I’m a Nephrologist. If Your A1C Is Between 6.4 and 7.2, Here’s Exactly What I Would Do to Avoid the Dialysis Chair
I’m a nephrologist, and if your A1C is between 6.4 and 7.2, here’s exactly what I would do to avoid the dialysis chair.
I would stop pretending that monitoring the decline is a plan.
That is not a plan.
That is a countdown.
Dr. Mark Callahan, MD — Nephrologist
18 years in nephrology. Has watched blood sugar dissolve kidneys from the inside out. Has sat across from patients and explained what dialysis means — three times a week, four hours a session, hooked to a machine.
I’ve watched it drain bodies, drain savings, drain entire families.
And I’ve watched men come into my clinic who followed every instruction — took the pills, tracked the number, kept every appointment — and still ended up with a GFR dropping two points every quarter.
Here is what your A1C is not showing you
Your kidneys are under sustained attack from high blood sugar. Glucose circulating through your blood is destroying your nephrons one by one. Those are the filtering units inside your kidneys that clean your blood. You have roughly one million in each kidney.
They do not grow back.
High blood sugar accelerates this. High blood pressure pours fuel on it. The glucose circulating through your kidney’s tiny capillary walls, hour after hour, year after year, grinds those walls thinner from the inside.
Think of it like fine sand moving through a water pipe
It makes no sound. It leaves no warning. It just wears the interior thinner, grain by grain, until one day you see foam in your toilet that will not flush away — protein leaking out of filters that have been quietly failing for years.
“Your blood pressure medication manages the pressure. It does not stop the damage high blood sugar is doing inside your kidney tissue.”
— Dr. Mark Callahan, MDThe research that changes the conversation
There is a specific compound that addresses high blood sugar directly at the cell level. Most medications reduce the amount of glucose in the blood. What they do not do is fix why the glucose is staying in the blood in the first place.
True Ceylon cinnamon — not cassia, not the spice in your cabinet — contains active compounds called Type-A Polymers and MHCP. These compounds go directly to the cell and trigger the GLUT4 transporters to surface.
A study in the Journal of the American College of Nutrition found that MHCP was 20 times more effective at activating this cellular pathway than any other natural compound tested.
Why most cinnamon products fail
Three reasons most products don’t work
1. Wrong species. Most products labeled “cinnamon” are actually Cassia. At therapeutic doses, cassia burdens the liver with coumarin.
2. Catastrophically underdosed. Clinical trials used 6,000–7,200mg equivalent. Most capsules contain only 500–1,500mg of powder.
3. Wrong delivery format. The active compounds are fat-soluble. Dry powder capsules have poor absorption. The right carrier is MCT oil.
The version that actually matches the research is Primal Remedies.
True Ceylon cinnamon (Cinnamomum verum), DNA-verified, sourced from Sri Lanka. 7,200mg equivalent per serving (2 softgels). Suspended in MCT oil. Third-party tested.
What happened when I started recommending it
Patient Example
Type 2 for eleven years. A1C at 6.8. On metformin and a blood pressure pill. Protein spillage 510 mg. GFR 46.
Three months later: GFR 51. Protein spillage 280. Fasting glucose from 138 → 104.
What I Told Him
“Your numbers are improving.”
He smiled.
“The drain opened.”
Three options
Option 1: Keep monitoring the decline. Watch the GFR drop a point or two every quarter.
Option 2: Accept that “managed” is as good as it gets.
Option 3: Open the drain. Try the version of Ceylon cinnamon that matches the clinical dose and delivery method. Give it 90 days.
