What it does
Think of CoQ10 as the spark plug inside your cells. It helps turn the food you eat into usable energy in your mitochondria, the tiny power plants that keep your muscles, brain, and heart running. Your body makes its own, but levels naturally fall with age and drop further if you take a cholesterol-lowering statin, which is when many people notice fatigue or achy muscles.
The science
CoQ10 (Ubiquinol) is central to mitochondrial electron transport and ATP production. Levels decline with age and are depleted by statins.
Most relevant for
Adults 40+, statin users, and anyone chasing steady all-day energy.
