Canadian Review of 69 Trials Finds Calcium, Vitamin D Barely Cut Falls or Fractures
3 articles · Updated · The Globe and Mail · Jun 22
Summary
A BMJ review of 69 randomized trials covering 153,902 adults found calcium, vitamin D, or both offered little if any protection against falls, fractures, or hip fractures in most older adults.
Moderate- and high-quality evidence showed similar results across age groups, vitamin D status, calcium intake, and prior fracture or fall history, undermining routine supplement use for prevention.
A small fracture reduction appeared when calcium and vitamin D were combined, but researchers said it was not clinically meaningful and was driven largely by higher-risk groups such as long-term-care residents.
The authors said the findings mainly apply to generally healthy, community-dwelling older adults; supplements may still help treat deficiency, cover dietary gaps, or support osteoporosis care.
An accompanying editorial urged a shift toward measures with proven benefit—balance and resistance training, home safety steps, and personalized fall-prevention programs—as 20% to 30% of adults 65 and older fall each year.
If supplements fail to prevent falls, what proven strategies can actually protect older adults?
Why is decades-old advice on calcium and vitamin D supplements for seniors now being overturned?

Overview
A major Canadian review published in The BMJ in 2026 analyzed data from 69 randomized controlled trials with over 150,000 adults and found a significant shift in understanding bone health and fall prevention. The review showed that routine calcium and vitamin D supplementation provides little to no meaningful benefit for most community-dwelling older adults in preventing falls or fractures. The evidence is strong, especially for vitamin D and combined supplements, and moderate for calcium alone. Based on these findings, the review urges clinicians and guideline panels to re-evaluate current recommendations and focus on more effective strategies.
