How Does the Need for Vitamins and Minerals Change in Older Individuals

Recent research studies have reported that people 51 years of age and older can maintain adequate vitamin A status on intakes approximating the RDA level for this group. Contrarily, the requirement for vitamin D in this population is increased dramatically based on a reduced ability to make vitamin D in the skin as we get older. Furthermore, there may be reductions in the ability to properly metabolize vitamin D in the organs, especially in the liver and kidneys. In accordance the AI for vitamin D for people over 50 is double that of younger adults and the recommendation is tripled for those over the age of 70. In addition, some research suggests that these levels of intake for older populations might still under serve their needs.

Some researchers believe that the RDA and AIs for other vitamins such as vitamin B6 and B12 and riboflavin are also too low for older people. Increased vitamin E consumption may also be helpful in the prevention of heart disease. Furthermore, the reports of some scientific studies suggest that the 1200 milligrams recommendation for calcium may still be inadequate for people 51 years of age or older. For these and other reasons, a multivitamin and mineral supplement would benefit most adults over the age of 50.
