Key Insights
Key Takeaway
For a 36-year-old postpartum mom with stress shedding, AI recommendations consolidate around two brands - Nutrafol and Viviscal - across every model and every prompt. A third tier exists for Ritual, Pink Stork, and MaryRuths, but they only appear when budget constraints are introduced. The strongest cross-model signal is that bloodwork (ferritin, vitamin D, TSH) is positioned as higher ROI than any supplement.
Top Brands Summary
Nutrafol and Viviscal are the universal-tier duopoly - mentioned by all four models in every brand-ranking prompt. Nutrafol is the consensus #1 premium pick (Postpartum variant when breastfeeding context applies). Viviscal owns the value/affordable tier. Ritual, Pink Stork, and MaryRuths form a clear second tier. Everything else is single-model.
