Amino Acids (AA) are the basic structural units of protein found in every tissue of the body. They are involved in the creation of neurotransmitters, hormones, enzymes, antibodies, collagen, hemoglobin, immunoglobulins, receptors, muscles, and energy production.
Amino acid analysis identifies dietary protein adequacy and amino acid balance, gastrointestinal dysfunctions, forms of protein intolerance, vitamin and mineral deficiencies, renal and hepatic dysfunction, psychiatric abnormalities, susceptibility to inflammatory response, reduced detoxification capacity, and many other inherent and acquired disorders in its metabolism.
In published studies, fasting plasma is the preferred test on amino acid analysis as it was evidenced with the greatest number of validation. It detects the essential amino acids insufficiency and also shows high levels of reliability in indicating chronic stresses. Plasma drawn from blood at any given time will reflect AA leaving sites such as in skeletal muscle and flowing into sites of utilization in liver, brain and other tissues. Amino acids in urine is most sensitive in determining amino acid wasting and metabolism deviation associated with co-factor insufficiencies. Urine levels of amino acids decrease first and tend to give an earlier indication of inadequacy than do plasma levels.
