Sustamine absorbs from gut to blood better than glutamine alone

Blood levels of L-Glutamine—the most abundant amino acid in human muscles and blood—were higher in healthy human participants after they ingested Sustamine™, the only GRAS dipeptide as liquid-stable L-Glutamine, according to a recent clinical study.

L-Glutamine is one of 20 amino acids found naturally in the human body, and is mainly generated in muscle tissue from glutamate and ammonia. It is prevalently used in the intestines and immune cells. Various clinical studies have shown it also can aid in muscle recovery after strenuous activity.

The study measured the L-Glutamine blood levels of eight male participants after separately taking L-Glutamine and Sustamine (L-Alanyl-L-Glutamine). Tests showed the L-Glutamine level after Sustamine ingestion was 224% of that after L-Glutamine ingestion.
