CoQ10 participates in electron transport used to make cellular ATP.
Coenzyme Q10 is a compound your body makes and uses in cellular energy production. It can also act as an antioxidant.
What it is
Coenzyme Q10 is a compound your body makes and uses in cellular energy production. It can also act as an antioxidant.
You do not need to turn this into a chemistry lesson. The useful part is understanding what researchers know, where it shows up in food, and what that means in everyday eating.
What research discusses
CoQ10 participates in electron transport used to make cellular ATP.
CoQ10 can move between oxidized and reduced forms.
Reduced CoQ10 can act as an antioxidant in lipid environments.
Supplemental CoQ10 has been studied in several clinical contexts, with results depending on the condition and study design.
How much you need
Recommended amounts depend on the nutrient, age, sex, and life stage. Some compounds do not have an established Dietary Reference Intake.
Use the authoritative source below for the current RDA, AI, upper limit, or other guidance that applies to CoQ10.

You do not need to memorize this list. These are everyday examples of foods that can contribute CoQ10. Amounts can change with serving size, variety, preparation, and fortification.

Make it useful
Knowing what is in your food is useful. Knowing what to do with it is better. Pick a food. Find a recipe. See what you already have. Plan the meal. Buy what is missing. Then go eat food.

A little context matters
No Dietary Reference Intake has been established for CoQ10. Supplements can interact with medicines, including warfarin, and should be discussed with a healthcare professional when medication is involved.
Food and supplements are not the same thing. Supplements can deliver much larger doses. Medications, pregnancy, kidney or liver function, allergies, and other health circumstances can change what is appropriate.
