Total daily intake of elemental calcium should be 1200 mg and vitamin D supplementation should be 800-1000 IU daily for adults over age 50 at moderate risk of vitamin D deficiency.
Ensure you get 1200 mg of elemental calcium daily from food and supplements combined. If you are over 50, take 800-1000 IU of Vitamin D3 daily to support bone health and calcium absorption.
GoodSupportsMEDIUM confidence
The total daily intake of elemental calcium (through diet and supplements) for individuals over age 50 should be 1200 mg [grade B]. For adults over age 50 at moderate risk of vitamin D deficiency, supplementation with 800–1000 IU (20–25 µg) vitamin D3 daily is recommended.
Why this rating
Grade B for calcium, Grade C for Vitamin D; controversy exists regarding efficacy and high-dose risks.
