Proven Benefits

01Reduces oxidative stress markers
02May improve endothelial function
03May lower liver enzymes in hep C
04May lower inflammatory markers

Chemical Forms

Recommended
  • MitoQ (mitoquinone mesylate)
Avoid
  • Standard CoQ10 or ubiquinol (does not accumulate in mitochondria)
  • Generic 'mitochondrial support' blends without disclosed mitoquinone content
Expert Note

MitoQ is a patented molecule that conjugates ubiquinone to a triphenylphosphonium cation to selectively accumulate in mitochondria. Standard CoQ10 or ubiquinol reach far lower concentrations in the mitochondrial matrix due to the inner membrane barrier, so they do not replicate MitoQ's targeted antioxidant effect.

Protocol

Amount
10-20 mg
Frequency
Once daily
When
Morning with food to minimize nausea; absorption does not depend on dietary fat.

Condition-Based Dosing

General antioxidant support in healthy adults
10 mg daily
Older adults targeting vascular function
20 mg daily

Safety & Limits

Upper Safe Limit
20 mg/day (highest dose studied in long-term trials); no official UL established.
Cycling
Safe for continuous use

Contraindications

Warfarin or other vitamin K antagonists — potential reduction in anticoagulant efficacy
Pregnancy and breastfeeding — insufficient safety data
Severe liver disease — limited clearance data

Synergies

Omega-3

Omega-3 fatty acids support vascular endothelial function and may complement MitoQ's antioxidant effects on arterial health.

Avoid Combining With

  • ✕Warfarin and anticoagulants (potential interaction via quinone structure — consult clinician)
  • ✕Other mitochondrial antioxidants (redundant, theoretical risk of redox imbalance)
