Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
Good Neighbor Pharmacy is AmerisourceBergen's private-label brand for independent pharmacies — essentially a store brand for the independent-pharmacy cooperative. 25mg DHEA at the studied dose range, but this is a generic-tier private label with no brand-specific formulation R&D and no publicly-posted per-lot testing. The listing text is generic ('essential precursor hormone,' 'supports vitality, energy, immune system, wellbeing') and does not surface any of the appropriate cautions for a hormone-active OTC. Same safety issues as previous DHEA products: hormone conversion, hormone-sensitive cancer risk, sports drug testing bans, drug interactions. Rejected on the same combined-dimension basis.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
FAQ data has not been generated for this product yet. See the site FAQ for general questions.
The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
