Additional Information

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 and 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 essential for calcium and phosphorus absorption and for building healthy teeth and bones. It also plays a critical role in development of the cardiovascular, immune, and nervous systems. The amount of vitamin D3 recommended for children and adolescents was recently doubled to 400 IU by the American Academy of Pediatrics.

Treehouse Chewable Vitamin D3 is an easy way to give your children an age-appropriate dose and support their development and long-term health. It comes in a delicious, naturally sweetened berry flavour that your kids will enjoy. Great for kids 3 years and older.

Research in brief

Vitamin D insufficiency has been linked to common chronic diseases in children. Children with 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). New research suggests that vitamin D plays a role in maintaining healthy immunity and preventing diseases such as diabetes and cancer (Wagner et al., 2008).

Not all forms of vitamin D have been shown to support human health. Only vitamin D3 (cholecalciferol) is the natural form produced in your skin on a sunny day (Heaney, 2008). The American Academy of Pediatrics recently increased their recommendation for vitamin D3 to a minimum daily intake of 400 IU for all children and adolescents (Wagner et al., 2008). This new dosage has been shown to be safe for children (Pappa et al., 2012).
