The vitamin D requirement for teens, which also applies to adults up to age 70, is 600 international units (IUs) per day. Vitamin D is especially important for teens because it helps the body absorb calcium. Together with calcium, vitamin D is vital to building and maintaining strong bones.

There are three ways for teens (and everyone) to get vitamin D:
  • Through supplements
  • From foods such as fatty fish and eggs, and fortified products including some orange juice, milk and breakfast cereals
  • By going outside; the body makes vitamin D from sunlight that penetrates the deeper layers of the skin
Talk to your teen's doctor about the best ways for her to meet her vitamin D needs.
To meet minimum nutritional requirements, teens need to consume at least four glasses of fortified low or non-fat milk daily or its dietary equivalent. Other foods rich in vitamin D include: salmon, tuna, eggs and fortified cereals.

"A vitamin supplement containing 400 IU of vitamin D is another alternative," said pediatrician Sandy Saintonge, MD. "We should also consider a national fortification strategy, perhaps including routine supplementation and monitoring of serum levels, but more research is needed to determine optimal vitamin D levels."
