Roll Call does not check drug interactions or assess personal safety.

A compound the body produces naturally and also obtains in small amounts from meat and fish, involved in cellular energy production.

Why it’s used

Taken to support heart health and energy, and sometimes to offset statin-associated muscle discomfort.

What the evidence is for

possible modest effect on heart failure symptoms and statin-associated muscle pain, evidence inconsistent.

What the evidence says

NIH ODS notes CoQ10's clear biological role in cellular energy metabolism, but clinical trial evidence for supplement effects on heart failure symptoms, statin-associated muscle pain, or migraine frequency is mixed and generally modest, not strong enough to be considered settled.

Dose studied

100–300 mg — doses studied for heart failure symptoms and statin-associated muscle pain.

Context

Trials have generally used doses of roughly 100-300 mg/day, often continued for several months before any effect was assessed.
