If your feet tingle
What can cause numbness and tingling in the feet?
Many things can cause numb or tingling feet, and diabetes is the leading cause of peripheral neuropathy in the U.S. (NINDS, Peripheral neuropathy). Low B vitamins, alcohol use, injury, some medicines and other health problems are on the list as well.
A doctor can tell them apart with an exam and tests. A supplement cannot. That is why every guide here points to a checkup first.
- DiabetesThe leading cause of peripheral neuropathy in the U.S.; about two thirds of people with diabetes have nerve problems of some degree. (NINDS, Peripheral neuropathy) (ADA, Neuropathy and diabetes)
- A vitamin shortfallB vitamins, copper and vitamin E matter to nerves. With low B12, numbness and tingling in the hands and feet can occur. (Mayo Clinic, Peripheral neuropathy) (NIH ODS, Vitamin B12)
- AlcoholAlcohol use disorder can damage nerves directly and by lowering vitamins. (Cleveland Clinic, Peripheral neuropathy) (Mayo Clinic, Peripheral neuropathy)
- Injury or pressureA crush, a fracture, a slipped disk or repeated pressure on a nerve can all cause symptoms. (NINDS, Peripheral neuropathy) (Mayo Clinic, Peripheral neuropathy)
- MedicinesSome medicines, especially chemotherapy, can cause peripheral neuropathy. (Mayo Clinic, Peripheral neuropathy)
- Other health problemsInfections such as shingles, autoimmune conditions, kidney, liver or thyroid disease, and inherited conditions are on the list. Sometimes no cause is found. (Mayo Clinic, Peripheral neuropathy) (MedlinePlus, Peripheral nerve disorders)

Supplement safety
How do you check a nerve supplement against your medicines?
You check a nerve supplement against your medicines by asking a pharmacist, and our Switchboard gives you a head start. Tap each medicine you take, and a wire lights up to every Flow Nerves name that a source links to it.
- Diabetes medicine or insulin, and blood thinners, are the first two to raise.
- Blood pressure, prostate, thyroid and seizure medicines, and antibiotics, come next.
- Tell the pharmacist about kidney or liver disease, pregnancy, nursing and surgery.
Natural does not mean free of interactions. Keep taking prescribed medicine, and do not stop or change it because of a supplement. Open the medicine Switchboard and bring the results to your pharmacist.
Prepare for a visit
What should you take to a doctor visit about nerve symptoms?
Take a short note of your symptoms, your medicines and your supplements. CDC says to keep notes on symptoms to share with your doctor (CDC, Diabetes and nerve damage). Tick what applies below and copy the note.
A note-taking aid, not a test. CDC suggests keeping notes on symptoms to share with your doctor (CDC, Diabetes and nerve damage), and Mayo Clinic says to seek medical care right away for tingling, weakness or pain in your hands or feet (Mayo Clinic, Peripheral neuropathy).
Bring a photo of any supplement label. The Flow Nerves label prints no amounts, so your doctor may want to see the bottle.
How we write
How are these nerve supplement guides written?
The guides are written by the Flow Nerves label desk from public health sources, with every statement tied to a source or marked as unknown. They make no claim that Flow Nerves, or any ingredient in it, helps a condition.
- Sources are government and hospital pages, review articles and the federal supplement rules. The list is at the foot of each guide.
- Studies are tied to one ingredient, one dose and the people studied. No study of Flow Nerves exists in our sources.
- Where we found nothing, the guide says we found no source.
- Each guide carries a medical reviewer slot. It stays marked until a named reviewer is added, so no guide claims a review it does not have.
