  • The active metabolite of vitamin D (calcitriol) is formed following two sequential hydroxylation reactions in vivo. (physiciannutrients.com)
  • Without enough vitamin D, one can't form enough of the hormone calcitriol (known as the "active vitamin D"). This in turn leads to insufficient calcium absorption from the diet. (solar-facts-and-advice.com)
  • Vitamin D is the building block of the hormone calcitriol which works synergistically with PTH. (solar-facts-and-advice.com)
  • Vitamin D is modified by the liver to become 25-hydroxyvitamin D (also known as 25(OH)D). 25(0H)D is then modified in the kidneys to become calcitriol. (solar-facts-and-advice.com)
  • How the body regulates the processes of conversion of vitamin D into calcitriol and the resulting net increase or decrease of bone calcium are not fully known. (solar-facts-and-advice.com)
  • Finally, XLH patients demonstrate a normal or low serum concentration of 1,25-dihydroxyvitamin D3, suggestive of inadequate formation of this vitamin D metabolite. (medscape.com)
