Overview

Pure Encapsulations packages potassium in aspartate form, 90 capsules per bottle, formulated as a hypoallergenic supplement aimed at nerve, muscle, blood flow and cardiovascular support.

The aspartate form is often chosen for gentler absorption compared with some other potassium salts. This is a hypoallergenic formulation, meaning it is built to exclude common allergens and unnecessary binders, which fits a brand known for clean label capsules.
