At the request of Health Canada, along with several US federal agencies, the Institute of Medicine (IOM) held eight committee meetings since March 2009 to assess current relevant data and determine if the current recommendations for vitamin D and calcium intake are sufficient or if they need to be changed.
The updated report “Dietary Reference Intakes for Calcium and Vitamin D” was released on November 30, 2010. The new report recommends vitamin D intakes of 600 IU for most people age 1–70 and intakes of 800 IU for adults over age 70.
Calcium intake recommendations have increased to 700 mg for children aged 1–3 years, and to 1000 mg for children aged 4–8. Recommendations for men aged 51-70 have decreased to 1000 mg.
Recommended calcium intakes remain the same for youth aged 9-18 (1300 mg), adults aged 19–50 (1000 mg) women over age 50 (1200 mg) and men over age 70 (1200 mg).
