Our verdict on Cerebrozen
What we liked
- The vendor publishes its Supplement Facts label, so you can check it before buying.
- It is a liquid dropper, so there are no pills to swallow.
- There is a 60-day refund window, and ClickBank offers a third-party refund route.
- Free US shipping showed on the 3 and 6 bottle checkouts.
Watch out for
- Six of the eight ingredients the sales page names are not on the label.
- No label ingredient has human evidence for tinnitus or hearing.
- A 200 mg proprietary blend hides every individual dose.
- The label says "Ketone Liquid Drops" and reads like an energy and weight-loss blend.
- It contains guarana and green tea (caffeine sources) despite a "No Stimulants" claim, plus licorice glycyrrhizin.
- Refunds need an approved RMA, you pay return postage, and shipping and handling is kept.

Cerebrozen is a liquid dropper sold as a hearing support formula, and the label on the vendor's own site does not match the ingredients its sales page advertises.[1][2] The sales page names eight hearing ingredients; the Supplement Facts panel lists a 200 mg proprietary blend of 22 items such as guarana, African mango and raspberry ketones. Six of the eight advertised ingredients do not appear on it.
We read the label, the sales pages, the refund policy and three ClickBank checkouts, then compared the ingredients against published research. Our method is on the how we check products page. Prices and terms below were checked October 19, 2026.
What is Cerebrozen and what does the vendor claim?
The vendor also says users "will notice less noise and better ear health" once the body adapts, and that "Most people start feeling a difference after the first week." Those are sales claims, and no study of the finished product backs them.
The label lists a 1 ml serving and 30 servings per bottle.[2] The main order page sells through ClickBank, which appears on your card statement as CLKBANK*CerebroZen.[1] A second vendor page sends buyers to a BuyGoods checkout instead.[3] The distributor is listed as cerebrozen.com at a private mailbox in Miami, Florida, and the creator is named only as "Daniel Lopez", with no credentials given.[4]

Who might consider Cerebrozen, and who should not?
Cerebrozen fits only an adult with no medical conditions who wants to try a low-dose energy-style blend and accepts that no evidence ties it to hearing. Anyone with new, one-sided or worsening tinnitus should see a doctor or audiologist first, because ringing can signal hearing loss or other conditions that need a proper check.[10]
The label itself says pregnant or nursing women, anyone under 18 and anyone with a known medical condition should ask a physician before use.[2] Skip it, or ask your doctor first, if you:
- take blood pressure, diabetes, blood-thinning or heart medicines;
- take a drug that carries a grapefruit warning, such as some statins;[15]
- have high blood pressure, heart or kidney disease (licorice glycyrrhizin);[14]
- are sensitive to caffeine, since guarana and green tea are both on the label.
A supplement is not a substitute for a hearing test. The tinnitus guideline from the American Academy of Otolaryngology starts with an ear exam and a hearing evaluation.[9]
How does Cerebrozen claim to work?
The vendor says Cerebrozen works through blood flow and antioxidants: "Vinpocetine Supports blood flow to the ears", "Lion's Mane Powder Supports hearing" and "Lemon Extract Antioxidants protect the ear".[1] Vinpocetine and lion's mane are not on the label, so that part of the mechanism cannot apply to the bottle as labeled.[2]
The vendor also calls the formula "research-backed" and says the ingredients are combined "in the precise ratios required to support healthy hearing". The ratios are hidden inside a proprietary blend, so a buyer cannot check them.
What the label does list is a different kind of product. Guarana, green tea, African mango, raspberry ketones, coleus forskohlii and capsicum are mainly studied for alertness, appetite or weight, and the front panel reads "KETONE LIQUID DROPS".[2] The sales page says "No Stimulants", yet guarana and green tea are caffeine sources.[12] We walk through each claim against the evidence in does Cerebrozen work.
What ingredients are in Cerebrozen?
Cerebrozen's label lists chromium (0.7 mcg) and a 200 mg proprietary blend of 22 items, with no individual amounts.[2] Split evenly, that averages about 9 mg per item per serving. None of the 22 has a human trial for tinnitus or hearing loss, so every row below is graded Weak for hearing.
