When discussing fatigue, a distinction between perceived fatigue and performance fatigability, the two facets contributing to its definition, is of capital importance (Enoka and Duchateau, 2016)

Headaches: Mild headaches can occur, particularly if you are dehydrated
It could also have some effect on lipid parameters, which, together with the above, may reduce cardiovascular morbidity and mortality.31 Learning and memory Studies in mice support the use of CoQ10 for cognition and memory, though human trials are few and far between.13 Pulmonary function Patients with chronic lung disease performed better at several exercise metrics in a study that employed a 90mg CoQ10 dose over eight weeks.14 Migraines In a meta-analysis of six studies, CoQ10 reduced the frequency and duration of migraine attacks, though it didnt have an effect on attack severity.15 Fertility Some of the best evidence supporting CoQ10s use in fertility comes from this review involving women undergoing fertility treatments, in which doses ranging from 180mg to 1,200mg resulted in more successful pregnancies than placebo.16 Men may also see a fertility benefit, with evidence suggesting that a 200mg dose is sufficient to significantly improve semen parameters.32 Because CoQ10 production declines with age, supplementation simply replaces the CoQ10 that would otherwise be there
More recent systematic reviews and meta-analyses published between 2020 and 2022 have broadly confirmed this picture, reporting small, short-term reductions in body weight and body mass index, particularly in older adults and individuals with obesity or metabolic conditions, but with effect sizes that remain clinically modest
