Dietary supplements, including vitamins and minerals, play a role in maintaining bone health, but they should not replace a balanced diet. For osteoporosis prevention, calcium and vitamin D are particularly important. Calcium can be found in dairy products, leafy greens, and fortified foods, while vitamin D can be obtained from sun exposure and certain foods. Some people may need supplements if they cannot get enough from their diet, especially those with specific health conditions. Always consult a healthcare provider before starting any supplements.
