Cortexi Review by a Tinnitus Specialist

As a tinnitus specialist, I’m troubled by how many of my patients have been burned by the Cortexi scam. Here’s what you’ll learn in this critical Cortexi review:

Does Cortexi Work? An MD Cortexi Review

Does Cortexi work as a tinnitus treatment? The short answer is no. Cortexi drops are being heavily marketed as a natural treatment for tinnitus to millions of people. In this review, I’ll explain why I believe that Cortexi is not effective. There is an urgent need for input from a trusted medical authority on whether Cortexi works for tinnitus. This Cortexi review is designed to provide a valid medical perspective for those considering purchasing Cortexi drops for tinnitus.

My name is Dr. Hamid Djalilian. I am a professor in the Departments of Otolaryngology, Neurosurgery, and Biomedical Engineering and am the Director of Otology and Neurotology at the University of California, Irvine. I’ve published over 300 articles on the ear and hearing and I’m internationally recognized as a tinnitus specialist. I am a doctor who teaches other doctors about tinnitus. I think it’s fair to say that I speak with high medical authority on the issue of whether Cortexi works for tinnitus.

What is Cortexi?

Cortexi is an herbal supplement in liquid form that you ingest orally, either under the tongue or mixed in a drink. Cortexi drops are supposed to “support hearing health”.

What does “Support Hearing Health” or “Ear Health” mean?

This is because the Cortexi supplement is bound by FDA and FTC laws that strictly govern what they (and other hearing supplements) can say about health benefits. They’re limited to descriptors like “promotes” or “helps” hearing health/ear health. They cannot say the Cortexi supplement is meant to “treat tinnitus” or “improve hearing health”. Other similar Cortexi supplement health claims include:

  • Promote hearing health
  • Support hearing function
  • Support brain function
  • Supports cognitive function
  • Support healthy hearing
  • Helps cognitive abilities
  • Supports auditory well-being

Fraudulent Cortexi Formula Claims

Despite strict laws against it, there are many fraudulent claims on the internet that the Cortexi formula treats tinnitus. If you look for Cortexi on Amazon, it is referred to as:

  • Cortexi Tinnitus Treatment
  • Cortexi Ear Drops for Tinnitus
  • Cortexi Tinnitus Relief

The Cortexi formula is classified as a dietary supplement and not a drug. The Dietary Supplement Health and Education Act (DSHEA) categorizes such supplements as foods rather than drugs, imposing restrictions on explicit health claims, especially for treating conditions like tinnitus

Consequently, Cortexi refrains from mentioning tinnitus on its official website and adheres to structure/function claims, highlighting its role to “support” hearing health/ear health, brain function, brain health, mental wellness, cognitive health, age related hearing loss, noise-induced hearing loss, and the like. These “health benefits” are within the legal constraints governing dietary supplements.

However, this has not stopped Cortexi drops from being advertised as a treatment for tinnitus.

Cortexi ear drops are surrounded by fraud and scandal. Cortexi is a scam

Cortexi’s Illegal Sales Strategy

Cortexi’s sales strategy uses a sophisticated affiliate marketing scheme to navigate around FDA regulatory constraints. While the company cannot make explicit health claims, affiliates associated with Cortexi employ strategic marketing tactics to promote the product as a “tinnitus treatment”, giving consumers exaggerated and misleading information far beyond supporting brain “ear health”. 

In addition to its claims about better hearing alone, Cortexi and affiliates go much further regarding “potential benefits”. You can find multiple claims about a variety of other benefits regarding brain function. For instance, Cortexi is supposed to improve cognitive function, memory, mental sharpness, brain fog, or other cognitive abilities. There are even claims that it improves longevity, fatigue the immune system, and libido.

This unethical approach allows Cortexi to advertise therapeutic benefits without violating explicit health claim regulations. At the same time, it creates a complex landscape for consumers to navigate when researching the product’s efficacy.

