B vitamins and nerves
B vitamins nerve health: what the sources say
B vitamins nerve health depends on whether you are short of one, and a blood test answers that better than guessing. NIH says a B12 shortage can cause numbness and tingling in hands and feet. NINDS also lists too much B6 as a cause. Flow Nerves names no B vitamin among its six ingredients.

The vitamins
Which B vitamins are linked to nerve symptoms?
B12 is the one with the clearest link: NIH says deficiency can cause numbness and tingling in the hands and feet, even without anemia (NIH ODS, Vitamin B12). B6 appears on the list from the other side, because too much can be a cause.
| Vitamin | What the source says |
|---|---|
| B12 | Shortage can cause numbness and tingling; the RDA is 2.4 mcg and NIH sets no upper limit (NIH ODS, Vitamin B12) |
| B6 | NINDS lists excess B6 among causes of peripheral neuropathy (NINDS, Peripheral neuropathy) |
| Other B vitamins | Mayo Clinic lists low B vitamins among causes (Mayo Clinic, Peripheral neuropathy) |
Test or guess
Does a B complex help neuropathy?
We cannot say, because we read no trial of a B complex for neuropathy and so give no trial dose or duration. The sources point to checking for a shortage instead of adding vitamins blind.
NIH names higher-risk groups: older adults, people who eat few or no animal foods, people with pernicious anemia or stomach and bowel conditions, and people taking metformin or acid reducers (NIH ODS, Vitamin B12). A clinician can order a B12 test. Do not start high-dose B6 or B12 on your own, and ask a pharmacist how any vitamin fits with your medicines.
The six ingredients
How does the evidence for Flow Nerves' ingredients compare?
Flow Nerves names no B vitamin. Its six named ingredients are magnesium glycinate, alpha lipoic acid, butcher's broom root extract, L-carnitine, turmeric extract and coenzyme Q10.
The meters are an editor's reading of human studies for nerve symptoms, not a rating of the capsule. No amount is printed for any ingredient, and we hold no Supplement Facts panel.

Should you add B vitamins to a nerve supplement?
Ask first. A B12 shortage is only one of several causes, and the others, such as diabetes or alcohol, need their own care (Mayo Clinic, Peripheral neuropathy). See B12 and nerve health.
Keep taking prescribed medicine as directed. Sudden numbness or weakness, especially on one side, trouble speaking, chest pain or trouble breathing: call 911.

FAQ
Flow Nerves questions people ask
Can too much vitamin B6 hurt nerves?
NINDS lists excess B6 among the causes of peripheral neuropathy. Ask a pharmacist before taking a high-dose B6 or B-complex product, and tell your clinician about every supplement.
Does Flow Nerves contain vitamin B12?
No. The seller names six ingredients and no B vitamin. B12 is not one of them, so a Flow Nerves capsule does not stand in for a B12 test.
How do I know if I am low in B12?
A blood test through your clinician is the way to find out. NIH lists older age, a diet with few or no animal foods, metformin and acid reducers as risk factors.
