Sialic acid (SA), scientifically known as N-acetylneuraminic acid, is a naturally occurring carbohydrate. It was initially isolated from submandibular gland mucin, hence its name. Sialic acid typically exists in the form of oligosaccharides, glycolipids, or glycoproteins. The brain has the highest sialic acid content in the human body. The sialic acid content in the gray matter of the brain is 15 times that of internal organs such as the liver and lungs. The main dietary source of sialic acid is breast milk, and it is also found in cow's milk, eggs, and cheese.

1. Promotes Brain Development
Sialic acid is an important component of nerve cell membranes, especially during fetal and infant brain development, participating in synapse formation and nerve signal transmission. Studies have shown that breast milk has a high sialic acid content, which may have a positive effect on improving infant cognitive abilities.
2. Maintains Neuroplasticity
In adulthood, sialic acid helps maintain the stability of neuronal connections by regulating the structure of glycoproteins on the cell membrane surface, potentially delaying age-related cognitive decline.
3. Protecting the Intestinal Barrier
Sialic acid can bind to mucin in the intestinal mucus layer, enhancing its stability and reducing pathogen invasion of the intestinal mucosa, thereby maintaining the balance of the intestinal flora.
4. Antioxidant and Anti-aging Effects
Animal experiments show that sialic acid may delay the functional decline of tissues and organs by scavenging free radicals and reducing inflammatory responses, but its role in human anti-aging still requires further research.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