What are the Cortexi formula ingredients?

There are over 20 Cortexi formula ingredients, but the official website promotes eight as being particularly effective:  Grape seed extract, Green Tea extract, Gymnema Sylvestre, Capsicum Annuum, Panax Ginseng, Astragalus, Chromium Picolinate, and Maca Root. None of these natural ingredients can claim to treat tinnitus symptoms. The rest of the ingredients are “essential nutrients”.

On the product label, Cortexi’s natural ingredients are listed, but the exact levels of each ingredient is not. We’re only told that there is a total of 200mg of a “proprietary herbal blend” and around 2% of the daily value of chromium (0.7mcg). 

Table 1: Cortexi Ingredients, Health Claims, and Scientific Evidence.

IngredientClaimScientific Evidence 
Grape seed extractAntioxidants protect the earNo tinnitus evidence.
Green TeaImproves blood flow to the earsNo tinnitus evidence.
Gymnema SylvestreSupports HearingNo tinnitus evidence.
Capsicum AnnuumSupports healthy inflammationNo tinnitus evidence.
Panax GinsengNeuroprotective propertiesLimited poor evidence. 
AstragalusSupports clear soundsLimited poor evidence. 
Chromium PicolinateSupports auditory healthNo tinnitus evidence.
Maca RootBoost your energyNo tinnitus evidence.
This Cortexi review could find no evidence that Cortexi ingredients work for tinnitus.

Scientific Evidence of Cortexi Supplement Effects on Tinnitus

I went through each of the eight featured Cortexi ingredients to see if there was any scientific proof that these ingredients help treat tinnitus. I used the PubMed database and the National Library of Medicine (PubMed) for this research. My findings are summarized in the table below. 

For the most part, the featured ingredients in Cortexi have ZERO preclinical or clinical evidence when it comes to the treatment of tinnitus. For that matter, we no idea of the effect of the Cortexi formula on “ear health” or “auditory health”, such as its impact on inner ear hair cells, noise induced hearing loss, inner ear blood flow, ear infections, auditory perception, etc.

I found limited evidence on astragalus for tinnitus, but there were major problems. The studies on astragalus were conducted in the context of acute acoustic trauma to the inner ear, the astragalus was delivered in the form of an injection, and the preponderance of data was generated on guinea pig subjects. 

Cortexi scam ear drops have ginseng, but ginseng doesn't work for tinnitus.

I did find one human clinical trial of ginseng for tinnitus [1]. In this trial, there was a significant difference noted in the Tinnitus Handicap Index (THI) after 4 weeks of ginseng. However, there were several major problems with this study. 

  • First, the dose of ginseng used in this study was 3000mg. This is at least 15x higher than Cortexi’s ingredients. In the control group, they used 160mg of ginseng and in that group there was no effect. 160mg is closer to the amount of ginseng found in Cortexi drops. 
  • Second, even though the THI scores dropped in the high-dose ginseng group, the Visual Analog Score (VAS) score of subjective improvement did not change. In other words, the THI scores may have changed slightly, but the patients did not feel any better taking ginseng for tinnitus. 

Cortexi Dosage & How to Take Cortexi

The recommended Cortexi dosage is two droppers that you are instructed to take daily by mouth. This equates to 200mg of a “proprietary herbal blend” and 0.7 mcg of Chromium, according to the Cortexi label. Unfortunately, the amount of individual herbal supplements you take is impossible to determine because they’re listed together as a “proprietary blend”. 

Unlike prescription medications, supplement ingredients are not subject to strict FDA oversight. When FDA inspections do occur, they frequently reveal that supplement manufacturers neglect basic manufacturing standards, such as verifying the identity, purity, or composition of the final product. This lack of oversight highlights the variability and potential inconsistencies in dietary supplement formulations. 

