Meat and fish are the richest source of dietary CoQ<sub>10</sub> and levels over 50 mg/kg can be found in beef, pork and chicken heart, and chicken liver. Dairy products are much poorer sources of CoQ<sub>10</sub> compared to animal tissues. Vegetable oils are also quite rich in CoQ<sub>10</sub>. Within vegetables, parsley, and perilla are the richest CoQ<sub>10</sub> sources, but significant differences in their CoQ<sub>10</sub> levels can be found in the literature. [[Broccoli]], grape, and cauliflower are modest sources of CoQ<sub>10</sub>. Most fruit and berries represent a poor to very poor source of CoQ<sub>10</sub>, with the exception of [[avocado]], with a relatively high CoQ<sub>10</sub> content.
* The mineral [[selenium]] is essential for the body's natural production of Coenzyme Q10.
*cholesterol-lowering drugs -- actually deplete your body’s natural CoQ-10. Statins block production of cholesterol in the liver, where CoQ-10 is also manufactured. Without sufficient CoQ-10, statins can cause liver damage ... irregular heartbeat ... muscle weakness ... leg cramps ... heart attack and stroke (the two potentially fatal conditions that statins are supposed to prevent).
*Other medications also can limit your body’s production of CoQ-10, including: Diabetes drugs ... antidepressants ... female hormone replacement therapy ... and blood pressure meds. If you take any of these, you definitely need to supplement with CoQ-10.
