Coenzyme Q10 supplementation decreases statin-related mild-to-moderate muscle symptoms: a randomized clinical study

Open access

Abstract

BACKGROUND: Statin use is frequently associated with muscle-related symptoms. Coenzyme Q10 supplementation has yielded conflicting results in decreasing statin myopathy. Herein, we tested whether coenzyme Q10 supplementation could decrease statin-associated muscular pain in a specific group of patients with mild-to-moderate muscle symptoms. MATERIAL/METHODS: Fifty patients treated with statins and reporting muscle pain were recruited. The Q10 group (n=25) received coenzyme Q10 supplementation over a period of 30 days (50 mg twice daily), and the control group (n=25) received placebo. The Brief Pain Inventory (BPI) questionnaire was used and blood testing was performed at inclusion in the study and after 30 days of supplementation. RESULTS: The intensity of muscle pain, measured as the Pain Severity Score (PSS), in the Q10 group was reduced from 3.9±0.4 to 2.9±0.4 (P<0.001). The Pain Interference Score (PIS) after Q10 supplementation was reduced from 4.0±0.4 to 2.6±0.4 (P<0.001). In the placebo group, PSS and PIS did not change. Coenzyme Q10 supplementation decreased statin-related muscle symptoms in 75% of patients. The relative values of PSS and PIS significantly decreased (-33.1% and -40.3%, respectively) in the Q10 group compared to placebo group (both P<0.05). From baseline, no differences in liver and muscle enzymes or cholesterol values were found. CONCLUSIONS: The present results show that coenzyme Q10 supplementation (50 mg twice daily) effectively reduced statin-related mild-to-moderate muscular symptoms, causing lower interference of statin-related muscular symptoms with daily activities.

  • Five included studies did not report a washout period and statin rechallenge necessary to confirm that myalgia was related to statin treatment.

    “Importantly, five studies did not report a washout period and statin rechallenge necessary to confirm that myalgia was related to statin treatment [5,6,8,9,17].”

    From Effect of Coenzyme Q10 on statin-associated myalgia and adherence to statin therapy: A systematic review and meta-analysis (2020) · cites this paper as [6]

    The Methods (Patients; page not available) explicitly report statin de-challenge and re-challenge before enrollment, with symptoms recurring afterward. The Results (Patient characteristics; page not available) also report that statin discontinuation lasted no more than two weeks in a subgroup. Thus, this study did report the rechallenge that the citing sentence says was absent. (LLM, conf=0.91)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Only two of the seven included studies disagree with this result in their conclusions, and the eighth study in the qualitative review did not favour CoQ10 treatment.

    “Only two of the seven included studies disagree with this result in their conclusions [5,6], and the eighth study in the qualitative review did not favour CoQ10 treatment [18].”

    From Effect of Coenzyme Q10 on statin-associated myalgia and adherence to statin therapy: A systematic review and meta-analysis (2020) · cites this paper as [6]

    The citation [18] is attached to the claim that the eighth study did not favour CoQ10 treatment. This paper’s Conclusions (page unavailable) say the opposite: CoQ10 supplementation significantly reduced statin-associated muscle pain in patients with mild-to-moderate symptoms. (LLM, conf=0.95)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Two included studies reported a significant reduction in muscle pain in the CoQ10 treated group compared to placebo, while the remaining six did not find a significant reduction.

    “A significant reduction in muscle pain in the CoQ10 treated group compared to placebo was reported in two studies, while the remaining six studies did not find a significant reduction in pain score [5,6].”

    From Effect of Coenzyme Q10 on statin-associated myalgia and adherence to statin therapy: A systematic review and meta-analysis (2020) · cites this paper as [6]

    The Results (‘Intensity of myopathic pain’; page not supplied) report significantly less muscle pain in the CoQ10 group than in the placebo group, so this paper supports one positive-study result. Its Discussion describes conflicting findings in earlier studies but does not establish the claimed tally of two positive and six negative studies. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Three studies reported a run-in period in which patients stopped statin intake prior to trial start to assure that myopathic pain and other side effects were caused by statin intake.

    “Of all seven studies, three studies reported a run-in period in which patients were asked to stop statin intake prior to the start of the trial to assure that the myopathic pain and other side effects are caused by the statin-intake.(34,40,41)”

    From Effects of coenzyme Q10 supplementation on myopathy in statin-treated patients: a systematic review and meta-analysis (2025) · cites this paper as [34]

    The Material and Methods > Patients section says patients underwent statin de-challenge and re-challenge before enrollment to establish the association with muscle symptoms. The Results > Patient characteristics section also reports a brief statin discontinuation for some patients. The paper does not describe this as a formal run-in period or say that the procedure established the cause of other side effects; it cannot establish the count of three studies. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • A number of randomised controlled trials have reported that CoQ10 reduces statin-associated muscle symptoms, while others have failed to demonstrate a benefit.

    “A number of these RCTs have reported that CoQ10 reduces SAMS [4-7], while other have failed to demonstrate a benefit [8-12].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
