‍

I'm going to tell you something the $35 billion neuropathy drug industry would rather you never read.

‍

After 18 years treating peripheral neuropathy patients — watching the same people cycle through the same medications for the same temporary relief followed by the same crushing return of symptoms — I decided I was done staying quiet.

‍

What's happening to neuropathy patients isn't incompetence.

‍

It's by design.

‍

My name is Dr. Sarah Kellerman. I'm a doctor of physical therapy specializing in peripheral nerve recovery. I've treated over 6,000 patients. I've published research. I've trained other PTs.

‍

And two years ago, while watching my father shuffle through our kitchen at 3 AM because the floor felt like broken glass under his feet...

‍

I realized I'd spent nearly two decades helping people manage a problem I had never actually helped anyone solve.

‍

‍

MY FATHER HAD TRIED EVERYTHING

‍

His neuropathy started after a decade of type 2 diabetes. The burning began at the toes, crept to the ankles, and turned his feet into something between numb and unbearably sensitive at the same time.

‍

He described it as "standing on hot sand that also can't feel anything."

‍

He slept with one foot out from under the covers, because the sheet on his toes felt like it was on fire.

‍

His neurologist prescribed Gabapentin. Then Lyrica. Then both.

‍

He gained 22 pounds. The brain fog was so bad he stopped doing the crossword puzzle he'd done every morning for 30 years. The pain came back anyway.

‍

Twice that winter he fell, and had to call me to come help him up off the floor.

‍

He tried B12 injections. Nerve conduction studies. Alpha-lipoic acid supplements. Physical therapy three times a week at $90 a visit.

‍

Temporary relief. Every single time.

‍

His podiatrist told him this was simply what living with neuropathy meant.

‍

I believed it too. Because that's what we were trained to believe.

‍

‍

THE NIGHT I STARTED QUESTIONING EVERYTHING

‍

That night in the kitchen, watching him grip the counter to steady himself, I opened my laptop and started reading primary research — the kind buried in journals that general practitioners never have time to open.

‍

Four months later, I had found something that contradicted nearly everything I had been trained to believe.

‍

Peripheral nerves can regenerate.

‍

‍

Not in every case. Not overnight. But the medical literature is unambiguous: given the right conditions, peripheral nerve fibres can grow back at approximately 1–2mm per day.

‍

The question was never whether healing was possible.

‍

The question is why those conditions are almost never created by standard treatment.

‍

‍

THE REAL REASON NEUROPATHY FEELS PERMANENT

Damaged nerves don't stay broken because the damage is irreversible.

‍

They stay broken because the environment around them never supports repair.

‍

Peripheral nerve regeneration requires four specific conditions to occur simultaneously:

‍

1. Low systemic inflammation — Nerves cannot repair in a body that is constantly inflamed. Diabetic and aging patients typically carry chronic, body-wide inflammation that never fully switches off. While it's burning, the nerve spends everything defending itself and nothing on repair. It's why cutting sugar helps some people a little.

‍

2. A calm nervous system — Magnesium is what tells an overexcited nerve to stand down. Most neuropathy patients, especially diabetics, run chronically low on it. Without it, the nerves stay stuck firing pain signals even when nothing is touching your feet. It's why the pain goes crazy at night, and why an Epsom salt soak feels good for an hour.

‍

‍

3. An intact protective coating — B12 is what makes the protective layer around your nerves, along with folate and B6. Diabetics on metformin are commonly depleted in B12. When the coating wears thin, the signal leaks out, and you get the tingling and the numbness. It's why your doctor checked your B12.

‍

4. Cellular energy — This is the part nobody talks about. Every nerve cell runs on a molecule called NAD+, the fuel its energy factories use for every repair job it does. Research published in the journal PLoS ONE found NAD+ levels drop sharply with age, and high blood sugar burns through it even faster. Without it, the nerve is starving, and the other three conditions are necessary but not sufficient. It's why so many people are told their neuropathy is "permanent." It isn't dead. It's starving.

