when demand has surged for immune health solutions, we see BeniCaros as a clear and unique way to improve health and wellness.”

BeniCaros is a soluble fiber made using a proprietary process by upcycling carrot pomace, a side stream of carrot juice production. It is a sustainably produced, tasteless and odorless powder that does not use artificial additives, making it a very label friendly ingredient. BeniCaros can be formulated into most functional food, beverage and supplement formats and meets consumer demands for a sustainable, clean ingredient that makes a difference.

“Having worked with the NutriLeads team on the development of BeniCaros since 2015, I am thrilled that we can now launch BeniCaros and make its benefits available to consumers together with our partners, the food & beverage and supplement companies,” said Erik Dam, CEO of NutriLeads. “There is no better way to get these benefits. While you can eat carrots, and RG-I is a natural component of carrots, it requires our proprietary technology to fully unlock RG-I from the carrot and make it available in the gut where it can do its work. BeniCaros delivers superior benefits for optimal health outcomes at a time when consumers want and need it most.”

NutriLeads has signed its first agreements and is currently in further discussions with other food companies and supplement manufacturers to incorporate BeniCaros into dietary supplements and functional food and beverage products.

Scientific paper by NutriLeads shows that its plant-based RG-I food ingredients support immune function and modulate the microbiota

25 March 2021

  • First scientific data showing immune supportive properties of plant-based RG-I derived from bell pepper and carrot
  • Study published in the “Nutrition, Immunity and Viral infection” special issue of the peer-reviewed journal, Nutrients
  • Immune health is a top priority for today’s consumers with six in ten people looking for functional foods and beverages to support their immunity [1]

Dutch health ingredients innovator, NutriLeads, announces the first peer-reviewed publication of data proving the immune modulating properties of its proprietary pectin-derived rhamnogalacturonan-I (RG-I) polysaccharides in the journal Nutrients.[2]

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 shows 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.

Commenting on the publication and the expected impact of the findings, Ruud Albers, PhD, CEO of NutriLeads, said: “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.

Due to the pandemic, immune health is even higher on the agenda than ever before, and we believe that this research shows that dietary supplementation with RG-I from specific food crops is ideally suited to support immune function and modulate the microbiota. We are well advanced with generating additional evidence showing the immune benefits of carrot-derived RG-I and are working together with Food and Food Supplement companies to deliver these benefits to consumers in the second half of 2021.”

Demand for food supplements and food and beverage products with immune health properties has been growing sharply in recent years. The global immune health supplements market alone was estimated to be worth USD 16.32 billion in 2019 and is expected to reach USD 29.40 billion by 2027.[3] In addition, recent research shows that 64% of respondents will aim to improve their immunity in the next 12 months.[4]

NutriLeads’ lead ingredient, BeniCaros, extracted from carrot pomace (a side stream from carrot juice production), has been developed to support immune function. This ingredient is expected to be available in the US for the formulation of dietary supplements and functional foods in the second half of 2021.