The blend, in label order: maca root, grape seed, guarana seed, African mango seed, eleuthero root, astragalus root, green tea leaf, gymnema leaf, coleus forskohlii root, capsicum fruit, grapefruit fruit, Panax ginseng, raspberry ketones, L-glutamine, L-tyrosine, L-arginine, beta-alanine, monoammonium glycyrrhizinate, GABA, L-ornithine, L-tryptophan and L-carnitine.[2]
| Ingredient | Dose disclosed? | What human research covers | Grade for hearing |
|---|---|---|---|
| Chromium picolinate | Yes, 0.7 mcg | Adult Adequate Intake is 25 to 35 mcg a day, so this is about 2 to 3% of it[16] | Weak (dose is trivial) |
| GABA | No | Stress and sleep, limited low-quality evidence[17] | Weak |
| Guarana seed | No | Small short-term alertness effects, mostly from caffeine[12] | Weak |
| African mango seed | No | Weight trials of poor methodological quality[19] | Weak |
| Raspberry ketones | No | No human trial of the ingredient alone; rodent data[18] | Weak |
| Gymnema leaf | No | Blood sugar in type 2 diabetes, small trials[20] | Weak |
| Coleus forskohlii | No | Body composition in 30 men at 500 mg a day of extract[21] | Weak |
| Licorice glycyrrhizin | No | Regular intake raises blood pressure and lowers potassium[14] | Avoid with high blood pressure |
| Grapefruit | No | Known for drug interactions[15] | Avoid with grapefruit-warning drugs |
| Other 13 blend items | No | No hearing or tinnitus trial found | Weak |
Missing from the label: vinpocetine, lion's mane, alpha GPC, ginkgo biloba, coenzyme Q-10 and magnesium citrate.[1][2] GABA is in the blend, and lemon extract appears only under other ingredients, alongside glycerin, water, stevia, xylitol, sodium benzoate, potassium sorbate, citric acid and natural flavors. Xylitol is toxic to dogs, so store the bottle out of a pet's reach.
Some copycat pages list the label ingredients and add a badge about FDA sign-off. Trust the label on the bottle you receive. Each item is broken down in our Cerebrozen ingredients guide.
Does Cerebrozen work for tinnitus?
There is no evidence that Cerebrozen works for tinnitus. No trial of the finished product exists, none of the 22 blend items has a human tinnitus or hearing trial, and the clinical guideline for tinnitus advises against dietary supplements for persistent, bothersome ringing.[9]
Here is the evidence, step by step:
- Finished product. We found no published trial of Cerebrozen. The vendor's "first week" claim is not backed by a study.[1]
- Ingredients on the label. None of the 22 blend items has a human tinnitus trial. Their research covers weight, alertness, blood sugar or exercise.[12][19][20]
- Doses. About 9 mg per item on average sits far below the doses used in those trials. Coleus extract was studied at 500 mg a day.[21]
- Advertised ingredients. Ginkgo is the best-studied of them for tinnitus. A 2022 Cochrane analysis found low to very low certainty evidence and "uncertainty about the benefits and harms" against placebo.[11] Ginkgo is not on the label anyway.
- Expert bodies. The NIH's NIDCD says supplements advertised for tinnitus have not been proven effective.[10] The AAO-HNS guideline recommends against ginkgo, melatonin, zinc and other dietary supplements for persistent tinnitus.[9]
Caffeine is often blamed by patients for making ringing louder, though the evidence on that is mixed.[12] The full breakdown is in our evidence check.
Cerebrozen side effects: who should ask a doctor first?
Cerebrozen's side-effect risk comes from a few label items whose amounts are hidden: caffeine from guarana and green tea, licorice glycyrrhizin, and grapefruit. Ask a doctor or pharmacist first if you take regular medicine, are pregnant or nursing, or have heart, kidney or blood pressure problems.[2]
- Caffeine sources: jitteriness, poor sleep and a faster heart rate. They add to coffee, tea and energy drinks, and the FDA counts 400 mg a day of caffeine as the level not generally linked to problems for most adults.[12][13]
- Licorice glycyrrhizin: raised blood pressure and low potassium with regular use; caution with diuretics, digoxin, steroids and blood pressure drugs.[14]
- Grapefruit: can raise blood levels of some statins, calcium channel blockers, anti-arrhythmics and immunosuppressants.[15]
- Gymnema and chromium: may add to the effect of insulin or diabetes drugs.[16][20]
- GABA and coleus: may lower blood pressure, adding to blood pressure medicines.[17][21]
See a doctor right away if:
- ringing starts suddenly with hearing loss in one ear;
- the sound pulses in time with your heartbeat;
- tinnitus comes with dizziness, vertigo or facial weakness;
- you get chest pain, a racing heartbeat or fainting after a dose.

