## Calcium and Vitamin D Supplements Show Minimal Benefit for Bone Health, Major Study Finds
Calcium and vitamin D supplements offer minimal protection against bone fractures or falls in elderly individuals – prompting calls for authorities to reconsider guidance recommending these supplements to millions of citizens, according to groundbreaking research.
The significant analysis, released in the esteemed British Medical Journal, discovered no substantial clinical advantage from supplement use in lowering fracture or fall rates.
This finding contradicts established NHS recommendations advising elderly citizens to regularly consume vitamin D for skeletal wellness. Health authorities additionally suggest daily calcium supplementation for individuals with insufficient dietary calcium intake.
Annual expenditure by NHS England on vitamin D prescriptions exceeds £111million – a dramatic increase from merely £13million in 2001.
### The Scale of the Problem
Nearly one-third of individuals aged 65 and above experience at least one fall annually, with half of all women sustaining a bone fracture during their lifetime.
Specialists acknowledge that calcium and vitamin D, obtained through natural sources, play essential roles in maintaining skeletal integrity.
Dairy products including milk, cheese and yoghurt contain the highest calcium concentrations, alongside leafy greens such as kale and broccoli, plus oily fish varieties.
Vitamin D derives predominantly from direct sunlight exposure – with lesser quantities available through oily fish and egg yolks.
Nevertheless, specialists indicate longstanding doubts regarding the efficacy of vitamin D and calcium supplements – commonly consumed as daily tablets.
Vitamin D supplements and calcium may not help bone health, a major review has concluded
### What the Research Found
To evaluate the skeletal health benefits of these tablets, Canadian investigators from CIUSSS du Nord-de-l’Île-de-Montréal examined findings from 69 clinical trials encompassing over 153,900 adult participants.
They assessed the impact of calcium supplements, vitamin D, or combined supplementation, measured against placebo or no intervention.
The conclusion proved striking. Calcium supplementation demonstrated minimal to no impact on fracture risk.
Vitamin D alone performed equally poorly – with data from 36 trials involving more than 92,000 participants revealing no significant advantage. The combination of both supplements yielded no improvement.
Significantly, the supplements failed to provide protection even for individuals already diagnosed with osteoporosis – the skeletal fragility condition affecting approximately three million UK residents.
Principal investigator Olivier Massé, a clinical pharmacologist, stated: ‘Our review found little to no benefits from use of calcium, vitamin D, or combined supplementation on the prevention of fractures and falls.’
### Calls for Policy Changes
The research team now urges the NHS to comprehensively reevaluate recommendations for both supplements.
Specialists suggest that funds allocated to these pills would prove more effective when redirected toward exercise programs and lifestyle modifications, which demonstrate genuine impact.
‘Apart from exercise and drug treatments for osteoporosis, few interventions have been consistently shown to reduce the risk of fractures,’ the investigators cautioned.
Experts are now looking to the government to ditch its advice for all adults over the age of 65 to take the supplement to support bone health
‘Clinicians, guideline panels, and regulatory agencies should re-evaluate their general recommendations for calcium and vitamin D supplementation in light of current evidence.’
The research team additionally noted that calcium supplements cause adverse reactions in many elderly individuals, commonly producing bloating, constipation and abdominal discomfort, warranting use only when essential.
### Expert Concerns About Removing Guidance
However, certain specialists caution that eliminating supplement guidance could prove counterproductive.
Public health nutritionist Dr Emma Derbyshire, representing the Health and Food Supplements Information Service, contends that supplements remain vital for patients experiencing severe vitamin D and calcium deficiencies.
Approximately one in six adults and one-fifth of children reportedly suffer from severe vitamin D deficiency.
Research indicates calcium deficiency rates are alarmingly elevated among young women – with one-fifth of females aged 11 to 18 consuming below recommended quantities.
‘With vitamin D intakes from food well below recommended levels and a substantial proportion of young people already showing deficiency, alongside notable calcium intakes below safe thresholds, there is a clear and ongoing public health concern,’ states Dr Derbyshire.
‘These issues are also highly relevant in older adults, where inadequate intake can further accelerate age-related declines in bone health.
‘Those with dietary shortfalls such as vitamin D and Calcium, should carry on bridging gaps with supplementation.’
### A Balanced Approach Needed
Dr Richard Abel, a musculoskeletal specialist at Imperial College London, added: ‘The message is not “stop calcium and vitamin D”.
‘The message is that routine supplements should not be mistaken for proper fracture prevention. Osteoporosis is a serious, preventable and treatable disease.
‘The best way to help patients is to identify the people who are genuinely at high risk and those who may benefit from calcium and vitamin D because they are deficient or have low intake, and those who need proven osteoporosis medicines because their fracture risk is high.’
NHS England and the National Institute for Health and Care Excellence have been approached for comment.
