What does the research say about CoQ10?

strong evidence

CoQ10 (and its reduced form ubiquinol) is essential for mitochondrial ATP production. Levels decline with age and are depleted by statins. Strongest evidence: heart failure, statin-associated muscle pain, migraine prevention.

Best-evidenced use cases
  • Statin-associated muscle symptoms
  • Heart failure (adjunct)
  • Migraine prevention
  • Age-related fatigue
  • Fertility support (egg quality)

How we read the research

We prioritize randomised controlled trials and meta-analyses over single observational studies. Animal and in-vitro data are listed as "mechanistic", they suggest direction, not human effect size.

What we don't do

We don't cherry-pick favourable studies, omit conflicting evidence, or cite industry-funded trials without flagging the conflict of interest where known.

Make it actionable

The research is one thing, what to take, at what dose, paired with what, is another. We compose stacks that turn the evidence into a daily routine.
