Co-enzyme Q-10 is an endogenous substance that the body can produce itself and that can also be taken as a part of the daily diet. Normally 3-5 g are consumed with the daily diet. Particularly rich quantities of the co-enzyme Q-10 are found in the flesh of organs such as the liver or in fatty meat, nuts, legumes and many seeds.
Many types of vegetable such as potatoes, cabbage or spinach contain the co-enzyme Q-10, too. But one of the major disadvantages of taking it in daily nutrition is that cooking and frying, strong heat in general, can destroy the co-enzyme.
