Quick answer: Fatigue, brain fog and low stamina can reflect mitochondria that are not producing energy efficiently. Practical ways to recharge them include a nutrient-dense diet with quality protein (including organ meats for those who eat them), a daily fasting window, strength training, brief cold exposure, enough sleep and reducing toxin exposure, with targeted nutrients when needed.
Key takeaways
Fatigue, brain fog and low stamina can reflect mitochondria that are not producing energy efficiently.
Quality protein, a daily fasting window, strength training and brief cold exposure are practical habits the article highlights.
Targeted nutrients can add support when needed, and testing can sometimes clarify where to begin.
What mitochondrial dysfunction feels like
Mitochondrial dysfunction can feel like persistent fatigue and brain fog, with low exercise tolerance and slow recovery, and a sense of feeling worse with stress.
These symptoms have many causes, so they deserve evaluation. For the science, see mitochondrial health.
Food-first support
Food-first support starts with quality protein at every meal, plus organ meats such as liver and heart, if you eat them, for CoQ10, B vitamins and minerals. Colorful vegetables and berries add antioxidants, and healthy fats such as olive oil and fish round it out.
Lifestyle habits
Helpful habits include a daily fasting window to support autophagy, interval training to build new mitochondria, and strength training to build muscle. Brief cold exposure, if appropriate, and seven to nine hours of sleep also help.
It also helps to reduce toxins with filtered water, glass containers and clean personal care (see decreasing toxic exposures).
Targeted nutrients when needed
PQQ, CoQ10, magnesium and berberine are among the nutrients I may use, chosen individually. If you work with me, the products I use are in my Fullscript dispensary.
Is testing helpful?
Organic acids and oxidative stress markers can add insight in complex cases. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Mitochondria and healthy aging
Mitochondrial dysfunction is a central process of aging. When cells clear worn-out mitochondria and build new ones, energy production tends to stay efficient and oxidative stress is easier to keep in check.
When to see a naturopathic doctor
It may be time to see a naturopathic doctor if you have persistent fatigue or brain fog, or low stamina or slow recovery. The same is true if you want to know if mitochondria are part of the picture, or if you want a personalized energy plan.
See a medical provider promptly for fatigue with chest pain, shortness of breath or fainting.

Questions to bring to your clinician
These questions can help you get the most out of your next visit.
Could my fatigue be related to mitochondrial function, and which habits should I start with?
What would be a gentle starting point for mitochondria-friendly habits, given where I am right now?
Is there anything in my health history that would make mitochondria-friendly habits need extra care?
How would we know that mitochondria-friendly habits is helping me, and when should we check in?
Frequently asked questions
How can I improve my mitochondria naturally?
Exercise, a nutrient-dense diet, sleep and a daily fasting window are the foundations.
Are organ meats good for energy?
They are rich in nutrients that support mitochondria, such as CoQ10 and B vitamins.
Does cold exposure help mitochondria?
Cold exposure may stimulate mitochondrial activity in brown fat. Use caution if you have heart conditions.
What supplements support mitochondria?
CoQ10, PQQ, magnesium and NAD+ precursors are commonly used.
