What can low vitamin D levels in infants result in?

Low vitamin D levels in infants can lead to delayed physical development due to its critical role in bone health and overall growth. Vitamin D is essential for the absorption of calcium and phosphate in the body, which are vital minerals for developing strong bones and teeth. When infants do not receive adequate vitamin D, they are at risk of conditions such as rickets, which is characterized by weakened bones and can significantly hinder their physical growth and motor skills. Therefore, ensuring sufficient vitamin D levels is crucial for normal development in infants.
