N-Acetyl L-Tyrosine (NALT) is derived from L-tyrosine, one of the non-essential amino acids. It is sometimes regarded as a greater supplement than standard L-tyrosine because it can be more readily absorbed by the body and it also sticks in the body much longer than standard L-tyrosine which is often too easily excreted through the urinary tract. L-tyrosine is traditionally made use of in the process of protein synthesis. It is a nonessential amino acid which means that the body alone can manufacture large enough amounts of it that it need not be supplemented through dietary means. Tyrosine may also be used to form neurotransmitters that feed directly into the brain which scientists have determined may have an effect on cognitive abilities. Tyrosine is also a precursor that eventually becomes, through a process of synthesis, at least one of a few different hormones which is essential to bodily and mental development. Melanin, a chemical which determines the pigmentation of skin and the degree to which harmful sun†s rays can penetrate the skin, also needs tyrosine in order to be correctly manufactured. Tyrosine is more integral to the body than most would imagine, and when there is a deficiency of tyrosine in the body it shows through in many different and frightening ways, some of these including general weakness and fatigue, decreased protein levels, decrease in muscle mass, as well as possibly irreversible damage to the liver. NALT is a precursor to the very important neurotransmitters dopamine and norepinephrine. Tyrosine may also have an effect on the level of mental cognition that a person can reach, not to mention the fact that it can also reduce the level of physical fatigue resulting at the end of a long difficult exercise regimen. On top of that, tyrosine also protects healthy cells from free radicals by acting as an antioxidant.
