Does apple cider vinegar help with neuropathy? What the research does and doesn't show

What people actually search for here is neuropathy, not seizure disorders — there's no research connecting apple cider vinegar to seizures, so this page answers the neuropathy question instead. No trial has tested apple cider vinegar for neuropathy, nerve pain or any nerve-related outcome. What is documented is apple cider vinegar's research on blood sugar in people with type 2 diabetes, a different measurement from nerve symptoms.

What the evidence doesn't support

It doesn't support apple cider vinegar as a treatment for neuropathy, nerve pain, or nerve damage of any kind — no trial has tested it for that. It doesn't support a claim connecting apple cider vinegar to seizure disorders either; we found no research on that topic at all. And where apple cider vinegar does have research — blood sugar in type 2 diabetes — that's a marker measured in blood, not a measurement of nerve function or nerve symptoms, and the two shouldn't be assumed to move together.

What the trials found

The trials that exist on apple cider vinegar measure blood sugar and related metabolic markers, not nerves. An 8-week randomized controlled trial gave adults with type 2 diabetes 30 mL/day of apple cider vinegar and found fasting blood glucose dropped significantly more in the vinegar group than in a control group following the same general diet advice; see apple cider vinegar and diabetes: what the research does and doesn't show for the full set of findings. None of that research measured nerve conduction, nerve pain, tingling, numbness or any other neuropathy symptom — it's a separate line of measurement that this literature simply doesn't touch. A systematic review of 13 human and 12 animal studies on apple vinegar's safety and metabolic effects tracked glycemic and weight-related outcomes; it did not track nerve-related outcomes either.

Diabetic neuropathy — the most common reason someone searching "apple cider vinegar for neuropathy" would be looking — is a distinct, diagnosed complication of long-term blood sugar exposure, evaluated through nerve-conduction testing and clinical exam, not through fasting glucose alone. Nothing in apple cider vinegar's blood-sugar research has been tested against that diagnosis or its symptoms.

Questions people ask

Does apple cider vinegar help with neuropathy?

No trial has tested it. Apple cider vinegar's research is on blood sugar markers in people with type 2 diabetes, not on nerve symptoms, nerve damage, or neuropathy diagnoses.

Can apple cider vinegar help with nerve pain?

We found no published trial testing apple cider vinegar for nerve pain of any cause.

Does apple cider vinegar help with diabetic nerve damage?

Apple cider vinegar's trials measure blood sugar, not nerve damage or nerve-conduction outcomes, and diabetic neuropathy is diagnosed and monitored separately from blood sugar readings. No trial has tested apple cider vinegar against a neuropathy outcome specifically.

When to talk to a doctor

Numbness, tingling, burning pain or weakness in the hands or feet are symptoms worth raising with a doctor, especially with diabetes or prediabetes. Apple cider vinegar is not a treatment for neuropathy, and nothing in its research above supports using it as a substitute for medical evaluation or a prescribed treatment plan. If you take insulin or another glucose-lowering medication, talk to your doctor before adding a supplement that can shift blood sugar readings.