What do Cerebrozen complaints and buyer reports show?
We found no public complaint record for Cerebrozen in the sources we could check on October 19, 2026, and one major source we could not check at all. The vendor says "we have not received a single complaint yet", which is a sales claim, not a record.[1]
| Source | Result |
|---|---|
| Better Business Bureau | No Cerebrozen profile found[22] |
| Trustpilot | NOT checked (page blocked, no archived copy) |
| FDA recalls (openFDA enforcement) | No matches[23] |
| FDA adverse event reports (CAERS) | No reports naming Cerebrozen[24] |
| FDA warning letters | NOT checked |
| FTC actions | NOT checked |
An empty database result is not proof of safety. What buyers report about refunds and shipping is tracked on our Cerebrozen complaints page.
How much does Cerebrozen cost?
Cerebrozen costs $147.95 for 2 bottles, $177 for 3 and $294 for 6 on the US ClickBank checkout, checked October 19, 2026.[6][7][8] There is no single-bottle option on that grid, and each order is a one-time charge with no subscription.

| Package | Per bottle | Checkout total | Shipping | Cost per day at 1 dropper |
|---|---|---|---|---|
| 2 bottles | $69 on the page | $147.95 | Page says free; total is higher | $2.47 |
| 3 bottles | $59 | $177 | Free in the US | $1.97 |
| 6 bottles | $49 | $294 | Free in the US | $1.63 |
At the label's upper direction of 2 droppers a day, a bottle lasts 15 days and the daily cost doubles. The 3 and 6 bottle orders add two e-books, "Hear Like A Pro" and "Powerful Ways To Sharpen Your Memory".[1] Coupon and sale claims are checked on our Cerebrozen price page.
What is the Cerebrozen refund policy?
Cerebrozen has a 60-day refund window counted from the date of purchase, not delivery, and you must get an approved return authorization (RMA) by emailing support first.[5] You pay return shipping, must send the bottles within 14 days of the RMA, and the address is Cerebrozen Returns 66-243, PO Box 90129, Lakeland, FL 33804.
The vendor's pages disagree. The guarantee box promises a "no-questions-asked" refund "even your empty bottles", but also says "(minus shipping and handling fees)".[1] The return-policy page allows partial refunds for items "not in its original condition" and lists "Some health and personal care items" as non-returnable.[5] ClickBank also accepts refund requests directly through its support site.[25]
Where can you buy Cerebrozen?
The only checkouts we confirmed for Cerebrozen are the ClickBank order pages linked from the vendor's site, checked October 19, 2026.[6] A second vendor page advertises "Try One Bottle For Just $179" through BuyGoods, which we did not confirm at checkout.[3]
Third-party listings on Amazon or Walmart are not linked by the vendor, so the 60-day guarantee and ClickBank refund route would not cover them. A listing elsewhere could also carry a different label. Our Cerebrozen on Amazon and Walmart page covers what to check before buying from a marketplace.
Is Cerebrozen legit?
Cerebrozen is a real product sold through a real payment processor, ClickBank, but the seller details are thin and the label contradicts the marketing.[1][2] The sales domain was registered on January 24, 2024 behind a privacy service, and the distributor address is a private mailbox in Miami.[4]
The vendor says the product is made in an "FDA registered facility" without naming it. FDA registration of a facility is not approval of the product. Support is listed as support@cerebrozen.com and +1-833-630-7222.[4] The seller and terms checks are laid out in is Cerebrozen legit.
