The reason your flares never fully stop has a name your rheumatologist never tested for.
By Dr. Christine·Mitochondrial Function, Researcher 22 years·14-min read
After countless years researching fibromyalgia and fatigue I can tell you the reason your flares never fully stop has a name your rheumatologist never tested for. It is an enzyme called CD38. Once you understand what it does, every failed treatment in your history starts to make sense.
The short version
- Fibromyalgia flares keep coming back because an enzyme — CD38 — destroys NAD+, the molecule your cells need to switch inflammation off. No standard panel measures it, which is why your labs read "normal."
- Single fixes failed because the loop has two ends. You have to restore NAD+ and block CD38 at once. Plain NMN does only half.
- Inner Heal does both — 1,000mg NMN plus the CD38 blockers quercetin and apigenin, in a 10-in-1 formula built for women over 45.
- Backed by a 100-day money-back guarantee, because a loop that ran for years does not close in 30 days.
Is this you?
Read these slowly. They are taken word-for-word from women living it.
- You sleep nine or ten hours and wake like you never slept at all.
- You pay for every good day — usually for three.
- You lose the word mid-sentence. You know it is there, it is just misfiled.
- Every test comes back "normal" while your body feels broken.
- You have a cupboard full of supplements and no idea if any of them work.
- Some mornings it feels like being hit by a truck before your feet touch the floor.
If you recognised three or more, the next four minutes are written for you.
I am a cellular health researcher. I specialise in mitochondrial function and chronic fatigue conditions, and I have reviewed data from more than 13,000 fibromyalgia cases. The overwhelming majority are women. So let me say the first thing plainly, because no one said it to you: you are not imagining this, and you are not exaggerating. The pain is real. The exhaustion is real. The fog is real. What is missing is not your effort. It is an explanation.
For years, every doctor you have seen has treated your inflammation like a fire. Spray water on the flames. Dampen the smoke. Prescribe something to make the burning feel further away. And for a few weeks, sometimes, it does. Then the fire comes back, exactly where it was, and you are told to try the next thing.
No one has asked the question that actually matters. Why won't the fire go out?
Your body has its own fire crew. Every cell carries one. Their job is not only to fight inflammation but to finish it — to resolve it, clear the scene, and rebuild what burned. That crew runs on a single fuel. A molecule called NAD+. Without it, the trucks roll out but the hoses run dry. The fire is never truly put out. It just smoulders, waiting to flare the moment you do something normal, like see a friend or carry the shopping. this was the part no one told me →
The thing draining the trucks is CD38. It is an enzyme whose entire job is to consume NAD+, and under the chronic inflammation every woman with fibromyalgia carries, it goes into overdrive. Published research shows CD38 activity rises so sharply with persistent inflammation that it becomes the primary driver of NAD+ decline — outpacing aging itself. No rheumatologist is testing for it. No GP has ever mentioned it. Your labs come back normal because no standard panel measures the thing that is actually wrong.
NAD+ is the fuel. CD38 is what's burning it.
There is one more piece, and it explains why this so often arrives or explodes in your forties. For most of your life, estrogen quietly suppressed CD38 — a brake on the enzyme you never knew you had. As estrogen falls through your late thirties and forties, that brake comes off, and CD38 runs unchecked on top of the inflammation already there. Two drains, where men have one. It is a cellular reason women hurt more, and get believed less.
This is the cycle your specialist never drew on a whiteboard. It is a closed loop, and it has been deepening quietly for years.
The loop, in six steps
- Chronic inflammation runs in the background.
- That inflammation activates CD38.
- CD38 destroys your NAD+ faster than the body can replace it.
- Without NAD+, your cells can't make energy or finish resolving the inflammation.
- You wake unrepaired — exhausted, foggy, inflamed.
- The exhaustion deepens the dysfunction.