I found no third-party verification of Cortexi ingredients, but some Cortexi reviews and complaints from the Better Business Bureau (BBB) suggest high variability in Cortexi ingredients. For instance, one consumer taking Cortexi noted: 

  • “When I received the new bottle, the product tasted totally different. That scared me and I called and emailed customer service. Ultimately I was informed that the ingredients in the new bottle may taste different?” 

This variability in Cortexi dosage and ingredients is highly concerning. Even if you know how to take Cortexi, you don’t know how much of its ingredients you are getting.

Cortexi Side Effects and Safety

There is very little information available on Cortexi side effects because it’s a dietary supplement and the regulatory reporting requirements are very lax. Some Cortexi supplement reviews by patients mention the following:

  • Upset stomach
  • Bloating
  • Nausea
  • Diarrhea
  • Headaches
  • Allergic reactions

I could not find any reports of serious adverse events on the FDA’s CFSAN Adverse Event Reporting System (CAERS) database. Note that this does not mean that adverse events have not occurred, just that Cortexi did not report any.

While not a side effect, one important warning is that numerous patients taking Cortexi report that the glass dropper was chipped or shatters. Obviously, ingesting broken glass can be a serious health hazard. 

Is Cortexi FDA approved?

No, Cortexi is not FDA approved.  On their own website they explain, “The information on this website has not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure or prevent any disease.”

However, part of the Cortexi scam is that the product is sold by affiliate websites. These sites get people to buy Cortexi and then get a kick-back portion of the sales. On these websites, false, misleading, inaccurate, and illegal claims are being made about Cortexi and tinnitus, including that Cortexi is “FDA approved”. 

Another Cortexi scam tactic is their claim that it’s made in an FDA registered facility. Even if this is true, the scam by Cortexi is the use of a “FDA registered facility” seal to give the impression that the FDA has approved the product. The unsuspecting buyer can see the FDA seal and easily be tricked into making this mistaken impression.

Is Cortexi FDA approved? No.

Is there Cortexi research on hearing health?

Cortexi research is basically non-existent. There is a complete lack of scientific evidence that the Cortexi formula works to prevent ear infections, help tinnitus or support hearing function. Despite this, the Cortexi website copy is filled with pseudoscientific claims and phrases. Here are some examples:

  • “Only research-backed, all-natural ingredients combined in the precise ratios“
  • “Engineered based on teachings of modern science”
  • “Gymnema Sylvestre is a clinically verified substance” 
  • “Panax ginseng is a scientifically established herb” 

Not only is there no scientific evidence to back their health claims, the claims themselves make no sense. For instance, what is a “clinically verified substance” or a “scientifically established herb”?

Scientific References for the Cortexi Formula

In addition, the Scientific References section on the Cortexi official website is a giant red flag. Shockingly, only 3 of the 35 articles listed have anything remotely to do with Cortexi research. Several articles had article titles without any reference attached. Some references on the list were duplicates. Some references had nothing to do with Cortexi drops, such as:

  • “Neurotoxicity of General Anesthetics”,
  • “Animal models for acute radiation syndrome”, or  
  • A Course in Miracles” (*this was my personal favorite*)

In short, there is a total lack of evidence that Cortexi works for tinnitus and its use of pseudoscientific language strongly suggests that Cortexi is a scam. 

Is Cortexi legitimate?

Cortexi is not a legitimate tinnitus treatment, even though many pages on the internet will lead you to believe that it is. There is no scientific evidence that Cortexi or any of its ingredients are effective in treating tinnitus. 

For all of these reasons outlined above, I have serious concerns about Cortexi’s legitimacy within the healthcare industry. Rather than operating as a transparent player, Cortexi relies on an intricate affiliate marketing scheme that hinders consumers’ ability to conduct thorough and reliable research through conventional channels. 

Is Cortexi a Scam?

MD Cortexi review reveals the Cortexi scam

The Cortexi Scam entails a network of affiliate marketers (think pyramid-like scheme) orchestrating a synchronized manipulation of internet search engines to deceive consumers into purchasing the product. 

