It might seem paradoxical: the UAE is one of the sunniest countries on Earth, yet Vitamin D deficiency is one of the most common nutritional problems I see in children at my Dubai clinic. Study after study in the region confirms it — a significant proportion of children in the UAE have insufficient or deficient Vitamin D levels, regardless of nationality, diet, or age.
Understanding why this happens — and what parents can do about it — is one of the most impactful things you can do for your child’s long-term health.
Why Is Vitamin D So Important for Children?
Vitamin D is essential for calcium absorption, which means it is directly responsible for building strong bones and teeth. But its role goes far beyond bone health. Vitamin D supports the immune system, influences mood regulation, aids muscle function, and plays a role in healthy brain development. In newborns and infants, adequate Vitamin D is critical for preventing rickets — a condition causing soft, weakened bones that can lead to skeletal deformities.
At my newborn and infant clinic in Dubai, Vitamin D supplementation is one of the first topics I discuss with new parents, because deficiency can begin from the very first weeks of life.
Why Are UAE Children So Deficient Despite All That Sunshine?
This is the question most parents ask — and it has a clear, evidence-based answer.
1. Avoiding the Sun (For Good Reasons)
The UAE’s summer temperatures regularly exceed 45°C. From May to September, most families keep children indoors during peak daylight hours. Even in cooler months, the brief time children spend outdoors — and the protective clothing, hats, and SPF sunscreen they wear — significantly limits the skin’s ability to synthesise Vitamin D.
2. Indoor School and Activity Schedules
Most children in Dubai spend the majority of their day indoors — at school, at home, or in air-conditioned malls. Physical education is often held in covered or indoor venues. The result is a generation of children with minimal direct sun exposure.
3. Darker Skin Tones
Melanin — the pigment that gives skin its colour — acts as a natural sunblock. Children with darker skin tones require significantly longer sun exposure to produce the same amount of Vitamin D as children with lighter skin. In the UAE’s diverse population, this is a major contributing factor to the high rates of deficiency across many nationalities.
4. Breastfeeding Without Supplementation
Breast milk is the ideal food for infants — but it contains very little Vitamin D. Exclusively breastfed babies who do not receive Vitamin D drops are at high risk of deficiency. This is a common and entirely preventable cause of rickets in the UAE. Infant health and wellness checks at my clinic always include guidance on this.
5. Dietary Gaps
Few foods naturally contain significant Vitamin D — mainly oily fish (salmon, mackerel, sardines), egg yolks, and fortified dairy products. Many children in the UAE consume diets low in these foods, relying instead on processed options that contain little to no Vitamin D.
Warning Signs of Vitamin D Deficiency in Children
Many cases of Vitamin D deficiency are silent — children show no obvious symptoms until levels are very low. However, parents should watch for:
- Frequent infections or a weakened immune system
- Unexplained bone pain or muscle weakness
- Delayed walking or motor development in infants
- Bowed legs or soft skull bones in babies (signs of rickets)
- Fatigue, irritability, or low mood
- Poor growth or failure to thrive
- Dental problems, including delayed tooth eruption
If your child shows any of these signs, a simple blood test can confirm Vitamin D levels. I recommend this test as part of routine pediatric health screening in Dubai — especially for children under five, exclusively breastfed infants, and children with limited outdoor time.
How to Prevent and Treat Vitamin D Deficiency in the UAE
Safe Sun Exposure
Encourage short periods of outdoor play in the early morning (before 10 am) or late afternoon (after 4 pm) when UV levels are lower, and heat is more manageable. Even 15–20 minutes of direct sunlight on arms and legs several times a week supports Vitamin D production.
Vitamin D Supplementation
The American Academy of Pediatrics recommends that all breastfed infants receive 400 IU of Vitamin D daily from the first days of life. For older children and adolescents, supplementation doses depend on current blood levels, age, and individual risk factors. Never self-prescribe high-dose supplements — excessive Vitamin D can be toxic. Always consult a consultant pediatrician for personalised guidance.
Dietary Sources
Incorporate Vitamin D-rich foods into your child’s diet: oily fish, eggs, fortified milk, and fortified cereals. While diet alone rarely corrects a deficiency, it helps maintain adequate levels alongside supplementation.
Regular Monitoring
Children at higher risk — infants, toddlers, children with chronic illness, or those with very limited sun exposure — should have their Vitamin D levels checked annually. At my clinic at Dubai Healthcare City, I include Vitamin D screening as part of comprehensive developmental and wellness check-ups.
When to Book an Appointment?
If you are unsure whether your child is getting enough Vitamin D — or if you have noticed any of the warning signs above — please do not wait. Vitamin D deficiency is straightforward to diagnose and very treatable when caught early. Untreated, it can affect your child’s bone development, immunity, and long-term health in ways that are much harder to reverse. Book Your Child’s Check-Up.
