You Are Not the Exception

The pieces on this site describe deficiencies. Magnesium in roughly a third of the population. Potassium in nearly all of it. Vitamin D below the functional threshold in the majority of adults at temperate latitudes. Ferritin under thirty in about a third of menstruating women. Omega-3 Index below the target of eight in the great majority of Westerners. Folate masked by fortification. Functional B12 unmeasured. You read these numbers, and a quiet arithmetic happens somewhere at the back of your attention. Those people, you think. The ones being missed. The undertested. The unlucky.

It does not, quite, occur to you that you are one of them.

The math no one does out loud

Take the numbers this site documents. The probability that any single adult in an industrialised population is adequate on magnesium is around seventy percent by intake surveys; by tissue tests it is lower. On potassium (the four thousand seven hundred milligrams that international guidelines set as adequate), the probability of meeting the intake is under five percent. On vitamin D above the functional threshold most researchers now defend (roughly seventy-five nanomoles per litre, thirty nanograms per millilitre), the probability is under a third. On Omega-3 Index at or above eight, roughly one in ten Western adults. On ferritin above thirty micrograms per litre in a menstruating woman, about two out of three. On functional B12 with a normal methylmalonic acid past the age of fifty, well under nine in ten.

Multiplied (even generously, even were these independent events, which they are not), the probability of being adequate on all of them at once is under half a percent. And they are not independent. The exposures compound in the same direction: the person whose soil, whose refined grain, whose industrial oils, whose water, whose sun, whose stress load has depleted them on one has almost certainly been depleted on the others by the same mechanism. The correlation strengthens the arithmetic. It does not weaken it.

You are, by the ordinary mathematics of the population you belong to, almost certainly deficient in at least two of the nutrients this site names, and more likely in several.

“But I feel fine”

You feel fine in the sense that you are used to feeling. That is not the same as being physiologically adequate.

You do not know what your energy would be at ninety-five percent of ATP production because you have never operated at ninety-five percent of ATP production. You do not know what your sleep would be with sufficient magnesium and adequate iron because your sleep has always been the sleep of someone with insufficient magnesium and inadequate iron. You do not know what steady, unforced attention feels like on optimal B12, optimal ferritin, an Omega-3 Index at eight, and a vitamin D above the threshold at which the receptor is actually saturated. Those conditions have not once, in your adult life, been simultaneously true.

The comparative baseline against which you judge yourself well is a baseline shaped by the same depletion the rest of the population carries. The tired reader who says they feel fine is not lying. They are reporting accurately against a baseline that has never included the thing they would be comparing to.

Feeling fine, in an industrialised population in 2026, is not evidence of adequacy. It is evidence of adaptation.

“You can’t diagnose people online”

This is true, and this is not what this site is doing.

The medical rule that forbids diagnosis at a distance concerns the individual, named patient about whom the clinician has insufficient information. It is a rule against reckless certainty about a specific person. It is not, and has never been, a rule against publishing the population-level probability applicable to any reader who belongs to that population. The public health bulletin that reports half the adult population as vitamin D insufficient in winter is not diagnosing anyone. It is publishing the prior probability against which any individual assessment must then be interpreted.

What this site does, in its own mode, is publish the priors. The reader who applies them to themselves is doing the honest arithmetic: the same arithmetic a competent clinician would do if that reader walked into their consulting room. That clinician, faced with the reader in person, would order the tests set at the right thresholds and either confirm the prior or refute it. That the reader’s actual clinician will most likely not order those tests, or will read them at the wrong number, is the failure this site exists to name.

The false position is not to publish the priors. The false position is to withhold them: to allow the reader to imagine they are the exception, and to defer to a testing regime that has already declined to look.

The named prior

You, reading this, are almost certainly among the deficient in at least one of the nutrients this site documents, and more likely in several. This is not a diagnosis. It is a prior. It has the ethical force of every honest statement about the population you actually belong to.

You have the right to know it. You have the right to be tested against thresholds that reflect tissue function rather than the bottom of your local population’s distribution. And you have the right to be told, plainly, that the quiet assumption of adequacy (the certainty that the missed cases are the other ones) is the assumption this site is asking you to give up.

The pieces on this site are not written about someone else.
