THREONINE

INCI: Threonine

What is Threonine?

Threonine is a kind of amino acid. Amino acids are known as building blocks in protein synthesis. It was discovered in 1936 by William Cumming Rose. Threonine is not synthesized in the human body and thus must be obtained from the diet. It is obtained from food sources such as meat, fish, cheese, and lentils.

Use & Benefits:

  • Cosmetic Applications: Threonine is used in a variety of cosmetic products. It functions as an anti-static and skin and hair conditioning agent.
  • Protective Film Formation: When used, it forms a protective film on the surface of the skin and hair.
  • Hydration: It helps in preventing water loss and keeps skin and hair hydrated.
  • Conditioning Agent: It conditions skin and hair and keeps them healthy.
  • Muscle Control: Apart from its use in cosmetics, it is used in muscle control disorders.
  • Protein Component: Many proteins, including tooth enamel, collagen, and elastin, contain the amino acid threonine.
  • Nervous System Support: Threonine is an essential amino acid for the nervous system, as well as for porphyrin and fat metabolism, and for preventing fat storage in the liver.
  • Gastrointestinal Relief: Threonine has been used to treat gastrointestinal issues, including indigestion, as well as anxiety and mild depression.
  • Conversion to Glycine: Threonine is converted to the amino acid glycine in the body. Glycine works in the brain to reduce muscular contractions that are undesirable and continuous.
