Coenzyme Q10 (Ubiquinol)
Enhances mitochondrial energy production and acts as a lipid-soluble antioxidant — critical for heart health and depleted by statins.
What the evidence says
CoQ10 appears to help in 16 of 20 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 2007–2026 with a typical study size of 326 participants.

CoQ10 has an evidence score of 9/10 — very strong evidence based on 63 indexed studies, including 25 meta-analyses. Enhances mitochondrial energy production and acts as a lipid-soluble antioxidant — critical for heart health and depleted by statins.
The commonly studied dose of CoQ10 is 100-300mg daily. Research points to an estimated optimal dose around 300mg, with a minimum effective dose near 100mg. Individual response varies — start low and adjust.
The best time to take CoQ10 is in the morning. Take it with food. Coenzyme Q10 is a highly lipophilic benzoquinone that is virtually unabsorbable without co-ingested dietary fat.
Nicotinamide Riboside
Mostly mechanism / observationalA vitamin B3 precursor that efficiently raises cellular NAD+ levels, supporting energy metabolism, mitochondrial function, and healthy aging.
Berberine
Likely helpsActivates AMPK to regulate blood sugar, improve insulin sensitivity, and support lipid metabolism — comparable to metformin in some trials.

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.

Ubiquinol is 2-8x better absorbed than ubiquinone, especially important for those over 40. Quality brands include Kaneka QH.
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.
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.
Reduced fatigue and better energy levels
May reduce statin-related muscle pain
Improved heart function markers
Limited data; generally considered safe but consult doctor
Strongly recommended to replenish depleted CoQ10
May be particularly beneficial; use ubiquinol form
May reduce warfarin effectiveness; monitor INR
May have additive blood pressure lowering
Consult oncologist; may affect some drug actions
Tip: Take with food; split doses
Tip: Take in morning

CoQ10 is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are GI upset, insomnia. Use caution if any of these apply to you: None at recommended doses.
