Cheapest means the cheapest we track, not the cheapest that exists. A price per 15 mg is a statement about price, not a suggestion of how much to take. How these numbers are made: How we compare.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
