Product Description
N-Acetylneuraminic acid (commonly abbreviated as NANA) is a naturally occurring sialic acid that plays a key role in many biological processes, particularly in cellular communication, immune regulation, and pathogen recognition. It is one of the most common forms of sialic acid found in nature and is widely distributed in various biological systems, including in glycoproteins, glycolipids, and glycosaminoglycans on cell surfaces.

Function
"Brain gold" for intellectual development: promotes fetal brain development and vision
Development of the omentum.
Anti-virus improves human immunity: Sialic acid will not be degraded by digestive enzymes in the digestive system, and can enter the intestines to prevent pathogenic microorganisms from adsorbing on intestinal cells, playing a role in resisting a variety of pathogenic bacteria.
Anti-Alzheimer's disease: sialic acid on the cell surface protects cells and macromolecules from enzyme and immune system attacks.
Anti-aging: maintaining cell stability, greatly reducing the rate of cell decline, extending the life of cells to achieve anti-aging effects.
Whitening and beautifying: the new darling of cosmetics, sialic acid has anti-tyrosinase activity. By inhibiting the synthesis and distribution of melanin, it can reduce the occurrence of spots and freckles, thereby achieving the effect of whitening and brightening skin color.
Application
Food: infant milk powder and complementary food supplements
Health products: immunity-boosting, anti-Alzheimer's products for middle-aged and elderly people; anti-aging, whitening health products for female users
