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.
More Energy
Reduced fatigue and better energy levels
Statin Side Effect Relief
May reduce statin-related muscle pain
Cardiovascular Support
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
Who Should NOT Take This
- None at recommended doses
Drug Interactions
May reduce warfarin effectiveness; monitor INR
May have additive blood pressure lowering
Consult oncologist; may affect some drug actions
Possible Side Effects
Tip: Take with food; split doses
Tip: Take in morning
Warnings
- Use ubiquinol form for better absorption
- Especially important for statin users
- May take several weeks for effects
