The Mitochondrial Assessment

Measuring your energy at its source

When fatigue persists and ordinary tests appear normal, the difficulty often lies not in any single organ, but deep within the cell in the mitochondria that produce the body’s energy. This assessment looks directly at how well they are working, building a complete picture of how much energy the body makes, whether it can rise to meet demand, and how well the cell is defended.

Simple · At home

A straightforward sample collection kit

The assessment begins with a simple blood sample, collected using the kit provided and returned to the laboratory. Everything required is included, with clear instructions at each step.

At a glance

What is examined

Energy output

How much energy the cells produce.

Reserve on demand

Whether output can rise when needed the defining measure.

Number of mitochondria

How many energy structures each cell holds.

The signal to renew

Whether the body is building new mitochondria.

Natural defences

How well the cell resists oxidative wear.

Fuel & flexibility

Which fuels are used, and how well the cell adapts.

Interpretation. A low-output, low-reserve, oxidatively-strained picture, in which the cells cannot raise their energy when asked to the pattern seen in post-viral and chronic-fatigue states. There is no active inflammation and no major structural damage: a system powered down protectively, and therefore well placed to recover.

Why so much is affected

How reduced energy radiates outward

When energy is scarce, the body must ration it which is why a difficulty beginning in the cell rarely stays there.

Assess yourself

A short self-assessment

A simple indication of whether your cellular energy may be worth investigating. It is a guide for reflection, not a diagnosis. Select each statement that applies to you.

Over the past three months, how often have the following been true?
I feel tired in a way that rest and sleep do not fully relieve.
After physical or mental effort, I feel noticeably worse for a day or more.
My energy runs out suddenly, rather than gradually.
I experience difficulty with concentration or memory, often described as brain fog.
My symptoms began after a viral illness, infection, or a period of significant stress.
I no longer tolerate exercise the way I once did.
I wake unrefreshed, regardless of how long I have slept.
My digestion is unsettled, or I feel my gut is not as it should be.
I am sensitive to supplements or medications, or react to small doses.
My capacity for a normal day has narrowed compared with a year or two ago.
