What the study showed, in plain terms

This study measured CoQ10 in commonly eaten foods and combined the results with national food-consumption data. Average intake was estimated at 3–5 mg/day, with meat and poultry contributing most of the total.

Frying destroyed about 14–32% of CoQ10 in the tested foods, while boiling did not produce detectable destruction.

Key findings

Average CoQ10 intake was estimated at 3–5 mg/day.

Meat and poultry accounted for about 64% of estimated daily intake.

Frying reduced CoQ10 content by roughly 14–32%, while boiling caused no detectable loss in the tested samples.

What this study can and cannot tell us

The estimates reflect Danish dietary patterns and food samples from the 1990s and may not represent every country or modern diet.

The study quantified food exposure and processing effects; it did not test whether dietary CoQ10 improves health outcomes.
