Everything DoseRank tracks on the feminine wash shelf — Biotin. The category itself is never ranked: 2 products get scored the moment you say what you want them to do.

Questions
Each product gets a composite score blending clinical strength, evidence, dose fit, trust and value — computed for the goal you picked, across this category's products. The #1 on the DoseRank tab has the highest composite; the other tabs re-rank the same products by Value, Trust, or Popularity. Placement is never paid.
Start with a goal, not a brand
Browsing feminine wash supplements without a goal makes no sense — different products do different jobs, and “best” flips depending on which job you're hiring for. These are the 5 health outcomes that matter for this category. Pick yours, and the full evidence-ranked shelf loads for that goal alone.

No goal, no ranking.
A “best feminine wash supplement” list without a goal would be marketing, not evidence. Pick what you want to improve and DoseRank scores all 2 products against that goal's trials.
