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 →
Natrol DHEA 25mg is a defensible single-ingredient hormone product — DHEA supplementation has real evidence in adrenal-insufficient and older adults (Baulieu 2000, Villareal 2004 body-composition data), and 25mg is a reasonable maintenance dose. However this listing carries a 'BestBy10/26' quality flag indicating near-expiry inventory sold through a reseller ('Deal US'), which materially degrades label-potency confidence at time of consumption and pulls transparency and manufacturing scores down. DHEA is also a genuine hormone with androgenic/estrogenic conversion pathways requiring physician oversight — safety framing on a mass-market SKU is thin. Would score Verified 70+ as fresh Natrol-direct inventory with adequate warning language for hormone-sensitive users.
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.

Strongest: Evidence at 60/100 (quality of published RCT support for the active ingredients at the label dose) and Formulation at 60/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Sustainability at 45/100 (sourcing practices, packaging, and corporate practice) and Safety at 42/100 (adverse-event profile, interaction risk, and dose ceiling). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.

Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
