Vitamin D: More Than Just the “Sunshine Vitamin”
Why Vitamin D Matters
Vitamin D is best known for its role in bone and muscle health—it helps the body
absorb calcium and maintain strong bones. But modern research shows its influence
extends much further: it plays a role in immune defense, mood regulation,
cardiovascular health, and even healthy aging.
Key Benefits of Vitamin D
- Bone & Muscle Strength: Deficiency increases the risk of osteoporosis, fractures, and muscle weakness.
- Immune Support: Adequate levels reduce the risk of respiratory infections and help regulate inflammation.
- Mood & Brain Health: Low vitamin D is associated with fatigue, low mood, and seasonal affective disorder.
- Metabolic Health: Deficiency has been linked to higher risk of type 2 diabetes and weight gain.
- Healthy Aging: Studies suggest vitamin D contributes to longevity by supporting multiple organ systems

Why Deficiency is Common in Bangkok
Even though Thailand has abundant sunlight, urban lifestyles limit exposure:
- Long office hours indoors
- Sunscreen use (essential for skin protection but blocks vitamin D production)
- Air pollution reducing UVB penetration
- Diets low in vitamin D–rich foods (fatty fish, fortified dairy) As a result, vitamin D deficiency is surprisingly common—even in sunny cities
Who Should Consider Testing and Supplementation
- People who spend most of the day indoors
- Those with fatigue, frequent illness, or low mood
- Older adults (skin makes less vitamin D with age)
- Patients with osteoporosis or metabolic conditions
- Individuals with darker skin, which naturally produces less vitamin D under sunlight
