Biochemistry and mechanisms of action

🔬 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.

Key: without CoQ10, mitochondria cannot efficiently produce energy. It is especially important in the heart — one of the most energy-demanding organs. On CoQ10 forms — see "Ubiquinone vs ubiquinol".

✨ 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.
Mechanism: PQQ activates factors linked to the growth of new mitochondria (e.g., via AMPK and PGC-1α). Data are mostly laboratory; effects in humans are being studied.

🌱 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

SubstanceTypical doseGoal
Coenzyme Q10100–300 mg a dayEnergy, heart
PQQ10–20 mg a dayMitochondrial biogenesis
Important: data on mitochondrial biogenesis in humans are still limited. The main "engine" is physical activity, and supplements are additional support. With cardiovascular disease, CoQ10 — as agreed with a doctor.
❓ Frequently asked questions
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.
