The U.S. Preventive Services Task Force recommends against vitamin D supplementation to prevent falls in community-dwelling adults aged 65 and older, a position it first issued in 2018 and carried into its 2024 update. What it does recommend for adults at increased risk of falls is exercise.
About one in four adults aged 65 and over falls each year, and a first fall roughly doubles the odds of another. So when early research suggested something as simple and cheap as vitamin D might reduce falls, it got a lot of attention.
The evidence has since moved. If you have read older articles recommending vitamin D to prevent falls, the current US guidance disagrees with them.
Why did people think vitamin D prevented falls?
A small study from Wake Forest Baptist Medical Center followed 68 homebound older adults over five months. Half received monthly high-dose vitamin D; half received a placebo. Participants who reached sufficient blood vitamin D levels reported fewer falls. The researchers themselves were careful to say that a study of 68 people needed replication in a much larger group before anyone acted on it.
Does vitamin D prevent falls in older adults?
It was replicated, at scale, and it did not hold up. The U.S. Preventive Services Task Force recommends against vitamin D supplementation to prevent falls in community-dwelling adults aged 65 and older — a position it first issued in 2018 and carried into its 2024 update on falls prevention. Its 2024 draft recommendation on vitamin D and calcium likewise concluded, with moderate certainty, that supplementation has no net benefit for primary fracture prevention in community-dwelling adults over 60.
Some trials of very high intermittent doses found more falls, not fewer. “Natural” and “harmless” are not the same thing, and more of a vitamin is not reliably better.
What is recommended to prevent falls in older adults?
The same USPSTF review that rejected vitamin D did recommend exercise interventions for community-dwelling adults 65 and older at increased risk of falls, and suggested a selective, individualized approach to multifactorial interventions. In other words: the thing that works is movement, strength and balance work — not a supplement.
None of this means vitamin D is useless. It has established roles in bone and muscle function, and people with a diagnosed deficiency are treated for it. The point is narrower: taking it specifically to avoid falling is not supported.
What this means for day-to-day care. The highest-value things you can do about falls are physical and environmental, not pharmaceutical — clear walking routes, remove loose rugs and cords, light the path to the bathroom, keep frequently used items within reach, and make sure footwear actually fits. If the person you care for is on multiple medications, dizziness on standing is worth reporting to their clinician; it is a common and fixable fall risk.
Frequently asked questions
Should older adults take vitamin D to prevent falls?
No. The U.S. Preventive Services Task Force recommends against vitamin D supplementation to prevent falls in community-dwelling adults aged 65 and older. It first issued that position in 2018 and carried it into its 2024 update. Some trials of very high intermittent doses found more falls, not fewer.
What causes an elderly person to keep falling?
About one in four adults aged 65 and over falls each year, and a first fall roughly doubles the odds of another. Common risks at home are loose rugs and cords, a dark path to the bathroom, items kept out of reach and footwear that does not fit. Dizziness on standing in someone taking multiple medications is a common, fixable risk worth reporting to their clinician.
Does this mean vitamin D is useless for older adults?
No. Vitamin D has established roles in bone and muscle function, and people with a diagnosed deficiency are treated for it. The point is narrower: taking it specifically to avoid falling is not supported. Never start, stop or change a prescribed medication without talking to the prescribing clinician first.
