Nutrition & Dieting - Vit D

Expert: Laurie Beebe, MS, RD, LD - 10/23/2009

Question
Based on recent research about the value of Vit D supplements, I have begun taking 1000IU of Vit D. I also get 800IU in my calcium pill and 500IU in my daily Centrum multivitamin. I also take 1000mg of fish oil daily. I am 58 year old male in good general health. What is your opinion about Vit D supplements and the general regimen I have described?

Answer
Dear Dave,

I'm not sure what the research tells you as far as amounts you should be taking per day. It sounds like you have no need for the vitamin D supplement in addition to the supplementation you are already receiving. The daily value for vitamin D is 400 IU. You are more than meeting that in your multivitamin, and then getting some more in your calcium pill. I couldn't say how much is in the fish oil you are taking, but you are also getting some in your diet, and likely receiving some of what you need in any daily sun exposure.

Since vitamin D is a fat soluble vitamin, excess amounts are stored in your body. The tolerable upper intake level is currently set at 2,000 IU, which you are exceeding (although later studies do suggest the upper limit could be set higher). Some effects of taking too much vitamin D include calcium deposits in soft tissues (which can damage organs) and kidney stones.

I suggest you see your physician to discuss what an optimal level is for you to be taking. Exceeding your needs of this vitamin could very well result in more harm than good.
