Question 1

What is a mitochondrion and what is its role?

Accepted Answer

The mitochondrion is the organelle present in our cells responsible for producing energy in the form of ATP. It is often nicknamed the cell’s power plant. Its proper functioning depends on many cofactor nutrients, including several B-group vitamins and minerals that contribute to a normal energy-yielding metabolism.

Question 2

Which nutrients support mitochondrial function?

Accepted Answer

The B-group vitamins (notably B2, B3, B12), magnesium and iron contribute to a normal energy-yielding metabolism. Coenzyme Q10, in the form of ubiquinol, is involved in the cellular energy-production chain and is the subject of studies, without any health claim being authorised in Europe to date.

Question 3

Is CoQ10 useful for cellular energy?

Accepted Answer

Coenzyme Q10 is naturally present in the mitochondria and takes part in energy production. Its synthesis by the body tends to decrease with age. Studies document its interest, but no health claim is officially authorised. A supplement can therefore be considered as support, without any therapeutic promise.

Question 4

Does mitochondrial health decline with age?

Accepted Answer

Research suggests that mitochondrial efficiency can change with age and lifestyle. Regular physical activity, especially endurance, is one of the best-documented levers for supporting mitochondrial function. A diet rich in micronutrients complements this approach, with a supplement coming as support if necessary.

Question 5

How should I take a supplement for mitochondrial health?

Accepted Answer

B vitamins and magnesium are generally taken with a meal. Ubiquinol, being fat-soluble, is better absorbed with a meal containing a little fat. Follow the dosage of each product and seek advice from a healthcare professional, particularly in the case of treatment, notably anticoagulants.
