Did you know?

Calcium and vitamin D are an important component to maintaining bone health. Many older adults do not get enough vitamin D from food or exposure to sunshine and some do not consume enough calcium through the food they eat. People who have osteoporosis and/ or who are at high risk for fracture, should consume enough calcium and vitamin D through diet or supplements.

How Much Calcium Do I Need?

  Age Daily Calcium Requirement (mg) (from diet and supplements)
19-50 1000
Pregnant/lactating women 18+ 1000



For all residents, we recommend dietary interventions to meet the recommended dietary allowance (RDA) for calcium.​​

  For all older adults in LTC   High Risk Low Risk
1200 mg daily through diet (3 servings of dairy or equivalent) 500 mg supplements daily recommended 500 mg supplements daily recommended*


Vitamin D

  High Risk Low Risk
800 – 2000 UNITS of Vitamin D3 800 – 2000 UNITS Vitamin D3*

*depending on resources and preferences


  • Calcium and Vitamin D are important components of a fracture prevention program
  • Calcium is best obtained through food (1200 mg daily)
  • If unable to consume calcium through diet, calcium supplements starting at 500 mg can be taken
  • Calcium supplements digest easily when taken with water, in the form of calcium citrate
  • Those with low blood levels of vitamin D, 2000 IU of vitamin D3 may be medically advised and managed
  • All residents need 800-2000 units of Vitamin D3 supplements daily – diet and sun exposure alone are not sufficient
