Doctors and other healthcare professionals recommend vitamin D for children, including infants. Here are the top five reasons for recommending vitamin D to this age group:

  1. To supplement exclusively or partially breastfed infants

Breast milk is the best nutrition that a mother can offer to her children. Due to a movement by healthcare organizations around the world to promote breastfeeding, more and more babies are being breastfed and for a longer period of time.2,3  Breast  milk is indeed rich in nutrients. As more information has become available, studies now confirm that most mothers’ breast milk typically does not contain enough vitamin D to meet their baby’s needs.4,5,6  It is possible to increase a mother’s vitamin D level to reach sufficient amounts for her baby, this requires a high level of vitamin D which should be discussed with a physician beforehand. The other option is to give a daily dose of vitamin D to baby by following the recommendations of medical organizations.

  1. To help prevent Rickets

Vitamin D has been proven to help prevent bone softening and malformations. Rickets is a disease that used to be more commonplace decades ago. It almost disappeared for an extended period of time. However, in recent years, doctors have seen a spike in Rickets cases in both cold and sunny climate areas.7

  1. To supplement the lack of vitamin D found naturally in foods

It is difficult to obtain vitamin D from foods. Certain foods are fortified with vitamin D, but it is difficult to eat enough of these foods in your own diet to pass enough vitamin D onto your baby through breast milk.  It is also likely your baby is not eating some of these foods yet, or she may just not be eating enough of these foods to obtain a sufficient amount of vitamin D.

  1. To help the development and maintenance of strong bones and teeth

Calcium and phosphorus are required to help develop and maintain strong bones and teeth. Vitamin D is the agent that allows calcium and phosphorus to enter the blood stream, so without vitamin D, ones’ calcium and phosphorus levels would below. Considering childhood is a stage of rapid bone growth and development, this is the time when you want to ensure an optimal level of vitamin D, calcium and phosphorus.

  1. To make up for the strict sun protection that is required for children, especially infants

Due to baby’s skin being more sensitive to the sun and due to the more serious effects of too much sun exposure on children compared to adults, various medical organizations in the United States8,9,10, Canada11,12 and the United Kingdom13 recommend that infants under the age of 6 months up to 1 year old should remain out of direct sunlight. Moreover, it is recommended that infants wear sunscreen at all times when they are outside.
