Vitamin D deficiency in children is a hidden health concern in the Philippines. Even in a tropical country with abundant sunlight, deficiency rates remain alarmingly high. Data shows that 77% of exclusively breastfed infants under 6 months in urban areas are vitamin D deficient, while among school-aged children (6–12 years old), about 1 in 10 are deficient and more than half are insufficient. These numbers highlight the urgent need for parents to understand the risks and solutions for vitamin D deficiency.
Why Vitamin D Matters for Children
Vitamin D — often called the “sunshine vitamin” — is essential for growing kids. It helps the body absorb calcium for strong bones and teeth, supports muscle function, boosts immunity, and ensures overall healthy development.
Without enough vitamin D, children face higher risks of weak bones, slower growth, or rickets — a condition that softens bones and causes deformities. This makes awareness of vitamin D deficiency crucial for parents.
Vitamin D Deficiency in the Philippines
-
Infants: A DOST-FNRI study found that 77% of exclusively breastfed infants under 6 months in Metro Manila were vitamin D deficient. Breastmilk is best for nutrition, but it contains very little vitamin D, which is why supplementation may be needed.
-
School-aged children (6–12 years old): The Expanded National Nutrition Survey (2018) revealed that 10.3% are vitamin D deficient, while 60% are insufficient.
-
Urban vs. rural: Kids in urban areas are more prone to vitamin D deficiency because of less outdoor play, pollution, and tall buildings blocking sunlight.
-
Dietary intake: Filipino children consume only 2 µg/day of vitamin D, far below the recommended 5 µg/day.
Symptoms of Vitamin D Deficiency in Kids
Vitamin D deficiency can be hard to spot at first. Watch out for these signs:
-
Fatigue or weakness
-
Leg pain or muscle aches
-
Irritability in toddlers
-
Delayed motor milestones in babies
-
Frequent colds or infections
-
Dental problems (weak enamel, delayed tooth eruption)
In severe cases, vitamin D deficiency can cause rickets, leading to bowed legs, knock-knees, or thickened joints.
Complications if Vitamin D Deficiency Is Untreated
If not addressed early, vitamin D deficiency may cause:
-
Rickets and bone deformities in infants and children
-
Growth delays and stunted height
-
Increased risk of fractures
-
Hypocalcemia (low calcium), which may trigger seizures
-
Weak immunity and frequent illnesses
Preventing Vitamin D Deficiency in Children
Parents can take these simple steps to prevent vitamin D deficiency:
-
Safe Sun Exposure
-
Vitamin D–Rich Foods
-
Add fatty fish (sardines, salmon, tuna), egg yolks, and fortified milk or cereals to your child’s meals.
-
Supplementation for Infants
-
Regular Pediatric Visits
Takeaway for Filipino Parents
Vitamin D deficiency is a common but preventable problem in the Philippines. From newborns who rely on breastmilk to school-aged kids spending more time indoors, the risk is real — even in a sunny country.
The good news? With safe sun exposure, a vitamin D–rich diet, and supplementation when recommended, parents can protect their children’s bones, growth, and immunity.
Bottom line: Don’t overlook vitamin D deficiency. A little sunshine and the right nutrition can make a big difference in your child’s health.
