Application characteristics:
 
1. With silk from feed silkworm as raw materials, refined through biological process to get the mixed amino acid (silk essence), more than 85% of whose content are alanine, serine and glycin, is a functionally prominent nutrient with higher nutritional value.
 
2. Glycin and serine can not only be used as the essential materials of synthesizing protein in organism, but also be used as the predecessor of synthesizing the glutathione (GSH, SSG), which has certain preventive actions on heart disease and cancer. Meanwhile, the glycin also has the detoxication effects for some aromatics which can cause cancer. The rich alanine also helps promoting the metabolism of alcohol in human body and protecting liver. Moreover, tyrosine has obvious effect on preventing the old from Alzheimer disease.
 
3. Silk amino acid is very easy to permeate the derma layer of skin and get absorbed, nurturing skin as well. Due to its action in the enzyme metabolism, silk amino acid can keep and adjust moisture, prevent skin from ultraviolet radiation, restrain splash generation, facilitate anti-aging for skin.
