Ranked by real cost per dose (per gram for powders), not sticker price. We make no health claims — see each linked nutrient page for NIH-sourced facts, or read our methodology.
This page gathers the nutrients people commonly associate with gut health and ranks each one by cost per dose — the product’s current price divided by its servings per container, then normalized to one daily dose (or per gram for powders so a 20 g and a 25 g serving compare fairly). The table shows the single cheapest pick we currently track for each nutrient, sorted lowest cost first. Nothing here is paid placement, and a nutrient with no active deals simply drops off the list.
If you are assembling a stack for gut health, cost per dose is the figure that tells you what each option actually costs to take day after day — a smaller bottle with a lower sticker price can cost more per serving than a larger one. Use it to compare like-for-like and avoid overpaying; it is a price-comparison signal, not a measure of quality or suitability.
