Nerve Savior Side Effects and Who Should Ask First
Most possible Nerve Savior side effects are mild, such as nausea, cramps or loose stools.
Headache or dizziness can also happen. Ginkgo may raise bleeding risk with blood thinners, and green tea extract and too much vitamin B6 over time carry rarer risks.

The short version
What are the side effects of Nerve Savior?
The most likely side effects are stomach-related and mild: nausea, cramps, loose stools or dry mouth. Headache and dizziness are also possible. These come from the ingredient research, because no trial of Nerve Savior has been published.
A few rarer risks deserve more attention. With blood thinners, ginkgo may add to bleeding risk (NCCIH, Ginkgo). Green tea extract has been linked to rare liver injury (LiverTox, Green Tea). And vitamin B6, taken in excess for a long time, can itself damage nerves (ODS, Vitamin B6).
The doses are probably small, since 11 ingredients share 600 mg. Still, "natural" does not always mean safe (NCCIH, Using Supplements Wisely).
Ingredient by ingredient
Which Nerve Savior ingredients can cause side effects?
Each of the 11 has its own profile. Below, known effects from government sources sit next to each ingredient's label-math ceiling.
| Ingredient | At most | Reported side effects or cautions |
|---|---|---|
| Himalayan pink salt | 600 mg | Adds about 22-240 mg sodium; matters on a low-salt diet (CDC, Sodium) |
| Cinnamon extract | 300 mg | Coumarin in cassia cinnamon linked to liver effects (NCCIH, Cinnamon) |
| AGP choline (alpha-GPC) | 200 mg | At high intakes: fishy body odor, sweating, low blood pressure (ODS, Choline) |
| Bacopa monnieri | 150 mg | Nausea, cramps, loose stools, dry mouth (LiverTox, Bacopa) (StatPearls, Bacopa) |
| Lutein | About 6 mg | No specific warning in the sources we checked (NEI, AREDS/AREDS2) |
| Bilberry leaf | 100 mg | Leaves may be unsafe in high doses or long-term use (NCCIH, Bilberry) |
| Vitamin B6 | About 86 mg | Long-term excess can cause numbness and poor coordination (ODS, Vitamin B6) (MedlinePlus, Vitamin B6) |
| Ginkgo biloba | 75 mg | Dizziness, stomach upset, headache; bleeding risk with blood thinners (NCCIH, Ginkgo) |
| Vitamin B12 | About 667 mcg | No upper limit set (ODS, Vitamin B12) |
| Zeaxanthin | About 3 mg | No specific warning in the sources we checked (NEI, AREDS/AREDS2) |
| Green tea extract | 54.5 mg | Caffeine; rare liver injury, usually 1-6 months in (NCCIH, Green Tea) (LiverTox, Green Tea) |
The B6 point
Can the vitamin B6 in Nerve Savior cause tingling?
It can if your total B6 intake stays too high for too long. Large doses of B6 cause numbness, sensory changes and trouble coordinating movement, the very symptoms many buyers want to ease (MedlinePlus, Vitamin B6).
The label hides the B6 amount inside the blend. Its ceiling is about 86 mg a day. That is below the U.S. upper limit of 100 mg, but the European Food Safety Authority set a 12 mg adult limit in 2023 after reviewing neuropathy reports (ODS, Vitamin B6). The adult need is only 1.3 to 1.7 mg (ODS, Vitamin B6). The National Institute of Neurological Disorders and Stroke lists excess B6 as a known vitamin-related cause of neuropathy (NINDS, Peripheral Neuropathy).
Multivitamins, B-complex pills and other nerve formulas often contain B6. Add them up with your pharmacist. If tingling gets worse after starting Nerve Savior, stop and tell your doctor.
Medicines
What medications interact with Nerve Savior?
