Bone Health Shocker: Supplements May Not Help Fractures

Recent extensive research challenges the widespread belief that calcium and vitamin D supplements effectively prevent bone fractures. A comprehensive meta-analysis published in BMJ, involving over 150,000 participants, found little to no significant benefit from these supplements, either individually or combined, for individuals not being treated for osteoporosis. This suggests that routine supplementation for fall and fracture prevention may need reevaluation. The study's findings are particularly relevant for adults without existing bone conditions, as the review primarily focused on participants not at high risk of fractures. Experts note that supplements can still be vital for individuals diagnosed with osteoporosis or osteomalacia. The research also highlighted that the trials typically followed participants for a median of two years, leaving long-term effects less understood. Experts stress that lifelong adequate intake of calcium and vitamin D through diet remains essential for bone health, and supplementation cannot reverse significant bone mass loss that has already occurred. Instead, consistent physical activity is identified as a primary strategy for reducing fall risk and strengthening bones. A 2019 Cochrane review indicated that general exercise reduced fall rates by 23% in older adults. Specific types of exercise, such as resistance and weight-bearing movements, help build muscle and bone density. Functional exercises and balance training, like tai chi, demonstrated the greatest direct impact on fall risk reduction. Weight-bearing aerobic activities also support bone density in the lower body. Additional measures for bone health include a balanced diet, limiting alcohol, avoiding smoking, and undergoing osteoporosis screening, especially for women aged 65 and older or those with specific risk factors. Any fall, even without injury, warrants discussion with a doctor to identify causes and prevent future incidents, potentially involving physical therapy or home safety modifications.
