<p>Vitamin D2 is a fat-soluble vitamin that is required for the absorption of calcium and phosphate. It can be obtained through dietary supplements or by exposure to sunlight. Vitamin D2 is a prohormone that needs to undergo two hydroxylation reactions in the liver and kidney before it becomes the active form, calcitriol. Vitamin D2 has been shown to have beneficial effects on bone mineralization and phosphatase activity, as well as an inhibitory effect on the production of parathyroid hormone. Hydroxyapatite, a component of bone tissue, has been shown to react with vitamin D2 in vitro, which may be due to its ability to act as an additive or stabilizer.END&gt;&gt;</p>
