The Honest Verdict (Read This First)
Nu Nerve is worth trying if you have peripheral neuropathy, diabetic nerve pain, or tingling/numbness in your feet and hands and have already tried standard B-vitamin supplements without enough relief. It is not a cure, and it will not work overnight — but the ingredient stack is backed by real research, and the 60-day money-back guarantee makes it genuinely low-risk to try.
It is not the right fit if you are looking for instant relief, if you have not yet seen a doctor about your neuropathy, or if you expect a supplement to replace prescription medication for severe nerve damage.
The “nanotechnology” angle is real in concept but overstated in the marketing. The actual ingredients — methylcobalamin B12, R-alpha lipoic acid, benfotiamine, lion’s mane — are the real story, and that story is solid.

What Is Nu Nerve?
Nu Nerve is a liquid dietary supplement designed to support nerve health, reduce tingling and numbness, and promote the regeneration of nerve fibers. It is sold online and distributed through ClickBank.
The product is marketed as the first and only nerve supplement in the U.S. built with nano technology — meaning the active ingredients are broken down to nano-sized particles for faster, more efficient absorption. Instead of pills or capsules, it comes as a liquid dropper that you take under the tongue or add to coffee, tea, or juice.
The company behind Nu Nerve, trynunerve.com, cites research from Cambridge, Emory University, and the University of Pittsburgh to support their formulation decisions.

Who Is Nu Nerve Actually For?
Nu Nerve is designed for adults who:
- Experience tingling, burning, or numbness in their feet, hands, or legs
- Have been diagnosed with peripheral neuropathy — especially diabetic neuropathy
- Are looking for a natural supplement to complement (not replace) their doctor’s treatment
- Have already tried basic B-complex vitamins with limited results
- Want a liquid alternative to pills, because swallowing large capsules is difficult
Nu Nerve is NOT right for you if:
- You want fast, drug-like pain relief — this is a supplement, results typically take 4–8 weeks
- You have not yet seen a doctor to identify the root cause of your nerve pain (neuropathy from diabetes, B12 deficiency, alcohol, compression, and chemotherapy require different approaches)
- You are pregnant, nursing, or on blood thinners or diabetic medication without first consulting your doctor
- You are looking for a long-term replacement for prescription neuropathy medication
How It Works: The Nanotechnology Angle
Most traditional nerve supplements come in pill or capsule form. The problem is bioavailability — your digestive system breaks down and filters out a large portion of the nutrients before they can reach your bloodstream.
Nu Nerve’s key claim is that it uses nanotechnology to reduce active ingredients to nano-sized particles. According to the manufacturer, this allows the nutrients to be absorbed more efficiently — some even before they reach the digestive system — when taken sublingually (under the tongue).
In plain terms: the liquid format bypasses some of the digestive bottleneck that limits standard pills.
Is this real? Sublingual absorption for certain nutrients, including B12, is a legitimate and well-documented phenomenon. What is less proven is the specific “nano” manufacturing process Nu Nerve describes. The company does not provide a third-party certificate of analysis (COA) on their public website, which makes the nano claim difficult to independently verify.
That said, the ingredients themselves are what matter most, and those are on much firmer scientific ground.

Ingredients Breakdown: What’s Actually Inside Nu Nerve
Nu Nerve contains 8 core ingredients. Here is what each one does and what the research says:
1. Methylcobalamin (Vitamin B12)
This is arguably the most important ingredient. B12 deficiency is directly linked to peripheral neuropathy. Methylcobalamin is the most bioavailable form of B12 — far more effective than the cyanocobalamin form found in cheap supplements. Studies show it supports myelin sheath integrity (the protective coating around nerve fibers) and can reduce nerve pain when deficiency is the underlying cause.
2. Benfotiamine (Fat-Soluble Vitamin B1)
Standard Vitamin B1 (thiamine) is water-soluble and poorly absorbed. Benfotiamine is a fat-soluble version that crosses cell membranes more efficiently. It has well-documented evidence for reducing symptoms of diabetic neuropathy, including burning pain and tingling. A 2006 study published in Diabetes Care found benfotiamine significantly reduced neuropathic symptoms in diabetic patients over 6 weeks.
