Does research support the addition of coenzyme Q10 (CoQ10) for those on lipid-lowering medication?—MARY SAFRANSKI, FNP, APRN-BC, Barnesville, Minn.

CoQ10 has been shown to be an essential factor for a myriad of cellular functions, especially hepatic and musculoskeletal. Among the many things that can affect the function and production of CoQ10 are cholesterol-lowering statins. Several trials indicate a reduction in statin-related myalgias when CoQ10 was used and fewer incidences of elevated liver enzymes. While CoQ10 supplementation is not a guarantee against statin-related problems, the evidence certainly supports not only the concept but modest efficacy as well.
