Vitamin D2 (as ergocalciferol):
Your body is able to better absorb calcium and phosphorus with the assistance of vitamin D, also known as ergocalciferol-D2, cholecalciferol-D3, and alfacalcidol. Vitamin D is a fat-soluble vitamin. When it comes to developing and maintaining healthy bones, getting the proper quantity of vitamin D, calcium, and phosphorus in one's diet is essential. Vitamin D is an essential component in the treatment and prevention of bone problems (such as rickets, osteomalacia). The production of vitamin D in the body is triggered by the exposure of skin to sunshine. It may be difficult to obtain sufficient vitamin D from the sun if you have dark skin, use sunscreen, limit your time in the sun, use protective clothes, or are older. Vitamin D combined with calcium is a treatment and prevention method for bone loss (osteoporosis). Vitamin D is often used in combination with other drugs to treat some illnesses that cause low levels of calcium or phosphate in the body (such as hypoparathyroidism, pseudohypoparathyroidism, familial hypophosphatemia).Paul, Subhabrata, Shreya Chakraborty, Uttpal Anand, Swarnali Dey, Samapika Nandy, Mimosa Ghorai, Suchismita Chatterjee Saha et al.