Blood thinners, nadolol and atorvastatin have documented interactions with its ingredients. Several other medicines and conditions call for a check with your doctor first.
| Medicine or situation | Ingredient involved | What may happen | What to do |
|---|---|---|---|
| Warfarin or other anticoagulants; antiplatelet drugs | Ginkgo | Higher bleeding risk; bleeding reports exist (NCCIH, Ginkgo) (LiverTox, Ginkgo) | Ask your prescriber before starting |
| Nadolol (beta-blocker) | Green tea extract | Lower nadolol levels (NCCIH, Green Tea) | Ask your prescriber |
| Atorvastatin (statin) | Green tea extract | Lower atorvastatin levels (NCCIH, Green Tea) | Ask your pharmacist |
| Diabetes medicine | Cinnamon extract | Unclear effect on blood sugar (NCCIH, Cinnamon) | Check with your provider; keep monitoring |
| Metformin, PPIs or H2 blockers | Vitamin B12 | These drugs lower B12; a supplement does not replace testing (ODS, Vitamin B12) | Ask for a B12 blood test |
| Other B6 supplements | Vitamin B6 | Total B6 may climb too high (ODS, Vitamin B6) | Add up all B6 sources |
| Low-sodium diet | Himalayan pink salt | Extra sodium every day (CDC, Sodium) | Count it in your daily total |
| Planned surgery | Ginkgo | Supplements may raise bleeding risk around surgery (NCCIH, Using Supplements Wisely) | Tell your surgeon well ahead |
Supplements should never replace prescribed medicine, the FDA says (FDA 101, Supplements). Read more in our post on B12, metformin and tingling feet.
Who should skip it
Who should avoid Nerve Savior?
Children and teens should not take it; the label says "Adult Use Only". Several adults should get a doctor's okay before the first capsule.
- Anyone under 18.
- Pregnant or nursing mothers (the label asks them to consult a physician).
- People on blood thinners, nadolol, atorvastatin or diabetes medicine.
- Anyone with liver disease or a past reaction to green tea extract.
- People told to limit sodium for blood pressure, heart or kidney reasons.
- Anyone already taking high-dose B6 or a B-complex.
Warning signs
When should you stop Nerve Savior and call a doctor?
Stop right away if you notice signs of bleeding, liver trouble or worsening nerve symptoms. Then call your doctor and bring the bottle.
Unusual bruising, nosebleeds, bleeding gums or black stools. Yellow skin or eyes, dark urine or pain under the right ribs. Tingling, numbness or clumsiness that is new or getting worse. A rash, swelling or trouble breathing needs emergency care.
For an upset stomach or headache that does not pass, stop the capsules. Never take extra capsules to "catch up" on a missed day.
Keep one more thing in mind. Numbness, tingling or burning in the feet can signal diabetes, low B12 or another condition. Checking your feet daily and seeing a doctor promptly matters more than any supplement (CDC, Diabetes & Feet).

Five quick questions show whether to talk to a doctor before ordering.
FAQ
Nerve Savior side effects: common questions
Does Nerve Savior have side effects?
It can. No trial of the product exists, but its ingredients have known effects: bacopa can cause nausea and loose stools, ginkgo can cause headache and dizziness, and green tea extract contains caffeine. Most are mild at small doses. Stop and call a doctor if anything feels wrong.
Can Nerve Savior cause tingling or numbness?
Possibly, through its vitamin B6. Too much B6 over months can cause numbness and poor coordination. Nerve Savior's B6 is capped at about 86 mg a day but not printed, so if tingling starts or worsens after you begin, stop and tell your doctor.
Is Nerve Savior safe with anticoagulants like warfarin?
Only with your doctor's approval. Nerve Savior contains ginkgo, which may raise bleeding risk with anticoagulants such as warfarin and with antiplatelet drugs. Your prescriber can judge the risk and decide whether extra monitoring is needed.
Is Nerve Savior safe for diabetics?
Ask your doctor first. The blend includes cinnamon extract, and it is unclear whether cinnamon affects blood sugar. If you take metformin, ask for a B12 blood test too. Keep your diabetes treatment and daily foot checks going; Nerve Savior does not replace them.
Is Nerve Savior bad for your liver?
Liver problems are rare but possible. Green tea extract pills have been tied to liver injury, usually 1 to 6 months after starting, and cassia cinnamon contains coumarin. People with liver disease should ask a doctor first. Yellow skin or dark urine means stop and call.
How do I report a bad reaction to a supplement?
Report it to the FDA through MedWatch, its safety reporting program, after you get medical care. Include the product name, the label, when you started and your other medicines. Also tell your doctor and the seller so the order can be handled.
Can you take Nerve Savior while pregnant?
Not without your doctor's approval. The label tells pregnant or nursing mothers to consult a physician before using it. Bring the bottle to your obstetrician so they can review all 11 ingredients and your other prenatal supplements.
