About this supplement
Potassium caseinate is a water-soluble protein derived from casein, the primary protein in milk, where casein is treated with potassium hydroxide to form the potassium salt. This form enhances solubility compared to acid casein, making it suitable for nutritional beverages, meal replacements, and protein-fortified foods. It provides a complete amino acid profile, including all essential amino acids, with high levels of glutamine and branched-chain amino acids. As a slow-digesting protein, it forms a gel or clot in the stomach, leading to sustained amino acid release over several hours. It is commonly used in medical nutrition, sports supplements, and food processing for its emulsifying, stabilizing, and water-binding properties.

Physical properties
Typically a white to cream-colored powder. Soluble in water, forming colloidal solutions. Insoluble in alcohol. Good emulsifying and water-binding capacity. Mild dairy odor.
How it’s made
Produced by treating acid-precipitated casein (from skim milk) with potassium hydroxide (KOH) to neutralize carboxylic acid groups, forming the potassium salt. The solution is then spray-dried to produce a fine powder.
