What Is PQQ?
PQQ (Pyrroloquinoline quinone) is a redox cofactor that is involved in a variety of biological processes, most notably as a key player in mitochondrial biogenesis. Found naturally in certain foods like kiwi, green pepper, and spinach, PQQ is also available as a dietary supplement.
How It Works
PQQ works primarily by promoting the growth of new mitochondria in cells, a process called mitochondrial biogenesis. Mitochondria are the powerhouses of cells, and more mitochondria mean more energy production. PQQ also serves as a potent antioxidant, combating oxidative stress and protecting cells from damage.
Who It's Best For
PQQ is ideal for individuals seeking to enhance cognitive function, boost energy levels, and support overall mitochondrial health.
Who Should Avoid It
Pregnant or breastfeeding women, individuals with medical conditions or those taking medication should consult with a healthcare professional before use.
Dosage & Usage Tips
Typically, a dosage of 20-40mg per day is recommended. PQQ is best taken in the morning with food to enhance absorption.
Buying Advice & Quality Tips
When selecting a PQQ supplement, look for products that are third-party tested for purity and potency. Avoid supplements with unnecessary additives or fillers.
Price & Value
PQQ supplements can be pricey, but the potential cognitive and energy benefits may justify the cost for many individuals.
Final Verdict
Overall, PQQ is a promising supplement for enhancing cognitive function and promoting mitochondrial health. While more research is needed, the current evidence supports its use for these purposes.
Additional Clinical Research
I have identified three published scientific studies that specifically investigate the effects of Pyrroloquinoline Quinone (PQQ) on various health aspects.

RESEARCH QUALITY ASSESSMENT:
- Studies employed randomized, double-blind, placebo-controlled designs, enhancing reliability.
- Sample sizes were relatively small, which may limit the generalizability of findings.
- Short intervention durations; long-term effects of PQQ supplementation remain unclear.
- Further large-scale, long-term studies are needed to confirm these findings and assess safety.
