Everything DoseRank tracks on the algae omega-3 shelf — Docosahexaenoic Acid (DHA). The category itself is never ranked: 31 products get scored the moment you say what you want them to do.
How to read the scores

Answer a few questions about your goals, habits, stack, and budget. Then, DoseRank will find the products that best match your needs based on your answers. It's free and only takes 60 seconds! No account is required.
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 algae omega-3 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 21 health outcomes that matter for this category. Pick yours, and the full evidence-ranked shelf loads for that goal alone.
