Is ZenCortex Legit? A Checklist You Can Verify

You can verify the product type, serving size, ingredients and caution on the ZenCortex label, because they are printed on the bottle.

It is a 60 mL (2 fl oz) amber dropper bottle. A serving is 1 mL and a bottle holds 60. Chromium is 0.7 mcg, and one Proprietary Herbal Blend of 200 mg lists 22 lines. Under FDA rules the blend shows its total and lists lines from most to least by weight (eCFR, 21 CFR 101.36 Supplement Facts). That order is a real, checkable fact.

What the label does not do is print one amount per line. So the strongest claim you can check is that nothing is hidden by name, though amounts are hidden by design.

The bottle's claim, "Supports Healthy Hearing†", is modest and matches what the label can say. The info page goes further, and those lines do not match the evidence.

It says "Improve Your Hearing Naturally", "Strengthens Memory" and "No Stimulants". Guarana and green tea carry caffeine, so the last one is wrong in effect. The FTC expects health claims to rest on competent and reliable scientific evidence matched to the product (FTC, Health Products Compliance Guidance). We found no trial of ZenCortex.

1. 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)
2. 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)
3. 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)
4. 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)
5. Info page“No Stimulants”The blend lists guarana and green tea extract, which carry caffeine. (MSK, Guarana) (NCCIH, Green Tea)
6. 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)
7. 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)
8. 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)
9. 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).
