In short

It lowers blood pressure a little and reduces tiredness. The strongest case is for people on statins and adults over 40.

The bottom line

CoQ10 modestly lowers blood pressure and reduces fatigue in trials, with the strongest rationale for statin users and adults over 40 whose own production declines. Older claims of double-digit blood-pressure drops did not survive GRADE-assessed meta-analysis.

How it works

Electron carrier in mitochondrial ATP production and lipid-soluble antioxidant; statins block its synthesis.

Who it helps, and who it doesn't

Statin users, adults 40+, fatigue-prone populations. 100–300 mg with a fatty meal. May reduce warfarin effect.

What the studies measured

Every result, next to the line that means no effect

Each diamond is a study's best estimate. The thin line shows how sure the study was: the shorter the line, the more certain the result.

Each unit gets its own scale, so numbers are never mixed on one line. When a study gave no range, we leave it blank instead of inventing one.
