The short version
NeuroQuiet and ZenCortex are both published in the Hearing Health category. Their documented SiftScores are 72.5 and 62.8, a difference of 9.7 points. The verdict above lists the documented reasons: NeuroQuiet has a higher SiftScore (72.5 vs 62.8).; NeuroQuiet offers a longer refund window (90 vs 60 days)..
Price and refund terms
At the documented single-purchase price, NeuroQuiet is $79.00 and ZenCortex is $79.00. The two prices are identical in our captured data. Refund terms: NeuroQuiet 90-day refund window; ZenCortex 60-day refund window. A longer window reduces the risk of a failed experiment, but it does not make the formula better. The Value component of the score accounts for both the price relative to the category median and the refund window.
Formula and transparency
NeuroQuiet lists no complete ingredient list in our captured data. ZenCortex lists 8 named ingredients: Grape Seed, Green Tea, Gymnema Sylvestre, Capsicum Annuum, Panax Ginseng, Astragalus, Chromium Picolinate, Maca Root. The two formulas do not share any named ingredients in our data. Only ZenCortex lists Grape Seed, Green Tea, Gymnema Sylvestre, Capsicum Annuum, Panax Ginseng, Astragalus. One side publishes no ingredient list at all, so the formula comparison is limited to the documented side; the missing list is a transparency gap, not a neutral tie. NeuroQuiet has no documented red flags in our data. ZenCortex has 1 documented red flag: exaggerated-claims. Ingredient order and blend totals are not the same as per-serving doses; without a Supplement Facts panel, part of the formula remains unknown. A longer ingredient list is not automatically a better formula; disclosure, dose and evidence quality matter more than the count.
Who should consider NeuroQuiet
Consider NeuroQuiet if the documented profile fits you: the page positions it for Adults comparing a nutrient capsule for hearing and tinnitus support. It is a supplement product at $79.00 with 90-day refund window refund terms. This is a fit based on documented attributes, not a claim that it works for your health situation.
Who should consider ZenCortex
Consider ZenCortex if the documented profile fits you: the page positions it for Adults comparing liquid hearing-support supplements. It is a drops product at $79.00 with 60-day refund window refund terms. If both fit, the refund window and formula disclosure are the tie-breakers, not the marketing.
What would change this verdict
This verdict is not permanent. It would change if a product publishes per-ingredient doses, removes a documented red flag, changes its price or refund window, or adds a product-specific trial. Today, the documented refund gap is 30 days and the score gap is 9.7 points; either can change with the next data refresh. We capture data daily and recompute the score after each refresh; the comparison page follows the data. If you spot a value that no longer matches the official page, report it through the contact page and we will verify it against the source.
