Although ubiquinol can be obtained through diet by eating oily fishes, organ meats or whole grains, it is difficult to get high levels without eating excessive amounts of these foods. For example, sardines are one of the most ubiquinol-rich foods, but you would need to eat 33 pounds of sardines to get 100 mg of ubqiuinol. That's 120 cans of sardines at a cost of $240 every day.
Ubiquinol that naturally occurs in foods such as chicken also converts back to the ubiquinone form of CoQ10 when it is cooked, and ubiquinone is more difficult for your body to absorb and use. Learn more about the difference between CoQ10 and ubiquinol. Below is a list of foods that are naturally rich in ubiquinol and the amounts you would need to ingest to reach the recommended daily dose of 100 mg versus taking one 100 mg Kaneka Ubiquinol™ supplement.
