Overview
Potassium metabisulfite is a compound long used in home winemaking and brewing circles, mainly to sanitize equipment and to help control unwanted bacteria and oxidation in a batch of wine, cider, or beer. This particular listing sells it as a 1 pound powder with no flavor or diet claims attached, which fits its role as a functional additive rather than a flavored consumer supplement.
It is worth being clear that while the listing carries the word potassium in its name, this is not the same category of product as a potassium gluconate or citrate supplement meant to be taken daily for nutrition. Shoppers should buy it for its intended winemaking or brewing use, and anyone unsure about food or beverage additive safety should look up dosing guidance specific to that hobby rather than general supplement guidance.
With a 4.7 star rating across 314 reviews and about 100 buyers reported purchasing in the past month, it appears to serve a smaller, more specialized audience of home winemaking and brewing hobbyists compared to the higher volume general potassium supplements in this list.

Who typically buys this product?
Based on its intended use, it is mainly bought by home winemakers, brewers, and picklers who need a sanitizing and preserving agent for their equipment or batches.
Should I take this as a nutritional supplement?
