Chapter 6, Problem 5
The vitamins essential for normal adult bone maintenance and repair are:
(a) A and E
(b) C and D3
(c) B and E
(d) B complex and K
Verified step by step guidance1
Understand that vitamins essential for bone maintenance and repair primarily support collagen synthesis and calcium metabolism.
Recall that Vitamin C is crucial for collagen formation, which is a major component of bone matrix, aiding in bone repair.
Recognize that Vitamin D3 (cholecalciferol) helps regulate calcium and phosphate balance, which is vital for bone mineralization and maintenance.
Evaluate the options given and identify which pair includes both Vitamin C and Vitamin D3, as these are directly involved in bone health.
Conclude that the correct answer is the pair of vitamins that support both collagen synthesis and calcium metabolism, which are Vitamin C and D3.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Role of Vitamin D3 in Bone Health
Vitamin D3 is crucial for calcium absorption in the intestines, which is essential for maintaining proper bone density and strength. It helps regulate calcium and phosphate levels, promoting bone mineralization and repair.
Importance of Vitamin C in Bone Maintenance
Vitamin C is vital for collagen synthesis, a key protein in the bone matrix that provides structural support. Adequate vitamin C levels ensure proper bone repair and maintenance by supporting the formation of connective tissue.
Functions of Other Vitamins in Bone Health
While vitamins A, E, B complex, and K have various roles in the body, vitamins A and E are not primarily involved in bone maintenance, and B complex vitamins mainly support metabolism. Vitamin K, however, also contributes to bone health by aiding in calcium binding to the bone matrix.
