coenzyme Q10 mitigates statin-associated muscle symptoms

In plain terms: Does CoQ10 relieve statin-related muscle pain?

Contested Supplements 🔬 Includes disconfirming

Part of: 🧪 coenzyme Q10

RefutedContestedStrong support
consensus score -0.07

Genuinely uncertain—meta-analyses split down the middle, and much statin muscle pain is a nocebo effect, so don't count on it.

What the evidence shows

CoQ10 for statin-associated muscle symptoms is **genuinely contested** — meta-analyses split. A 2025 MA (7 RCTs, n=389) found a significant pain reduction (WMD −0.96), but an earlier 2020 MA found no significant improvement in myalgia or statin adherence. Mechanistically plausible (statins deplete CoQ10 via the shared mevalonate pathway), but the clinical signal is small, heterogeneous, and confou

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
