It measures essential and nonessential amino acids, intermediate metabolites involved in protein metabolism, and dietary markers related to food peptides. It directly and indirectly highlights food deficiencies, gastrointestinal imbalances or defects in the detox process.

Urine amino acid analysis 

Amino acids are the building blocks of all structural proteins that are essential for the human body and require specific nutrients for their metabolism and utilization. Among the functions that amino acids perform are: energy generation, synthesis of neurotransmitters and hormones, tissue growth and repair, immune function, maintenance of lean mass and implication in inflammatory processes and formation of glutathione for detoxification from free radicals. In addition, diet, lifestyle, hormonal status, stress, exercise, intestinal health and particular clinical conditions can influence the use and urinary secretion of amino acids. 

Amino acid analysis measures essential and non-essential amino acids, intermediate metabolites involved in protein metabolism, and dietary markers related to food peptides.  Amino acid metabolism requires specific nutrients and their detection is able to directly and indirectly highlight situations of dietary deficiencies, gastrointestinal imbalances or defects in the detox process. 

The amino acid analysis is broken down as follows:

  • Essential amino acids that can only be introduced from food sources, essential for proper growth and energy formation
  • Non-essential amino acids that can be food-borne or synthesized by the body
  • Amino acids that are markers of vitamin B levels : B vitamins are involved in the metabolism of these amino acids, indirectly highlighting their deficiency
  • Amino acids directly or indirectly linked to neurotransmission
  • Urea Cycle Marker Amino Acids: By-Products Associated with Nitrogen Detoxification
  • Amino acid gastrointestinal markers deepen inflammatory situations, dysbiosis or intestinal pathologies

This test offers important clinical, metabolic, nutritional, and neurological data. Amino acid imbalances are often related to attention disorders, depression, chronic fatigue, and fibromyalgia. They could also highlight food deficiencies or excesses, liver pathologies or act as an in-depth study of the patient's gastrointestinal condition.  

For these reasons, the urinary amino acid test can be used to investigate some clinical scenarios:

  • Mood disorders and depression
  • Monitoring of slimming diets, states of malnutrition (especially in elderly patients and with low protein intake) or vegan/vegetarian diets
  • Poor digestion, malabsorption, and gastrointestinal problems
  • Chronic fatigue
  • Optimization of sports performance or in post-trauma healing paths (phases in which an increase in nutrients is required) or muscle fatigue
  • Kidney disease
  • Liver disease
  • Pre and Metabolic Syndrome (obesity, diabetes, insulin resistance)
  • Autism and Behavioral Disorders
  • Osteoporosis
