Abstract:
Adequate calcium intake is one of the most important issues in the prevention and treatment of osteoporosis, which is considered a lifestyle-related disease. However, calcium is a nutrient that is rather difficult to take in appropriate amounts in traditional Japanese eating habits. Therefore, one of the effective means of preventing and treating osteoporosis is to supplement calcium intake, when an insufficient quantity is obtained in the three, daily meals. In addition to increasing the tolerable upper intake levels (UL) of calcium to 2,500 mg/day, and an instruction program for learning how to evaluate the nutritional state, and the right method of utilizing supplements is needed. Furthermore, learning how to balance other nutrients, such as mineral balance, should also be included.

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