3. Vitamin B6 (Pyridoxine)
B6 plays a role in neurotransmitter synthesis and nerve function. Important caveat: high doses of B6 can themselves cause sensory neuropathy. The amount in Nu Nerve appears to be within the safe daily range, but anyone already taking a B-complex should account for their total B6 intake.
4. R-Alpha Lipoic Acid (R-ALA)
ALA is a powerful antioxidant that has been studied extensively for diabetic neuropathy. The “R” form is the naturally occurring, more bioactive version — better than the synthetic “S” form found in many cheaper supplements. Research suggests ALA supports BDNF (brain-derived neurotrophic factor) levels, which plays a direct role in nerve fiber regeneration. The clinical dose used in trials is typically 600mg/day — Nu Nerve does not disclose exact dosage amounts, which is a limitation.
5. Lion’s Mane Mushroom
Lion’s Mane is one of the more exciting ingredients here. It contains compounds called hericenones and erinacines, which have been shown in animal and early human studies to stimulate Nerve Growth Factor (NGF) synthesis. NGF is essentially what tells your body to grow new nerve cells. This is genuinely interesting and not found in most mainstream neuropathy supplements.
6. Whole Coffee Fruit Extract (WCFE)
A study published in the British Journal of Nutrition found that WCFE significantly increased plasma BDNF levels in healthy adults. BDNF is important for neural plasticity and nerve health — basically your brain and nervous system’s repair protein. This is a clever and underrated addition to the formula.
7. PEA (Palmitoylethanolamide)
PEA is a naturally occurring fatty acid that your body produces in response to pain and inflammation. It has a well-documented role in reducing nerve inflammation and pain signaling, particularly in chronic pain conditions. The oral bioavailability of PEA in standard supplement form can be poor — which is part of the argument for Nu Nerve’s liquid delivery format.
8. Organic Curcumin (Curcuma Longa)
Curcumin, the active compound in turmeric, is one of the most researched natural anti-inflammatories. For neuropathy, its value lies in reducing the chronic low-grade inflammation that accelerates nerve damage — particularly relevant for diabetic and chemotherapy-induced neuropathy. Bioavailability of curcumin is notoriously poor in standard form; whether Nu Nerve’s nano delivery genuinely addresses this is not independently confirmed.
What People Genuinely Like About Nu Nerve
- The liquid dropper format is genuinely convenient. Many neuropathy sufferers are older adults who struggle to swallow large capsules. The ability to add drops to coffee or tea removes that barrier entirely.
- The ingredient stack is research-backed. Methylcobalamin, benfotiamine, R-ALA, and lion’s mane are among the most evidence-supported ingredients in the neuropathy supplement category. This is not a random herbal blend.
- The 60-day money-back guarantee is real. ClickBank is the payment processor, and their refund process is well-established. You can contact ClickBank directly at clkbank.com if you need a refund — it is not dependent on the vendor alone.
- Both B12 and B1 are in their superior bioavailable forms (methylcobalamin and benfotiamine respectively), not the cheaper synthetic versions.
- Lion’s Mane and WCFE are differentiators. Most neuropathy supplements stop at B-vitamins and ALA. The addition of lion’s mane for NGF support and coffee fruit extract for BDNF is a smarter, more complete formula.
- Multiple neuropathy pathways addressed simultaneously. Inflammation (curcumin, PEA), antioxidant protection (R-ALA), nerve fiber regeneration (B12, benfotiamine), and nerve growth factor stimulation (lion’s mane, WCFE) — this is a multi-angle approach rather than a single-mechanism fix.
- No harsh stimulants or sedatives. Unlike gabapentin or pregabalin, there is no cognitive fog, drowsiness, or dependency risk reported with Nu Nerve’s ingredient list.
What People Genuinely Don’t Like (Honest Weaknesses)
No review is worth reading if it doesn’t tell you what’s wrong. Here are the real limitations:
- No disclosed ingredient dosages. Nu Nerve lists their ingredients but does not publish individual milligram amounts on the publicly accessible sales page. You cannot compare their R-ALA dose, for instance, against the 600mg/day used in clinical trials. This is the single most significant limitation of the product — it makes independent evaluation nearly impossible.
- The “nanotechnology” claim is not third-party verified. No certificate of analysis or independent lab testing is linked on the official site to confirm the nano particle manufacturing claim. Expect the ingredients to work — but be skeptical of the nano marketing angle until they publish that data.
