Is CerebroZen worth it?
Worth a look (4.6/10). CerebroZen names a creator, Daniel Lopez, and lists eight named ingredients (GABA, vinpocetine, lion's mane, Alpha GPC, ginkgo biloba, CoQ10, lemon extract, and magnesium citrate) out of a claimed 'over 20,' none with a stated amount. That is more transparency than an unnamed proprietary blend with zero ingredients listed, but still not enough to know whether any ingredient reaches a dose used in research. The core promise, that these drops support hearing, leans heavily on ginkgo biloba, and the best available evidence, a 2013 Cochrane review of four trials, found no benefit for tinnitus as a primary complaint. At $49 to $69 a month, you are paying supplement prices for an unverifiable formula.
What we liked
- Names a real person (Daniel Lopez) as the creator, more identifiable than a purely anonymous formula
- 60-day refund, consistent between the sales page and the ClickBank order form
- Free US shipping on every bundle tested
- Liquid dropper format may suit people who dislike swallowing pills
What we didn't
- No amount disclosed for any of the 8 named ingredients
- Formula claims "over 20 ingredients" while naming only 8
- Best available evidence review found ginkgo biloba ineffective for tinnitus as a primary complaint
- "4.98/5" rating and "zero complaints" are self-hosted, unverifiable figures
- $49 to $69 per month for a formula you cannot check against research doses
What is CerebroZen?
CerebroZen is a liquid supplement sold in dropper bottles, marketed for hearing support with a secondary pitch around mental sharpness and energy. The instructions say to take one full dropper (about 15 drops) daily, either under the tongue or mixed into water or juice.
The sales page names Daniel Lopez as the creator and includes a personal message thanking customers, along with customer photos and star ratings. It lists eight named ingredients out of a claimed 'over 20 carefully-selected ingredients': GABA, vinpocetine, lion's mane powder, Alpha GPC, ginkgo biloba, coenzyme Q10, lemon extract, and magnesium citrate. No amount is given for any of them, and the other ingredients that make up the rest of the claimed 20-plus are never named.
It is sold through ClickBank, which appears on the bank statement as CLKBANK*CerebroZen and handles the order and refund process.
Format: Liquid drops, one dropper (about 15 drops) daily under the tongue or in a drink. Sold by: CerebroZen (sold through ClickBank).
What is on the CerebroZen label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
The page claims 'over 20 carefully-selected ingredients' but names only 8, and gives no amount for any of them. There is no supplement facts panel with doses that we could read from the page, so the total formula cannot be checked against any research dose.
Do the CerebroZen claims hold up?
"Our new and improved CEREBROZEN formula works to support your ears using only research-backed, all-natural ingredients combined in the precise ratios required to support healthy hearing"
No specific ratio or amount is disclosed anywhere on the page, so "precise ratios" cannot be verified. The one named ingredient most associated with hearing claims, ginkgo biloba, was found ineffective for tinnitus as a primary complaint in a 2013 Cochrane review of four trials.
"We have not received a single complaint yet" and a 4.98/5 rating from over 2,000 reviews
These figures are hosted and controlled entirely by the seller, with no independent, verifiable review platform linked from the page.
"Scientific References" section listing studies on tinnitus, hearing loss, and cochlear cells
The references describe general research on hearing and the brain, not trials of the CerebroZen formula itself. The page includes a disclaimer that the cited organizations do not endorse or sponsor the product.

Which red flags did we find?
- No amounts for any ingredientEight ingredients are named with generic one-line benefits, but not one has a stated milligram amount.
- "Over 20 ingredients" claim understated on the label descriptionThe page lists 8 named ingredients while claiming more than 20 are in the formula, without naming the rest.
- Key cited ingredient contradicted by the best available evidenceA 2013 Cochrane review of ginkgo biloba for tinnitus found no benefit when tinnitus was the primary complaint.
- Self-reported reviews and satisfaction figuresThe 4.98/5 rating and "zero complaints" claim are not linked to any independent, checkable review source.
- List price vs. discount framingEvery tier is shown with a large crossed-out "you save" figure ($220 to $780) against list prices that do not appear to be sold anywhere at those levels.
Who should buy CerebroZen, and who should skip it?
It may suit you if
- You want to try a liquid supplement format and are comfortable with a formula whose ingredient amounts are not disclosed, relying on the 60-day refund if it does not help.
- You already have hearing concerns evaluated by a doctor and are looking for a low-stakes addition to your routine, not a replacement for medical care.
Skip it if
- You have new, sudden, or worsening hearing loss or tinnitus. See an audiologist or doctor; supplements are not a substitute for a hearing evaluation.
- You want to know exactly how much of each ingredient you are taking. This label gives no amounts for any of its 8 named ingredients, let alone the rest of the claimed 20-plus.
- You are relying on ginkgo biloba specifically for tinnitus relief. The best current evidence review found no benefit for that use.

CerebroZen FAQ
Is CerebroZen legit or a scam?
It is a real liquid supplement sold through ClickBank with a working 60-day refund and a named creator, so it is not a scam that disappears with your money. The concern is transparency: no ingredient amount is disclosed, and the ginkgo biloba ingredient central to its hearing pitch was found ineffective for tinnitus in the best available evidence review.
How much does CerebroZen cost?
Pricing depends on the bundle: $69 a bottle in the 2-bottle package ($138 total), $59 a bottle in the 3-bottle package ($177 total), or $49 a bottle in the 6-bottle package ($294 total). All ship free in the US.
Does CerebroZen work for tinnitus?
We found no study of the CerebroZen formula itself. Its main hearing-related ingredient, ginkgo biloba, was found not to help tinnitus as a primary complaint in a 2013 Cochrane review of four clinical trials.
How do I get a CerebroZen refund?
Contact the seller's toll-free number or email within 60 days of purchase and return the bottles, even if empty. The refund excludes original shipping and handling fees.
What is in CerebroZen?
The page names 8 ingredients: GABA, vinpocetine, lion's mane powder, Alpha GPC, ginkgo biloba, coenzyme Q10, lemon extract, and magnesium citrate, out of a claimed 'over 20' total. No amount is given for any of them.
