25-hydroxyvitamin D3(25-OH-D3),namely 25-hydroxycholecalciferol. an important nutrient for healthy bones, is the metabolic product of the liver hydroxylation of vitamin D3. It is the main active form of vitamin D in human and animal blood circulation, and is an indicator of the nutritional status of vitamin D3 in the body. Molecular Structure CAS-NO:63283-36-3 25-hydroxyvitamin D3 monohydrate Formula:C27H44O2.H2O Molecular Weight:418.7 Cyclopentane polyhydrophenanthrene structure 25-OH-7-DHC special light rearrangement equipment, open loop to get 25-OH-D3 1.25% of 25-OH-D3 was obtained by microencapsulation. Features 1,The biological potency is 3~5 times of vitamin D3 which can be transformed into the final active metabolite more effectively. 2,No liver conversion is required which shortens the metabolic process of vitamin D3 and make it absorbed more quickly. 3.Not impacted by intestinal malabsorption liver damage or liver dysfunction. 4. The absorption mode is different from that of fat-soluble vitamins (A,D3,E,K3) and does not depend on bile secretion and the formation of fat-absorbing micro-aggregates.
