L-threonine is an essential amino acid that plays a role in protein synthesis and is a precursor for several important biomolecules. There is some scientific evidence suggesting that L-threonine is important for the maintenance and function of mucus membranes, particularly within the gastrointestinal tract. It is a critical component in the synthesis of mucin glycoproteins, which are major constituents of mucus secreted by epithelial tissues. Animal studies, especially in pigs and poultry, have demonstrated that dietary L-threonine supplementation can improve gut health by supporting mucin production and integrity of the intestinal mucus barrier. This, in turn, can enhance nutrient absorption and protect the gut lining from pathogens and irritants. However, in humans, direct clinical evidence supporting the use of supplemental L-threonine specifically for strengthening or supporting mucus membranes is limited. Most of the available research is preclinical or conducted in livestock, with the aim of optimizing growth and gut health in these animals. While the biochemical role of threonine in mucin synthesis is established, robust human clinical trials are lacking. Therefore, although the use of L-threonine for mucus membrane support is scientifically plausible and moderately supported by animal research, its application as a supplement for this purpose in humans is not strongly validated by direct clinical evidence.
