Nobody Checks On The Person Doing The Checking

I have taken observations on roughly forty people a day for eleven years. My own last blood test was in 2021, and when I finally did one, two lines on it were flagged. Here is the part that actually surprised me: the reason every routine I had ever tried fell apart was not willpower. It was that my mornings move.

Four on, three off. Two lates, two nights, a sleep day that is not really a day, then the long shift that everyone pretends is twelve hours.

Half past three in the morning. Everybody else on the ward is someone I am responsible for.

If you work a rota you already know what I am about to say and you can skip this paragraph. If you do not, the thing to understand is this: I do not have a morning. I have four different versions of one, and which version I get depends on a spreadsheet published six weeks in advance.

Every single piece of health advice I have ever been given assumes I have a morning.

“Take it with breakfast.” Which breakfast? The one at 6am, the one at 4pm, or the one at half past midnight in a staff room with the lights off?

The Thing I Kept Calling Tiredness

For about two years I had been describing the same set of things to myself and filing all of them under the job.

A wall that arrived at the same point of every shift regardless of how I had slept beforehand. Losing words mid-handover. Walking into the store room and standing there. Bloating after meals that had been normal for so long I had stopped registering it. Weight collecting around the middle while nothing else changed.

Every one of those has a perfectly reasonable shift-work explanation, and I gave it one. Circadian disruption is real and I am not going to pretend otherwise.

But here is what made me look further. Six of us on the same rota, doing the same nights, eating the same terrible staff room food. Three of them were fine.

The Two Lines

I did a full panel in March, mostly because a colleague nagged me about it and I was tired of being the person who tells everyone else to get checked.

Thyroid normal. Ferritin normal. Vitamin D low, which I expected, because I had not seen daylight since November. B12 fine.

ALT 59. AST 44. Both marked high. The note in the record read mildly elevated — monitor, and I know exactly what that note means because I have typed it myself.

It means there is nothing to prescribe, the appointment is twelve minutes long, and this is genuinely not the most urgent thing in the room.

It does not mean nothing is happening.

Why A Tired Liver Feels Exactly Like Shift Fatigue

People picture the liver as a filter and stop there. It also manages blood sugar between meals, processes hormones, handles medication, and clears the by-products of your own metabolism out of circulation. Several hundred jobs, continuously, with no backup organ.

When it falls behind, the result is not a liver symptom. It is an energy symptom — fog, a wall, sleep that does not restore, bloating, weight round the middle. Which, if you work nights, you will attribute to the nights. Every time. For years.

The organ does its cleaning and repair using glutathione, and it does not keep much in reserve — it manufactures it continuously from a compound called NAC. Irregular eating, broken sleep, caffeine load and years of low-grade inflammation draw that supply down faster than it gets rebuilt, and nothing in an ordinary diet restores it directly.

NAC is what goes into an IV when a liver is in acute trouble. You will have hung one. That is the sentence that made me take this seriously, and if you work clinically it will land the same way for you — if that is what the organ runs on in a crisis, it is what the organ runs on generally.

Three more inputs matter for the same reason. Choline builds the packaging fat needs in order to leave liver tissue — without it the fat stays put no matter how well you eat. Dandelion and artichoke support bile, which is the route waste actually exits by. Milk thistle protects the cells while the other three catch up. Cover one and the other three carry on unattended.

The Real Reason Every Routine I Tried Died

I have bought things before. A multivitamin, twice. A B-complex someone recommended. A tub of something green.

Every one of them died in the same place, and it was not the third week, and it was not motivation.

It was the switch from days to nights.

Six weeks published in advance. Find me the fixed morning on it.
A routine anchored to “morning” cannot survive a rota. Four days into a night block, morning does not exist, and the habit has nothing to attach to.

This is well understood in behaviour research and almost never applied to supplements: habits attach to cues, and a cue that moves is not a cue. “With breakfast” is not an instruction if breakfast is at half past midnight on Thursday and 6am on Monday.

