Osteoporosis LTC Recommendations

2. Calcium & Vitamin D

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. If you have osteoporosis and/or are at risk for fracture, you should consume enough calcium and vitamin D through diet or supplements. Speak to your healthcare provider to learn more.

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


Healthy eating for healthy bones.
