Osteoporosis is not only related to calcium intake but also involves factors like vitamin D, exercise, and hormone levels. Calcium supplements provide only part of the calcium your body needs. If you lack vitamin D, calcium absorption will be affected. Additionally, lack of exercise, hormonal changes (such as menopause), and other factors can also lead to osteoporosis. Therefore, preventing osteoporosis requires a comprehensive approach, considering diet, exercise, and lifestyle habits.
