Efficacy and Safety of Coenzyme Q10 Supplementation in the Treatment of Polycystic Ovary Syndrome: a Systematic Review and Meta-analysis
Reproductive sciences (Thousand Oaks, Calif.) (2023) · Meta analysis · n=1021
Meta-analysis of 9 randomised trials with 1,021 women with polycystic ovary syndrome.
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
The Cochrane database of systematic reviews (2017) · Meta analysis · n=6510
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%.

Among 284 participants (88% men; mean age: 51 y; BMI: 31.2 kg/m2; APOE-ε4 genotype = 15.7%), 224 (79%) completed the trial with eligible whole-brain MRIs.

Effect of the mitophagy inducer urolithin A on age-related immune decline: a randomized, placebo-controlled trial
Nature aging (2025) · Rct · n=50
Exploratory single-cell RNA sequencing demonstrated UA-driven transcriptional shifts across immune populations, modulating pathways linked to inflammation and metabolism.
Both doses come from the first-in-human trial in healthy sedentary older adults (PMID 32694802), where 4 weeks of 500 mg or 1,000 mg modulated plasma acylcarnitines and muscle mitochondrial gene expression, with a favourable safety profile at every dose tested. The abstract does not rank the two doses, so the curve is flat. A 4-month trial of 1,000 mg in 66 adults aged 65 to 90 (PMID 35050355) also lowered acylcarnitines and C-reactive protein, but found no gain in maximal ATP production, a direct measure of mitochondrial function. These are biomarkers, not clinical outcomes, and no dose above 1,000 mg was tested.
