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.[1]
Plasma CoQ10 was found to be significantly lower in ME/CFS patients than in normal controls and correlated with symptom severity.[2] A literature review found that CoQ10 was marginally deficient in people with chronic fatigue syndrome.[3]
Ubiquinol-10 supplementation can improve autonomic nervous function and cognitive function in chronic fatigue syndrome.[4]
