What Nerve Fresh is
Nerve Fresh is a capsule sold online for neuropathy, the burning, tingling, numbness or stabbing pain that comes from damaged nerves, usually in the feet and hands. Orders go through ClickBank. Each bottle holds 60 capsules, and the label serving is two capsules, so a bottle lasts a month, although the sales page that ClickBank customers see calls it “one easy daily capsule”. The site does not name the company behind it. Returns go to a fulfilment warehouse in Aurora, Colorado, that also handles other products sold through ClickBank.
What is in it
The Supplement Facts panel on the sales page lists, per two capsules:
- Passionflower (aerial parts) 350 mg
- Marshmallow root powder 220 mg
- Corydalis yanhusuo root extract (10:1) 200 mg
- Prickly pear cactus (nopal) powder 100 mg
- California poppy whole-plant extract 90 mg
That is all. Both sales pages say the formula also contains vitamins and minerals (“essential vitamin and mineral support”, in the words of nervefresh.com), but none is on the label, and one FAQ lists prickly ash bark, a different plant, instead of prickly pear.
What the evidence shows
- Corydalis: in 2014, researchers at the University of California, Irvine, found that a compound from the plant, dehydrocorybulbine, eased inflammatory and nerve-injury pain in mice. We found no trial of corydalis in people with neuropathy.
- Passionflower: a 2020 systematic review of nine short trials found that most reported less anxiety, but a Cochrane review of anxiety trials said they were too few to draw conclusions. The seller’s nerve-pain reference for it is a study in rats.
- California poppy: used traditionally as a sedative and sleep aid; we found no trial in neuropathy.
- Marshmallow root: a traditional remedy for sore throats and coughs; we found no nerve research in people.
- Prickly pear: studied as a food for blood sugar, in far larger amounts than the 100 mg here; we found no nerve research in people.
The sales pages cite a researcher’s faculty page, a zebrafish study of nerve damage from chemotherapy, a study of prickly pear juice as an antioxidant, a rat study of mulberry leaves, which are not in the product, a test-tube study of a plant compound in osteoarthritis, a university news story about the mouse study, a general review of diabetic neuropathy treatments whose summary does not mention these herbs, and passionflower studies in animals, anxiety and sleep. None tests an ingredient in people with nerve pain, and no study has tested Nerve Fresh itself.
For comparison, our neuropathy guide explains what does help: treating the cause, such as high blood sugar or a lack of vitamin B12, and medicines such as duloxetine, pregabalin and gabapentin, which reduce pain for some people.
Safety
- Drowsiness: passionflower, California poppy and corydalis are all used as calming or sleep aids. Together with gabapentin, pregabalin, sleeping pills, opioid painkillers or alcohol, they may add to drowsiness, and drowsiness plus numb feet raises the risk of falls. Ask your doctor or pharmacist before combining them.
- Do not stop gabapentin on your own: the US National Library of Medicine advises not stopping it without talking to your doctor, because stopping suddenly can cause withdrawal symptoms such as anxiety, sleeplessness, nausea, pain and sweating, and more seizures in people who take it for epilepsy.
- Liver: corydalis has been linked to liver injury; in a 2023 report, two people developed liver problems while taking a corydalis sleep aid, and their liver tests returned to normal after they stopped. Stop and see a doctor if you notice yellow skin or eyes, dark urine or unusual tiredness.
- The FAQ says there are no side effects. With three sedating herbs and a liver caution, that is not a claim we can support.
- See a doctor first: neuropathy can be caused by diabetes, low vitamin B12, alcohol, some medicines and other conditions, and treating the cause early may limit lasting damage. If your feet are numb, check them daily for cuts and sores.
What the sales pages claim
- Two doctors, one career: the sales page ClickBank customers see credits the formula to Dr. Mikel Daniels, a podiatric surgeon (DPM) with “26+ years in practice”; a podiatrist of that name is registered in Maryland. The company’s other site, nervefresh.com, credits the same formula and the same credentials, from a LifeBridge Health award to the first LEAP Center of Excellence in Maryland, to a “Dr. James Haleford”, a medical doctor from Temple University. We found no doctor of that name in the US national register of healthcare providers or on PubMed.
- “Ditch Gabapentin”: the written headline on the video sales page tells readers to drop the medicine. As above, stopping it suddenly can be harmful.
- Three “enzymes”: the sales page says the formula silences COX-2, PGE-2 and MMP-13, which it calls the real source of nerve damage. PGE2 is a prostaglandin, not an enzyme, and the MMP-13 research it cites was done in zebrafish given chemotherapy.
- Seals and logos: the page shows a USP Verified seal, but Nerve Fresh is not among the brands on USP’s own list of USP Verified products, and it shows Good Morning America, Esquire, USA Today and NBC logos under “Featured on” without saying what was featured.
- The refund policy refers to the product as “NeuroPure”, apparently copied from another product.
Price and refund
There is no single bottle. Two bottles cost $138 ($69 each), three cost $177 ($59 each) and six cost $234 ($39 each), all with free shipping; the three- and six-bottle packages add two e-books. It is a one-time payment, with no monthly charges. The refund window is 180 days from purchase, but read the conditions in the guarantee section below before ordering a large package. Our Nerve Fresh buying guide covers where it is sold and international shipping.
