A New Solution for Seasonal Illness?

Vitamin D: the Ultimate Immune Modulator?

April 15, 2008

 

You have probably heard some of the press on Vitamin D since it has been all over the news as well as on Oprah. Having a chance at this conference to review the research again really impressed me that we are dramatically under-dosing. This inadequate intake is affecting our health on a variety of levels.

For years I have been aware of the Scandinavian studies showing a remission in fibromyalgia symptoms when supplemented with 5000 iu/day of vitamin D-3. This dose may sound high but recent information dictates that we will be putting the new daily recommended requirement closer to the 10,000 iu/day. For some individuals even higher dosing may be required for short periods of time.

There is sufficient data to indicate that much of our seasonal illness and infections result from immune suppression due to declining Vitamin D levels in the Fall and Winter months. This extends into other areas of immune function as well from breast and prostate cancer to cardiovascular and kidney function. Some researchers are even finding evidence that links Vitamin D deficiency to Autistic disorders.

Interestingly for those who think they get their D from the sun they need to know that only in latitudes below 34 degrees north (a line between Los Angeles and Columbia, South Carolina) is there sufficient exposure to allow for cutaneous production of vitamin D throughout the year. And when sun exposure is adequate they need to account for the time of day, cloud cover, smog, skin melanin content, and sunscreen which are all among the factors that affect UV radiation exposure and vitamin D synthesis.

I recommend everyone include 25-OH-Vitamin D on their blood panel the next time they do lab work. If you have any specific questions about your individual Vitamin D needs then give us a call and we will assist you in determining your levels.

Here are some interesting links on vitamin D:

http://www.vitamindcouncil.org
This is a private foundation that is dedicated to the dissemination of information on vitamin D. Interestingly their lead researcher is a local doctor from Atascadero.

http://ods.od.nih.gov/factsheets/vitamind.asp
This is the NIH (Government funded) site and their page on vitamin D.

http://www.orthomolecular.org

Here is a great site for nutrition in general.

Best of Health to You,
