Vitamin D deficiency is becoming increasingly common, with modern lifestyle habits largely to blame. Despite being readily available through sunlight and certain foods like eggs, fish, and red meat, more individuals find themselves lacking this crucial nutrient. Dr. Karthiyayini Amar Mahadevan, an expert in developmental neurology, has voiced concerns over this silent health threat, which can detrimentally affect both mental and physical health.
Causes of Vitamin D Deficiency
- Limited exposure to sunlight due to indoor lifestyles.
- Excessive use of sunscreen blocking UV-B rays.
- Dietary habits that exclude fat, which is needed for Vitamin D absorption.
- Insufficient dietary intake from food sources.
The deficiency of this fat-soluble vitamin, necessary for bone growth and metabolism, can pass from mothers to children, impacting their development. A lack of Vitamin D absorption due to inadequate diet or insufficient sunlight can result in numerous health issues.
Health Impacts of Vitamin D Deficiency
Vitamin D deficiency can manifest in several ways, with symptoms ranging from muscle and bone pain to frequent illnesses and mood changes. Clarissa Lenherr, a London-based nutritionist, emphasizes that the deficiency can cause a range of symptoms:
- Increased susceptibility to colds and the flu.
- Muscle aches and bone pain due to poor calcium absorption.
- Low mood or increased risk of depression.
- Overall fatigue impacting energy levels.
These symptoms are particularly prevalent during the colder months when there is less sunshine, prompting health authorities like the NHS to recommend Vitamin D supplements from October to April.
The Role of Vitamin D in the Body
Vitamin D’s role extends beyond bone health; it is vital for regulating calcium and phosphate, maintaining healthy muscles, and supporting the immune system. Its deficiency has even been linked to long Covid, showcasing its importance in overall health and recovery from diseases.
Diagnosing and Treating Vitamin D Deficiency
Diagnosing a deficiency requires a simple blood test, which can be crucial in determining the correct supplementation needs. Lenherr advises against self-prescribing high doses due to potential toxicity and recommends professional guidance for appropriate dosage.
Strategies to Overcome Deficiency
Incorporating certain lifestyle strategies and diet tips can combat Vitamin D deficiency effectively:
- Regular sun exposure for about 10-15 minutes between 11 am and 3 pm.
- Gardening or outdoor activities to enhance sunlight absorption.
- Including Vitamin D rich foods in your diet like fortified milk and fatty fish.
- Performing Surya Namaskar for additional sun exposure.
For those at risk of deficiency, supplementation with the advised daily dose is important, especially during seasons with limited sunlight.
Expert Advice on Prevention
Dr. Mahadevan suggests that simply stepping outside or taking up hobbies like gardening can significantly boost Vitamin D levels. Moreover, including various dietary sources and understanding the balance between sun exposure and protecting the skin from harmful UV rays is critical.
Maintaining adequate amounts of Vitamin D as winter draws near is essential for maintaining the health of your bones, teeth, and muscles. A person’s general health and well-being are contingent upon their ability to recognise deficiencies and take appropriate action to address them.

Vitamin D deficiency is an increasing worry that cannot be disregarded, as the research reveals. Taking precautions against vitamin D insufficiency becomes essential for everyone, given its importance in maintaining immunity, bone health, and general well-being. Eating a well-balanced diet high in vitamin D-rich foods (e.g., eggs, fatty fish, and fortified meals) and getting enough sun exposure are good ways to keep levels at their best. For those at higher risk, or during the less sunny seasons, supplementation can serve as a beneficial adjunct under medical guidance to avert the potential health issues associated with deficiency.
