Function
1. Promote intellectual development:
Swan's nest acid is an important component of brain gangliosides. It interacts with brain cell membranes and synapses to increase the reaction speed of brain nerve cell synapses, thereby promoting the development of memory and intelligence.
2. Improve immunity:
Swan's nest acid can improve human immunity, especially in the intestines, where it can fight against pathogenic bacteria, toxins and virus particles, preventing them from binding to intestinal mucosal cells, thereby enhancing the body's ability to resist pathogens.
3. Promote intestinal absorption:
Swan's nest acid can improve the intestinal absorption capacity of vitamins and minerals. According to the physical phenomenon of opposites attract, positively charged minerals and vitamins are easily combined with negatively charged swan's nest acid, thereby enhancing absorption.
4. Delay cell aging:
Swan's nest acid has a protective and stabilizing effect on cells, preventing the swan's nest acid on the cell surface from falling off, delaying cell aging, and having a longevity effect.
5. Beauty and skin care:
Swan's nest acid can effectively inhibit the activity of tyrosinase, reduce the production of melanin, and adjust the melanin metabolism balance of the skin, thereby achieving the effect of whitening the skin. In addition, bird's nest acid can increase the expression of elastin growth factor in the skin, promote the production of elastin, and gradually lighten skin wrinkles, making the skin elastic, firmer, and more youthful.
