Burning, tingling or numb feet are among the most common nerve complaints in older adults. Before choosing any supplement, it helps to know what usually causes them.
1. High blood sugar
Diabetes is the most common cause of nerve damage in the feet. Long-term high blood sugar harms the small vessels that feed nerves.
2. Low vitamin B12
B12 is needed for healthy nerve coating. Low levels are common with age, with metformin use and in people who eat little animal food. A blood test can check it.
3. Alcohol
Heavy, long-term drinking is toxic to nerves and often lowers vitamin levels too.
4. Thyroid problems
An underactive thyroid can cause fluid build-up that presses on nerves.
5. Pressure on a nerve
Back problems and tight spots such as the tarsal tunnel at the ankle can squeeze a nerve.
6. Medicines
Some chemotherapy drugs and other medicines list nerve symptoms as side effects.
7. Circulation problems
Narrowed arteries can reduce blood flow to the feet, causing pain and cold skin.
Where supplements fit
Supplements such as Arialief are designed to support nerve comfort, not to treat these causes. Get a diagnosis first, treat what can be treated, then decide whether a supplement is worth adding.
