Among people in the U.S., that number is 41.6 percent of adults — including 69.2 percent of Hispanics and 82.1 percent of African-Americans — data show. The trend is only increasing.
Vitamin D deficiency occurs as a result of insufficient sunlight exposure and dietary limitations. Some signs of mild insufficiency are generally subtle and non-specific – fatigue, back pain, muscle pain – so people don’t realize they may have a problem.
The vitamin actually functions as a hormone, and every single cell in the body has a receptor for it, which is why it affects many functions and processes that keep a person healthy and happy.
The new recommended daily amount, as per the National Institutes of Health (NIH), is 600 international units a day. Some people, depending on age, sex, or pre-existing medical conditions, may need more.
