Welcome to the Mars Edge Cocoa Flavanol Science Hub

Our Vision

At Mars Edge, we collaborate with a global network of leading scientific partners to further research into cocoa flavanols and health – and contribute to better lives through nutrition. We do so because we believe that:


Health is more than the absence of disease
Health is more than the absence of disease

We believe it’s important to establish biomarkers of health when assessing the impact of nutrition, rather than rely solely on a definition of health based on the "absence of disease."


Nutrition has a massive impact on health

We believe insights into the role of dietary status and nutrient intake are key to our health.


Bioactives show huge promise

In the context of a healthy diet, we believe there is a need to broaden today’s essential nutrient-centric approach and include bioactive food constituents in scientific assessment and, if warranted, in recommendations for diet and health.


Biomedical research has shown the benefits of cocoa flavanols

Research shows dietary flavanols–including those derived from cocoa–offer important benefits to human health. For more than 20 years, we have been studying cocoa flavanols to understand their role in supporting health and, potentially even improving outcomes related to certain diseases.

New tool validated to compare & estimate cocoa flavanol content

A new independently validated tool will enable scientists to convert cocoa flavanol numbers measured using different analytical methods to a single, accurate standard.

In the research paper, titled “Evolution of cocoa flavanol analytics: impact on reporting and cross-study comparison” and published in Food and Function, the team consulted experts in the field to develop the tool which gives researchers the ability to compare past and present findings on the health effects of cocoa flavanols.

Diet quality and increased flavanol intake may be linked to improved memory

Diet quality and dietary flavanols may be linked to age-related memory function and could have an important role to play in slowing declines associated with normal aging.

A recent collaboration between Columbia University’s Irving Medical Centre and Mars Edge used concentrated cocoa extract capsules to investigate the effects of cocoa flavanols on memory and cognitive performance. Chocolate was not used in this study and the findings should not be linked to chocolate.

COSMOS (the Cocoa Supplement and Multivitamins Outcome Study) is the largest clinical dietary intervention examining the impact of intake of cocoa flanavols and multivitamins on health and risks of heart disease, stroke and cancer.

It examines 22,000 generally healthy men and women over 60 in the U.S., and takes place over 5 years. The trial is run by Brigham and Women’s Hospital, an affiliate of Harvard Medical School, and the Fred Hutchinson Cancer Research Center.
