Final answer:
Protein is the primary nutrition source that supports growth, maintenance, and repair of tissue, combined with vitamins and minerals such as vitamin K, calcium, and vitamin D that contribute to bone health.
Step-by-step explanation:
The nutrition source that supports growth, maintenance, and repair of tissue is protein. Proteins are essential nutrients that the body uses for building new cells, including the amino acids found in protein needed for healthy bone and muscle. Along with proteins, other critical nutrients such as vitamin K, calcium, vitamin D, magnesium, and omega-3 fatty acids contribute significantly towards bone health and tissue repair. For instance, vitamin K has a role in bone mineralization and works together with vitamin D, while calcium and vitamin D are crucial for bone growth and repair. Moreover, hormones like growth hormone and sex hormones are integral in the process of bone remodeling and repair.
