L-GLUTAMINE
Background and Date of Approval
L-glutamine is an amino acid naturally found in the body, essential for protein synthesis, immune function, and gut health maintenance. It received FDA approval in 2017 for managing complications in patients with sickle cell disease. This approval followed clinical trials that demonstrated L-glutamine's effectiveness in reducing the frequency of vaso-occlusive crises in sickle cell patients. The trials showed its capacity to reduce oxidative stress, thereby decreasing pain episodes and hospitalisation rates among affected patients. L-glutamine has also been extensively studied for its role in supporting immune function and facilitating muscle recovery.
