7 Things They Never Checked Before Writing 'Idiopathic' On Your File
He even jokingly said it's called “idiopathic” because they're idiots for not finding the cause of our condition.
mrmacabre, Mayo Clinic Connect
Jenny in the UK wrote the same thing. So did cax75, and u/zombiemann on Reddit. Three platforms, two countries, four people who have never met, all reading one word the same way.
Nobody told you there was no cause. They told you they hadn't found one.
Those are two different sentences. Only one of them is on your file.
Twenty tubes of blood. An EMG. Maybe a punch biopsy. Maybe four days at Mayo, like NJ Ed, who came home and wrote: “I figured if they can't figure it out, nobody will.”
Seven things, all in your house tonight
- The number on your B12 line
- What you take for your stomach
- The time on the clock when it starts
- Which form was in the bottle
- The dose you actually got
- What happens between your mouth and your foot
- What “it stopped getting worse” is worth
The exact number on your B12 line
Your report has a number on it, and a printed range beside it. You were told the word. You were probably never told the number.
One man on a UK forum came back at 260 pg/mL. Normal, they said. On Reddit, u/fehfaus: “Mine may have been due to b12 (270pg).” Normal, they said.
A 2024 study out of Turkey looked at people whose B12 was early and subclinical, not under the deficient line, and still found small fiber involvement that could be measured.
Open your patient portal. Find the B12 line. Write down the number and the range beside it.
We are not telling you that number is your cause. Nobody can tell you that from a web page. We are telling you that you should be the one holding it.
What you’ve taken for your stomach for fifteen years
Long-term acid reducers change how much B12 your gut pulls out of food. It never comes up in the ten minutes where the word idiopathic gets typed, because your reflux lives in another appointment, with another doctor, in another folder.
The man with the 260 had reflux since he was fifteen, and years of Nexium and Zantac behind him.
Open the cabinet. Read the box. Count the years. Then find the date on your bloodwork.
Nobody ever put those two pieces of paper on the same table. You can, in ninety seconds.
The time on the clock when it starts
Barnsbury, Bridielena and mikead63 describe the same window, independently, in three separate threads. Thirty to sixty minutes after lying down. Gone by morning.
Read that again, because it is the part that gets dismissed. A body doing something random does not run on a schedule. Yours does.
Notepad on the nightstand. Two numbers: the time you lie down, the time it starts.
Keep it. Two numbers tonight, the same two in ninety days. If the window hasn’t moved, you send the bottle back and you have lost the postage. Nobody selling a $9,600 program hands you a test that can fail in front of them.
Which form was in the bottle you gave up on
The label said B12. It never said which B12. Cyanocobalamin is the cheap form your body has to convert first. Methylcobalamin is already the form nerve tissue uses. Both are legally “B12” on a front label.
The bottle in the drawer, the one you gave a fair thirty days. Read the small print. Alpha lipoic acid, or R-alpha? Cyanocobalamin, or methylcobalamin?
You may not have failed the ingredient. You may never have taken the active half of it.
The dose you actually got, not the one on the box
“Proprietary blend, 500 mg” tells you the total. It never tells you your share of it. You can pay for eight ingredients and receive a rounding error of seven.
And one goes the other way. One man’s ordinary multivitamin carried 1208% DV of B6. He stopped it and wrote that the burning went away in a few days.
Your multivitamin. Not the nerve bottle, the ordinary one. Find the B6 line and the % DV beside it.
If you have spent three years quietly stacking B6 onto a nerve you were trying to protect, that fact is printed on a label in your kitchen. It is not in your file, and it is not your fault.
What happens between your mouth and your foot
Go back to point 2 for a second. Whatever you swallow has to clear your stomach first — and your stomach is the one organ here you have been adjusting, on prescription, for fifteen years.
That is not a diabetic argument. You don’t have diabetes and you have said so to every doctor who asked. It is a reflux argument, and reflux is the most ordinary thing in the world.
Stomach acid, then the gut wall, then the liver, which filters a share of whatever got that far. What arrives at a nerve ending in your foot is a fraction of what you paid for. That difference is printed nowhere, on any bottle, including ours.
Held under the tongue, there is no trip: into the bloodstream in 30 to 60 seconds, past the stomach and the liver entirely. Nitroglycerin is given that way in a cardiac emergency for exactly that reason.
Take your acid reducer box to the pharmacy counter. Ask: “Does this affect how I absorb B12 from a pill?”
Ninety seconds, from someone with your prescription history on screen and nothing to sell you.
What “it stopped getting worse” is actually worth
Nobody offered you that. You were offered a cure or nothing, and you stopped believing in cure around year three.
So look at what people in your position keep paying for. These are reviews of other brands, and we are not going to pretend otherwise:
That is the honest ceiling of this category, written by people who reorder anyway. Not a miracle. A line that stopped moving.
A pen. Mark where the numbness ends on your leg. Write today’s date beside it.
That mark costs nothing and it is worth more than the last three specialist visits, because in ninety days it answers the only question you have been asking: did it move?
The part where you are right
You are right, and here is how right.
The 2024 Cochrane review of alpha-lipoic acid pooled 3 trials and 816 participants and found little or no effect on symptoms. A 2026 review in Nutrients states that no trial has demonstrated nerve regeneration, and limits itself to diabetic populations. Not yours. Yours was excluded.
So the honest version: there is no trial that says this fixes idiopathic neuropathy. Anyone who tells you there is, is selling you something worse than a supplement.
What is not in dispute is smaller, and checkable. Which chemical form is active. What a printed milligram is. What route reaches the bloodstream without a stomach. Those are facts about a bottle, and you can verify every one before spending a dollar.
What it costs, and what to compare it to
Your own forums price the alternatives: $250 a session, $5,000 for a device, $9,600 for a program, $9,200 for Walkasins with insoles at $820 a year.
Per 2 mL dose, printed, nothing blended:
| R-Alpha Lipoic Acid | 2,400 mg |
| Methylcobalamin (active B12) | 4,000 mcg |
| Benfotiamine | 96 mg |
| Magnesium Glycinate | 200 mg |
| L-Arginine HCl | 100 mg |
| Herbal blend, 9 botanicals | 120 mg |
| Acetyl L-Carnitine | 50 mg |
| Pyridoxine (B6) | 4 mg |
The B6 is there, it is 4 mg, and it is printed — so you can hold it against the 1208% DV bottle in your kitchen instead of finding out in a year.
One dropper. Eight compounds.
Under the tongue in the morning. One bottle instead of the five to seven on the shelf.

Who should not buy this
It won’t be. jimhd uses a lidocaine cream at bedtime just to fall asleep. Ask your doctor about that first.
Nobody has one, including us. The most frequently credited thing in this entire body of forum writing is free: walking.
Spend that appointment before you spend $39.99. The word deserves one real conversation first.
Then don’t. Thirty days doesn’t answer the question.
One last thing
Nobody can promise you an answer to that. Not us, not your neurologist, not the clinic with the $9,600 program.
But the smaller version of that question is answerable, and it is answerable by you. Mark the line tonight. Write the date. In ninety days you will own one measurement that nobody handed you and nobody can take back.
