Coenzyme Q10 (CoQ10) is essential for cellular energy production. Levels decline with age and statin use. Coq10 benefits have evidence for several specific uses.
Evidence-supported uses
Heart failure: Some evidence for symptom improvement, mortality reduction. Q-SYMBIO trial supportive.
Migraine prevention: Reasonable evidence. 100-300 mg daily.
Statin-induced muscle pain: Some evidence for symptom reduction. Mixed results across studies.
Fertility: Some evidence for egg and sperm quality.
Periodontal disease: Some topical evidence.
Ubiquinone vs Ubiquinol
- Ubiquinone (oxidized): cheaper, body converts to ubiquinol
- Ubiquinol (reduced/active): more bioavailable, more expensive
- For older adults or those with absorption issues, ubiquinol may be preferred
- For most people, ubiquinone adequate
Dosing
- 100-300 mg daily for most uses
- Up to 600 mg for heart failure
- Take with food (fat-soluble)
- Effects develop over weeks-months
Safety
Generally very safe:
- Mild GI side effects possible
- Theoretical interaction with warfarin
- Limited drug interactions otherwise