As evidence of this, try doing a Google search for “Cortexi Scam”. Remarkably, every article retrieved using this search term (after personally examining over 50 websites) ultimately reveals itself to be an endorsement for the product.

The sophisticated nature of their marketing strategy creates obstacles in obtaining accurate and unbiased information about the product. This approach raises questions about the company’s commitment to transparency, ethical practices, and accountability within the healthcare sector. In short, I can make no other conclusion than Cortexi is a scam product. 

Cortexi Official Website

It’s exceedingly difficult to find the Cortexi official website. In fact, if you do a Google search of “Cortexi Official Website”, all you’ll find is a plethora of affiliate links purporting to be the official site. Many of these sites even have the Cortexi™ mark. I did this Google search myself and after counting 100 false sites, I gave up. 

This is all part of the scam to get people to buy Cortexi. These affiliate links actually feed back into the Cortexi sales funnel page or connect to the Cortexi sales team. However, because they are not the Cortexi official site, they can make fraudulent and illegal health claims. 

The actual official Cortexi website is getcortexi.com (or the mirror site trycortexi.com). You can tell because as opposed to all of the other affiliate sites, this site has a number of legal disclaimer pages that none of the fake sites have. Also, the support email address ends in @getcortexi.com. 

Imitation Cortexi Ear Drops 

One of the most baffling things about researching Cortexi ear drops is that there are scores of imitation Cortexi products being sold on Amazon. People trying to buy Cortexi are getting something completely different:

  • These products have completely different ingredients than the “official” Cortexi drops. 
  • The sham Cortexi dosage instructions are also different. 
  • Some Cortexi drops are actually oil drops where the user is directed to put them in the ear canal. 

These knock-off products bring the whole Cortexi scam to a new and frightening level. 

Cortexi Reviews and Complaints

cortexi reviews and complaints

It’s nearly impossible to find a legitimate Cortexi review because of the affiliate marketing scam has log-jammed search engines with false results. If you listen to Cortexi, it’s all positive reviews with no complaints. Verbatim from their website:

“Thousands of people enjoy taking Cortexi every day with great results and we have not received a single complaint yet.”

Thankfully, the Better Business Bureau (BBB), a consumer watchdog company, has published authentic Cortexi customer reviews and product complaints. Here are some REAL Cortexi reviews from REAL people taking Cortexi from the BBB website:

  • Richard H: “When tinnitus is so bad, you’ll try anything and, they know this… thus, the High Pressure Sales. Greed, plain and simple greed of the American dollar. I bet they don’t care about these important reviews and might even be joking right now about this, as they got their money on the backs of suffering people like me”
  • Christine K: “Complete and total hoax. This was an absolute waste of money. It’s really disgusting that scammers are willing to give people who are suffering hope. I wish I’d read real reviews before purchasing this worthless product. This business should be shut down. Please do not purchase this!”
  • Mirko P: “According to them, many of their customers noticed improvements in ear buzzing just after a week or two of using Cortexi! What a joke!!I purchased 3 bottles and after 3 months, not a slightest improvement in my ear buzzing! Once you report there’s no results and you want money back, customer service and support does not exist anymore! Such a waste of my money!!”
  • Gregg A: “I was fooled, too. On the video the salesman says, “I promise, you’ll see results in three weeks.” I noticed no difference in my tinnitus after 30 days using the product. Nothing. I sent in a request for a refund and received no reply. This is a bogus product, and they are likely making millions defrauding people who are desperate for results.”
  • Catheryn C: “DONT BUY THIS!! IMO this could be a dangerous product. Tracking this company is nearly impossible, the address is a suite, everything indicates that it’s made offshore and the scientist doesn’t appear to actually exist.”
  • Robert M: “It does not work as promised. No effect at all on tinnitus. Used for 60 days. Just another person/company getting wealthy on real people problems. Bad people ! Bad company!”
  • William L: “This Cortexi product is a scam! Do not fall for this gimmick! It does absolutely NOTHING to stop the ringing in your ears! If I could give it a zero star rating I would! Don’t fall for it!!!!!!!”

