Coenzyme Q10 (CoQ10)

Coenzyme Q10 (Ubiquinone) – it is a vitamin-like substance that plays a key role in the production of energy (ATP) in the mitochondria and the protection of cells from oxidative stress.

Main functions:

  1. Energy metabolism -participates in the respiratory chain of mitochondria, helping to synthesize ATP (especially important for the heart, brain, and muscles).
  2. Antioxidant protection -neutralizes free radicals, prevents cell damage.
  3. Heart support -improves myocardial contractility, reduces the risk of atherosclerosis.
  4. Slowing down aging – CoQ10 levels decrease with age.
  5. Immune system -increases the activity of phagocytes.

Symptoms of CoQ10 deficiency

A deficit occurs when:

  • Over the age of 40 (natural decrease in synthesis).
  • Taking statins (cholesterol-lowering drugs block CoQ10 synthesis).
  • Chronic diseases (heart failure, diabetes, Parkinson’s disease).

Signs of a shortage:
Chronic fatigue, weakness.
Muscle achesand cramps (especially when taking statins).
Shortnessof breath, arrhythmia (due to decreased energy in the heart muscle).
Memory loss, cognitive impairment.
High blood pressure.


Symptoms of excess CoQ10

Overdose is extremely rare, as CoQ10 is non-toxic. Possible effects when taking large doses (>300 mg / day):

  • Nausea, diarrhea.
  • Headache, insomnia.
  • Decreased appetite.

Note: A natural excess is not possible – the excess is excreted in the bile.


CoQ10 standards in analyses

CoQ10 levels are measured in blood plasma or lymphocytes (a more accurate method).

ParameterStandardOptimal level
Blood plasma0.5-1.5 mcg / ml>1.0 mcg / ml
Lymphocytes30-150 nmol / mg of protein>50 nmol / mg

When is the test scheduled?

  • With muscle weakness while taking statins.
  • For heart failure, migraines.
  • To assess the antioxidant status.

How to increase CoQ10?

  1. Food:
  • Fatty fish (herring, sardines).
  • Beef, chicken heart.
  • Nuts, seeds, spinach.
  1. Supplements (as directed by your doctor):
  • Ubiquinone (the usual form) – 100-200 mg / day.
  • Ubiquinol (reduced form– – better absorbed, especially after 40 years.
  1. Reducing risk factors:
  • Quitting smoking (accelerates oxidative stress).
  • Blood sugar control (diabetes lowers CoQ10).

Conclusion

CoQ10 is a vital component for energy and antioxidant protection.
Deficiency is manifested by fatigue, muscle weakness, and heart problems.
, Blood norm: 0.5-1.5 mcg / ml (plasma), > 50 nmol / mg (lymphocytes).
Supplements are effective for proven deficiencies or statin use.

Example: If the CoQ10 level is < 0.5 mcg / ml, it is recommended to take 100-200 mg/day in the form of ubiquinol.
