GCal-Plus 100 Capsules

Cholecalciferol, also known as vitamin D3, has a primary mechanism of action centered on its role in maintaining calcium homeostasis and promoting bone health. When Cholecalciferol is ingested, it undergoes two hydroxylation reactions in the body. First, it is converted to 25-hydroxyvitamin D (calcidiol) in the liver, and then further hydroxylated in the kidneys to form its active form, 1,25-dihydroxyvitamin D (calcitriol). Calcitriol acts as a hormone, binding to vitamin D receptors (VDR) in various target tissues, including the intestines, kidneys, and bones. This binding activates specific genes that regulate calcium and phosphate metabolism. In the intestines, it enhances calcium and phosphate absorption, ensuring sufficient mineral levels in the blood for proper bone mineralization. Additionally, Cholecalciferol influences bone remodeling by promoting osteoclast and osteoblast activity, which are essential for maintaining bone strength and structure.
