Everything DoseRank tracks on the product collections shelf — Alpha-Lipoic Acid, Calcium Ascorbate, Grape Seed Extract and L-Methionine. The category itself is never ranked: 3.3k products get scored the moment you say what you want them to do.

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 product collections supplements without a goal makes no sense — alpha-lipoic acid, calcium ascorbate and grape seed extract do different jobs, and “best” flips depending on which job you're hiring for. These are the 45 health outcomes that matter for this category. Pick yours, and the full evidence-ranked shelf loads for that goal alone.
