Mitochondrial health is health at the cellular level, which is based on the health of your mitochondria. Mitochondria are responsible for energy production and play a key role in maintaining cell vital functions.
When your mitochondria are working properly, your body has enough strength for daily tasks: from physical activity to mental concentration. Mitochondrial health affects your endurance levels, mood, and overall well-being, and also helps slow down the aging process.
If mitochondria are damaged, it can lead to decreased energy, fatigue, weakened immunity, and an increased risk of disease.
What is a mitochondrion?A mitochondrion is a tiny, cylinder-shaped organelle. Mitochondria produce adenosine triphosphate (ATP) molecules, participate in many intracellular and extracellular processes, are sources of many bioactive substances, and are involved in the regulation of iron, calcium, and the immune and endocrine response. In addition, mitochondria play an important role in apoptosis (programmed cell death), which allows cells to renew themselves in a timely manner, keeping healthy, strong cells and removing "sick," "broken," or weakened ones.
Mitochondria are found in almost all cells of our body. There can be hundreds or even thousands of them in a single cell. The more energy a cell needs, the more mitochondria it contains. For example, there are more mitochondria in heart, muscle, and brain cells because these organs require a lot of energy to function. And in the muscle cells of athletes, there are 2-4 times more mitochondria than in the muscles of people who avoid training.
Why support mitochondrial health?When your mitochondria are functioning normally, you feel energetic, alert, and resilient—you have enough strength for everything. But over time, due to aging, stress, poor diet, or illness, mitochondria can become damaged or decrease their activity. This can lead to fatigue, decreased concentration, depression, and even chronic diseases.
Disruption of mitochondrial functioning and, above all, disruption of mitophagy and mitodynamics, affects the development of insulin resistance, obesity, type 2 diabetes, metabolic syndrome, and atherosclerosis.
How to support mitochondrial health?Maintaining mitochondrial health is the key to preserving energy, endurance, and overall well-being. Mitochondria are responsible for energy production in cells, and when they function correctly, we feel alert and energetic.
What helps support mitochondrial health:
- Proper nutrition plays a key role in this. Foods rich in antioxidants help protect mitochondria from damage, while healthy fats, such as omega-3s, support their membranes and improve performance. Vitamins, minerals, and proteins, such as magnesium, zinc, and B vitamins, are important for proper cellular metabolism and improving energy processes. Proper nutrition also helps reduce oxidative stress, which can damage mitochondria and accelerate aging.
- Physical activity helps mitochondria work more efficiently. When we challenge the body with manageable physical activity, especially aerobic exercise (running, swimming, walking), our cells begin to need more energy. This stimulates the mitochondria, making them work harder and even increasing their number in the cells. And the more mitochondria in the body, the higher our endurance and ability to recover. Regular workouts help mitochondria be more resistant to damage and improve their performance.
- Stress management is very important for mitochondrial health because chronic stress causes an excess of the hormone cortisol, which can negatively affect their performance. High stress levels contribute to mitochondrial damage and a decrease in their ability to produce energy. Relaxation methods—like meditation, deep breathing, or yoga—help lower cortisol levels in the body, protecting your mitochondria from destructive effects.
- Good sleep. During sleep, mitochondria recover and clear out toxins that accumulate throughout the day. Lack of sleep disrupts this process, which can lead to decreased mitochondrial efficiency and an overall drop in the body's energy. Sleep helps maintain normal mitochondrial function, improves their ability to produce energy, and protects them from damage. That's why regular, high-quality sleep is one of the key factors for maintaining mitochondrial health and improving your overall well-being.
- Calorie restriction and intermittent fasting. Research shows that reasonable, moderate calorie restriction (not starving yourself, but controlling the number of calories you consume) can stimulate mitochondrial activity and their ability to produce energy. Intermittent fasting also helps maintain mitochondrial health by activating the process of autophagy (cellular self-cleaning).
- Supplements for mitochondria
- Antioxidant supplements, alpha-lipoic acid help improve mitochondrial function by protecting them from damage.
- Polyprenols — are converted in the liver into dolichols. Dolichols play an important role in repairing damaged cell membranes, including mitochondrial membranes. Polyprenols also help improve energy production by mitochondria thanks to their powerful antioxidant properties.
- Zinc — helps activate antioxidant enzymes in mitochondria, protecting them from oxidative stress. It also supports normal immune system function and promotes the synthesis of proteins needed for cell repair.
- Lecithin — supports the health of all cell membranes, including those of mitochondria.
- Omega-3 fatty acids — help maintain the health of mitochondrial cell membranes, improving their ability to produce energy. Omega-3s also have antioxidant properties that protect cells from oxidative damage.
- Magnesium — is important for maintaining normal energy metabolism in cells and supporting mitochondrial function. It is involved in the production of ATP, which is the main source of energy for cells.
- L-carnitine — helps improve fat metabolism, which contributes to increasing the efficiency of mitochondria in energy production.
- Vitamin D — helps regulate cellular metabolism and improves mitochondrial function, increasing their ability to produce energy. It also supports the immune system and can reduce the risks of diseases associated with energy deficiency and fatigue.
