Aspartic acid or aspartate is one of the 20 most common natural amino acids. As its name indicates, it is acidic, with a carboxylic acid component to its side chain. It is non-essential in mammals, and appears to serve as a neurotransmitter. It is also used in the urea cycle.
Aspartic acid may provide resistance to fatigue and thus lead to possessing more endurance.
