Solution(By Examveda Team)

The daily requirement of vitamin D for a healthy adult is 200 I.U.
The current recommendations suggest consuming 200 I.U. (10 - 20 mcg) of vitamin D per day. However, people who need more vitamin D can safely consume 1,000 - 4,000 I.U. (25 - 100 mcg) daily. Consuming more than this is not advised, as it is not linked to any extra health benefits.
Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults.
