[Rescored via evidence crawl] Previous score 75 → new 78. Evidence found: Ablon G, Kogan S. A Six-Month, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Safety and Efficacy of a Nutraceutical Supplement for Promoting Hair Growth in Women With Self-Perceived Thinning Hair. J Drugs Dermatol. 2019;18(1):55-59.. Rationale: Nutrafol Women's Vegan uses a plant-based reformulation (removing marine collagen, substituting with pea protein and other plant sources) while preserving core actives at studied doses (saw palmetto, ashwagandha Sensoril, curcumin, tocotrienols). The pivotal Ablon 2019 Women's RCT applies as bridging evidence for the reformulation, though direct vegan-formula RCT has not been published. Modest uplift to 78 acknowledges evidence transfer without full formula validation.
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.

NUTRAFOL WOMENS VEGAN 3 MONTH PACK is a product from NUTRAFOL @ NYALLERGY, categorized under Skin, hair & beauty supplements in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
75/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Evidence 78, Formulation 78, Manufacturing 72, Safety 72, Transparency 70, Sustainability 55. Scored as of 2026-08-24.
Nutrafol Women's Vegan — Nutrafol has published multiple company-sponsored but rigorous RCTs on their women's hair-growth formulation (Ablon 2018 in JCAD, Ablon 2019 double-blind RCT). Real hair-growth signal at 6 months in target populations. Vegan variant uses vegan-sourced actives without shark cartilage or fish collagen. Held below Elite by (1) trials are Nutrafol-funded rather than fully independent; (2) high price point ($209/3 months = ~$70/mo); (3) 3rd-party sustainability certifications thin. Would move to Elite 85+ with independently-replicated trial + sustainability certification.
Strongest: Evidence at 78/100 (quality of published RCT support for the active ingredients at the label dose) and Formulation at 78/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Transparency at 70/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 55/100 (sourcing practices, packaging, and corporate practice). 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.
Would move to Elite 85+ with independently-replicated trial + sustainability certification.
