Vitamin D Deficiency and Fragility Fractures: Why Experts Stress the Importance of Mega Dose Therapy, ETHealthworld
New Delhi: Vitamin D deficiency is emerging as one of the most overlooked contributors to poor bone health and fracture risk in India, according to experts who participated in a recent meeting organised by the Osteoporosis Society of India and attended by specialists in gynecology, cardiology, orthopedics, and endocrinology.
The experts highlighted that despite abundant sunlight, studies suggest that nearly 70–80 per cent of Indians may have inadequate Vitamin D levels, affecting people across all age groups—from children and working adults to postmenopausal women and the elderly.
They warned that low Vitamin D levels can silently weaken bones over time, increasing the risk of osteoporosis, muscle weakness, falls, and fragility fractures. In many cases, patients become aware of the deficiency only after sustaining fractures from minor falls or routine activities that healthy bones would normally withstand.
Vitamin D’s Critical Role in Bone Health
Experts emphasised that Vitamin D is essential for calcium absorption, making it a key factor in maintaining strong and healthy bones. Without sufficient Vitamin D, calcium absorption declines significantly, leaving bones weak, brittle, and more susceptible to fractures.
In addition to supporting bone mineralisation, adequate Vitamin D levels help maintain muscle strength and balance, reduce the risk of falls among older adults, and promote faster fracture healing and recovery. Prolonged deficiency can lead to osteopenia, osteoporosis, and an increased risk of fragility fractures.

Strong Link Between Deficiency and Fractures
According to experts, several Indian studies have demonstrated a strong association between Vitamin D deficiency and fragility fractures, particularly among elderly individuals, postmenopausal women, patients with osteoporosis, people with sedentary lifestyles, and those living with chronic conditions such as diabetes and kidney disease.
Low Vitamin D levels not only compromise bone strength but also reduce muscle function, increasing the likelihood of falls—a leading cause of hip and spine fractures in older adults. Experts noted that hip fractures in India often occur nearly a decade earlier than in Western countries, underscoring the need for early preventive measures.
Why Deficiency Persists Despite Ample Sunshine
Despite being a tropical country, India continues to report widespread Vitamin D deficiency due to a combination of lifestyle and environmental factors.
Urban lifestyles and indoor work environments limit sun exposure, while air pollution and sunscreen use further reduce the skin’s ability to synthesise Vitamin D. Sedentary habits, increased screen time, and inadequate outdoor activity also contribute to lower Vitamin D production.
Additionally, natural dietary sources of Vitamin D are limited, and many Indians do not consume sufficient fortified foods or supplements. Ageing, obesity, diabetes, liver disease, kidney disorders, and certain medications can further increase the risk of deficiency.
Mega-Dose Therapy for Severe Deficiency
For patients with severe Vitamin D deficiency, doctors may recommend high-dose or “mega-dose” Vitamin D therapy under medical supervision to rapidly restore depleted levels.
Experts said this approach can help correct severe deficiency, improve calcium absorption, reduce bone pain and muscle weakness, support osteoporosis treatment, lower future fracture risk, and aid recovery following fractures. However, they stressed that such therapy should only be undertaken under medical guidance.
Who Should Get Evaluated?
The experts recommended Vitamin D testing and bone health assessments for individuals at higher risk, including:
- Adults above 50 years of age
- Postmenopausal women
- Individuals with recurrent body aches or persistent fatigue
- Patients with osteoporosis or low bone density
- People with a history of fractures
- Individuals with chronic diseases affecting bone health
- Those with prolonged indoor lifestyles or limited sun exposure
- Call for Greater Awareness
The experts stressed that maintaining healthy Vitamin D levels should become an integral part of preventive healthcare. They recommended regular outdoor activity, adequate sunlight exposure, a calcium-rich diet, timely Vitamin D supplementation when indicated, routine bone health screening for high-risk groups, and medical consultation before taking high-dose supplements.
They concluded that Vitamin D deficiency often remains undetected until significant bone loss or fractures occur. With osteoporosis and fragility fractures on the rise in India, greater awareness, early screening, and timely treatment—including medically supervised high-dose therapy where appropriate—could play a vital role in protecting bone health, preventing fractures, and improving long-term quality of life.
