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
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
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%.
Purine Nucleotide Precursors in Preventing Myocardial Ischemia-Reperfusion Injury
International journal of molecular sciences (2025) · Systematic review
Depletion of cardiac nucleotides and compromised myocardial mechanical function are linked to both acute myocardial ischemia and decompensatory remodelling of the myocardium in heart failure.
Pharmacological and nutritional treatment for McArdle disease (Glycogen Storage Disease type V)
The Cochrane database of systematic reviews (2014) · Meta analysis · n=85
Oral ribose caused diarrhoea and symptoms suggestive of hypoglycaemia including light-headedness and hunger.
D-ribose metabolic disorder and diabetes mellitus
Molecular biology reports (2024) · Systematic review
Additionally, certain in vitro experiments have indicated that exogenous D-ribose exposure could trigger apoptosis in specific cell lines.
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.
Based on single crossover trial with nicotinamide/D-ribose combination (RiaGev). 27% NADP+ increase observed at 1520mg twice daily. Limited to 7-day study period.
AI-estimated from published studies. Interpret as directional guidance.
Both CoQ10 and D-Ribose are closely matched — the best choice depends on your specific health goals.
For support heart health, CoQ10 has a higher relevance score (80 vs 55).
No known interactions between CoQ10 and D-Ribose have been documented in our database. However, always consult a healthcare provider before combining supplements.
