    Product Description

    1-hydroxy Vitamin D3 is a synthetic prodrug which is converted by cytochrome P450 isoforms to the vitamin D receptor agonist 1,25-dihydroxy vitamin D3 in vivo.1,2 Such prodrugs are effective in suppressing the synthesis and secretion of parathyroid hormone in secondary hyperparathyroidism, an action which requires the vitamin D receptor.3,2,4 1-hydroxy Vitamin D3 supports bone growth both in postmenopausal women and in glucocorticoid-induced osteoporosis.5,6 It also provides renal and cardiovascular protection during chronic kidney disease.7,8
