Millions take calcium and vitamin D for bone health. A major review finds little benefit
Source: ScienceDaily
What the research found
A sweeping review of more than 153,000 adults found that calcium and vitamin D supplements, alone or together, do little to prevent fractures or falls in most older people. Researchers say the findings challenge routine supplementation for prevention and point instead toward strategies such as balance and resistance exercise.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
