CoQ10 and PQQ are often grouped as mitochondria supplements, yet they answer different evidence questions. Use foundational supplement stack thinking before paying for a "mitochondria complex."
Decision criteria
We compare evidence maturity, use-case fit, dose clarity, medication cautions, and ability to run a meaningful trial.
| Feature | CoQ10 | PQQ |
|---|---|---|
| Evidence maturity | Broader human literature | Smaller human literature |
| Main use context | Statin-associated questions, migraine prevention, heart-adjacent care | Fatigue and oxidative-stress marketing |
| Dose format | Ubiquinone or ubiquinol | Pyrroloquinoline quinone salts |
| Main caution | Warfarin and care-team review | Limited long-term high-dose data |
| First test | More defensible | More speculative |
Practical read
CoQ10 has a larger clinical literature, especially outside general wellness. That does not make it a universal energy supplement. The most defensible use is when a clinician or clear rationale exists, such as statin discussions, migraine prevention protocols, or cardiometabolic care.
PQQ has interesting mechanistic and early human data, yet product marketing often outruns the evidence. If someone wants to test PQQ, Unfair would frame it as a low-priority experiment after sleep, iron status when relevant, thyroid review, diet, training load, and medication effects.
Trial protocol
| Phase | CoQ10 or PQQ rule |
|---|---|
| Baseline | Two weeks of fatigue, sleep, training, and caffeine logs |
| Selection | Choose one compound, not a mitochondria blend |
| Dose | Use a transparent label and food-consistent timing |
| Review | Judge fatigue and function after 4-8 weeks |
| Stop | Rash, insomnia, GI effects, medication conflict, or care-team concern |
Disclosure
Unfair does not sell CoQ10 or PQQ. Product entries should record form, dose, brand, and reason for use because "mitochondria support" is too broad to evaluate.
