Estimate a mitochondrial health and recovery capacity index from fatigue, sleep, exercise tolerance, and metabolic balance ratings.
Mitochondrial Health Index
Estimate a mitochondrial health index and recovery capacity score from simple energy and lifestyle ratings.
Input your energy and recovery profile
Formula
Mitochondrial health index blends inverse fatigue, exercise tolerance, sleep quality, and metabolic balance into a 0–100 score. Higher values suggest more robust energy production and recovery in everyday life.
Recovery capacity score focuses on sleep and fatigue to estimate how well you bounce back from daily stressors and activity.
The model is intentionally simple and educational; it is designed to prompt reflection and conversation with your care team, not to replace formal diagnostics or lab testing.
Steps
Rate your average daily fatigue on a 0–10 scale (0 = none, 10 = maximal exhaustion).
Rate your current exercise tolerance on a 0–10 scale (0 = cannot exercise, 10 = excellent capacity).
Rate your usual sleep quality on a 0–10 scale, considering depth, continuity, and refreshment.
Rate how “in-range” or optimized your key metabolic markers feel overall (labs + symptoms) on a 0–10 scale.
Review your mitochondrial health index, recovery capacity score, and targeted guidance.

Mitochondrial Health Index: A Practical, Patient-Friendly Guide to Everyday Energy
This guide explains why mitochondria matter, how everyday signals like fatigue and sleep can reflect cellular energy, and how to use this calculator as a conversation tool with your healthcare team.
Mitochondria are often described as the “power plants” of your cells because they generate most of the adenosine triphosphate (ATP) used for cellular work. They are especially dense in tissues with high energy demand: brain, heart, skeletal muscle, and liver. When mitochondrial networks are stressed, fragmented, or under-supported, people may notice symptoms like fatigue, exercise intolerance, brain fog, and slower recovery.
Clinical mitochondrial disease is rare and requires specialized evaluation, but milder mitochondrial dysfunction can show up across many chronic conditions, from metabolic syndrome to neurodegenerative disorders. This calculator does not attempt to diagnose those conditions—it simply organizes subjective signals that relate to energy and recovery.
2. Everyday Signals of Energy and Recovery
Four broad symptom domains provide accessible clues about mitochondrial health: fatigue, exercise tolerance, sleep quality, and metabolic balance. While nonspecific, these domains capture the lived experience of cellular energy output and repair capacity in daily life.
For example, people with relatively healthy mitochondrial function often describe steady daytime energy, predictable recovery from physical activity, and sleep that leaves them refreshed. In contrast, those with strained energy systems may report “energy crashes,” delayed-onset fatigue after exertion, or feeling wired but tired at night. Tracking these patterns over time can help clinicians decide when to investigate further.
3. Lab Markers and Objective Metrics that Inform Mitochondrial Health
No single lab test perfectly measures mitochondrial function, but several markers provide context. Blood sugar control, lipid profiles, iron studies, thyroid function, vitamin D, B12, and inflammatory markers all interact with energy metabolism. In some specialized settings, clinicians may also order lactate, pyruvate, organic acids, or genetic testing when indicated.
Wearables and home devices can add further insight: heart rate variability (HRV), resting heart rate, sleep staging estimates, and step counts create a picture of how your body responds to training and stress. The mitochondrial health index in this tool is deliberately simpler, but it can sit alongside those metrics as a human-readable summary of how you feel.
4. Lifestyle Inputs that Support or Strain Mitochondria
Mitochondria thrive when the environment is “challenging but manageable.” Too little stimulus (sedentary living) and too much unbuffered stress (overtraining, sleep deprivation, chronic inflammation) can both degrade function. The most impactful levers are usually fundamental: regular movement, strength training matched to your capacity, nutrient-dense meals, circadian-friendly light exposure, and structured stress management.
Over time, small, sustainable changes in these domains may shift mitochondrial health more than any single supplement. That is why this calculator emphasizes sleep, fatigue, and tolerance to activity rather than specific nutraceuticals. Once the basics are in place, you and your clinician can decide whether and how targeted supplements fit your picture.
5. How to Use This Index with Your Healthcare Team
If your scores are low or trending downward, consider scheduling a dedicated visit to explore drivers of fatigue and recovery problems. Bring logs of your sleep, exercise, and daily symptoms, along with any wearable data you track. This context can help your clinician prioritize tests and discuss treatment options.
Importantly, a higher mitochondrial health index does not mean you should ignore warning signs like chest pain, shortness of breath, rapid unintentional weight loss, or neurological changes. Always treat red-flag symptoms as urgent and seek medical care promptly, regardless of calculator scores.
Conclusion
Your day-to-day energy and recovery are multi-factorial, and mitochondria are one important part of that story. By scoring fatigue, exercise tolerance, sleep, and metabolic balance, this calculator gives you a structured way to track trends and open deeper conversations with your healthcare team. It is not a diagnostic, but a lens through which to view your health decisions over time.
FAQs
What is the Mitochondrial Health Index in this calculator?
It is an educational composite score built from self-ratings of fatigue, exercise tolerance, sleep quality, and metabolic markers. It is not a diagnostic test, but a structured way to reflect on cellular energy trends.
Can this tool diagnose mitochondrial disease or dysfunction?
No. Diagnosing mitochondrial disease requires specialized clinical evaluation, lab testing, and sometimes genetic workup. This tool is for self-reflection and education only.
How should I rate metabolic markers if I do not have recent labs?
Use your best estimate based on prior labs, clinician feedback, and symptoms like blood sugar swings, lipid issues, or blood pressure. For precise assessment, ask your clinician to review your current results.
Why are sleep and exercise tolerance included in a mitochondrial score?
Mitochondria affect energy production, recovery, and resilience. Sleep quality and exercise tolerance are practical, real-world signals that often track with underlying cellular energy health.
Can lifestyle changes improve mitochondrial health?
Emerging research suggests that movement, nutrient-dense foods, blood-sugar balance, stress management, and sleep support mitochondrial function. Always tailor interventions with your clinician.
How often should I repeat this assessment?
Many people check monthly while implementing new routines, then every 3–6 months as patterns stabilize. Use the same rating approach each time for better comparisons.
Does a low score mean my mitochondria are permanently damaged?
Not necessarily. A low score highlights that energy, recovery, or metabolic balance feel strained. It is a signal to investigate further, not a conclusion about irreversible damage.
Should I change or add supplements based on this score alone?
No. Supplement protocols for mitochondrial support (such as CoQ10, carnitine, or others) should be guided by a clinician who understands your diagnoses, medications, and labs.
How can I bring this information to my healthcare team?
You can share your scores, trends over time, and notes about fatigue, exercise tolerance, and sleep. This context can complement objective testing and help focus your visit.
Summary
This calculator estimates a mitochondrial health index and recovery capacity score using simple 0–10 self-ratings.
It surfaces patterns in fatigue, sleep, exercise tolerance, and metabolic balance to support more informed lifestyle and clinical decisions.
Always interpret scores in partnership with qualified healthcare professionals who can connect them to your full medical picture.
