B vitamins
Does Quiet Nerves Contain Vitamin B12 or Other B Vitamins?
Quick answer
No. The six ingredients Quiet Nerves names are magnesium glycinate, alpha lipoic acid, butcher's broom, L-carnitine, turmeric and coenzyme Q10, and none is a B vitamin. Other ingredients are not published. Low vitamin B12 can make hands and feet numb, and a blood test can check it, so ask your doctor, especially if you take metformin.
Vitamin B shows up again and again in nerve searches: B12, B6, B1, B complex. Shoppers reasonably expect a nerve capsule to include them.
This post checks that expectation against the Quiet Nerves ingredient list, explains why B12 deserves its own test and lists the questions that make a doctor visit useful.

Why B12
Why does vitamin B12 matter for numb or tingling feet?
Low B12 may leave hands and feet numb or tingling (NIH ODS, vitamin B12). It is one of the easier causes of such symptoms to find and treat. A simple blood test can check your level.
That is why a doctor will often ask about it early. It also explains why a nerve capsule without B12 cannot be a stand-in for the test.
Risk
Who is more likely to run low on B12?
Being older, or eating no animal foods, makes low levels more likely (NIH ODS, vitamin B12). People who take the diabetes drug metformin may also be at risk, because it might reduce how much B12 the body absorbs.
- Older adults
- People who eat no animal foods
- People who take metformin
If you fit any of these and have numbness or tingling, ask about a B12 check. Do not stop metformin or any prescription on your own.
Limits
Will Quiet Nerves fix numbness caused by low B12?
No. It contains no B12, so it would not correct a shortfall. If your doctor finds low B12, the care plan will say how to correct it and how to recheck.
Other Bs
What about B1, B6 and B complex?
The sources used on this site do not rank B vitamins for nerve health, and none of them is a named Quiet Nerves ingredient. So we say nothing about the doses or benefits of B1, B6 or a B complex product. Your doctor or pharmacist can tell you whether any is right for you.
If you already take a B vitamin product, bring the bottle to your pharmacist along with the Quiet Nerves ingredient list. They can spot any overlap.
What it has
What does Quiet Nerves offer instead of B vitamins?
Six named ingredients, each with some research when tested alone, at doses the label does not publish. Alpha lipoic acid has the strongest nerve record: 600 mg a day by mouth for 5 weeks (Ziegler et al., 2006). Coenzyme Q10 and nano-curcumin each rest on one small trial (Hernandez-Ojeda et al., 2012) (Asadi et al., 2019). Magnesium data are weak, and butcher's broom was tested for leg veins alone.
None of that research tested the capsule.
Doctor
What should you ask at the visit?
- Could low vitamin B12 explain my numbness or tingling?
- Should I have a B12 blood test, especially as I take metformin?
- Are there other causes to rule out, such as diabetes or alcohol?
- Do the six Quiet Nerves ingredients fit with my medicines?
- If I try the capsule, what should I track and for how long?

Our view
Our view
A reader who expects B vitamins in a nerve capsule is not wrong to look. Here they are not among the six names. The point is not that Quiet Nerves is missing something. The point is that B12 deserves a blood test, not a guess.
Our advice is to ask about B12 first, especially on metformin. If your doctor says all is well and you still want to try Quiet Nerves, treat it as a time-limited trial.