What women said when they first read this
twelve years. twelve years of being told my bloods were fine and it was probably stress. this is the first time the whole thing has actually made sense. i had to read it twice.
same. the bit about the fire and the trucks running dry. that is exactly it.
i have taken NMN before and felt nothing so i nearly scrolled past. then i got to the part about why it does nothing on its own. well. that explains the $80 i wasted.
my 80 yr old mum has more energy than me and im 51. i dont know whether to cry or feel relieved that theres a reason.
Jenny, relieved is allowed. A reason is not a cure, but it is the thing most women here were never given. Be gentle with yourself this week.
Why everything you tried "did nothing"
Not because you chose badly. Because each one addressed one end of the loop, or none of it. Here is the autopsy.
✕ Turmeric & curcumin
It tamps down one inflammatory signal at the surface. Meanwhile CD38 keeps burning the fuel your cells need to put the fire out for good. The smoke fades; the fire keeps smouldering.
✕ Magnesium
One of the first things women try for tension, cramps, and sleep. It can help at the margins. It does nothing about the NAD+ being drained underneath. The muscles ease; the cellular drain keeps running.
✕ AIP & anti-inflammatory diets
Two years without gluten, dairy, sugar, alcohol — and most of your social life. You removed the external triggers. The internal loop kept running, because the drain was never on your plate.
✕ Meds from your doctor
They sedate and modulate pain signalling. They trade the pain for fog, and leave you functional for part of the day at best. The loop runs underneath the medication, untouched.
✕ NMN on its own
This one is the cruellest. Plain NMN does raise NAD+. But with CD38 in overdrive, the enzyme siphons the new fuel within days. You poured it in; the hole drained it out. A bucket with a hole in the bottom.
✕ NSAIDs & fish oil
They blunt a single inflammatory route for a few hours. They neither restore NAD+ nor stop CD38. The moment they wear off, the loop is exactly where it was.
One woman wrote to me that she had spent close to fourteen thousand dollars across six years. Her labs were still "normal." She was not careless. She was sold half-solutions, one at a time, by an industry that cannot profit from telling you the loop has two ends.
The only way out is to do two things at once
You cannot break a two-ended loop from one end. To stop it, you have to refuel the trucks and shut off the siphon — at the same time. Do one without the other and it fails.
Restore the NAD+
NMN is a direct precursor to NAD+. A clinically-meaningful 500mg dose refills the fuel the fire crew runs on — energy, repair, and the resolution of inflammation.
Inhibit the CD38
Quercetin and apigenin are natural CD38 inhibitors. They plug the hole, reinstating the brake estrogen used to provide — so the NAD+ you add actually stays.
Refill
500mg NMN rebuilds the NAD+ supply.
Protect
Quercetin + apigenin block the CD38 drain.
Resolve
Cells finally finish switching inflammation off.
Two keys, one lock. Refuel, and stop the drain. The simplicity is the point: it is the one combination the loop is vulnerable to, and the one combination almost nobody sells, because it cannot be sold a single bottle at a time.
Ten compounds. Two jobs.
Refuelling and protecting are not two ingredients — they are a system. This is the formula I was looking for and could not find, so it was built: a 10-in-1 stack of NMN plus nine synergists, dosed for women over 45.
What the first 90 days tend to look like
I have no interest in hype, so I will be careful here. A loop that has run for years does not close in a week. But there is a pattern in the messages I receive, and it tends to go like this.
The mornings, before anything else
The first sign is rarely energy. It is the absence of the crushing heaviness when you wake. Not a jolt — just a morning that does not feel like being hit by a truck.
The flares get shorter
The crashes do not vanish, but they soften and pass sooner. The 2am wake-ups get rarer. Small windows appear where you feel, briefly, like yourself.
The exhaustion itself begins to lift
This is usually the turn. With enough NAD+ to finish its repair work, the body starts resolving inflammation instead of carrying it.
Good days stop costing three bad ones
The loop loses its momentum. You stop rationing energy like money. The version of you that makes plans — and keeps them — starts coming back.

