The Mitochondrial Assessment
Understanding your energy at its source
Your cells have not broken. They have entered a protective state — and this is a guide to what the assessment measures, why cellular energy declines, and how it may be restored, gently, naturally, and in the right order.

Why this occurs
Energy that has powered down by design
Mitochondria do not usually fail outright. More often, they are deliberately reduced in activity — a response, not a breakdown.
Something places the system under strain — most often a virus, at times another infection, a toxin, or a prolonged period of stress. In response, the cells enter a protective, energy-conserving state.
The difficulty is that the cells may remain in this state long after the original strain has passed. The result is persistent fatigue, an absence of reserve, and a system that does not readily return to full function on its own.
The aim of treatment, therefore, is not to force the system. It is to remove whatever holds it in this protective state, to calm the internal environment, and to guide the cells gently back towards full activity.
Why so much is affected
When energy is scarce, the body must choose
Every system in the body runs on the energy mitochondria provide. When energy becomes scarce, the body is forced to ration it — sustaining the functions essential to survival, and quietly withdrawing support from what it can manage without for a time. This rationing is sometimes described as energy theft: one demand met at the expense of another.
It is for this reason that a difficulty which begins within the cell rarely stays there. As energy is drawn away, other systems begin to falter in turn, and the picture broadens well beyond fatigue alone.
Commonly affected
The immune system
Defence is costly in energy. It may become underactive, allowing infections to linger or reactivate, or overactive, tending towards inflammation, allergy, and sensitivity.
Commonly affected
The hormonal system
The glands that govern energy, mood, and metabolism depend upon cellular energy to do their work. Their output may fall, and the body's finely balanced signalling may drift.
Commonly affected
The adrenal and stress response
Under sustained strain, the systems that manage stress and steady the body may become dysregulated, leaving a person feeling depleted, and less able to recover from demand.
Commonly affected
The autonomic nervous system
The automatic control of heart rate, blood pressure, digestion, and temperature may become unsettled — giving rise to light-headedness, palpitations, and poor tolerance of standing or exertion.
Recognising this wider pattern matters, because it explains why so many seemingly unrelated symptoms so often appear together. Among the conditions and presentations in which reduced cellular energy is frequently recognised are:
Chronic fatigue and post-viral syndromes (including ME/CFS and long COVID); fibromyalgia and persistent widespread pain; disorders of the autonomic system, such as postural orthostatic tachycardia; adrenal and thyroid imbalance; recurrent or reactivated infection; unexplained brain fog and cognitive difficulty; sensitivity to medications, foods, or the environment; and a general decline in resilience, recovery, and vitality that ordinary investigation does not explain.
Reduced cellular energy is seldom the whole of any diagnosis, but it is very often a thread running quietly through it. Restoring energy, therefore, tends to lift far more than fatigue alone.
What is measured
A complete assessment of cellular energy
Each measurement examines a different aspect of how the body produces and protects its energy. Below is what each one means, and how each may be supported.
Energy output
Reserve capacity
Number of mitochondria
The signal to renew(PGC-1α)
The natural defence system(Nrf-2)
Oxidative strain
Choice of fuel
The underlying cause
The wider foundations
Energy does not stand alone
Cellular energy is never restored in isolation. It rests upon foundations, and if one is disturbed, the mitochondria are among the first to feel it. Levitas therefore looks to the whole terrain in which the cells live, favouring natural means wherever they will serve.
Foundation · One
Natural optimisation
Wherever possible, the body is supported through natural means — nutrition, movement within limits, sunlight, breath, and the sensible use of botanicals and nutrients — so that recovery is gentle and sustainable rather than forced.
Foundation · Two
Detoxification
The body must be able to clear what burdens it. Before anything is cleared or treated, the natural routes of elimination are opened and supported, so that nothing accumulates and no unnecessary strain is placed upon a system already low in energy.
Foundation · Three
Gut and liver
The gut and liver are the body's centres of processing and defence. A settled gut and a well-functioning liver reduce the internal load upon the cells, and are attended to early, as they influence almost everything that follows.
Foundation · Four
Circadian rhythm and sleep
The mitochondria repair and renew most deeply during rest. Restoring a natural daily rhythm and protecting the quality of sleep is one of the most powerful and natural means of allowing energy to return.
Foundation · Five
Hormonal balance
The body's hormones govern its energy, its resilience, and its capacity to recover. These are assessed and, where required, gently and carefully balanced, so that the wider system is able to support the cells rather than work against them.
Foundation · Six
The basics, confirmed first
Before any plan begins, the fundamentals are checked and settled. This ensures that every step that follows is safe, is built upon firm ground, and is suited precisely to the individual before us.
Assess yourself
A short self-assessment
The questionnaire below offers a simple indication of whether cellular energy may be worth investigating. It is a guide for reflection and conversation, not a diagnosis. Select each statement that applies to you.
Over the past three months, how often have the following been true?
This self-assessment is intended to support reflection and discussion with a clinician. It does not diagnose any condition.
How energy is restored
The Levitas approach — to support, rather than force
The guiding principle is to work with the body's protective state, not against it. Treatment proceeds in a deliberate order, each stage preparing the way for the next.
Confirm the basics
The fundamentals are checked and settled before anything begins — hormones, the essential blood markers, sleep, gut and liver — so that the plan which follows is safe, well-founded, and suited to the individual.
Pace and protect
Remaining within one's energy limits to prevent collapse, simplifying the existing regime, and beginning a single gentle antioxidant. Nothing else succeeds without this foundation in place.
Establish the trigger
Testing for the underlying driver that holds the cells in their protective state, most commonly a virus, and other infections where indicated. The cause is addressed, not merely the symptoms.
Detoxification, gut and liver
The natural routes of elimination are opened and supported, and the gut and liver are settled, so that the body may clear what burdens it without placing further strain upon a system already low in energy.
Immune support
Where a viral cause is confirmed, low-dose immune support helps the body regain control of the virus. Because it calms rather than forces, it avoids the setback that stronger measures may cause.
Cellular support, by natural means
Once the system is stable, a small and carefully chosen combination of nutrients and gentle infusions is introduced, one at a time, with the response to each observed before the next is added.
Sleep, circadian rhythm and hormones
The natural daily rhythm is restored, sleep is protected, and hormonal balance is confirmed and gently supported — the deeper foundations upon which lasting energy depends.
The screen is then repeated after approximately twelve weeks, providing clear and measurable evidence of recovery rather than a reliance on how one feels alone.
In summary
Everyone is a signature, defined by their own response to all they meet in life — in mind, in body, and in soul. No two people arrive at the same place by the same path, and so no two plans are ever the same. Because your energy is reduced rather than lost, it can be restored — gently, naturally, and in the order that is right for you.

This guide is intended to support understanding and discussion with a Levitas clinician. Every plan is bespoke, and individual investigations, treatments and timings are determined on a personal basis. This guide explains the pattern that the results describe and does not constitute a diagnosis in itself.
