Cura discovered that Koji had the ability to take up high amounts (up to 10% of its biomass) of minerals, including iron, zinc, copper, chromium, calcium, selenium, manganese, and molybdenum alone or together in one fermentation. More than 90% of the elemental iron present in the Ultimine™ Iron, which has 8-10% iron, is stored within the cell structure.

The macro composition of Ultimine™ of at least 30-40% protein and 25-30% carbohydrates supports it as a whole-food mineral source. This ability of Koji to encapsulate high amounts of minerals, provide an innovative approach to slow release bioavailable iron, for example, with reduced iron overload and oxidative stress. Furthermore, it is possible with this technology to deliver in one product at least 30% DV of main trace minerals.
