What is the recommended dosage for PQQ (Pyrroloquinoline Quinone)?

General: 10-20 mg/day; Cognitive Support: 20 mg/day

What are the side effects of PQQ (Pyrroloquinoline Quinone)?

Potential side effects include: Headache, Insomnia, Mild fatigue.

Pyrroloquinoline quinone (PQQ) is a redox cofactor found in small amounts in foods like kiwi, parsley, and natto. Research suggests PQQ may support mitochondrial biogenesis (the creation of new mitochondria) and protect neurons from oxidative damage, potentially supporting cognitive function.

What dosage of PQQ has been used in studies?

Human studies have used 10 mg to 20 mg of PQQ daily. Some research has combined PQQ with CoQ10 for potential synergistic effects on mitochondrial function. The evidence base for PQQ and cognition is still emerging. Consult your healthcare provider for dosing guidance.

What are the potential side effects of PQQ?

PQQ appears to be well tolerated at recommended doses in limited human studies. Mild side effects may include headache and fatigue. Long-term safety data is limited. Consult your healthcare provider before supplementing, especially if you are pregnant, nursing, or taking medications.

About

PQQ promotes mitochondrial biogenesis and is the only known dietary compound to do so. A double-blind trial found 21.5 mg/day improved memory, attention, and cognitive function in middle-aged to elderly populations after 12 weeks.

How It Works

Promotes mitochondrial biogenesis via PGC-1alpha activation; protects neurons from oxidative damage with potency 5,000x greater than vitamin C per molecule; supports nerve growth factor expression.
