Threonine is an important kind of anabolic that fortifies cereal, pastry, and dairy products. It rejuvenates human bodies and promotes the growth of infants. When applied in the pharmaceutical field, threonine can moisturize human skin due to the hydroxy group in its structure.
Combined with oligose, it protects human cell membranes and accelerates the synthesis of phosphatide and the oxidation of fatty acids. With a medicinal effect of preventing fatty liver, threonine preparation works as a component of compound amino acid injection. Meanwhile, threonine can be used for the production of monobactams, one of the highly effective and low-allergy antibiotics.
High-purity L-Threonine ensures predictable bioavailability and consistent dosing in feed formulations. Lower impurities reduce the risk of adverse reactions and improve product stability during storage.
Formulated to be highly bioavailable to poultry and swine, L-Threonine supports rapid absorption in the small intestine, leading to better growth performance and feed efficiency.
Critical for balancing limiting amino acids (with lysine, methionine). Correct ratios reduce nitrogen excretion and support lean tissue deposition.

Threonine is a major component of mucin and contributes directly to intestinal barrier function. Adequate supplementation enhances gut integrity and reduces pathogen translocation.
Involved in synthesizing immunoglobulins and acute-phase proteins, threonine supports immune response under stress or disease challenges.


Improves average daily gain (ADG) and feed conversion ratio (FCR) in pigs and broilers by optimizing amino acid balance.
Resistant to heat and shear, ensuring the delivered threonine remains active during common feed processes like pelleting and extrusion.
