CoQ10 is a naturally occurring compound found in various foods, particularly those rich in healthy fats and nutrients. One of the primary dietary sources of CoQ10 is oily fish, such as salmon, mackerel, and tuna, which are known for their high levels of this essential compound. Organ meats, such as liver, heart, and kidney, are another excellent source of CoQ10, as these tissues contain high concentrations due to their role in energy metabolism. Additionally, whole grains, such as wheat germ and bran, contribute moderate amounts of CoQ10 to the diet. These foods are vital for maintaining adequate levels of CoQ10 in the body, which is important for cellular energy production and for protecting cells from oxidative stress. While the body can produce some CoQ10 naturally, dietary intake is crucial, especially as levels tend to decrease with age.
