L-GLUTAMINE
Background and Date of approval L-GLUTAMINE
L-glutamine is an amino acid naturally found in the body, crucial for protein synthesis, immune support, and maintaining gut health. It gained FDA approval in 2017, specifically to help manage complications in patients with sickle cell disease. This approval followed clinical trials that demonstrated L-glutamine’s effectiveness in reducing the frequency of painful sickle cell crises. These trials highlighted its potential to reduce oxidative stress, thereby decreasing pain episodes and hospitalisation rates in sickle cell patients. Additionally, L-glutamine has been extensively researched for its benefits in supporting immune function and aiding muscle recovery.
