Price and refund terms
At the documented single-purchase price, NeuroPrime is $69.00 and Pineal Guardian is $69.00. The two prices are identical in our captured data. Refund terms: NeuroPrime 365-day refund window; Pineal Guardian 365-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.

Pineal Guardian lists 7 named ingredients: Yamabushitake (Lion’s Mane Mushroom), Spirulina, Pine Bark Extract, Chlorella, Elder Mahogany Neem, Ginkgo Biloba, Bacopa Monnieri. Shared ingredients: Spirulina, Chlorella, Bacopa Monnieri. Only NeuroPrime lists Tamarind, Lion's Mane Mushroom, Moringa, French Maritime Pine Bark Extract, Maidenhair Tree Extract (Ginkgo biloba), Neem. Only Pineal Guardian lists Yamabushitake (Lion’s Mane Mushroom), Pine Bark Extract, Elder Mahogany Neem, Ginkgo Biloba. NeuroPrime has 1 documented red flag: exaggerated-claims. Pineal Guardian 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 NeuroPrime
Consider NeuroPrime if the documented profile fits you: the page positions it for Adults comparing liquid memory-support supplements. It is a drops product at $69.00 with 365-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 Pineal Guardian
Consider Pineal Guardian if the documented profile fits you: the page positions it for Adults worried about memory and recall. It is a supplement product at $69.00 with 365-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 0 days and the score gap is 0.0 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.
What this comparison does not tell you

For this pair, the documented formula lists 9 named ingredients for NeuroPrime and 7 for Pineal Guardian. The documented price gap is $0.00. Doses are not published for every product in our data; when they are missing, we leave them unknown instead of guessing. Reviews are sourced customer statements, not clinical evidence. Use the individual product pages for the full safety and verification notes, and speak to a qualified professional about your own situation. Treat this comparison as a dated snapshot, not a guarantee or a medical recommendation.
