🔬 The role of CoQ10 and PQQ in mitochondrial biogenesis: new cellular "power stations"
How to support energy and create new mitochondria
Mitochondria are the "power stations" of cells where ATP is produced. Their health determines energy levels and the function of the brain, heart and muscles. Two substances are especially important for mitochondria: coenzyme Q10, which participates in energy production, and PQQ (pyrroloquinoline quinone), studied as a stimulator of new mitochondria biogenesis.
What are mitochondria
Mitochondria convert nutrients into energy via the Krebs cycle and the respiratory chain. For more on the mechanism — see "Krebs cycle and cellular respiration".
With age and stress, mitochondria are damaged, which is linked to fatigue and aging. More — in "Mitochondrial dysfunction".
Coenzyme Q10
Coenzyme Q10 (ubiquinone) is a fat-soluble substance that carries electrons in the mitochondrial respiratory chain. It participates in ATP production and acts as an antioxidant in membranes.
What is PQQ
PQQ (pyrroloquinoline quinone) is a compound found in small amounts in food (kiwi, spinach, parsley, soy). PQQ is studied as:
- An antioxidant protecting mitochondria.
- A stimulator of mitochondrial biogenesis.
- Support for cognitive function.
Mitochondrial biogenesis
Mitochondrial biogenesis is the process of creating new mitochondria in cells. It matters for replenishing "power stations" after exercise and stress. Stimulators of biogenesis:
- Physical activity.
- Cold exposure.
- PQQ and some other compounds.
The combination of CoQ10 (support of existing mitochondria) and PQQ (stimulation of new ones) is often viewed as a synergistic strategy for energy.
Practice of use
| Substance | Typical dose | Goal |
|---|---|---|
| Coenzyme Q10 | 100–300 mg a day | Energy, heart |
| PQQ | 10–20 mg a day | Mitochondrial biogenesis |
What are mitochondria?
Organelles-"power stations" of cells where ATP, the main energy molecule, is produced.
Why is coenzyme Q10 needed?
It carries electrons in the respiratory chain, participates in ATP production and protects membranes as an antioxidant.
What is PQQ?
Pyrroloquinoline quinone — a compound studied as a stimulator of mitochondrial biogenesis and an antioxidant.
What is mitochondrial biogenesis?
It is the creation of new mitochondria in cells, important for replenishing energy resources.
Can CoQ10 and PQQ be combined?
Yes, they are often combined: CoQ10 supports existing mitochondria, PQQ stimulates new ones.
What is the CoQ10 dose?
Usually 100–300 mg a day; with cardiovascular disease — as agreed with a doctor.
What is the PQQ dose?
Studies use about 10–20 mg a day.
Where is PQQ found in food?
In kiwi, spinach, parsley, soy and fermented foods, but in small amounts.
Does CoQ10 help fatigue?
Some research links CoQ10 to improved energy, but the effect depends on the cause of fatigue.
What matters most for mitochondrial health?
Physical activity, proper sleep and balanced nutrition; supplements are additional support.
