Vitamins

• Vitamin D3 allows the reinforcement of the immune system and increases the capacity of fixing calcium to maintain a good bone density.
• Clear to almost clear, pale brown to brown viscous solution. Pratically insoluble in water, miscible with ether and with light petroleum.
• Cholecalciferol is inactive. It is converted to its active form by two hydroxylations: the first in the liver to form 25-hydroxycholecalciferol. The second hydroxylation occurs mainly in the kidney to convert 25-OH vitamin D 3 into 1,25-dihydroxycholecalciferol.
