Threonine

Low levels of Threonine on an OMX test panel by Diagnostic Solutions Laboratory may indicate insufficient dietary protein intake, malabsorption, or increased protein catabolism. Threonine is an essential amino acid required for the synthesis of collagen, elastin, mucin, and immune proteins, making it vital for gut integrity, connective tissue repair, and immune function. Low threonine can also result from intestinal inflammation, impaired digestion, or imbalanced amino acid intake where other large neutral amino acids compete for absorption. Deficiency may contribute to poor gut barrier health, reduced muscle maintenance, and weakened immune resilience, especially during stress, illness, or restrictive diets.
