Many people believe that they are getting enough vitamin D from daily exposure to sunlight, but they may be mistaken. The National Institutes of Health states that there are many things that could prevent people from absorbing vitamin D through sun exposure, such as cloud cover and sunscreen use, which is why individuals should consume foods and supplements that contain the nutrient.
Recently, The Mail Tribune, an Oregon news source, published an article by one of its contributors who received some surprising news about her vitamin D levels. According to writer Sharon Johnson, she thought that she had been getting sufficient amounts of this nutrient from the sun and milk, but she was wrong.
"At my annual physical exam, I was found to have a significant vitamin D deficiency. I'd admittedly been poor about taking my drugstore vitamin D on a regular basis over the last year. I should have been more vigilant because I know vitamin D deficiency is a risk factor for bone problems, and I have a strong family history of osteoporosis," Johnson wrote for the Tribune.
Johnson said that after a she started getting between 600 and 800 international units of vitamin D a day, something changed in her for the better. She said she felt that she had more energy and was clearer headed than before.
Salmon, eggs, swordfish and milk are all good dietary sources of vitamin D.
