Top Fasting Glucose Researcher: I Found The Reason Why Your Morning Fasting Number Keeps Climbing… And Nothing Helps

We all kept failing for the same reason. I studied 39,522 prediabetics watching their morning number climb — and it explained the one thing every diet, every walk and every pill quietly misses.

11-Year Fasting Glucose Researcher & Educator, Knoxville, TN · September 2026

For eleven years I have read everything I could find about blood sugar. Not because it was my job. Because of my father.

He was “well managed” for twenty-two years. One pill, then two, then the insulin pen in the fridge door. He lost his left foot at sixty-six, and the doctor still called him well managed.

Then, at fifty-four, it was my turn. Fasting 108. The next year 112. Last spring, 117.

I did everything right. I cut the bread. I walked after supper every single night. I lost nine pounds. My A1C came back 6.2, and my doctor said, kindly, “If it’s 6.3 at the next draw, we start metformin.”

So I asked her the only question that had been keeping me up: why is my number highest first thing in the morning, when I haven’t eaten for twelve hours?

She said everybody gets a bit of a rise before dawn, and moved on to the next thing on her screen.

Nothing works.

That’s what I typed into a search bar at five in the morning, still holding the lancet.

I found 39,522 people living the exact same mornings.

I opened that thread expecting the usual advice. Cut more carbs. Walk after meals. Try the vinegar.

Instead I saw thousands of people using my exact words:

Different people. Different diets. Different doctors. But everyone described it with the same words.

Not similar words. The exact same ones.

Lunch numbers fixed. Bedtime numbers fine. And a morning number that went up while they slept, with nothing eaten, every single night.

And then, three hundred comments down, somebody had written something that stopped me.

Then I Saw Something That Made No Sense

No pitch. No link. Four short paragraphs from someone who had clearly been where I was.

I read it four times.

Made at 4 a.m.? For two years I had treated my fasting number as a grade on what I ate the day before. Every salad, every skipped roll, every walk around the block was an argument with a number that was being written while I was asleep.

I had been working the day shift as hard as a person can. And the number wasn’t coming from the day shift at all.

At 2 a.m. the next night, I found the research. And it changed everything.

It Wasn’t Your Fault. It Was Biology.

What I found has a dry name in the textbooks. After eleven years of watching it, first in my father and then on my own meter, I ended up calling it The Empty Night Shift.

The Three Things The Empty Night Shift Was Doing — Simultaneously

So the rising number, the plateau and the “doing everything right” are not three problems. They are one problem, overnight, in the muscle — and a plan aimed at your plate will polish the daytime numbers forever without touching the one your doctor actually judges you on.

What Didn’t Work — And Why

The walks, the vinegar and the cinnamon. I did all three for over a year. The walks genuinely knocked twenty points off my after-dinner number, which is real and worth keeping. But you cannot walk off a number that is made while you are asleep.

The cheap alpha lipoic acid tub. This is the one I want you to skip. When I first read that this compound works inside the muscle cell, I bought the big bargain tub. Two months, nothing. I nearly wrote the whole idea off. Then I read the fine print: it never said which form it was, and most bargain tubs are a 50/50 mix in which only half is the form your body actually makes. The label said 600 mg. A fraction of that was the part that mattered.

Berberine. Three good weeks, then a plateau and a stomach I would not wish on anyone. It works on the release side, like metformin. My night shift was still empty.

I Tried To Buy Exactly What I Needed. It Didn’t Exist.

So I went looking for the real thing.

Pure R-form. The full 600 milligrams. In oil, so the body could actually take it up.

Every bottle I picked up was the 50/50 mix, or underdosed, or dry powder in a hard capsule.

Nine brands. Hundreds of dollars. Most of a year.

Not one of them matched what the research described.

That’s when I found what actually works.

The version that matters is the R-form on its own — the half of the molecule your own cells make, the one that in lab studies moved the same sugar doorway insulin uses up to the surface of muscle cells (Estrada and colleagues, Diabetes, 1996). It has been a prescription compound in Germany since 1966. Here it sells as a supplement, which is why your doctor has probably never been told about it.

