Final answer:
The main purpose of the cholecalciferol capsules is Vitamin D supplementation, aiding in healthy bone maintenance and various physiological functions like immune support.
Step-by-step explanation:
The blister strip mentioned contains cholecalciferol capsules, also known as Vitamin D3. The main function of this medication is Vitamin D supplementation. Vitamin D plays a crucial role in calcium and phosphorus absorption, necessary for maintaining healthy bones. Deficiency can lead to conditions like rickets in children and osteomalacia in adults. Cholecalciferol is synthesized in the skin upon exposure to UV radiation and further metabolized in the liver and kidneys to become the active form of Vitamin D that aids in multiple physiological functions including bone health, immune support, and regulation of calcium levels.
