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 hormone precursor with legitimate use cases in adults over 40 with documented low DHEA-S — the Baulieu 2000 DHEAge study showed bone density and skin improvements in older women at 50 mg/day. Portions Master is a mainstream mass-retail brand; dose per capsule (25 mg, 50 mg, or higher) is the key transparency question and determines appropriate use case. Safety concerns are real: DHEA has androgenic effects (acne, hair loss/growth), should not be used by anyone under 40 without a lab-confirmed deficiency, and can worsen hormone-sensitive conditions (PCOS, hormone-receptor-positive cancers). 'Hormonal Support' framing is vague. Would move to Verified 70+ with per-cap mg on primary label, explicit 'not for use under age 40 without DHEA-S testing' warning, and third-party purity assay.
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.
