Vitamin B6 in NervoMax: What It Does, Safe Limits and Why the Amount Matters
Your nerves need a little vitamin B6: adults need 1.3 to 1.7 mg a day (NIH ODS, Vitamin B6). Too much B6 can itself cause numbness and tingling. The U.S. upper limit is 100 mg a day and the EU level is 12 mg (NIH ODS, Vitamin B6). NervoMax does not print its B6 amount, so add up your other B6 products and ask your doctor.

The basics
Why do nerves need vitamin B6?
Vitamin B6 helps run more than 100 enzyme reactions, including ones that make the chemical messengers nerves use (NIH ODS, Vitamin B6). You need only a small amount. Most U.S. adults get enough from fish, poultry, potatoes, chickpeas, bananas and fortified cereals (NIH ODS, Vitamin B6).
| Label name | Vitamin B6 (as Pyridoxine) |
|---|---|
| What it is | Pyridoxine · B vitamin |
| Position on the label | 6 of 9 (labels list blend ingredients from most to least by weight) |
| Amount on the label | Not printed (inside the blend) |
| What research has used | RDA 1.3-1.7 mg; U.S. upper limit 100 mg |
| Strength of evidence | Needed for nerves; too much harms them |
| What it is sold for | Essential vitamin for nerve and brain chemistry |
| Main caution | Too much B6 can cause numbness and tingling; NervoMax does not print its amount. |
The twist is simple. A little supports nerves. A lot, taken for months, can harm the same nerves (Muhamad et al., 2023). So the amount matters more for B6 than for almost any other vitamin.
Numbers
How much vitamin B6 is too much?
Adults need 1.3 mg a day up to age 50, then 1.7 mg for men and 1.5 mg for women (NIH ODS, Vitamin B6). The limits sit far higher.
Vitamin B6 benchmarks come from the NIH fact sheet (NIH ODS, Vitamin B6) and Australia's TGA (TGA, B6 alert 2022). NervoMax does not print its B6 amount, so you cannot place it on the first chart. The second chart shows that three of the nine ingredients alone, at study doses, would need most of the whole blend.
The U.S. upper limit is 100 mg a day. In 2023 the EU set 12 mg, after newer reports showed nerve problems well under 100 mg (NIH ODS, Vitamin B6). Australia requires a label warning above 10 mg (TGA, B6 alert 2022).
Safety reports
What have regulators reported about B6 and numbness?
Australia, 2025
Reports reached 250 by October 31, 2025. Products over 50 mg a day turn pharmacist-only on June 1, 2027 (TGA, B6 update 2025).
New Zealand, 2025
Five of six local reports involved a dietary supplement, often a lower dose taken for a long time (Medsafe, B6 2025).
The Netherlands, 2018
In 90 reports, products held 1.4 to 100 mg per tablet. Harm below 50 mg could not be ruled out (van Hunsel et al., 2018).
A 2023 systematic review of 20 studies found a mostly sensory neuropathy that improved after people stopped, and no proven safe threshold (Muhamad et al., 2023). U.S. federal experts list chronic high-dose B6 as a cause too (NCCIH, Cognition digest).
The label
How much vitamin B6 is in NervoMax?
The label does not say. B6 sits inside the 600 mg blend with no amount, though FDA's guide says vitamins with Daily Values are normally listed with their own amounts (FDA, Labeling guide).
Label order gives only a ceiling. Blend ingredients run from most to least by weight (21 CFR 101.36), and five sit above B6. So B6 cannot top one-sixth of 600 mg: 100 mg per 2 capsules. The real amount could be far lower.
Call the order desk at +1 (302) 200-3480 and ask for the B6 amount per serving in writing. No number means unknown. The full panel is on our NervoMax Supplement Facts page.
Four steps
How do you add up your vitamin B6?
- 01
Line up every label
Gather every supplement you take: B-complex, multivitamin, magnesium, sleep or energy blends, and NervoMax.
- 02
Write B6 per serving
Find vitamin B6 (pyridoxine) on each panel. Multiply the mg by the servings you really take each day.
- 03
Add the daily total
Compare the sum with 12 mg (EU) and 100 mg (U.S. limit). Mark NervoMax as unknown.
- 04
Check it with your doctor
Bring the list and the bottles. Ask whether your total makes sense and whether a B6 blood test is worth doing.
Other products
Which other supplements contain vitamin B6?
| Product | B6 per serving | What to check |
|---|---|---|
| B-complex | Varies widely | Dutch cases: 1.4 to 100 mg per tablet |
| Multivitamin | Varies | The mg on the Supplement Facts |
| Magnesium tablets | Some hold 60 mg | Found in Australian products (Daley et al., 2023) |
| NervoMax | Not published | Ask the order desk |
The same Australian study found high B6 in about 39% of 88,655 blood samples (Daley et al., 2023).
A 45-year-old takes a B-complex and a magnesium tablet daily. If they held 50 mg and 60 mg, she would reach 110 mg before NervoMax. That is over the U.S. limit, and her NervoMax share stays a blank.
Warning signs
What are the signs of too much vitamin B6?
Numbness or tingling in the feet and hands, sometimes with burning or an unsteady walk (NIH ODS, Vitamin B6) (Muhamad et al., 2023). Those match what NervoMax is sold for, so too much B6 can look like the problem getting worse.
Stop NervoMax and every other B6 product. See your doctor with all the bottles and ask about a B6 blood level.

FAQ
Vitamin B6 in NervoMax: common questions
How much vitamin B6 is in NervoMax?
The label does not print it. B6 sits inside the 600 mg blend with no amount. Label order caps it at 100 mg per 2 capsules, since five ingredients weigh more, but it could be much lower. Ask the order desk for the number in writing.
Can vitamin B6 cause numbness and tingling?
Yes. Too much B6 over time can cause sensory neuropathy: numbness, tingling and burning in the hands and feet. Australia reports cases below 50 mg a day, and a 2023 review found no proven safe threshold. Symptoms usually improve after stopping.
What is the upper limit for vitamin B6 per day?
The U.S. adult upper limit is 100 mg a day from all sources. The European Union set 12 mg a day in 2023, and Australia requires a warning above 10 mg. Adults need only 1.3 to 1.7 mg a day.
Can I take NervoMax with a B-complex or magnesium?
Ask your doctor first. Both often contain B6, and some magnesium tablets hold 60 mg each. NervoMax does not print its B6 amount, so you cannot add up your total alone. Bring every bottle to the appointment.
Is 10 mg of vitamin B6 a day too much?
Not for most adults by U.S. or EU limits. Still, Australia requires a nerve warning above 10 mg, and New Zealand saw cases from lower doses taken for a long time. Your total from all products is what counts.
Should I get my vitamin B6 level tested?
Ask your doctor if you take several supplements or notice new tingling. A blood test can show a high B6 level. An Australian lab study found high B6 in about 39% of 88,655 samples, so it is more common than people expect.
