ZenCortex FAQ: Your Common Questions Answered

The front says "Supports Healthy Hearing†" and "Hearing Support Formula". The dagger leads to the FDA statement on the back: the claim has not been evaluated by FDA, and the product is not meant to diagnose, treat, cure or prevent any disease.

A bottle is 60 mL, or 2 fl oz, in amber glass with a black cap and dropper. One serving is 1 mL, one full dropper, so a bottle holds 60 servings. The drops are taken by mouth.

No. This website is run by a retailer, not the maker. The label prints a distributor in Aurora, Colorado, and names no factory, so we cannot say who manufactures the drops.

The label lists chromium at 0.7 mcg with 2% of the Daily Value, then one Proprietary Herbal Blend of 200 mg whose Daily Value is not established. The blend has 22 named lines and no single amount.

No. ZenCortex is a dietary supplement taken by mouth, not a liquid placed in the ear. Nothing on the label says to put it in the ear canal. Ear pain or drainage needs a clinician, not a supplement.

The other ingredients are deionized water, organic citrus extract, natural flavors, stevia (steviol glycosides) and xylitol. Xylitol can poison dogs (FDA, Xylitol Is Toxic to Dogs), so keep the bottle away from pets.

The label lists chromium (as chromium picolinate) plus 22 lines in one blend, so 23 named items. The seller's info page says "over 20 carefully-selected ingredients", a looser count of the same list.

Maca. A blend lists parts from most to least by weight (eCFR, 21 CFR 101.36 Supplement Facts), so maca can weigh up to 200 mg and nothing outweighs it. The last line, L-carnitine, can weigh at most 9.1 mg.

Probably some. Guarana and green tea extract, both in the blend, carry caffeine (FDA, How Much Caffeine Is Too Much?). The label gives no caffeine amount, so we cannot say how much. The info page's "No Stimulants" line needs that footnote.

Monoammonium glycyrrhizinate comes from licorice, and glycyrrhizin can cause serious effects such as irregular heartbeat in large amounts (NCCIH, Licorice Root). The amount is not printed. Heart, kidney or blood pressure conditions call for a doctor's advice first.

Yes. Chromium picolinate has its own line at 0.7 mcg, 2% of the Daily Value, outside the 200 mg blend. It is the only ingredient with a printed amount (NIH ODS, Chromium fact sheet).

Yes. Each ingredient has its own page with the label position, the studied dose and the evidence. For a few, such as gymnema and GABA, we could not find an authoritative page and say so.

The brand's badges say gluten free, dairy free and vegetarian. They are seller claims with no certifier. The label's ingredient list shows no gluten or dairy source, but ask the seller if you have an allergy.

Two bottles are $158, three are $207 and six are $294, which is $79, $69 and $49 a bottle on the seller's info page (ZenCortex info page). At two droppers a day that is about $2.63, $2.30 and $1.63 a day.

The seller's info page prints none, and we do not invent one. If you want a single bottle, ask the order desk whether it is sold and at what price.

On 3 and 6 bottle packs, yes, within the US, and each adds 2 free e-books. The 2-bottle pack adds shipping, but the amount is not printed, so confirm it at checkout.

The info page says orders ship within 24 working hours by FedEx or UPS, with 5 to 10 days domestic (ZenCortex info page). We cannot confirm real delivery times. Call the order desk with your order ID to track it.

None confirmed as of our check. Our order buttons go to the seller's checkout at zencortex24.com. Be careful with any other listing, because we cannot verify the seller or the lot.

The checkout is run by BuyGoods and shows the card logos it accepts. We do not see your payment details. Check the final total, including shipping on a 2-bottle pack, before you confirm.

No code is published on the official order page, and the brief describes no subscription. If a checkout offers a trial or auto-renewal, read the terms first (FTC, Pros and cons of free trials and auto-renewals).

Not yet. We publish a review only after matching it to a real order, and none has passed that check. The review slots on our reviews page stay empty, and the FTC bans fake reviews (FTC, Fake Reviews Rule announcement).

We cannot verify it. The seller's page shows a score and a review count, and we never reprint figures we cannot check. See our reviews page for how we handle them.

No trial of ZenCortex exists that we could find. Research on single ingredients is limited, and the NIDCD says no supplement has been proven effective for tinnitus (NIDCD, Tinnitus).

No study shows it. The info page says "Strengthens Memory", but the link in research is between untreated hearing loss and dementia risk, not drops and memory (NIA, Hearing loss in older adults). A hearing test is the useful step.

The seller's page does, with lines like "Improve Your Hearing Naturally". We do not repeat them as fact, and we write that the drops have not been shown to improve hearing. Be wary of any ad that promises a result or hides its source (FTC, Health Products Compliance Guidance).

Call the order desk at +1 (380) 868-3839 with your order ID. For pages on this site, write to [email protected], Monday to Friday, 9:00am to 5:00pm ET. That inbox cannot see orders.

Yes, we may earn a payment when you buy through our order links, and we say so on every page. We are a retailer of the product, not a neutral reviewer.
