The short version
NeuroPrime and SynaBoost are both published in the Memory category. Their documented SiftScores are 67.8 and 61.8, a difference of 6.0 points. The verdict above lists the documented reasons: NeuroPrime has a higher SiftScore (67.8 vs 61.8).; NeuroPrime offers a longer refund window (365 vs 60 days)..
Price and refund terms
At the documented single-purchase price, NeuroPrime is $69.00 and SynaBoost is $69.00. The two prices are identical in our captured data. Refund terms: NeuroPrime 365-day refund window; SynaBoost 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
NeuroPrime lists 9 named ingredients: Tamarind, Lion's Mane Mushroom, Moringa, French Maritime Pine Bark Extract, Spirulina, Chlorella, Maidenhair Tree Extract (Ginkgo biloba), Bacopa Monnieri and 1 more. SynaBoost lists 3 named ingredients: Bacopa Monnieri, Huperzia Serrata, Rhodiola Rosea. Shared ingredients: Bacopa Monnieri. Only NeuroPrime lists Tamarind, Lion's Mane Mushroom, Moringa, French Maritime Pine Bark Extract, Spirulina, Chlorella. Only SynaBoost lists Huperzia Serrata, Rhodiola Rosea. NeuroPrime has 1 documented red flag: exaggerated-claims. SynaBoost 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 SynaBoost
Consider SynaBoost if the documented profile fits you: the page positions it for Adults comparing memory-support supplements. It is a capsules product at $69.00 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 305 days and the score gap is 6.0 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.
