Only one RCT reported adverse events, and they found that patients had no adverse effects or symptoms following supplementation.
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

Cochrane Database Syst Rev (2020) · Meta analysis
Cochrane: phlebotonics probably reduce edema (moderate-certainty evidence)
Phlebotonics for haemorrhoids.
Cochrane Database Syst Rev (2012) · Meta analysis
Phlebotonics improved hemorrhoid symptoms (bleeding, itching, discharge)
Based on heart failure meta-analysis (n=1573) showing mortality reduction. Effectiveness conservative due to single primary study (n=420). Take with food to reduce GI upset. Ubiquinol forms may have better absorption.
