You’ve in all probability heard the phrase, “The mitochondria are the powerhouse of the cell.” However what does that imply? Why do you have to care? I’m right here to clarify why our mitochondria perform are important to our well being and why we must always deal with them to extend longevity.
What Are Mitochondria?
Your physique is made up of trillions of cells that come collectively to make your tissues, organs, and extra. Particular organelles exist inside these cells to assist them do their job. One such organelle is the mitochondrion, which you’ll be able to consider as a bit of vitality manufacturing unit. That’s the place the time period “powerhouse” comes from — it’s fairly actually a home to make energy. The mitochondria produce 90% of the vitality utilized by our our bodies.
To supply this vitality, our mitochondria want gasoline. They use oxygen from the air we breathe and vitamins from the meals we eat to create adenosine triphosphate (ATP), our physique’s vitality foreign money. In different phrases, the carbohydrates, proteins, and dietary fat you eat are absorbed and transformed by the mitochondria into vitality. Your cells and tissues use that vitality to perform.
The varied tissues inside your physique have differing portions of mitochondria in every cell. The tissues that require essentially the most vitality to perform, resembling your coronary heart, liver, mind, muscle mass, and brown fats, comprise essentially the most mitochondria. For instance, an energetic muscle cell accommodates as much as 3000 mitochondria per cell. Sadly, mitochondria don’t perform optimally perpetually. Over time, they turn into dysfunctional, and this decline is a trademark of growing old1.

How Can I Preserve My Mitochondria Wholesome and Vibrant?
When mitochondria turn into too broken to provide vitality in the way in which we want them to, they start to interrupt down into fragments. To protect the vitality manufacturing course of and preserve general mitochondrial effectivity as excessive as attainable, our mitochondria then bear a recycling course of referred to as mitophagy. Mitophagy is a sort of autophagy, or a course of that permits our physique to reuse pointless mobile elements to rejuvenate itself. Throughout mitophagy, our our bodies filter these damaged mitochondria fragments and recycle them into contemporary mitochondria which are able to producing vitality effectively once more. This manufacturing of recent mitochondria is named mitochondrial biogenesis.
Sadly, mitophagy turns into much less environment friendly as we age and expertise stress from our environments. We accumulate extra mitochondrial particles and have general decrease vitality manufacturing. Fortunately, researchers have discovered three avenues to stimulate mitophagy.
This isn’t an alternative to skilled medical recommendation. See your major care doctor when making modifications to your way of life.
The Three Methods We Can Enhance Mitochondrial Operate Well being
1. Train
You already know that there are a lot of causes to interact in common train, together with advantages to your cardiovascular, pulmonary, psychological, and metabolic programs. However do you know that many of those advantages are literally on account of train bettering our mitochondrial perform?
For instance, endurance coaching induces mitochondrial biogenesis, which subsequently will increase mitochondrial density (extra mitochondria per gram of tissue) 2. Higher mitochondrial density means an enhanced capability to provide vitality. Along with selling mitochondrial biogenesis, train triggers mitophagy3 to take away the buildup of broken mitochondria, making area for the regeneration of higher-functioning organelles.
2. Food plan
The primary approach to promote mitophagy via food regimen is to make use of a technique referred to as intermittent fasting (IM) or time-restricted feeding (TRF). This requires specifying a window of time every day for fasting. Though the proof has been combined on the efficacy of IM/TRF for well being4, weight administration5, and athletic efficiency6, there’s overwhelming proof that means IM/TRF induces mitophagy7. This implies that IM/TRF could possibly be a useful technique to advertise longevity via your mitochondria.
Nevertheless, fasting just isn’t all the time acceptable or sustainable for everybody. Skilled athletes, for instance, have grueling schedules with excessive coaching masses that require a extra constant consumption of vitamins and energy to maintain up with vitality expenditure and promote restoration.
The second technique to enhance mitochondrial well being is to emphasise nutrient-dense vegatables and fruits in your day by day consuming habits. These are excessive in polyphenols, antioxidants, and different important vitamins that promote mitochondrial well being. They’re additionally low in saturated fat and added sugar, each of which may injury your mitochondria and be dangerous to your general well-being.
In fact, there will be points with diet-based methods. For most individuals, following a nutritious diet is a problem. Second is the difficulty of bioavailability, that means your physique’s capability to soak up the vitamins from the meals that you simply eat. For instance, the bioavailability of polyphenols has been proven to fluctuate tremendously8,9, so it’s attainable to eat a food regimen stuffed with polyphenols and antioxidants whereas solely absorbing a small fraction of these vitamins. In these circumstances, supplementation could also be mandatory.
3. Dietary supplements
Inside the final 20 years, there was a novel discovery in the case of optimizing mitochondrial well being: a nutrient derived from pomegranates referred to as Urolithin A (UA). UA is useful for mitochondrial well being as a result of, like train and intermittent fasting, it stimulates mitophagy10,11.
UA is a postbiotic, that means your intestine microbiome naturally produces it once you eat its precursor meals. These precursor meals embrace pomegranates, walnuts, and sure berries, that are all excessive in ellagitannins (a sort of polyphenol). Nevertheless, just like the aforementioned bioavailability difficulty, analysis has proven that solely about 30% of individuals have the suitable intestine microbiome to transform ellagitannins into UA12. And even amongst those that can produce UA, most don’t often eat sufficient of the precursor meals to see the advantages. This leaves supplementation as the most effective technique for many of us.
By way of mitophagy mechanisms, UA dietary supplements have been proven to enhance muscular power and endurance in each older13 and middle-aged14 adults. Moreover, there’s rising proof in pre-clinical fashions for its optimistic influence on cartilage degeneration15 and immunity16, in addition to mind well being17.
Prioritizing Mitochondrial Operate
Most of us don’t give a lot thought to our mitochondria, however they play an important position in our muscular well being and longevity. Anybody seeking to optimize their well being or efficiency ought to take into consideration how one can assist these energy-producing organelles. By using focused train, food regimen, and supplementation methods, you may preserve your mitochondria and muscle mass vigorous.
