Coenzyme Q10

Coenzyme Q10 (CoQ10) or ubiquinone is found in the mitochondria and as a component of the electron transport chain plays an important role in aerobic respiration.

Evidence
A trial of 50 mg CoQ10 taken with 5mg NADH twice daily for eight weeks found improvements in exercise performance/less exercise intolerance and a less fatigue and improved cognitive function, but those in the placebo group had better sensory and affective pain scores.

Plasma CoQ10 was found to be significantly lower in ME/CFS patients than in normal controls and correlated with symptom severity. A literature review found that CoQ10 was marginally deficient in people with chronic fatigue syndrome.

Ubiquinol-10 supplementation can improve autonomic nervous function and cognitive function in chronic fatigue syndrome.
