## Short answer

The cheapest evening primrose oil we track costs **$0.053 per serving**, against a median of $0.181 across the 20 products we can price per dose. Cost per dose is the current retail price divided by servings, as of 2026-11-13; it is not the sticker price, and the cheapest bottle is rarely the best value.