My bread test
For years a sandwich meant two days in bed. At week seven I ate bread at my daughter's birthday and waited for the punishment. It never came. I call it my bread test now.
Linda M., 46 · VerifiedIt wasn't dementia
I was 39 and quietly terrified I had early dementia — I kept losing words mid-sentence in meetings. Week five I got through a whole presentation without the fog dropping. It was cellular, not my mind.
My GP asked what I'd changed
My C-reactive protein had sat stubbornly high for years. By my next test, twelve weeks in, it had come down into range. My GP asked what I had changed. For once I had an answer.
Margaret H., 52 · VerifiedThe 2am waking stopped
Out like a light, then wide awake at 2am every single night for a decade. Around week five it just... stopped happening every night. I keep waiting for it to come back. It hasn't.
Robyn T., 58 · VerifiedSlower for me, but real
I will be honest, I noticed nothing for nearly six weeks and almost gave up. Then the afternoons changed. I am not cured. But I am not crashing at 3pm anymore. Giving it the full three months.
I stopped rationing my energy
I used to plan my whole week around one outing. This morning I did the shops and still made dinner. Small to anyone else. Not small to me.
Sandra J., 54 · VerifiedI have my afternoons back
I used to disappear by 2pm every day. My grandchildren only ever knew a tired grandma. Now I am the one suggesting the park. Twelve weeks in.
Mei L., 68 · VerifiedAt 72, I had made my peace with it
I assumed this was simply age, and I had stopped expecting anything else. I was wrong. The heaviness has lifted in a way age does not explain. I only wish I had known about CD38 years ago.
Beryl A., 72 · VerifiedReal women. Real kitchens.
day 34 — i look tired but i finally feel awake
60, and got my mornings back
day one. fingers crossed
first proper catch-up in months
back in my garden again
i have my afternoons back
ordered the 3 month for my sister and one for me. she has had fibro since her 40s and i am the "always tired, bloods fine" one. felt like this was written about both of us.
week 6 update since people asked. went for a walk yesterday and didnt pay for it today. that is the bit i cant explain to people who arent sick. you just dont pay for it.
"you dont pay for it" made me tear up. that is the dream.
The formula I couldn't find, so we built it: Inner Heal
500mg NMN plus nine synergists, in 60 vegetarian capsules — two a day. It does the two things the loop is vulnerable to, together: refuel the NAD+, and block the CD38 draining it. Built and dosed for women over 45.
Most women start with the 3-month reset — a loop that has run for years does not close in 30 days. So that is the offer I want to make easy today.

Honest answers to fair questions
I've wasted money on things that didn't work. Why would this be different?
Because everything you tried addressed one end of the loop, or none of it. This is built to restore NAD+ and block CD38 at the same time — which is the specific reason single fixes failed. It is not a better version of what you tried. It is the part that was missing from all of it.
How long until I'd notice anything?
Most women describe the first change between weeks two and four, and it is usually subtle — lighter mornings before anything dramatic. The deeper shift in energy tends to come around weeks six to twelve, as NAD+ rebuilds. That slow build is exactly why there is a full year to decide.
Is this just expensive NMN?
No, and that distinction is the whole point. Plain NMN refuels the trucks, then CD38 drains the fuel within days — a bucket with a hole in it. Inner Heal adds the two CD38 inhibitors that plug the hole, plus the antioxidant shield that protects the system while it rebuilds.
I take other medications. Is that a problem?
Inner Heal is a dietary supplement, not a drug. But if you take prescription medication, it is always sensible to run any new supplement past your doctor or pharmacist first — particularly in this age group, where several prescriptions are common.
What if it doesn't work for me?
Then you pay nothing. There is a 100-day money-back guarantee, because a loop that has run for years does not close in 30 days, and you should not have to gamble to find out. Give it a real trial. If your mornings have not changed, you get every cent back.
