Manganese, another trace mineral, is also a cofactor in enzymatic reactions. The RDA for manganese is 2.3 milligrams per day, and it can be found in soybeans, raspberries, garlic and squash. Zinc, which is required for various enzymatic reactions in the liver, is found in liver, dried beans, red meat, grains and fruits, and the RDA is 11 milligrams per day.