Realistic expectations
Nerve Fresh may make some people feel calmer or sleep better, given its herbs, but there is no evidence that it repairs nerves or eases neuropathy. A doctor can look for a treatable cause and discuss medicines that have been tested for nerve pain; if you take any of them, do not change them because of a supplement.

Choose Your Package
180-Day Money-Back Guarantee
The sales pages promise a refund within 180 days of purchase, “even if the container is completely empty”. The written refund policy adds conditions: you pay the return postage, the bottles must reach the returns warehouse in Aurora, Colorado, within the 180 days, and empty bottles are only accepted if enough time has passed to use them, so six empty bottles after one or two months would be refused. Email or call support first. Because the order goes through ClickBank, you can also contact ClickBank’s order support at clkbank.com. Keep your order number.
Frequently Asked Questions
Nerve Fresh is a capsule sold online for neuropathy symptoms such as burning, tingling and numbness. It is sold through ClickBank, and each bottle holds 60 capsules, a month’s supply at two capsules a day.
Per two capsules: passionflower 350 mg, marshmallow root 220 mg, corydalis root extract 200 mg, prickly pear cactus 100 mg and California poppy 90 mg. The label lists no vitamins or minerals, although the marketing mentions them.
It has never been tested. None of its herbs has a trial in people with neuropathy: a corydalis compound eased nerve pain in mice, and passionflower has been studied mainly for anxiety. The studies the seller cites are in animals, zebrafish or test tubes, or do not test its herbs.
Passionflower, California poppy and corydalis are sedating and may add to drowsiness from other medicines or alcohol, and corydalis has been linked to liver injury. The FAQ’s claim of no side effects is not something we can support. Ask your doctor first, especially if you take medicines for pain, sleep or epilepsy.
Ask your doctor or pharmacist first, because both can cause drowsiness. Do not stop gabapentin to take Nerve Fresh: stopping it suddenly can cause withdrawal symptoms, and more seizures in people who take it for epilepsy.
The site does not name a company. Its ClickBank sales page credits the formula to Dr. Mikel Daniels, a podiatrist, while nervefresh.com credits the same credentials to a Dr. James Haleford, whom we could not find in the US provider register. Returns go to a fulfilment warehouse in Aurora, Colorado.
It is a real product sold through ClickBank with a 180-day refund window and a published label. But its claims go far beyond the evidence, its sales pages name two different doctors with the same career, and its refund policy names another product.
There is no single bottle. Two bottles cost $138, three cost $177 and six cost $234, all with free shipping. It is a one-time payment.
You have 180 days from purchase. Email or call support, then send the bottles to the returns warehouse in Aurora, Colorado, at your own cost. The written policy accepts empty bottles only if enough time has passed to use them. ClickBank’s order support at clkbank.com can also help.

See Why Everyone's Choosing This →How we scored Nerve Fresh
Five weighted criteria — see our full methodology.
Whether the label discloses how much of each ingredient it contains, rather than hiding amounts inside a proprietary blend.
Whether the finished product has been tested in a published trial, or the claims rest on research into individual ingredients.
Monthly cost on the three-month package, the shortest course most vendors recommend (the single price for one-off digital products), compared against the rest of the category.
Length of the refund window measured against the trial period the vendor itself recommends.
How the product is sold: sales channel, checkout upsells, subscription defaults and how clearly the offer is presented.
Transparency is fair: a Supplement Facts panel on the sales page lists all five herbs with their amounts, but the marketing promises “essential vitamin and mineral support” that is not on it, one FAQ names prickly ash bark instead of prickly pear, and the site does not name the company behind the product. Evidence is weak: no ingredient has a human trial in neuropathy, the strongest results are for a corydalis compound in mice and for passionflower in anxiety, and none of the studies the seller cites tests an ingredient in people with nerve pain. Buying practices score at the bottom of the scale: the sales pages credit the same credentials to two different doctors, one of whom we could not find in the US provider register, a sales headline tells readers to “ditch gabapentin”, the FAQ says there are no side effects, the page shows a USP Verified seal although the brand is not on USP’s list, and the refund policy names a different product. In its favour, it is a one-time payment with a long refund window.
Final Verdict
Nerve Fresh publishes a label with the amount of each of its five herbs, which is more than many nerve supplements do. But none of those herbs has been tested in people with neuropathy: the best evidence is a corydalis compound that eased nerve pain in mice and passionflower studies in anxiety. The capsule itself has never been tested, and the vitamins and minerals the marketing mentions are not on the label.
The sales pages are the bigger concern. They credit the same career to two different doctors, tell readers to “ditch gabapentin”, and say there are no side effects, although three of the herbs are used as sedatives and corydalis has been linked to liver injury. Neuropathy has many causes, some of them treatable, such as diabetes and low vitamin B12, so see a doctor before trying a supplement, and never stop a prescribed nerve-pain medicine without your doctor’s advice.