These BBB Cortexi reviews ring of deceptive sales practices, customer harassment, fraudulent claims, terrible customer service, and an ineffective product.

Trustpilot Cortexi Reviews

Another source of verified Cortexi reviews can be found on Trustpilot. As with the BBB, these reviews were nearly universally dismal with zero positive reviews. Here are some excerpts from people taking Cortexi on Trustpilot:

  • “Do your research before buying this rubbish. Don’t get ripped off like hundreds/thousands of other people!!”
  • “Cortexi is a complete scam. It does not work and the guarantee they offer is a scam as well.”
  • “Not only did my hearing and buzzing become much worse, but they did not give me a refund when I requested it.”
  • “Total Scam. I used it for 3 month religiously and zero improvement. Do not buy!!”
  • “Absolutely a slick slick con trick please don’t fall for it. It cost me a lot of money for nothing but sugar water syrup in a bottle. I am so mad at myself for falling for it.”
  • “I am a 70 year old lady, I did not have the money in the first place. But, the ringing in my ears is enough to make a person crazy. Cortexi, you should be ASHAMED”
  • “What a waste of money, but more importantly, it gave me hope where there was none. So sad…”
  • “Sadly, I now feel stupid for having spent my money on this product.”
  • “The company plays with your desperation to get tinnitus relief.”
  • “If I could give it a minus star, I would.”

It is heartbreaking for me to read these. There is anger, frustration, disappointment, and even shame and self-blaming in these reviews. As a physician with deep compassion for those suffering from chronic tinnitus, the Cortexi scam infuriates me. 

Cortexi Reviews and Complaints of Customer Harassment

Man shocked at the Cortexi scam

There have been multiple Cortexi complaints on BBB and Trustpilot of customer harassment. This comes in the form of aggressive upselling tactics, unapproved credit card charges, deceptive sales practices, return policy issues, and customer harassment and abuse. Here are some customer experiences from verified customers taking Cortexi:

Aggressive Cortexi Upselling

  • “I received a telephone call from a guy who identified himself as my “Cortexi Assigned Coach”. He had a pitch that he was assigned by Cortexi to make sure I had a good Cortexi experience. He said that for Cortexi to be effective, I basically had to purchase $1,300 of (two) supplemental products to help Cortexi eliminate my Tinnitus.”
  • “After placing an order, I instantly received phone calls from NewYork, NY trying to upsell me. They refused to cancel the order.”

Unapproved Cortexi Credit Card Charges 

  • “At the end of our conversation, they wanted to sell me something else! I said NO! They immediately hung up. Looking at my PayPal account, I realized that they charged me for an additional item.”
  • “Tried to purchase a 3 bottle deal from Cortexi, transaction refused by what I thought was the bank, turned out it was the representative from Cortexi, They called me, 28 minutes later, 6 bottles were billed” 
  • “They illegally charged my card an additional amount without my permission. In addition, 2 weeks later my card number was stolen”.
  • “I’ve started a fraud report with my credit card company. Today I started a case with our state attorney general.”

Deceptive Sales Practices by Cortexi 

  • “A shyster from an offshore call center called me. He was heavy-handed and offered me a $30 discount if I ordered through him. He claimed that I would have a 100% resolution of my tinnitus within the six month period of time just like he did.”
  • ”It didn’t work after a couple of weeks so I wrote to the company for a refund. They said I should give it at least 2 months to work, so I did. It still didn’t work so I asked for my refund. They said, “sorry, your 60 day period has expired.”
  • ”When I asked about the 100% guarantee, I was told to buy more and keep trying”

Problems Returning Cortexi

  • “I have had ZERO response from this company after 3 attempts to initiate a return and refund per their 60-Day Money Back Guarantee”.
  • “I sent that product back in July and it is now October. They are denying that they received the return.”
  • ”That is when I was told that to get the full refund, I had to return all the bottles that I had ordered, EVEN THE EMPTY ONES. Cortexi’s guarantee does not specify this.”

