Short answer: NervoLink is a capsule blend of nine mushrooms, including reishi, lion's mane and cordyceps. One bottle costs $69 officially; larger packs show no price in text. Some of these mushrooms may lower blood sugar or raise bleeding risk.

What is NervoLink?

NervoLink is a dietary supplement sold through its official website and marketed for nerve support. According to the official website, it comes as capsules made in the USA and sold in bottles in 30-, 90- and 180-day supplies.

Unlike the herbal and vitamin formulas we cover elsewhere, NervoLink is built entirely on medicinal and culinary mushrooms. That makes it an interesting option for people who already use mushroom supplements, but it also raises a specific safety question for people with diabetes, which we explain below.

The sales page uses a headline about stopping neuropathy. We do not repeat that kind of promise: no supplement is proven to stop, treat or reverse neuropathy, and nerve symptoms deserve a medical evaluation first.

What mushrooms are in NervoLink?

According to the official website, NervoLink contains:

The page does not list the amount of each mushroom, the type of extract or the part of the mushroom used. Those details change a lot from one product to another.

What does the research say about the NervoLink mushrooms?

Mushroom supplements are popular, but human research on nerve health is early. Here is what Memorial Sloan Kettering Cancer Center's "About Herbs" database, a well-regarded clinical reference, says about several of them:

• Lion's mane. MSKCC says lion's mane is used to improve memory and mood and to reduce stress, and that these uses have not been fully studied. Possible side effects include stomach discomfort, nausea and skin rash. Lab research on lion's mane and nerve growth factors is often cited in marketing, but that is not the same as proof in people.
• Reishi. MSKCC lists immune and stamina uses, with possible side effects of nausea, insomnia and, rarely, liver injury. It warns that reishi may increase bleeding risk with blood thinners such as warfarin.
• Cordyceps. MSKCC notes cordyceps may lower blood sugar, so people on insulin or other glucose-lowering drugs should talk with their provider. It may also increase bleeding risk with blood thinners.
• Turkey tail (coriolus). MSKCC reports dark stools and darkened fingernails as possible side effects, and says its safety in pregnancy is unknown.
• Shiitake. MSKCC describes mixed results from small studies of shiitake extracts and lists skin reactions among possible side effects.

None of these sources describes any of these mushrooms as a treatment for neuropathy, and we found no study of the NervoLink formula itself.

Is NervoLink safe for people with diabetes?

This is the key question for many readers, since diabetes is the leading cause of neuropathy. Cordyceps may lower blood sugar, according to MSKCC. Adding it on top of insulin, sulfonylureas or other diabetes medicines could, in theory, push glucose too low. That does not mean NervoLink is off-limits, but it does mean you should talk with your doctor first and check your glucose more often if you start.

How much does NervoLink cost?

On the official website (checked 2026-10-08), the 30-day supply of one bottle is listed at $69 as a one-time fee. The 90-day (three bottles) and 180-day (six bottles) packages are offered at a discount, but their prices were not shown in the page text, so check the current price on the official website. All packages list free US shipping; international orders pay shipping fees.

Does NervoLink have a money-back guarantee?

The guarantee length is not stated in the page text we read. The page links to a refund policy. Read it before you buy, and confirm the deadline and return steps at checkout.

What does the official page say about manufacturing?

The page makes an approval claim involving the FDA about its manufacturing facility and calls it GMP certified, while the same page carries the standard disclaimer that its statements have not been evaluated by the FDA. Those two statements do not sit well together. For clarity: the FDA does not approve dietary supplements or supplement products before sale, so read any approval claim as marketing and confirm details with the seller.

Who might consider NervoLink?

• Adults who already use mushroom supplements without problems.
• People who have seen a doctor about their nerve symptoms and want a wellness add-on.
• People who are not on blood thinners or glucose-lowering medicine, or whose doctor has approved it.

Who should avoid NervoLink or ask a doctor first?

• People taking warfarin or other blood thinners (reishi and cordyceps may increase bleeding risk).
• People on insulin or other diabetes medicines (cordyceps may lower blood sugar).
• People taking immunosuppressants, according to MSKCC's reishi entry.
• Pregnant or breastfeeding women, and anyone under 18.
• People with mushroom allergies or liver disease.
• Anyone with surgery coming up.

What are the downsides of NervoLink?

• Limited disclosure: no doses, extract ratios or mushroom parts in the page text.
• Prices for multi-bottle packs not in text, and no guarantee length on the page itself.
• Conflicting manufacturing claims (see above).
• Interaction risks that matter most to the people most likely to buy it.
• No trials of the formula.
