Overview

This is a 9.6 ounce bag of pure potassium bicarbonate powder, marketed for multiple uses including plant care, winemaking and baking cakes and cookies. It carries a 4.6-star rating across 295 reviews.

Unlike the capsule and drop supplements elsewhere in this batch, this is a plain powder positioned for household and hobby uses rather than as a daily dietary supplement. The title points to winemaking, baking and plant care as the intended applications, so buyers looking for a potassium supplement to take directly should look elsewhere.
