Q: I've been hearing a lot about vitamin D deficiencies lately. How would I know if I have a deficiency, and what can I do about it?
A: Vitamin D is essential for strong bones because it helps the body absorb calcium. Known as the "sunshine vitamin," it is produced by the body in response to sunlight. About 15 minutes of sunlight each day can supply all the vitamin D you need. If you get little or no sunlight or eat a vegetarian diet, you may be at risk for vitamin D deficiency. There are usually no symptoms with a deficiency, but research is revealing the importance of vitamin D in protecting against a host of health problems. Your doctor can check your vitamin D level through a simple blood test and may recommend supplements for any deficiency.
