Function:L-Threonine is mainly used as a nutritional supplement. When heated with glucose, it will easily produce burnt aroma and chocolate aroma, which can increase aroma. It can also be used for biochemical research. Threonine is an important nutrient fortifier that can fortify cereals, cakes, and dairy products. Like tryptophan, it has the same effect of restoring fatigue and promoting growth and development.

Nutritional additives, also used to prepare amino acid infusion and comprehensive amino acid preparations.
For adjuvant treatment of peptic ulcer. It can also treat cardiovascular diseases such as anemia and angina pectoris, aortitis, and cardiac insufficiency.
