In Singapore, vitamin D for infant health is often highlighted due to its vital role in supporting bone development and overall growth. Since infants may have limited exposure to sunlight, which is the natural source of vitamin D, ensuring sufficient intake becomes important. Vitamin D helps the body absorb calcium and phosphorus, both essential for building strong bones and teeth. A lack of this nutrient in infants can increase the risk of rickets, a condition that causes bone weakness. Parents and caregivers are often advised to understand recommended levels of vitamin D for infant well-being during early development.
