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

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

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

Potential side effects include: Generally well-tolerated, Mild headache (rare), Mild gastrointestinal discomfort (rare).

What is PQQ and how may it relate to cardiovascular health?

Pyrroloquinoline quinone (PQQ) is a compound involved in mitochondrial biogenesis and antioxidant defense. Preliminary research suggests PQQ may support mitochondrial function in cardiac cells and reduce markers of inflammation and oxidative stress. Human clinical evidence for cardiovascular outcomes is still in early stages.

What dosage of PQQ has been studied in clinical trials?

Limited human studies have used 10–20 mg of PQQ per day. Most research on cardiovascular effects comes from animal and cell culture studies. Human trials have primarily measured inflammatory markers and mitochondrial function biomarkers rather than cardiovascular endpoints. More research is needed.

What are the potential side effects of PQQ supplements?

PQQ is generally well tolerated at studied doses of 10–20 mg daily. Headache, drowsiness, and mild fatigue have been reported rarely. Long-term safety data in humans is limited. There is insufficient data on interactions with cardiovascular medications. Consult a healthcare provider before use.

About

PQQ is a redox cofactor that stimulates mitochondrial biogenesis and acts as an exceptionally potent antioxidant (5,000 catalytic cycles vs. 4 for vitamin C). A small RCT found PQQ at 20 mg/day significantly reduced LDL cholesterol and CRP, but larger cardiovascular-specific human trials are needed.

How It Works

Redox cofactor that stimulates mitochondrial biogenesis through PGC-1alpha/SIRT1/AMPK signaling pathways; acts as an exceptionally potent antioxidant protecting mitochondrial membranes and reducing oxidative stress-induced endothelial damage; supports NAD+ synthesis indirectly by enhancing cellular energy metabolism; modulates NF-kB reducing vascular inflammation.
