What the Research Says

Meta-Analysis · Rosenfeldt et al., 2007

CoQ10 significantly improves cardiac output in heart failure

Meta-analysis of 13 RCTs: CoQ10 supplementation improved ejection fraction, cardiac output, and functional class in heart failure. CoQ10 is essential for mitochondrial electron transport.

PMID 16908601 →

RCT · Trammell et al., 2016

NR raises NAD+ required for mitochondrial biogenesis

NAD+ is required for SIRT1 and SIRT3 activation — sirtuins that regulate mitochondrial biogenesis (PGC-1α pathway) and mitochondrial protein deacetylation. NR supplementation raises NAD+ 2.7× in 6 weeks.

PMID 28904226 →

Review · Chowanadisai et al., 2010

PQQ stimulates mitochondrial biogenesis in cells and animals

PQQ (pyrroloquinoline quinone) acts as a redox cofactor and activates CREB and PGC-1α — transcription factors that drive formation of new mitochondria. Animal studies show significant mitochondrial biogenesis with PQQ supplementation.

PMID 17076168 →

Meta-Analysis · Welch et al., 2019

Exercise is the most potent mitochondrial biogenesis stimulus

Resistance and aerobic training (especially HIIT and Zone 2) are the most evidence-backed interventions for mitochondrial biogenesis. Supplement interventions are additive, not substitutes, for exercise-induced mitochondrial adaptations.

PMID 26741452 →

Frequently Asked Questions

What are the best mitochondrial supplements?

Strongest evidence: CoQ10/ubiquinol (electron transport chain, 13 RCT meta-analysis), NR/NMN (NAD+ for sirtuin activation, mitochondrial biogenesis). Emerging: PQQ (biogenesis activation in animal models), Alpha-lipoic acid (antioxidant recycling). Exercise (Zone 2 cardio, resistance training) is still the most potent mitochondrial stimulus — supplements are additive.

What is the difference between ubiquinone and ubiquinol?

CoQ10 exists in two forms: ubiquinone (oxidized) and ubiquinol (reduced, active). Ubiquinol is the form that directly participates in the electron transport chain and is the predominant form in the blood. Studies show ubiquinol has approximately 3× better bioavailability than ubiquinone. Ubiquinol is preferred for adults 40+ and anyone with impaired absorption. Younger adults may efficiently convert ubiquinone to ubiquinol.

Can mitochondrial supplements improve athletic performance?

CoQ10 has some RCT data showing improved VO₂ max and reduced exercise-induced oxidative stress in well-trained athletes at 300mg/day. NR/NMN shows improved muscle function in older adults. However, the effect sizes are modest compared to training adaptations. These supplements are more relevant for recovery and long-term mitochondrial preservation than acute performance gains.

What damages mitochondria?

Key mitochondrial stressors: excessive and unbroken sedentary time, chronic sleep deprivation, excessive alcohol, sustained high-calorie diets, environmental pollutants, and some medications (especially statins, metformin at high doses, some antibiotics). Conversely: regular aerobic and resistance exercise, time-restricted eating, cold exposure, and adequate micronutrients (B vitamins, magnesium, coenzyme Q10) support mitochondrial function.
