## Short answer

The cheapest alpha-ketoglutarate (akg) we track costs **$0.077 per serving**, against a median of $0.187 across the 6 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.
