CoQ10
Coenzyme Q10 (Ubiquinol)
A vital compound for cellular energy production, particularly beneficial for heart health, energy, and those on statins.
Coenzyme Q10 is essential for mitochondrial energy production and acts as a powerful antioxidant. Production declines with age and is depleted by statin medications. Ubiquinol (reduced form) is better absorbed than ubiquinone, especially in older adults.
Mechanisms of Action
ATP Production
Essential for cellular energy generation
Antioxidant Defense
Protects cells from oxidative damage
Heart Support
Supports heart muscle function
Recommended Dose
100-300mg daily
Optimal Timing
- With fatty meal
Take with food
Best Form
Ubiquinol (reduced form)
Alternatives: Ubiquinone (oxidized form), Ubiquinol softgels
Ubiquinol is 2-8x better absorbed than ubiquinone, especially important for those over 40. Quality brands include Kaneka QH.
Duration
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Fat-soluble; must take with fat-containing meal. Can be taken any time of day. Some split dose AM/PM.

Zhang T et al. • Reproductive sciences (Thousand Oaks, Calif.) (2023)
“The Author(s), under exclusive licence to Society for Reproductive Investigation.”
Key Findings:
- Only one RCT reported adverse events, and they found that patients had no adverse effects or symptoms following supplementation.
- The Author(s), under exclusive licence to Society for Reproductive Investigation.
- Further research warranted to confirm findings
Al Saadi T et al. • The Cochrane database of systematic reviews (2021)
“The included studies provide moderate-quality evidence that coenzyme Q10 probably reduces all-cause mortality and hospitalisation for heart failure.”
Key Findings:
- 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).
- There was low-quality evidence of inconclusive results between the coenzyme Q10 and control groups for the risk of myocardial infarction (RR 1.62, 95% CI 0.27 to 9.59; 1 study, 420 participants), and stroke (RR 0.18, 95% CI 0.02 to 1.48; 1 study, 420 participants).
- Coenzyme Q10 probably reduces hospitalisation related to heart failure (RR 0.62, 95% CI 0.49 to 0.78; 2 studies, 1061 participants; NNTB 9.7; moderate-quality evidence).
Showell MG et al. • The Cochrane database of systematic reviews (2017)
“In this review, there was very low-quality evidence to show that taking an antioxidant may provide benefit for subfertile women, but insufficient evidence to draw any conclusions about adverse events.”
Key Findings:
- 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%.
- Heterogeneity was moderately high.There was insufficient evidence to determine whether there was a difference between the groups in rates of miscarriage (OR 0.79, 95% CI 0.58 to 1.08, P = 0.14, 18 RCTs, 2834 women, I2 = 23%, very low quality evidence).
- This suggests that, among subfertile women with an expected miscarriage rate of 7%, use of antioxidants would be expected to result in a miscarriage rate of between 4% and 7%.
- There was also insufficient evidence to determine whether there was a difference between the groups in rates of multiple pregnancy (OR 1.00, 95% CI 0.73 to 1.38, P = 0.98, 8 RCTs, 2163 women, I2 = 4%, very low quality evidence).

“The use of certain dietary supplements has resulted in a significant decrease in migraine prophylaxis.”
Key Findings:
- In adults, compared with placebo, these supplements did not significantly affect other outcomes, and omega-3 supplementation did not yield a statistically significant reduction in any of these outcomes.
- The use of certain dietary supplements has resulted in a significant decrease in migraine prophylaxis.
- Further clinical trials of high quality appear to be beneficial.
Michaelsen MP et al. • Nutrients (2025)
“This study found no convincing evidence of an effect of any dietary supplements on male infertility.”
Key Findings:
- This study found no convincing evidence of an effect of any dietary supplements on male infertility.
- Larger and more well-conducted randomized controlled trials focusing on specific supplements and considering pregnancy outcomes are needed.
- Further research warranted to confirm findings
