Potassium Aspartate description

Potassium aspartate is a combination ingredient, in this case, the pairing of the mineral potassium and the salt form of the amino acid aspartic acid. It is found naturally in sugar cane and sugar beets but can also be lab synthesised. Aspartic acid is considered a non-essential amino acid, meaning it is produced by both plants and animals.Applied topically, potassium aspartate helps restore skin’s barrier and soothe the look of redness. It is also used in oral medications, where it is believed to function as a neurotransmitter.
