In one study, taking coenzyme Q10 supplements did not raise levels of the compound in muscle tissue, meaning its pain-relieving effect may work through another pathway, not by simply replacing what statins deplete.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A randomized trial with muscle biopsies would determine whether oral CoQ10 supplementation increases intramuscular CoQ10 concentration in statin users and whether this change correlates with pain reduction.
A double-blind RCT with muscle biopsy sampling at baseline and 12 weeks in 60 statin-treated adults with SAMS, randomized to 300 mg/day ubiquinol or placebo, measuring intramuscular CoQ10 via HPLC and correlating change with VAS pain score reduction, controlling for statin type and baseline serum CoQ10.
A systematic review of all published muscle biopsy studies in statin users taking CoQ10 would synthesize evidence on whether supplementation consistently increases intramuscular CoQ10.
A systematic review and meta-analysis of all published studies measuring intramuscular CoQ10 before and after oral supplementation in statin-treated patients, including biopsy data from at least 5 studies with standardized methods, to calculate pooled mean difference in muscle CoQ10 concentration.
A prospective cohort would determine whether changes in serum CoQ10 levels predict changes in intramuscular CoQ10 and whether either predicts pain reduction over time.
A prospective cohort of 100 statin users taking CoQ10 supplements, measuring serum CoQ10 weekly and intramuscular CoQ10 via biopsy at baseline and 12 weeks, with daily pain logs, to assess correlation between serum, muscle, and symptom changes.
A case-control study would compare intramuscular CoQ10 levels between statin users who responded to supplementation and those who did not, to determine if low baseline levels predict response.
A matched case-control study comparing intramuscular CoQ10 levels in 30 responders (≥3-point VAS reduction) and 30 non-responders to CoQ10, matched for statin type, dose, and duration, with biopsy performed after 12 weeks of supplementation.
A cross-sectional study would compare intramuscular CoQ10 levels between statin users taking supplements and those not taking them, at a single time point.
A cross-sectional study measuring intramuscular CoQ10 via biopsy in 50 statin users taking CoQ10 supplements and 50 matched controls not taking supplements, adjusting for statin type, dose, and duration, to assess association.
