Methylcobalamin is an organic compound and an endogenous vitamin B12. It exists in the blood and spinal fluid and can cross the blood-brain barrier without undergoing biotransformation. It can be used to treat or prevent vitamin B12 deficiency and its complications. After taking, methylcobalamin can replace endogenous vitamin B12, increase vitamin B12 levels, and improve vitamin B12 deficiency. Vitamin B12 is necessary for hematopoiesis, neural metabolism, DNA and RNA production, carbohydrate, fat and protein metabolism, helps improve the function of iron in the metabolic cycle, and assists folic acid in choline synthesis.

Our packing method is 1KG/Aluminium bags, 25kg/drum
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