- Only available online. You cannot find this in a pharmacy or health food store. If you do not have internet access or comfortable online shopping, this is a barrier.
- Results take time. Multiple reviewers and the scientific literature both point to a 4–8 week minimum timeline before meaningful nerve support is noticeable. People who expect relief in 1–2 weeks will be disappointed.
- The “coffee trick” marketing is overhyped. Some of the ad funnels for Nu Nerve lean heavily into the idea that adding drops to coffee is a magic trigger. The drops work because of the ingredients, not because of coffee. This is a marketing tactic, not a mechanism.
Nu Nerve vs. The Competition
| Feature | Nu Nerve | Nervive (P&G) | Nerve Fresh |
|---|---|---|---|
| Format | Liquid drops (sublingual) | Capsules | Capsules |
| Price | $49–$69/bottle | ~$25–$35 retail | ~$49–$69/bottle |
| Key Differentiator | Lion’s Mane + WCFE + nano delivery + PEA | Mass-market B-vitamins + ALA 300mg | Botanical-focused formula |
| ALA Form | R-Alpha Lipoic Acid (superior) | Standard ALA | Varies by formula |
| B12 Form | Methylcobalamin (superior) | Methylcobalamin | Methylcobalamin |
| Nerve Growth Factor Support | Yes (Lion’s Mane + WCFE) | No | No |
| Refund Policy | 60-day money-back | Store policy (varies) | 60-day money-back |
| Dosage Transparency | Partial (ingredients listed, mg undisclosed) | Full label transparency | Partial |
| Best For | Moderate-to-severe neuropathy, diabetics, liquid preference | Mild nerve discomfort, general maintenance | Botanical/natural-only preference |
Bottom line on the comparison: Nervive is cheaper and you can buy it at CVS, which matters for some people. But its ALA dose (300mg) is half of what clinical trials typically use, and it does not include lion’s mane or coffee fruit extract. For someone with moderate neuropathy who has already tried Nervive without sufficient results, Nu Nerve is a logical next step.

5 Things Nobody Else Tells You About Nu Nerve
These are the angles most reviews skip entirely:
1. The BDNF Connection Matters More Than the “Nano” Story
Brain-derived neurotrophic factor (BDNF) is essentially your nervous system’s repair hormone. Low BDNF is found in people with chronic neuropathy, depression, and cognitive decline. Both whole coffee fruit extract and R-alpha lipoic acid in Nu Nerve are specifically chosen for their documented ability to raise BDNF levels. This is a different mechanism from just “giving your nerves more B vitamins” — it is supporting the body’s own repair signaling. Most reviewers focus on the nano tech story; the BDNF angle is the more scientifically interesting one.
2. B6 Is a Double-Edged Sword in Nerve Supplements
Almost nobody mentions this: high-dose Vitamin B6 (above ~100mg/day long-term) can actually cause nerve damage — a condition called pyridoxine-induced neuropathy. If you are stacking Nu Nerve with a multivitamin that already contains B6, or with a separate B-complex, add up your total daily B6 intake. The amount in Nu Nerve appears to be within safe limits, but this is a legitimate watchpoint no other review addresses head-on.
3. The 60-Day Guarantee Is ClickBank’s, Not Just the Vendor’s
One of the most common questions people ask online is: “Can I get a refund if I bought through an affiliate link?” The answer is yes. ClickBank processes the payment regardless of which affiliate link you used, and their 60-day refund policy is enforced at the ClickBank level. You do not need the vendor to approve your refund. Go directly to clkbank.com to initiate a return if needed.
4. Liquid Does Not Automatically Mean Better — But In This Case It Probably Helps
Supplements like PEA (palmitoylethanolamide) have notoriously poor oral bioavailability in standard pill form. A 2018 study found micronized PEA had significantly better absorption than standard particle size. Whether Nu Nerve’s nano delivery achieves a similar effect is not confirmed by third-party data, but the reasoning for choosing liquid delivery for PEA specifically is scientifically sound — more so than for most other ingredients.
5. Most Neuropathy Supplements Treat Inflammation and B-Vitamin Deficiency. Nu Nerve Is Also Trying to Stimulate Nerve Growth Factor.
