PRODUCT DESCRIPTION

Sialic acid (SA), scientifically known as "N-acetylneuraminic acid", is a naturally occurring carbohydrate. It was originally isolated from submandibular gland mucin, hence the name. Sialic acid usually exists in the form of oligosaccharides, glycolipids or glycoproteins. In the human body, the brain has the highest sialic acid content. 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 food source of sialic acid is breast milk, and it is also found in milk, eggs and cheese.

PRODUCT APPLICATION

N-Acetylneuraminic Acid 98% (Sialic Acid)

N-Acetylneuraminic Acid is the main component found in the brain, and it has been shown to be a key material for memory and learning functions.

N-Acetylneuraminic Acid is one of the nutrients in breast milk and can promote the brain development of infants.

As one of the eight essential carbohydrate nutrients for the human body, N-Acetylneuraminic Acid is widely present in cell membranes and neurons. It can enhance the body's immunity.