The shortcuts fail for dull reasons. The 50/50 mix is cheaper to make. Dry powder is cheaper to fill. The pure R-form is fragile and expensive, so almost nobody isolates it, and the few who do tend to cut the dose.

I found a small formulation lab that specialised in exactly this, and I asked if I could come and watch them make it.

It took months. Batches that separated. Batches that oxidised. Batches that tested under the label and went in the bin.

But it worked.

Pure R-form. 600 mg per softgel. Suspended in coconut oil rather than pressed dry into a capsule. And every single batch sent to an outside lab that has no stake in the answer.

The Night I Finally Tried It. Changed Everything.

One softgel with breakfast. That is the whole routine. No stack, no loading phase, no second bottle, no change to what I ate.

Three months later, at my spring draw, the A1C was 5.9. My doctor looked at the screen for a long second and said, “Whatever you’re doing, keep doing it. We don’t need to talk about metformin today.”

You Can Get Your Mornings Back. Forever.

I did not want to be one more stranger online with a story. So I went back to the thread that had found me, and I asked people to test it on themselves, write the number down, and report it either way.

Forty people took me up on it. Not one of them came back to tell me I was wrong.

Then it was four hundred. Then thousands. Same story in different handwriting: the gap between bedtime and morning closes first, the morning number starts sliding a few points a week, and the thing they had been told was “just genetics” turns out to have had a cause the whole time.

Don’t Take My Word For It — Take Theirs

You Have Two Choices Right Now

I’m Not Selling You Hype. I’m Showing You What Worked.

Ninety days. If your morning number hasn’t moved, you write one email and you get every penny back. You keep the pouch.

• Aimed at the muscle, not the meal — in lab studies R-ALA moved the same sugar doorway insulin uses (Estrada et al., Diabetes, 1996)
• The pure R-form only — not the 50/50 bargain mix
• 600 mg per softgel, in coconut oil — not dry powder in a hard capsule
• Honest about the size — a slow slide measured in points, not a miracle; the pooled studies at this dose averaged about 9 points on fasting glucose

I spent two years and $3,380 out of my own pocket chasing that morning number before I understood when it was being made. I kept the paperwork.

Here’s Exactly What Happens When You Order

One more thing: every order comes with the First Week Guide — the short answer to the questions everybody sends me, including how to take it alongside a prescription and why the first week often shows nothing at all.

That’s it. No extra pills. Just the R-form at the dose that was actually studied.

This Isn’t Amazon. We Make Small Batches.

Two Questions To Ask Yourself

If the answer to both is no, here’s the whole thing in one line:

If it doesn’t work, you get your money back. If it does, you get your mornings back.

That thread is still going. It finds somebody new every week — usually before sunrise, usually typing the same question I typed: why is my number higher than when I went to bed?

P.S. — People ask why we don’t just mass-produce it and put it on every pharmacy shelf. Because the expensive part is the part everyone else cuts. The moment you scale this, you start buying the 50/50 mix, and the moment you buy the mix you are selling the bargain tub that wasted two months of my life.

You’ve Been Burned Before. Here’s Why This Is Different.

Ninety days. Full refund, any time inside that window, for any reason. You keep the pouch whether it is full or empty. You don’t ship anything back.

I know exactly what it feels like to spend money on hope and get nothing, because berberine, cinnamon, vinegar and a bargain tub all did it to me first.

Of the 39,522 people in this, three have asked for a refund. Either it moves your number or it costs you nothing — those are the only two outcomes on offer.

So wherever you are right now — notebook by the coffee pot, draw on the calendar, doctor’s warning still in your ears — you can be the next person that thread finds.

The morning I took the first one I almost didn’t bother. I had a cupboard of bottles that had all promised me something, and I genuinely believed I was buying disappointment number ten.

Six weeks later I was writing 104 in a notebook and eating birthday cake without lying awake about it. Three months later my doctor put the metformin conversation away.

My father never got that. He was managed, carefully and kindly, for twenty-two years, and nobody ever once asked what his muscles were doing at four in the morning. That is the part I can’t let go of.

Maybe you are where I was — doing everything right, watching the number climb, one draw away from the prescription. If you are, give yours the same ninety days I gave mine. Write the number down. Let the notebook tell you.
