There's new guidance this week from the Institute of Medicine on the use of a popular nutritional supplement: Vitamin D. Vitamin D has been flying off the shelves in the past several years thanks to doctors' warnings that we are all Vitamin D deficient. Well, now comes news that we are consuming too much Vitamin D in supplements.

If it all sounds confusing to you, join the crowd. I remember the medical research over the summer about how most of us are vitamin deficient, that the average person should have about 30 nanograms of Vitamin D for every milliliter of blood.

It included recommendations to spend at least five to 10 minutes in the sunshine without sunscreen three times a week. And yes I followed the researchers led in this column by urging you to take more of the sunshine supplement.

Now it seems IOM researchers have determined the Vitamin D craze has gone a bit too far. The IOM panel warned that high levels of vitamin D, which are customarily sold in some dietary supplements, may positively increase the risk of kidney and tissue damage. The panel stressed that taking pills regularly and acquiring extra calcium helps raise into development of kidney stones and heart diseases.

Since 1997, based on IOMs vitamin D recommendation, it advised people whose aged from 51 to 70 to acquire 400 IUs, while those over 70 needs to take 600 IUs per day. However, experts say that majority of Americans and Canadian people do achieve that intake levels and they do not have any feelings that there is a widespread problem of vitamin D insufficiency.

So don't take 5,000 units of Vitamin D a day. More is not better after all. 400 to 600 IUs a day will do it.

That's my recommendation.
