Function and application:

L-Cystine should not be confused with cysteine, from which it is derived. Cystine is an oxidized dimer form of the amino acid, cysteine, that is common in many foods such as eggs, meat, dairy products, and whole grains.

L-Cystine is believed to play a role in protein synthesis, supports the heart, cardiovascular health, and lungs. It may also aid memory, focus, and contribute to a calm sense of well-being. In addition, Cystine may help contribute to healthy hair.

  • Supports the heart
  • Benefits cardiovascular health
  • Promotes healthy lungs
  • Aids memory & cognition
  • Contributes to a calm sense of well-being
  • Works to promote healthy hair

 It is mainly used in biochemical research, medicine for various alopecia, food seasoning, etc

For biochemical research. The biological medium was prepared. It is used in biochemistry and nutrition research. It can promote the oxidation and reduction function of body cells, increase white blood cells and prevent the development of pathogenic bacteria.

It is mainly used for various alopecia. It is also used for diarrhea, typhoid, influenza and other acute infectious diseases, asthma, neuralgia, eczema and various poisoning diseases, and has the role of maintaining protein configuration. It is also used as food seasoning.

Biochemical reagent for the preparation of biological medium. It is also an important component of amino acid infusion and compound amino acid preparation.

It is beneficial to animal development, increase body weight, liver and kidney function, and improve fur quality,

It can be used as cosmetic additive to promote wound healing, prevent skin allergy and treat eczema.
