ZenCortex Fact Check: Sales Page Claims Sorted by Evidence
A ZenCortex fact check sorts each claim into one of three bins: stated on the bottle, unproven, or not supported by any ZenCortex trial. The bottle claims only "Supports Healthy Hearing†". The seller's info page goes further, with memory, mental acuity and "No Stimulants". No study tested the product.

What does the ZenCortex fact check cover?
The ZenCortex fact check covers the claims in three places: the bottle, the seller's info page and the brand badges. Each gets one of three verdicts.
The FTC says health claims generally need competent and reliable scientific evidence, usually human clinical testing (FTC, Health Products Compliance Guidance). We use that yardstick.
Is "Supports Healthy Hearing" a proven ZenCortex claim?
No, "Supports Healthy Hearing†" is a label statement, not a proven result.
It does not say the drops improve, restore or repair hearing, and no study of ZenCortex backs even the mild version.
Supplements for ringing in the ears have not been proven to work (NIDCD, Tinnitus).
- Label front“SUPPORTS HEALTHY HEARING†”Structure/function wording with the FDA dagger. No trial of ZenCortex exists, and the NIDCD says vitamins, herbal extracts and supplements are often advertised for tinnitus but none has been proven effective. (FDA, Dietary Supplements) (NIDCD, Tinnitus)
- Label front“Hearing Support Formula”A name, not a measured property. The blend prints a 200 mg total and no single amount, so no line can be checked. (eCFR, 21 CFR 101.36 Supplement Facts)
- Info page“Improve Your Hearing Naturally”A claim to improve hearing. Health claims need competent and reliable scientific evidence, generally human trials of the same product at the same dose. (FTC, Health Products Compliance Guidance)
- Info page“Strengthens Memory, Sharpens Mental Acuity”Untreated hearing loss is linked with higher dementia risk, and hearing devices with slower decline. A link is not a treatment, and no memory trial of ZenCortex exists. (NIA, Hearing loss in older adults)
- Info page“No Stimulants”The blend lists guarana and green tea extract, which carry caffeine. (MSK, Guarana) (NCCIH, Green Tea)
- Info page“Over 20 Carefully-Selected Ingredients”Counting the label: chromium plus 22 blend lines. Only chromium has a printed amount. (eCFR, 21 CFR 101.36 Supplement Facts)
- Info page21 references and university logosThe page's own text says it is not affiliated with those organizations; some references are animal or cell studies, a book and general articles. (ZenCortex info page)
- Brand badge“Made in USA” and “GMP certified”The label prints a distributor in Aurora, Colorado and no factory, certifier or audit date. (NCCIH, Using Dietary Supplements Wisely)
- Bottle backThe FDA statement'Not intended to diagnose, treat, cure or prevent any disease.' That line is accurate, and it is the one to keep in mind. (FDA, Dietary Supplements)
Claims as printed on the label, the info page and the brand badges. Health claims need competent and reliable scientific evidence, generally human trials of the same product (FTC, Health Products Compliance Guidance).
Are the memory and "Sharpens Mental Acuity" claims supported?
No, the memory and mental-acuity lines on the info page are not supported by any ZenCortex trial. Neither appears on the bottle.
Research does link hearing loss with a higher dementia risk, and treating hearing loss with aids may slow decline (NIA, Hearing loss in older adults). That concerns hearing aids, not these drops.
| Claim | Verdict |
|---|---|
| Supports Healthy Hearing† | Label statement |
| Improve Your Hearing Naturally | Unsupported |
| Memory and mental acuity | Unsupported |
| No Stimulants | Contradicted |

See packsIs "No Stimulants" true for ZenCortex?
Not quite, because two blend lines carry caffeine. Guarana and green tea extract are both on the label.
The FDA cites 400 mg of caffeine a day as an amount most adults tolerate (FDA, How Much Caffeine Is Too Much?). The label prints no caffeine amount.
See hearing supplement ads and the benefits page.

FAQ01
ZenCortex questions people ask
Has any clinical trial tested ZenCortex?
No clinical trial of ZenCortex is published that we know of, and the bottle does not claim one. A trial would test this exact product on people and report numbers.
Does ZenCortex have any stimulants?
It has caffeine sources. Guarana and green tea extract are on the label, although the info page says "No Stimulants". No amount is printed.
Is "Strengthens Memory" a claim on the ZenCortex bottle?
No. The bottle claims only "Supports Healthy Hearing†" and "Hearing Support Formula". Memory wording appears on the seller's info page, where no study of the product supports it.