‍

Miss any one of these four. The healing cycle stalls.

‍

That is why Gabapentin doesn't fix neuropathy. It suppresses the signal — which is why so many people feel like a zombie on it — but does nothing for conditions 1 through 4. That is why B12 helps some people slightly — it partially addresses condition 3, but doesn't touch 1, 2, or 4.

‍

This is what I wish someone had told my father years earlier.

‍

‍

THE PROTOCOL THAT CHANGED EVERYTHING

I spent six months developing what I now call the Nerve Renewal Protocol — a sequenced approach that delivers all four regeneration conditions in a single 30-second morning routine.

‍

‍

Phase 1: Inflammation Defense CoQ10 and pterostilbene, an antioxidant found in blueberries, help protect nerve cells from the daily "rust" that high blood sugar and chronic inflammation leave behind, so the nerve can stop defending itself and get back to repair.

‍

Phase 2: Nerve Calming Magnesium glycinate, the gentle form of magnesium that's easy on the stomach, to help an overexcited nerve stand down, especially at night.

‍

Phase 3: Coating Support The exact B vitamins the protective coating is built from: B12, folate and B6, plus TMG to keep that process running.

‍

Phase 4: Cellular Fuel NR (nicotinamide riboside) at 300mg, the dose used in human research, where it raised blood NAD+ levels by 51% in two weeks. It's a liquid held under the tongue, with the NR wrapped in tiny fat bubbles, so it skips the swallow and doesn't have to take the long way through your stomach.

‍

‍

All four phases, in one liquid: CelluNAD+. Two droppers under the tongue each morning. Hold for 30 seconds. That's the whole protocol.

‍

More energy. More capacity for repair.

‍

This is the phase none of his medications ever touched.

‍

This is also the phase that changes everything.

WHAT HAPPENED WHEN I TESTED IT

‍

My father was the first person I put through the full protocol.

‍

After three weeks of it every morning, he walked through our kitchen without holding the counter.

‍

He didn't say anything at first. He just walked back and forth twice.

‍

Then he said: "The floor feels like a floor."

‍

I have been a physical therapist for nearly two decades. I had never cried during a clinical observation.

‍

Within eight weeks, he had reduced his Gabapentin dose by half. His sleep improved. He started the crossword again.

‍

"I cried the first morning I woke up without that burning feeling. I didn't think that was possible for me anymore."
Christine, 58 ⭐⭐⭐⭐⭐

"I was on 900mg of gabapentin and it barely touched the pain. After three weeks with CelluNAD+, I talked to my doctor about reducing my dose. My feet feel like mine again."
Joseph, 71 ⭐⭐⭐⭐⭐

"The numbness in my toes has improved more in two months than in three years of prescriptions."
Trish, 64 ⭐⭐⭐⭐⭐

WHAT THIS COSTS COMPARED TO "MANAGING" IT FOREVER

‍

The standard neuropathy management path:

‍

  • Gabapentin (600mg/day): $80–$120/month, indefinitely
  • Lyrica (pregabalin): $150–$250/month, indefinitely
  • Podiatry visits: $120/visit × 6–12/year = $720–$1,440/year
  • Traditional physical therapy: $90/session × 2–3×/week = $700–$1,000/month
  • Alpha-lipoic acid infusions: $300–$600/series

‍

Annual cost of managing neuropathy without addressing root cause: $3,000–$8,000+

‍

Every dollar spent on Gabapentin delivers zero input into conditions 1 through 4.

‍

CelluNAD+ delivers all four. Every day. At home. No appointments. No prescriptions. For less than one podiatry visit a month.

‍

‍

P.S. My father just completed a 1 mile walk with his grandchildren. First time in four years. He still sends me a photo every Sunday morning.

‍

P.P.S. If you're currently taking Gabapentin or Lyrica and see improvement with the protocol, reduce your dose only in consultation with your prescribing physician. But don't wait to start.
