Vitamin D and Fractures in Older Adults: What the Evidence Says

Quick answer

Vitamin D is essential for bone health but is not on its own a fracture-prevention drug. In healthy older adults without deficiency, 2,000 IU daily did not reduce fractures in the large VITAL trial. Older people who are deficient, frail or living in care homes do benefit from vitamin D with calcium. What clearly cuts fractures in osteoporosis is osteoporosis medication plus fall prevention — and very large yearly doses may actually increase falls and fractures.

Most fractures I treat in older patients — femoral neck, proximal humerus, wrist and spine — happen after a minor fall on weak bone. Families often ask after surgery: “If he had taken vitamin D, would this have happened?” The honest answer needs nuance, which is what this article provides as part of our guide to osteoporosis.

Why are fractures so common in older adults?

Osteoporosis: bone loss with age and after menopause.
Falls: weaker muscles, poor balance and eyesight, sedating medicines, home hazards.
Vitamin D deficiency: less calcium absorption and weaker muscles.
Chronic illnesses and steroid use.

What do the studies show?

Study	Who was included	Result
Chapuy 1992 (France)	Older women in care homes, mostly deficient	Vitamin D3 800 IU + calcium 1.2 g daily reduced hip fractures
Cochrane review 2014	Postmenopausal women and older men	Vitamin D alone did not prevent fractures; with calcium it slightly reduced hip fractures
Sanders 2010	Women over 70	A yearly 500,000 IU dose increased falls and fractures
USPSTF 2018	Community-dwelling adults	Low-dose supplements not recommended for primary fracture prevention in healthy postmenopausal women
VITAL 2022	Healthy adults over 50 not selected for deficiency or osteoporosis	2,000 IU daily did not reduce fractures versus placebo

Table 1: Key studies on vitamin D and fractures.

The lesson: vitamin D helps people who are deficient, frail or in care homes — especially with calcium — but adds little for those with normal levels. So we test and treat according to the situation rather than give everyone large doses.

Does vitamin D reduce falls?

Older meta-analyses suggested daily doses of 700–1,000 IU might reduce falls, but larger recent trials did not confirm this in people with normal levels, while large intermittent doses were linked to more falls. We therefore prefer moderate daily doses and rely on exercise and home safety to prevent falls, as described in preventing falls and fractures in older adults.

Key numbers to know

In the VITAL trial of 25,871 people followed for 5.3 years, vitamin D alone did not reduce fractures in people without deficiency or osteoporosis (LeBoff et al., NEJM 2022).
In the FREEDOM trial, Prolia cut new vertebral fractures by 68% (2.3% vs 7.2%) and hip fractures by 40% (Cummings et al., NEJM 2009).
Calcium supplements lowered overall fracture risk by about 11% in randomised trials but did not reduce hip fractures (Bolland et al., BMJ 2015).

Treatment	When we use it	Notes
Calcium, vitamin D, exercise and fall prevention	Everyone with or at risk of osteoporosis	The foundation, but not enough alone in established osteoporosis
Bisphosphonate tablets	Osteoporosis without multiple fractures	Taken correctly on an empty stomach
Zoledronic acid (yearly infusion)	People preferring a yearly dose with good kidney function	Cut vertebral fractures by 70% in HORIZON
Prolia injection every 6 months	High fracture risk or moderate kidney disease	Must not be stopped abruptly without a follow-on drug
Bone-building drugs (teriparatide or romosozumab)	Severe osteoporosis and multiple fractures	Followed by a maintenance drug after the course
Fracture surgery (fixation or replacement)	When a hip or other fracture occurs	Together with starting osteoporosis treatment to prevent the next fracture

Table: treatment options for osteoporosis

At Prof. Dr. Ibrahim Shaarawi’s clinics in Nasr City, Mohandeseen and New Cairo (5th Settlement) we review your vitamin D, calcium and bone density results and examine the cause of pain or fracture before deciding on the right dose or osteoporosis treatment.

What actually prevents fractures in osteoporosis?

Osteoporosis medicines: in FREEDOM, 6-monthly denosumab (Prolia) cut new vertebral fractures by about 68% and hip fractures by about 40%; in HORIZON, yearly zoledronic acid cut vertebral fractures by about 70% and hip fractures by about 41%. See the 6-monthly osteoporosis injection (Prolia).

After the first fracture: make it the last

A fracture after a minor fall after age 50 is a warning sign that roughly doubles the risk of another fracture, especially in the first year. The American Society for Bone and Mineral Research urges that every fragility fracture triggers assessment and treatment. After treating the fracture I therefore arrange:

A bone density (DEXA) scan.
Vitamin D, calcium and kidney function tests.
Osteoporosis treatment after vitamin D is corrected.
Physiotherapy and a fall-prevention programme.

A practical vitamin D plan after 50

Situation	Vitamin D	What else
Healthy, no risk factors	Balanced diet and some sun; 600–800 IU daily if needed	Regular exercise
Deficient on testing	Treatment course then maintenance set by your doctor	Retest after 3 months
Frail older person or care-home resident	Usually 800 IU daily with adequate calcium	Fall-prevention programme
Established osteoporosis or fragility fracture	Correct deficiency before treatment, then maintenance	Osteoporosis drug + fall prevention

Frequently asked questions about vitamin D and fractures in older adults

Does vitamin D prevent fractures in older people?

It helps those who are deficient and care-home residents, especially with calcium. In people with normal levels, large trials such as VITAL found no fracture reduction from supplements alone.

What vitamin D dose is right for older adults?

The general recommendation is 800 IU daily after age 70; people who are deficient need a treatment dose set by their doctor. Very large yearly doses are not recommended.

Are vitamin D and calcium enough to treat osteoporosis?

No. They are an essential foundation, but established osteoporosis needs medication such as bisphosphonates, Prolia or zoledronic acid.

What should happen after a hip or wrist fracture in an older person?

After fracture treatment, a bone density scan, vitamin D testing, osteoporosis treatment and a fall-prevention programme, because the risk of another fracture rises sharply.

Are large yearly vitamin D injections useful for older people?

No; a large yearly dose was linked to more falls and fractures in a randomised trial. Moderate daily or weekly doses are preferred.
