These pills have already been approved by European health authorities who have agreed that they help the health of the heart. Callebaut, which supplies the chocolate for Magnum ice-creams, has said it will team up with French nutrition supplement makerNaturex to produce and sell an extract of flavanols. Two of the largest chocolate making companies, Mondelez International Inc. – which makes Cadbury Dairy Milk chocolate - and Marcs Inc. are considering European sales of a range of flavanols capsules and powders. Mondelez International Inc. is researching the benefits of flavanols in the hope of potentially using it in their products in the future. In May, Mars announced a five year study with Harvard University researchers to look more closely into the health benefits of flavanols. Mars’s website claims that if their own capsule containing flavanols, called CocoaVia is taken daily, it promotes good health as they encourage blood flow.
