About Amino Acid Testing

METHODOLOGY

Our amino acid profile measures 26 amino acids from a dried blood spot (DBS) sample using liquid chromatography with tandem mass spectrometry (LC-MS/MS), the gold standard for precision amino acid assessment. This provides a comprehensive picture of your amino acid balance for assessing nutritional status, recovery potential, and overall health.
