Vitamin D is best known for its role in the development and maintenance of healthy teeth, bones, and cartilage in children and adults. Vitamin D helps the body keep bones and teeth strong by increasing absorption of calcium and phosphorus from the small intestine.
There are two forms of Vitamin D: ergocalciferol, which is found in such foods as fortified milk, herring, mackerel, tuna, salmon, sardines, eggs, fortified cereals and baked goods; and cholecalciferol, which is manufactured when the body is exposed to sun.
Vitamin D2 in promoting intestinal brush border calcium absorption and renal tubular reabsorption of phosphorus, increasing the concentration of serum calcium, serum phosphorus, in collaboration with parathyroid hormone (PTH), calcitonin (CT), old bones to release calcium phosphate, normal maintenance and regulation of plasma calcium and phosphorus concentration. Vitamin D2 is promoting the formation of new bone calcium deposition in parts, the citrate salt deposition in bone, bone calcification and bone cell function and bone-like tissue to mature.
1.For the prevention and treatment of vitamin d deficiency. Such as vegans, parenteral nutrition patients, pancreatic dysfunction with malabsorption syndrome, liver and gallbladder diseases (liver damage, liver cirrhosis and obstructive jaundice), intestinal disease (fatty diarrhea, diarrhea in Crohn's, chronic), gastric resection.
