Pharmacology
Calcium citrate is a good source of calcium that is well absorbed on an empty stomach and does not cause constipation. Calcitriol is the active form of vitamin D3 that increases intestinal calcium and phosphate absorption and regulates bone mineralization. The biological effects of calcitriol are mediated by the vitamin D receptor, functioning as a ligand-activated transcription factor that modifies expression of target genes.
