Top five reasons why doctors recommend vitamin D for infants and children

January 14, 2020

1. To supplement exclusively or partially breastfed infants Breastmilk 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, there is an increasing number of babies being breastfed and for a longer period of time. [1,2] Breastmilk is rich in nutrients. As more information has become available, studies now confirm that most mothers’ breastmilk does not contain enough vitamin D to meet their baby’s needs. [3,4,5] 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. Another option is to give a daily dose of vitamin D to their baby by following the recommendations of medical organizations.

2. To help prevent rickets Vitamin D has been proven to help prevent bone softening and malformations. Rickets is a disease found in children that are characterized by the softening and imperfect calcification of bones. This disease used to be more commonplace decades ago, and later almost disappeared for an extended period of time. However, in recent years, doctors have seen a spike in rickets cases in both cold and warm regions. [6]

3. 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 breastmilk. 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.

4. 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 bloodstream, so without vitamin D, ones’ calcium and phosphorus levels would drop. 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.

5. 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, as well as the more serious effects of too much sun exposure in children compared to adults, various medical organizations in the United States, Canada, and the United Kingdom recommend that infants under the age of six 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. [7,8,9,10, 11,12]
