What is the primary benefit of Vitamin D?

Aids in digestion
Helps maintain heart action
Aids in bone and tooth formation
Regulates blood sugar levels

The correct answer is: Aids in bone and tooth formation

The primary benefit of Vitamin D is its crucial role in aiding bone and tooth formation. Vitamin D facilitates the body's absorption of calcium and phosphorus, which are essential minerals for building and maintaining strong bones and teeth. Adequate levels of Vitamin D help to prevent bone disorders such as rickets in children and osteoporosis in adults, highlighting its importance in skeletal health. While the other options touch on important health aspects, they do not reflect the primary function of Vitamin D. For instance, aiding in digestion, maintaining heart action, and regulating blood sugar levels are associated more closely with other nutrients and hormones. Thus, the emphasis on Vitamin D's contribution to bone and tooth health truly defines its primary benefit.
