Additional Information

Babies and children need vitamin D for normal growth and development, however, vitamin D deficiency in children is now widespread. Vitamin D3 is formed in the skin by sunlight, but the skin cannot make enough during northern winters and may be limited on summer days when children are covered up or use sunscreen. Doctors recommend giving supplemental vitamin D3 to children of all ages.

Only vitamin D3 (also called cholecalciferol) is the natural form made by the skin on a sunny day. Research shows that the “sunshine vitamin” is not only essential for healthy development of teeth and bones, but also for the cardiovascular, immune, and nervous systems. The amount of vitamin D3 recommended for infants and children by the American Academy of Pediatrics is 400 IU daily.

TreehouseTM Liquid Vitamin D3 is an important supplement for kids, from infants to 13-year-olds. It comes with a baby-safe, measured dropper for accurate dosing. Liquid vitamin D3 can be taken directly or mixed into food, for a convenient way to support your children’s development and long-term health.

Research in brief

Vitamin D insufficiency has been linked to common chronic diseases in children. Children who have low vitamin D status have a greater risk for allergies, and make 50% more trips to the emergency room for severe asthma attacks (Litonjua, 2012; Brehm et al., 2010). A wealth of new research suggests vitamin D plays a role in maintaining healthy immunity and preventing diseases such as diabetes and cancer (Wagner et al., 2008).

Breast-fed infants are up to 10 times more likely to be deficient in vitamin D than formula-fed babies. Pediatricians continue to recommend breastfeeding for all its benefits, along with giving the infant supplemental vitamin D3 beginning in the first few days of life. The American Academy of Pediatrics recently increased their recommendation for vitamin D3 to a minimum daily intake of 400 IU for all infants and children beginning soon after birth (Wagner et al., 2008).