Phone Harassment and Abuse by Cortexi Staff

  • “I began to fill out the online form to purchase, and before I could even complete the form I started receiving phone calls from sales agents for the product – no less than three calls in five minutes.” 
  • “When I called about returning the product the woman hung up on me.”
  • “I was not seeing results and called Cortexi to find out how to return the product. Each time I called I was told “we have a poor connection. I can’t hear you”. I called Cortexi today and as with the other calls, they said “we have a poor connection; I can’t hear you”. I had been making business calls prior to her and after her with no issue.”

Cortexi Email Harassment

  • “I get marketing emails from them every day.”
  • “Once I ordered this product the amount of emails I received was unnerving. I’ve unsubscribed too many times to count and they still don’t stop. I attempted to contact the sender directly but it bounced back as an invalid email address and discovered it originated in Barbados.”

The BBB Cortexi Review

Aside from recording real customer complaints, the BBB also reviewed Cortexi in terms of deceptive and unethical marketing practices. Here are some highlights of the review:

ProblemBBB Notes
Money Back GuaranteeBBB has received multiple consumer complaints alleging that no full refunds have been provided.  
Fake EndorsementsThe business website is displaying the following seals: GMP Certified, FDA Seal, Made in the USA, 100% Natural ingredients, GMO Free. BBB could not locate information on the business website that substantiates the usage of these seals.
Scientific ReferencesThe page is displaying institutions’ seals as their scientific references (University of Glasgow, University of Leicester, Pubmed and Nature). BBB could not locate information on the business website that substantiates the usage of these seals.
False Claims“Its ingredients are scientifically proven to have medicinal properties that promote optimal ear health”:  BBB could not locate information on the business website about a clinical trial or studies conducted to scientifically prove the efficacy of this product. 
Fake Science“Thanks to its powerful compounds working together in synergy, Cortexi can enhance hearing significantly in just one week.”: BBB could not locate information on the business website about a clinical trial or studies conducted to scientifically prove the efficacy of this product. 
Misleading Information“Cortexi’s pharmaceutical manufacturing facility has obtained FDA approval.” BBB could not locate information on the business website about the FDA approved facility. 
Fake TestimonialsCustomer reviews speak about unsubstantiated health claims. The business website is displaying stock images as reviewers.
Negated ClaimsDisclaimer at the foot of the checkout page negates claims made throughout the website.   
The BBB’s scathing Cortexi review, resulting in a score of an F.

The BBB concludes their Cortexi review by stating, “Despite written requests, as of December 19, 2023, Cortexi has not responded to BBB’s request for revisions and clarification in its advertising”.   

Jonathan Miller and Tinnitus

Jonathan Miller tinnitus scientist doesn't exist, part of the Cortexi Scam

We are told that Jonathan Miller is the tinnitus “researcher” and “mastermind” who developed Cortexi. However, Jonathan Miller is not listed as an author on any of the 35 “scientific references” listed on the official Cortexi website.

In addition, there is no Jonathan Miller with any publications regarding tinnitus research, hearing health, the inner ear, noise induced hearing loss, age related hearing loss, ear hair cells, ear infections, or any other hearing related research that I could find in PubMed.

In the meantime, doing a Google search of “Jonathan Miller tinnitus” yields scores of fake affiliate marketing pages. Cortexi’s sophisticated strategy of dominating Google search results with deceptive sites makes it virtually impossible to find out any truthful or accurate information using standard internet research tools. 

