OBJECTIVE: To evaluate whether antioxidant supplements presumed to target specific cellular compartments affected cerebrospinal fluid (CSF) biomarkers. DESIGN: Double-blind, placebo-controlled clinical trial. SETTING: Academic medical centers. PARTICIPANTS: Subjects with mild to moderate Alzheimer disease. INTERVENTION: Random assignment to treatment for 16 weeks with 800 IU/d of vitamin E (α-tocopherol) plus 500 mg/d of vitamin C plus 900 mg/d of α-lipoic acid (E/C/ALA); 400 mg of coenzyme Q 3 times/d; or placebo...

Coenzyme Q(10) (CoQ(10)) is an essential electron carrier in the mitochondrial respiratory chain and an important antioxidant. Deficiency of CoQ(10) is a clinically and molecularly heterogeneous syndrome, which, to date, has been found to be autosomal recessive in inheritance and generally responsive to CoQ(10) supplementation. CoQ(10) deficiency has been associated with five major clinical phenotypes: (1) encephalomyopathy, (2) severe infantile multisystemic disease, (3) cerebellar ataxia, (4) isolated myopathy, and (5) nephrotic syndrome...

Coenzyme Q(10) (CoQ(10)), an obligatory cofactor in the aerobic respiratory electron transfer for energy generation, is formed from the conjugation of a benzoquinone ring with a hydrophobic isoprenoid chain. CoQ(10) is now used as a nutritional supplement because of its antioxidant properties and is beneficial in the treatment of several human diseases when administered orally. Bioprocesses have been developed for the commercial production of CoQ(10) because of its increased demand, and these bioprocesses depend on microbes that produce high levels of CoQ(10) naturally...

Myalgia is the most frequently reported adverse side effect associated with statin therapy and often necessitates reduction in dose, or the cessation of therapy, compromising cardiovascular risk management. One postulated mechanism for statin-related myalgia is mitochondrial dysfunction through the depletion of coenzyme Q(10), a key component of the mitochondrial electron transport chain. This pilot study evaluated the effect of coenzyme Q(10) supplementation on statin tolerance and myalgia in patients with previous statin-related myalgia...
