Experts recommend that elders ingest at least 1000 to 1200 mg of calcium daily to prevent fractures, and many elders take calcium supplements to meet this recommendation. In this systematic review, investigators examined evidence from randomized, controlled trials and observational studies to determine the effects of dietary calcium and calcium supplements on fracture risk in older adults (age, >50).
Researchers analyzed 58 cohort studies of dietary calcium, milk, or dairy intake and fracture risk in >700,000 participants. Most of the studies (74%) reported no association between dietary calcium intake and risk for total fracture (14 of 22 studies), hip fracture (17 of 21 studies), vertebral fracture (7 of 8 studies), or forearm fracture (5 …
