Everything DoseRank tracks on the superba krill oil shelf — Astaxanthin. The category itself is never ranked: 20 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

These are the 16 health outcomes that matter for this category. Pick yours, and the full evidence-ranked shelf loads for that goal alone.