So when I looked again, I stopped asking which formula was best and started asking a much more boring question: which one of these can I actually take on a night shift, in a staff room, with cold hands, in ninety seconds?

What I Was Looking For

My criteria, in order

  • It has to attach to a cue that travels with me, not to a time of day. Mine is the first hot drink of a shift. That happens on every shift, at whatever hour the shift starts.
  • It cannot need food. Anything that says “take with a meal” is asking me to plan a meal I do not control.
  • It cannot be a tablet I have to swallow standing up in a corridor. Ten seconds, no water hunt, nothing to gag on.
  • It has to fit in a tunic pocket or a bag without leaking. Non-negotiable.
  • It has to cover all four jobs, because I am not running four bottles. I know myself.

What I Take Now

Nordvia Complete Liver Support. Seven actives in a liquid — NAC and L-Glutathione to rebuild, choline to move fat out of the tissue, dandelion and artichoke to drain, milk thistle to protect. Every amount printed on the panel.

The line is still running. What it has run short of is what goes into it.

Two millilitres from a dropper. Roughly ten seconds. No water needed, nothing to swallow, no food required.

Ten seconds, standing up, whatever hour the shift starts.

I take it with the first hot drink of whatever shift I am on. That cue has never once failed me, because there is no version of my working life that does not contain a first hot drink.

The bottle is 60 mL, which at 2 mL a day is thirty servings — a month exactly, so it runs on the same cycle as the rota rather than fighting it.

Over 500 jobs a day, zero support. One organ, no backup
The workload never changed. What changed is what it has to run on.
It is not a stimulant and it is not a caffeine replacement. Nothing in it borrows tomorrow’s energy to pay for today’s, which matters a great deal if you already finish a night block running on four coffees. You can take it alongside your coffee. Most people find they reach for the third one less.

What To Expect, Honestly

The honest calendar: nothing works in a week, not ours. 90 days is three bottles
Nothing works in a week. If a bottle promises you a week, put it down.
Weeks 1–2Most people feel nothing. Glutathione is rebuilding before there is anything to notice. This is where people stop.
Weeks 3–4The wall is usually the first thing to move. Not a surge — an absence. It is not where you left it in the shift.
Weeks 5–8The window where re-running ALT and AST becomes worth the draw.
Week 8+Steady state. Livers repair slowly and nothing changes that.
Do this first, and you know it better than I do: get the baseline. ALT and AST sit on most standard panels already. Write down today’s numbers before you start anything, and in sixty days you are looking at evidence rather than a feeling. You would insist on this for a patient.

Why Three Bottles

One bottle is thirty days. The guarantee runs sixty.

Buy a single month and judge it at the end of the month, and you have arranged the only version of this where the guarantee expires after you have already run out. Three bottles is ninety days, which is roughly the interval a repeat panel is worth booking at anyway.

Frequently Asked

When do I take it if my shifts rotate?

Attach it to an event rather than a clock. The first hot drink of the shift works for most people because it happens on every shift at whatever hour. Consistency of cue matters more than time of day.

Does it need to be taken with food?

No. That is one of the main reasons it survives a rota when tablets do not.

I already drink a lot of coffee. Does it clash?

No. It contains no caffeine and no stimulants, and it is not trying to replace your coffee. You can take it in the coffee if that is easier — the taste is undetectable in it.

Will it fit in a tunic pocket?

It is a 60 mL dropper bottle. It fits, and the cap seals. If you would rather not carry it, leaving it beside the kettle at home works too — the point is that the cue is fixed, not the location.

My vitamin D was the low one. Should I deal with that instead?

Deal with that as well — it is the single most common deficiency in people who work nights and it is worth correcting. It is a different pathway from the two lines that were flagged, and correcting one does not address the other.

What if nothing changes?

Sixty days, send it back, empty bottles accepted, full refund. No forms.

It was not a discipline problem and it was not only the nights. It was a routine built on a cue I do not have, attached to a set of symptoms I had been professionally trained to explain away, sitting three rows below the numbers that got discussed.
