It is a component of the xlavase auxiliary group in the body, often used for the prevention and treatment of angular cheilitis, cheilitis, glossitis, ocular conjun...

Calcium L-threonate, also known as calcium bi[(2R,3S)-2,3,4-trihydroxybutyrate], a degradation product of vitamin C, is a white particle or powder, odorless and tasteless, easily soluble in water and has strong thermal stability, naturally exists in plants and human metabolites. As a third-generation ...

It is a naturally occurring nucleoside derivative, serving as a critical intermediate in the synthesis of phosphatidylcholine (lecithin) and an essential precursor for cerebral phospholipid biosynthesis. It can penetrate the blood-brain barrier, promote cerebral metabolism, participate in the repair an...

A white or off-white crystalline powder; odorless, slightly salty taste, hygroscopic. It is a neuroprotective agent and a crucial precursor in the synthesis of phosphatidylcholine. It can cross the blood-brain barrier, promote the biosynthesis of phospholipids in brain cell membranes, and improve cereb...

This product is a lipid-soluble quinone compound present in human mitochondrial cells, serving as a critical hydrogen carrier in the cellular respiratory chain. It participates in ATP (adenosine triphosphate) biosynthesis by promoting oxidative phosphorylation and maintaining biomembrane structural int...

Cysteine, a white crystalline powder, is a non-essential amino acid required by the human system, one of the components of glutathione, can accelerate the aging of free radicals. It is mainly used in medicine, cosmetics, biochemical research, etc.

Ectoin, known as tetrahydromethylpyrimidine carboxylic acid, is a new type amino acid derivative.  A white powder, soluble in water, glycerol, propylene, glycol and ethanol.

Ergothioneine (ergothioneine, EGT), known as 2-thioimidazole amino acid, is a white crystal, easily soluble in water. It is a natural amino acid derived from plants and can accumulate in animals, acting as an antioxidant.

Glycerin, is a colorless, transparent, odorless, viscous liquid with sweet taste, hygroscopic and non-toxic. Widely used in FDA-approved wound and burn treatment. It is also used as a bacterial medium, as a sweetener in the food industry and as a humectant in pharmaceutical formulations.

A colorless or yellowish clear viscous liquid; Strong hygroscopicity. It serves as a biological precursor of choline, efficiently crossing the blood-brain barrier to directly supply the brain with choline and phosphatidylcholine required for acetylcholine synthesis, thereby elevating cerebral acetylcho...

Arginine, also known as 2-amino-5-guanidine valerate, is one of the 20 basic amino acids synthesized in the liver and a non-essential amino acid (but it doesn't mean it's needed). It is the same basic amino acid as histidine and lysine, and arginine is the most basic.

L-histidine is an organic compound of imidazole amino acids, colorless needle or flake crystals with sweet taste. It is an important component of amino acid infusion and compound amino acid preparations, used in the fields of nutritional fortification, gastric ulcer treatment and biochemical research.
