Feeling Fatigued?
Feeling Fatigued?
Mitochondria and Fatigue! Probably not something you immediately think of when you are feeling tired.
Often the first thing people think of when feeling fatigued, is that they are low in iron. But unless you have a blood test to confirm this, I always caution against supplementing. If you take iron and don’t need it, it can increase your levels of inflammation.
Being fatigued can be associated with your body not producing enough energy. You have a little pocket rocket inside all your cells called the Mitochondria. This is where your energy cycle happens. Our energy production takes place inside the mitochondria, where it produces a product called ATP. ATP is your energy currency and is needed for most metabolic reactions, including muscle movement.
You can think of the Mitochondria like a cell phone, in that it needs recharging all the time. And like a phone, as we age the battery function diminishes. Ageing alone decreases our ability to produce ATP (our energy enzyme) which happens in the mitochondria, and by the time we are 30 our production drops by 10% for every decade.
This is called Mitochondria Dysfunction, which is different to Mitochondrial Disease. Mitochondrial Disease is when the energy production cycle no longer works, and this is often a rare genetic condition. Mitochondrial Dysfunction is when the ability to produce energy has been impaired ie: the battery needs a charge.
There are over 300 conditions that are associated with mitochondria dysfunction, and some of those involve the following:
Chronic Fatigue Syndrome
Fatty Liver Conditions
Neurocognitive decline
Neurobehavioral and psychiatric diseases, such as autism spectrum disorders, schizophrenia, bipolar and mood disorders
Neurodegeneration such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease.
Cardiovascular disease
Autoimmune diseases, such as multiple sclerosis, systemic lupus erythematosus
Thyroid Conditions
Viral Susceptibility (Immune function)
Type 2 Diabetes
Cancer
As you can see there are many conditions associated with the Mitochondria. But what can you do to help?
One of the main nutrients our mitochondria need to produce energy is a product called Niacin also known as NAD-Nicotinamide or vitamin B3. If we are deficient in this nutrient the body will sequester large amounts of tryptophan to make tiny amounts of Niacin, and then hello to mood and sleep disorders on top of no energy!
There are also some common medications that can impact on the Niacin production, and they include:
Metformin (common for diabetes)
Anti-depressants
Anxiety Medications
Anaesthetics
Chemo drugs
Statins (reduce Co-Q10 production)
As well as Niacin, some other nutrients often used to help with ATP production are CoQ10, Lipoic Acid and L-Carnitine. CoQ10 is more essential for anyone on cholesterol lowering medications (Statins).
Mitochondrial dysfunction is directly related to fatigue, and therefore I don’t always go for iron when assessing this in my clients. But nor would I run out and buy any of the supplements I have mentioned. You need a proper assessment and quality supplements to have impact along with assessing why your energy production is not optimal.
You can make some changes via diet though to help ensure you have plenty of specific nutrients for production. Some specific foods relate to:
Niacin (B3) – Almonds, beef, chicken, eggs, fish, legumes, LIVER, peanuts, salmon, sunflower seeds
Lipoic Acid – Broccoli, brussel sprouts, peas, liver, potatoes, spinach and tomatoes
Co-Q10 - Eggs, fatty fish, organ meats, nuts and poultry
As you can see most of these foods are animal products so what about vegans? Nutritional Yeast is usually recommended as it contains the nine essential amino acids and is fortified with all the b vitamins.
So, if you are suffering with fatigue and iron is not the culprit you may need to consider your Mitochondria! Thyroid function and Long Covid are also other considerations, but both of these impact on your mitochondrial production also.
