In certain BACKGROUND example embodiments, the Subject Suffers from one or more 0003. In recent years it has been shown that copper plays of tremor, bradykinesia, rigidity, and postural instability. In an important role in the health of the human brain. Improper certain example embodiments, the subject suffers from Par copper oxidation has been linked to several neurological kinson's disease. In one example embodiment, the compo disorders including Alzheimers, Parkinson's, Menkes and sition comprises asparagusic acid. In certain example Wilson's disease. (10, 11, 12). Copper has also been iden embodiments, the condensation product comprises aspara tified as a critical cofactor in enzymes that activates the gusic acid, or a derivative therefor, and an amino acid. Such brain's neurotransmitters in response to stimuli. A recent as arginine. In certain example embodiments, the conden study by researchers at the U.S. Department of Energy's sation product is asparaptine. Lawerence Berkeley National Laboratory has shown that 0007. These and other aspects, objects, features, and proper copper levels are also essential to the health of the advantages of the example embodiments will become appar brain at rest. (12). Traditionally, copper has been regarded as ent to those having ordinary skill in the art upon consider a static metabolic cofactor that must be buried in enzymes to ation of the following detailed description of illustrated protect against the generation of reactive oxygen species and example embodiments.