I’m not the only one who had this problem. Several Trustpilot Cortexi reviews by product users had the same issue:

  • “When doing your research, see if you can find anything out about the founder of Cortexi, JONATHAN MILLER-I couldn’t!!!! Beware!!”
  • “First red flag is the guy presenting who calls himself ‘Jonathan Miller’. In one image he is wearing a doctor’s overall and stethoscope. I have conducted online searches to try to locate him as a registered doctor, without success so far. Google Image searches also fail to locate him. Who is he really?”
  • “The so-called ‘Doctor’ (ha!) Jonathan Miller is a total conman and he and his cronies should pay a price for what they do”

Do Cortexi ear drops work for tinnitus?

My medical opinion as a physician and tinnitus specialist is that Cortexi does not work for ear ringing. Why? Aside from the fact that Cortexi ingredients don’t work for tinnitus, chronic tinnitus is a complex neurological problem that involves dysfunctional neural networks in the brain.

All true tinnitus treatments must address the brain wiring problem if they are to provide lasting tinnitus relief. This requires a structured rehabilitation program that is multimodal in nature and requires sustained effort over a period of several months. The strategy of using an herbal tonic simply cannot accomplish this. 

If you need more proof, just consider some of these disappointing Cortexi reviews of actual users from Trustpilot and BBB:

  • “After 4 months of daily usage, my Tinnitus is as loud and intrusive as ever!”
  • “I finished the 6 months and there has been ZERO difference!!”
  • “Snake oil – I have been using this for almost 3 months and I must say that I am very disappointed that I haven’t received any relief from my tinnitus.”
  • “Cortexi did not work at all for my Tinnitus. That’s a zero star rating for the product.”
  • “Does not work! I tried this product for over 90 days, and absolutely NO improvement.”
  • “I’m 2 weeks in and nothing, sounds like the noise in my ear/brain is worsening”
  • “According to them, many of their customers noticed improvements in ear buzzing just after a week or two of using Cortexi! What a joke!! After 3 months, not a slightest improvement!”

Supplements for Hearing Health

I want to be clear that I routinely recommend vitamins and supplements as part of my tinnitus treatment program at NeuroMed. Natural remedies for tinnitus, when backed by evidence-based medicine and clinical trials, have a legitimate place in an integrative treatment strategy for tinnitus. 

Further, there is strong evidence that certain supplements do support auditory function, hearing health, help reduce noise induced hearing loss, slow age related hearing loss, protect hair cells in the inner ear, and effect blood circulation to improve blood flow to inner ear cells. Ironically, out of the universe of natural ingredients, Cortexi did not chose any of the ones with strong scientific proof.

However, the role of supplements for tinnitus or healthy hearing should always be complementary to other important interventions that bring about the brain rewiring that’s necessary for long-lasting tinnitus relief. 

One further caution, almost all herbal medicine formulations (like ginseng or ginkgo biloba) have extremely high variability in terms of the bioactive compounds included. You should always buy from the best sources if you’re going to take these.

Conclusion: Cortexi Scam or Legit?

In my medical opinion, Cortexi is a scam. As a tinnitus specialist with a background in otology and neurotology, I critically assessed the product. The key concerns include the lack of scientific evidence supporting Cortexi’s ingredients for tinnitus relief, dubious marketing practices, and the false claims of FDA approval. Reviews and complaints from users further emphasize its inefficacy, deceptive sales tactics, and poor customer service, harassment, and abuse. The Better Business Bureau (BBB) highlighted multiple issues, including unverified scientific references, false endorsements, and fake testimonials. Jonathan Miller, claimed to be the tinnitus researcher behind Cortexi, lacks any credible presence in tinnitus-related research. 

Sadly, there is no quick fix for tinnitus. Addressing chronic tinnitus requires a comprehensive, multimodal approach, and Cortexi’s herbal tonic falls short in providing a meaningful solution. Thus, the outcome of this Cortexi review is that it is a sophisticated scam that preys on vulnerable people suffering from tinnitus. Do not buy Cortexi!