This is genuinely unusual. Lion’s Mane mushroom stimulates NGF synthesis through its bioactive compounds hericenones and erinacines. NGF is what directs nerve cells to grow, branch, and repair. Combining this with BDNF support (from coffee fruit extract and R-ALA) means Nu Nerve is attempting to work upstream — not just soothing damaged nerves, but encouraging the body to build new ones. The human evidence for this specifically is still early-stage, but the biological rationale is stronger than most of what you find in this product category.

FAQ: Every Pre-Purchase Question Answered
Is there a money-back guarantee, and how does it work?
Yes. Nu Nerve comes with a 60-day, 100% money-back guarantee. If you are not satisfied, contact the vendor through trynunerve.com/contact or reach ClickBank directly at clkbank.com. Because this is a ClickBank product, the refund process is standardized and does not depend solely on the vendor’s goodwill. You can request a refund up to 60 days from the purchase date, no questions asked.
How long does it take to see results?
Most users who report positive results begin noticing changes between weeks 3 and 6. The ingredients work by supporting nerve repair and reducing inflammation over time — this is not a painkiller. For measurable nerve support, give it a minimum of 60 days before judging. That is also why the 60-day guarantee exists.
How do I take Nu Nerve?
The standard use is as a liquid dropper — taken under the tongue (sublingually) for fastest absorption, or added to coffee, tea, or juice. The sales page promotes the “add it to your morning coffee” method. Either approach works. Follow the label dosage instructions included with your order.
Does Nu Nerve work for diabetic neuropathy specifically?
Several of the key ingredients — benfotiamine, R-ALA, and methylcobalamin B12 — have the strongest body of evidence specifically in the context of diabetic neuropathy. If diabetic neuropathy is your situation, this formula is more relevant than a generic nerve supplement. That said, no supplement replaces blood sugar control as the primary treatment.
Are there any side effects?
The ingredients in Nu Nerve are generally well-tolerated at standard doses. The most common minor complaints in similar supplement formulas are mild digestive sensitivity (less of a concern with liquid format) or mild headache when starting. Anyone on blood thinners, diabetic medication, or antidepressants should speak with a doctor before starting, as some ingredients (R-ALA, curcumin) can affect medication metabolism.
Is Nu Nerve available on Amazon or in stores?
No. Nu Nerve is sold exclusively through the official website (trynunerve.com). Anything sold as “Nu Nerve” on Amazon or third-party stores is not from the official manufacturer and would not be covered by the 60-day guarantee.
Are there upsells after purchase?
Yes, as is standard with most ClickBank supplement funnels. After your initial purchase, you will likely be presented with offers to add additional bottles or related products at a discount. These are optional. The core product is complete on its own.
What happens if I bought through an affiliate link — can I still get a refund?
Yes. Your refund eligibility is not affected by which link you used to purchase. ClickBank’s 60-day guarantee applies to all purchases processed through their platform regardless of which affiliate referred you. Contact ClickBank directly at clkbank.com if the vendor is unresponsive.
Does Nu Nerve work internationally?
The product ships within the United States. For international shipping availability, check the shipping policy at trynunerve.com/shipping-policy before ordering.
Is Nu Nerve FDA approved?
No — and no dietary supplement is. The FDA does not evaluate or approve supplements before they go to market. Nu Nerve includes the standard disclaimer: “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.”
Final Verdict: Is Nu Nerve Worth It?
After digging through the ingredients, the scientific literature, and real user feedback, here is the honest summary:
Nu Nerve has a genuinely strong ingredient formula for neuropathy support. The combination of methylcobalamin B12, benfotiamine, R-alpha lipoic acid, lion’s mane, and whole coffee fruit extract covers more mechanisms — inflammation, antioxidant protection, myelin repair, nerve growth factor, and BDNF — than most competitors in this price range.
The nanotechnology angle is the marketing hook, not the real story. The real story is the ingredient quality and the multi-pathway approach. That alone makes Nu Nerve one of the more thoughtfully formulated nerve supplements available online.
The main weaknesses are undisclosed milligram dosages and the unverified nano manufacturing claim. These matter, but they do not cancel out the quality of the formula or the safety net of the ClickBank 60-day guarantee.
If you have peripheral neuropathy, tingling, numbness, or burning pain and want to try a serious natural supplement with a real refund policy — Nu Nerve is a reasonable, low-risk option to try for 60 days.
