DL-Aspartic acid
Aspartate is a vitamin-like substance called an amino acid. As a dietary supplement, aspartate is combined with minerals and is available as copper aspartate, iron aspartate, magnesium aspartate, manganese aspartate, potassium aspartate, and zinc aspartate.
Aspartates are used to increase absorption of the minerals they are combined with and to enhance athletic performance. Some forms are used to reduce brain damage caused by cirrhosis of the liver (hepatic encephalopathy) when given intravenously by a healthcare professional.
