Symptoms
Why Do Feet Tingle at Night? Causes, Daily Foot Care and Where Supplements Fit
Quick answer
Tingling feet at night can come from nerve trouble with causes such as diabetes, low vitamin B12, alcohol and some medicines, so a doctor visit comes first. Daily foot checks matter most if you have diabetes. Supplements are not a treatment, and Quiet Nerves publishes no ingredient amounts.
Feet are often the first place nerve trouble shows, and the signs can climb upward over time. Tingling, buzzing or burning can be the first hint.
This post covers the likely causes, a foot-care routine, the signs that need quick help and a sober look at what a capsule can add.
Key facts
- Many people first notice nerve trouble in the toes and feet, and it can creep upward over time.
- In the US, diabetes is the top cause of nerve damage. Low vitamin B12, alcohol, medicines and infections are others.
- Numb feet may not warn you about a blister or a stone in a shoe.
- A foot cut, sore or blister that is not healing needs a call to your doctor within days.
- Metformin may cut the B12 your body takes in.
- Quiet Nerves is not a treatment, and it has no vitamin B12 in it.
Feet
Why do the feet show nerve trouble first?
Many people notice it in the toes and feet first, and it can creep upward over time (NINDS, peripheral neuropathy). When sensory nerves are damaged, signals get scrambled. You feel numbness, tingling, burning or pins and needles.
The sources we cite do not explain why symptoms can seem louder at night. So describe your own pattern to your doctor: when it starts, how long it lasts and what eases it.
Causes
What are the common causes of tingling in the feet and legs?
| Cause | What the sources say |
|---|---|
| Diabetes | The leading US cause. Years of high blood sugar can harm nerves and the small vessels that feed them (NIDDK, diabetic peripheral neuropathy) |
| Low vitamin B12 | Can leave hands and feet numb or tingly. A blood test can find it (NIH ODS, vitamin B12) |
| Alcohol | Years of heavy drinking can damage nerves |
| Medicines | Certain cancer drugs, and a handful of other medicines, can reach the nerves |
| Infections | Some can damage nerves directly or through the body's response |
| Other causes | Injuries, kidney or thyroid problems, autoimmune disease, inherited conditions, or none found |
B12
Could vitamin B12 or metformin be involved?
The diabetes drug metformin might reduce how much B12 your body absorbs and lower blood levels over time (NIH ODS, vitamin B12). Risk of low levels is also higher for older adults and for people whose diet has no animal foods.
If you take metformin, ask your doctor whether a B12 blood test makes sense. Do not drop a prescribed medicine without your doctor.
Routine
What daily foot care helps if you have diabetes?
Numb feet may not warn you about a blister or a pebble in a shoe, so small injuries can slip by and turn into sores (NIDDK, diabetic peripheral neuropathy). A short daily routine catches them early.
- Look at both feet every day: tops, soles, heels and between the toes. Use a mirror if bending is hard.
- Use lukewarm water, and check it with your elbow because numb feet cannot tell if it is too hot. Dry carefully between the toes.
- Moisturize dry skin, but keep lotion out of the gaps between toes.
- Wear socks and shoes indoors and out, and feel inside each shoe before you put it on.
- Phone your doctor about a cut, sore or blister that will not heal, or skin that turns red and swollen.
Urgent
When should tingling feet send you to a doctor quickly?
- Call 911 for sudden numbness or weakness in the face, arm or leg, especially on one side, or sudden trouble speaking, seeing or walking.
- Call your doctor within days for a foot sore that will not heal, red, warm or swollen skin, new tingling after a new medicine, or falls and tripping.
- Call your doctor within days for burning pain that keeps you awake.
- Raise mild, on-and-off tingling at your next routine visit.
Basics
What everyday habits support nerve health?
The best-supported habits are not products. Blood sugar, blood pressure and cholesterol control help prevent nerve damage in diabetes (NIDDK, diabetic peripheral neuropathy). Regular activity helps blood sugar and circulation. Less alcohol and not smoking protect the blood vessels and nerves of the feet and legs.
Good shoes help too: room for the toes, no rubbing seams and clean, dry socks each day.
Supplements
Do supplements help tingling feet?
A few single ingredients have been tested in people with diabetic nerve symptoms. Alpha lipoic acid at 600 mg a day by mouth beat placebo in a 5-week trial (Ziegler et al., 2006), though a review called the oral benefit unclear (Mijnhout et al., 2012). None of this is a promise for any capsule.
Quiet Nerves names six ingredients, including alpha lipoic acid, and publishes no amount for any of them. No study of the capsule exists.
| Item | What is published |
|---|---|
| Six ingredients named | Coenzyme Q10, turmeric (95% curcuminoids), L-carnitine, butcher's broom, alpha lipoic acid and magnesium glycinate |
| Amount of each one | Not published |
| Study of Quiet Nerves itself | Not published; none was found |
| Cost per day at one capsule a day | $2.63 on the 2-bottle pack, $2.30 on the 3-bottle pack, $1.63 on the 6-bottle pack |
| Money-back window | 60 days, counted from the day you pay. Start by phone (+1 (833) 762-2450) or by email, with your order ID |
Tracking
How can you track your feet over time?
Score your feet from 0 to 10 once a week, at the same time of day, and note sleep and anything new in your routine or medicines. Bring the log to your doctor.
If you try a supplement, start the log before the first capsule so you have a baseline.
FAQ
Frequently asked questions
Why do my feet tingle at night?
Possible causes include diabetes, low vitamin B12, alcohol, some medicines and infections. A doctor visit is the way to find yours.
How do I stop my feet tingling at night?
Find the cause first. Daily foot checks, steady blood sugar if you have diabetes and less alcohol all support nerve health.
Could metformin cause tingling feet?
Metformin might lower how much vitamin B12 the body absorbs, and low B12 can cause tingling. Ask your doctor about a B12 blood test.
When are tingling feet an emergency?
Sudden numbness or weakness on one side of the body, or sudden trouble speaking, seeing or walking. Call 911.
Do neuropathy supplements for feet work?
Some single ingredients show small gains in trials, mostly in people with diabetes. No supplement has been shown to repair nerves.
Is Quiet Nerves a treatment for tingling feet?
No. It is a dietary supplement, not a treatment for neuropathy, nerve pain or any disease, and it publishes no ingredient amounts.

Our view
Our view
Why do feet tingle at night? Often because a nerve signal is being scrambled, and the cause deserves a name before anything else.
Look at your feet daily, get the blood tests that fit, and keep supplements in their place: after the doctor and the daily basics. Quiet Nerves can only ever be that extra.
