NO: Vit. D is remarkably safe & sleepiness is not a known side effect. Side effects are very rare unless one takes toxic doses. I did find some reports of anxiety experienced by some after taking vit. D which is apparently a sign of magnesium deficiency remedied with magnesium. It's possible for someone to be allergic to fillers & binders in supplements so if it makes you sleepy try a different form.

Sure: There is a lot of good data coming out about the health benefits of vitamin d supplementation. As we spend less time out in the sun, especially in the winter months, our stores decrease. In addition, it is difficult to get a full days worth of vit. D in our diet. 1000-2000 iu daily should suffice.

I agree with Dr. Cheng. Studies indicate that vitamin D is a major deficiency in the USA public, because lack of sunshine on our skin, use of sunblockers etc. Some people require a much higher dose of Vitamin D.Best to have a blood test and take enough vitamin D-3 to stay in optimal range of 50-80.Children and adults all shoul get enough vitamin D-3 to stay healthy.
