# Best Astragalus by cost per dose

Source page: https://www.vitamindbc.com/best/astragalus · prices checked 2026-11-13 · 16 rankable products

## Short answer

The cheapest astragalus we track costs **$0.062 per serving**, against a median of $0.155 across the 16 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.
