Everything DoseRank tracks on the calcium citrate shelf — Calcium Citrate and Vitamin D3 (Cholecalciferol). The category itself is never ranked: 59 products get scored the moment you say what you want them to do.
How to read the scores

A saved, shareable breakdown: your matched products, dose math, interaction flags to discuss with a clinician, and a price-tracked stack you can revisit.
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 calcium citrate 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 34 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 calcium citrate supplement” list without a goal would be marketing, not evidence. Pick what you want to improve and DoseRank scores all 59 products against that goal's trials.
