Coenzyme Q10: CoQ10
Can you get CoQ10 naturally from foods?
The amounts of CoQ10 in found naturally in food is much lower than that found in supplements. Good food sources of CoQ10 include:
- Cold water fish, like tuna, salmon, mackerel, and sardines
- Vegetable oils
- Meats
What are the risks of taking CoQ10?
- Side effects from CoQ10 seem to be rare and mild. They include diarrhea, nausea, and heartburn.
- Risks. People with chronic diseases such as heart failure, kidney or liver problems, or diabetes should be wary of using this supplement. CoQ10 may lower blood sugar levels and blood pressure. Doses of more than 300 milligrams may affect liver enzyme levels.
- Interactions. People taking blood thinners and thyroid medications should check with their doctors before using CoQ10 supplements.
Given the lack of evidence about its safety, CoQ10 supplements are not recommended for children or for women who are pregnant or breastfeeding.
