Breastmilk is the sole source of nutrition for some newborns and infants. A deficiency of Vitamin D can cause softening of bones in infants, known as Rickets. With Vitamin D supplement, the baby's bones grow strong, and it acts as an immunity booster.

Vitamin D lets the body absorb calcium and phosphorus in a better way. With enough Vitamin D and calcium in the infant's body, muscles and bones grow appropriately and remain healthy and strong for life.

Vitamin D also helps the body to fight against various infections. It reduces the chances of any chronic disease by maintaining the heart's health.


With age, the baby starts eating solid food and gets enough Vitamin D, but infants may lack it because breastmilk is insufficient in Vitamin D. This way, Vitamin D supplement is a great choice. However, overdosage can be harmful to the infant. According to the American Academy of Pediatrics, 400 IU of Vitamin D supplement is necessary for breastfeeding infants daily.

It's essential to consider that this supplement is unnecessary for formula fed babies. The reason is that mostly enough Vitamin D is present in formula milk. If you partially feed your baby with formula milk and breastfeed the rest of the time, the baby may lack Vitamin D.

However, we recommend consulting your baby's healthcare provider regarding your infant's usage and recommended dosage according to the baby's nutritional needs.

Feeding your baby with the recommended dosage of Vitamin D supplement is usually not harmful. Also, it's best to start the supplement after the healthcare provider's recommendation.
