Neuropathy Supplement Acid: Alpha-Lipoic Acid and Others, Checked
A neuropathy supplement acid is any acid sold for nerve talk, most often alpha-lipoic acid, folic acid or an amino acid. The Cochrane reviews we cite found little or no clear benefit from alpha-lipoic acid and from B vitamins. The cause of numbness is for a doctor to find first.

The acids01
What counts as a neuropathy supplement acid?
A neuropathy supplement acid is a compound with “acid” in its name that is sold in nerve products, such as alpha-lipoic acid or folic acid.
The word says nothing about the amount or any nerve benefit.
| Name | What it is | What the reviews say |
|---|---|---|
| Alpha-lipoic acid | An antioxidant the body makes | Little or no clear benefit (Cochrane, Alpha-lipoic acid for diabetic neuropathy) |
| Folic acid, B vitamins | Vitamins in food | Little or no clear benefit (Cochrane, Vitamin B for neuropathy) |
| Amino acids | Protein building blocks | No nerve trial in our sources |
Causes02
Does low vitamin B12 matter more than the acid you take?
Low vitamin B12 matters more, because it is a known, testable cause of numbness and tingling.
A blood test can check it (MedlinePlus, Numbness and tingling). Keep taking prescribed medicine and ask your doctor or pharmacist before adding a supplement.
Warning signs03
When do numb feet need a doctor before any supplement?
Numb feet need a doctor first when they are new, spreading, painful at night or paired with weakness.
A bottle should not delay the visit (NINDS, Peripheral Neuropathy).
- Spreading or constantNumbness or tingling that keeps getting wider, or never goes away
- WeaknessDropping things, tripping, or a foot that slaps or drags
- Balance and fallsUnsteady walking, especially in the dark, or new falls
- Sores you do not feelCuts, blisters or color changes on the feet, most important with diabetes
- Burning pain at nightPain that wakes you, or a sock or sheet that hurts to touch
See a doctorAny of these, or tingling that is getting worse, is a reason to see a doctor. Many causes, such as diabetes or low B12, can be treated, and early treatment protects nerves. A supplement should not delay it.
Go nowNumbness with weakness, trouble speaking, confusion, vision change, loss of bladder or bowel control, or after a head, neck or back injury needs emergency care. Call 911 or go to an emergency room.
Warning signs from NINDS and MedlinePlus (NINDS, Peripheral Neuropathy) (MedlinePlus, Numbness and tingling).

FAQ05
Questions about neuropathy supplement acid
Is alpha-lipoic acid the same as folic acid?
No. Alpha-lipoic acid is an antioxidant the body makes. Folic acid is a B vitamin. Each has its own Cochrane review. Neither found a clear nerve benefit.
Can an amino acid help neuropathy?
The sources we cite show no nerve trial for an amino acid supplement. Amino acids come from protein foods, so ask a doctor if your diet is low in protein.
Should I take an acid supplement for tingling feet?
Not before a doctor checks the cause. Diabetes, low B12 and pinched nerves are treatable causes. Add a supplement only if your doctor agrees, and keep taking prescribed medicine.
