Guidelines Call for Increase in Vitamin D
New guidelines for vitamin D call for increasing the recommended dietary allowance (RDA) of vitamin D to 600 international units (IU) for everyone aged 1-70, and raising it to 800 IU for adults older than 70 to optimize bone health.
The guidelines, released by the Institute of Medicine (IOM), also raised daily calcium RDAs. The new guidelines call for a recommended dietary allowance of 700 milligrams of calcium per day for children aged 1 through 3, 1,000 milligrams daily for almost all children aged 4 through 8, 1,300 milligrams of calcium per day for adolescents aged 9 through 18, and 1,000 milligrams for all adults aged 19 through 50 and men until age 71. Women starting at age 51 and men and women aged 71 and older need 1,200 milligrams of calcium per day. (more…)
