Health Watch - Supplements: Vitamin D

Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.


It’s not always easy to get all the nutrition we need from our diets. There are times when supplements may be necessary. This week on Health Watch, we’ll talk about supplements, when you need them and when they might be dangerous. Vitamin D has a host of benefits, but getting all you need from sunlight may require more sun exposure than you want.

Vitamin D may be able to help prevent a variety of diseases, including some forms of cancer, diabetes and multiple sclerosis. Sunlight is the best source of vitamin D, but that means being exposed to harmful rays. Dr. Jo Ann Carson, a nutrition expert at UT Southwestern Medical Center, says good food sources of vitamin D include fatty fish, fortified dairy products and egg yolks. If you take supplements, take no more than 1,000 IU a day and choose a supplement that includes the form D3, which results in the most active vitamin D in the body.
