L-Threonine Uses:

1. Mainly used as nutritional supplements. When heated with glucose, it will easily produce burnt aroma and chocolate aroma, which has the effect of enhancing aroma. It can also be used for biochemical research.

2. As a feed nutrition enhancer, threonine is an essential amino acid. Threonine is often added to the feed of juvenile piglets and poultry. It is the second restricted amino acid in pig feed and the third restricted amino acid in poultry feed. It is added to feeds based on grains such as wheat and barley.

3. Nutritional additives, also used to prepare amino acid infusion and comprehensive amino acid preparations.

4. For the adjuvant treatment of peptic ulcer. It can also treat cardiovascular diseases such as anemia and angina pectoris, aortitis, and cardiac insufficiency.
