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 →
DHEA (dehydroepiandrosterone) is a real adrenal steroid precursor that declines by roughly 80% between age 20 and age 70 in humans and serves as a substrate for downstream sex hormone synthesis. Randomized trial evidence for DHEA supplementation is genuinely mixed: modest benefits in bone density in older women, potential adjunctive benefit in adrenal insufficiency, and marginal-to-null effects on mood, libido, and body composition in most general-population trials. The clinical dosing range is 25-50mg/day; 50mg is at the higher end. Safety notes: DHEA converts to both testosterone and estrogen downstream, which means users with hormone-sensitive conditions (prostate cancer, breast cancer, PCOS, endometriosis) should avoid it, and monitoring of estradiol/testosterone/PSA is prudent for long-term use. DHEA is banned in-competition by the WADA prohibited list. MRI Performance discloses the dose (50mg) directly in the product name, which is transparency in the right direction. The product loses ground because DHEA marketed for "healthy aging, hormone & adrenal support" for a general-consumer audience overstates the evidence base — most well-controlled trials in healthy middle-aged adults show minimal effect — and because the safety profile warrants clinician oversight that a retail product does not enforce.
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.

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.
