Calcium and vitamin D pills showed little fracture or fall benefit in trials covering about 153,000 adults

What the research found
Study (evidence review). A BMJ review released 20 May 2026, and recirculated in September coverage, found little to no clinically meaningful effect on any fracture from calcium alone (moderate certainty; 11 trials, 9,067 people), vitamin D alone (high certainty; 36 trials, 92,045), or both together (high certainty; 15 trials, 51,126). Hip fractures and falls looked similar on mostly moderate to high certainty evidence. The pattern held after checks for age, sex, prior fractures and falls, and usual dietary calcium. The authors say this does not support routine calcium or vitamin D pills to prevent fractures and falls in most older people, and it may not apply to specific bone disorders or to people already on osteoporosis drugs. Not a reason to stop a clinician-prescribed product. Educational notes, not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