Cerebrozen vs other approaches to tinnitus
The approaches with the best support for bothersome tinnitus are a hearing evaluation, hearing aids where there is hearing loss, sound therapy and cognitive behavioral therapy (CBT). Supplements such as Cerebrozen sit at the bottom of the list, because the guideline panel recommends against them.[9][10]
| Approach | Strength | Limitation |
|---|---|---|
| Hearing test and ear exam | Finds hearing loss or a cause that needs care[9] | Needs an appointment |
| Hearing aids | Help many people with hearing loss notice tinnitus less[10] | Cost; only fit if hearing loss is present |
| Sound therapy | Background sound can make ringing less noticeable[10] | Masks the sound while in use |
| CBT | Recommended by the AAO-HNS guideline for persistent tinnitus[9] | Several sessions; reduces distress, not the sound itself |
| Dietary supplements | Easy to buy | Guideline recommends against them; none proven[9][10] |
How do you take Cerebrozen?
The label says: "Shake well before each use. Take 1 or 2 droppers full daily. Place in mouth and swallow."[2] The sales page FAQ says something different: one full dropper a day, about 15 drops, under the tongue or mixed into water or juice.[1] When the two disagree, follow the label on your bottle and do not exceed it. Timing and missed-dose questions are covered in how to take Cerebrozen.
Cerebrozen: final take
Cerebrozen is a hard product to recommend for hearing. The bottle's own label lists an energy and weight-loss style blend with hidden doses, six of the eight advertised hearing ingredients are absent, and no ingredient on it has human evidence for tinnitus.[2]
It may suit a healthy adult who wants to try it anyway, takes no regular medicine, and is willing to use the 60-day refund window with an RMA and return postage. People on blood pressure, diabetes, heart or grapefruit-sensitive medicines, pregnant or nursing women, and anyone with new or one-sided ringing should skip it and book a hearing evaluation first. If you still want to buy, use the vendor's ClickBank checkout so the refund route applies.
Frequently asked questions
What is Cerebrozen used for?
The vendor sells Cerebrozen as a hearing support liquid and says it eases ear noise. Its own label, though, lists a 200 mg blend of energy and weight-loss style items, and no ingredient on that label has human evidence for tinnitus or hearing, checked October 19, 2026.
Is vinpocetine or ginkgo in Cerebrozen?
No. The sales page names vinpocetine, lion's mane, alpha GPC, ginkgo biloba, coenzyme Q-10 and magnesium citrate, but none of the six appears on the Supplement Facts label the vendor publishes. GABA is in the blend and lemon extract is a flavoring.
Does Cerebrozen contain caffeine?
The label lists guarana seed and green tea leaf extract, and both are caffeine sources. The amount is hidden inside the 200 mg proprietary blend, so you cannot count it against the 400 mg a day the FDA uses as a general limit for most adults.
What is the cheapest way to buy Cerebrozen?
The lowest total on the ClickBank checkout is $147.95 for 2 bottles, checked October 19, 2026. The lowest cost per bottle is the 6-bottle order at $294, or $49 each, which works out to about $1.63 a day at one dropper.
Is there a Cerebrozen discount or coupon code?
The price cut we confirmed is the per-bottle drop on bigger orders, checked October 19, 2026: $69 a bottle for 2 on the page, $59 for 3 and $49 for 6. Buy through the vendor checkout so the 60-day refund applies.
Can I buy Cerebrozen on Amazon?
The vendor does not link to Amazon or Walmart, and we confirmed checkouts only on ClickBank. A marketplace listing would sit outside the vendor's 60-day guarantee and the ClickBank refund route, and could carry a different label than the one the vendor publishes.
How many drops of Cerebrozen should I take?
The label says 1 or 2 droppers a day, placed in the mouth and swallowed. The sales page says one full dropper, about 15 drops, under the tongue or in water or juice. Follow the label on your bottle and do not go above it.
Can I take Cerebrozen with blood pressure medicine?
Ask your doctor first. The blend contains licorice glycyrrhizin, which can raise blood pressure, plus GABA and coleus forskohlii, which may lower it, and grapefruit, which affects some heart drugs. Doses are hidden, so the size of any effect is unknown.
How long does a bottle of Cerebrozen last?
The label lists 30 servings of 1 ml. At one dropper a day a bottle lasts 30 days. At the label's upper direction of two droppers a day it lasts 15 days, which doubles the cost per day.
Who sells Cerebrozen?
The main order page uses ClickBank, which shows on card statements as CLKBANK*CerebroZen. The distributor is listed as cerebrozen.com at a private mailbox in Miami, Florida, with support at support@cerebrozen.com and +1-833-630-7222.
