What is L-Threonine?
L-Threonine is an essential amino acid that the human body cannot produce and must obtain from dietary sources or supplementation. It is a critical building block for proteins, and plays a key role in the synthesis of collagen, elastin, and muscle tissue. L-Threonine also supports immune system strength, gut lining health, and fat metabolism.

In clinical nutrition, L-Threonine is used in medical foods for patients with metabolic disorders or muscle wasting. In the animal feed industry, it’s widely added to swine and poultry diets to improve growth, feed efficiency, and immune resilience. Our L-Threonine is produced via non-GMO microbial fermentation, offering high purity, solubility, and bioavailability.
