Efficacy and Safety of Coenzyme Q10 Supplementation in the Treatment of Polycystic Ovary Syndrome: a Systematic Review and Meta-analysis

Coenzyme Q10 for heart failure
The Cochrane database of systematic reviews (2021) · Meta analysis · n=1573
Coenzyme Q10 probably reduces the risk of all-cause mortality more than control (RR 0.58, 95% CI 0.35 to 0.95; 1 study, 420 participants; number needed to treat for an additional beneficial outcome (NNTB) 13.3; moderate-quality evidence).
Antioxidants for female subfertility

This suggests that among subfertile women with an expected clinical pregnancy rate of 22%, the rate among women using antioxidants would be between 27% and 33%.
All three points come from one 4-week double-blind trial in newly diagnosed type 2 diabetes (PMID 21211558), which gave bitter melon 500, 1,000 or 2,000 mg a day against metformin 1,000 mg. Only 2,000 mg lowered fructosamine significantly (-10.2 µmol/L), and less than metformin did. 500 and 1,000 mg did not, so they are plotted as no effect. The trial had no placebo arm and did not test higher doses, so it cannot set an optimal dose or a safety ceiling. The Cochrane review (PMID 22895968, 4 trials, 479 participants) found no significant difference from placebo, and no two trials used the same preparation.
