Bone health is of primal importance during childhood. Not only is this the period in one’s life where bones are actively growing and developing, but this is also the time when you are building up your bones to ensure good bone health in your senior years.

Adequate levels of vitamin D in the bloodstream are essential for the development of strong, healthy bones and teeth. In fact, a deficiency in vitamin D can result in a childhood disease called rickets, where bones become soft and deformed. It was infrequent to hear of this disease a few decades ago as most children were getting an abundance of vitamin D while playing outside in the sun. Depending on where you live, it can be very difficult for children to play outdoors consistently. As a result, many children are getting much less time in the sun and consequently, less vitamin D.  Some researchers express concern about a global re-emergence of rickets disease in children.1   Rickets cases are seen particularly in children who live in northern areas, who are dark-skinned, or who are breastfed without appropriate vitamin D supplementation.2,3  Supplementation with vitamin D is recommended for all breastfed infants, and often recommended beyond infancy to support bone and teeth development.1

Children fall. It is inevitable. Healthy bones in children are important for the wear and tear during these tumbles. Insufficient vitamin D levels are associated with higher bone fractures in children.4

Vitamin D is important during childhood to support healthy bone development, but it is also important for keeping bones strong some thirty, forty or fifty years later in life. Approximately 90% of bone growth takes place between the ages of 10 and 20 or 30 years.5,6 During this period, a person’s bones will reach its peak density. Denser bones are a definite benefit because we start losing some of it in our later years. For women, bone loss mostly occurs rapidly immediately after menopause and then the rate of bone loss slows down.7 If too much bone density is lost, this increases the risk of osteoporosis and of bone fractures. Osteoporosis has been referred to as “a pediatric disease with geriatric consequences” 5.

The American Academy of Pediatrics, Health Canada and the Canadian Pediatric Society recommend that all exclusively breastfed, healthy, term infants receive 400 IU vitamin D per day and those over 1 receive 600 IU.8,9,10 The Canadian Paediatric Society recommends an intake of 800 IU vitamin D per day for northern Native communities during the winter months.11
