I’d like to share with you something I recently learned that could be of great benefit to you or someone you know.  And no, I’m not selling anything. ;)

Vitamin D deficiency is a widespread problem among people of all ages.  Most of us don’t get much sun, and those of us who do usually block it out with SPF a gazillion sunblock, so we don’t have much Vitamin D.  Some online research I did today at many sites, including NIH, the Mayo Clinic, and WebMD indicated that vitamin D deficiency has been found to contribute to a long list of ailments including the following:

  • Heart Disease
  • High Blood Pressure
  • Cancer
  • Autoimmune Diseases, including Diabetes
  • Memory Loss, Alzheimer’s
  • Bone Pain
  • Osteoporosis
  • Chronic Fatigue
  • Depression
  • Weight Gain
  • Autism
  • Asthma

If you have any of these problems, and even if you don’t, I strongly recommend taking a blood test for vitamin D deficiency.  How great it would be to improve one’s health and quality of life simply by taking a vitamin!

Recent research indicates that current U.S. recommended daily allowances are too low.  Here is some information about recommended dosages and blood levels excerpted from http://www.webmd.com/osteoporosis/news/20080519/supplement-your-knowledge-of-vitamin-d:

The current recommended daily dose of vitamin D is 200 IU for people up to age 50, 400 IU for people aged 51 to 70, and 600 IU for people over age 70.

That’s not enough, Boston University vitamin D expert Michael Holick, MD, PhD, tells WebMD. Holick recommends a dose of 1,000 IU a day of vitamin D for both infants and adults — unless they’re getting plenty of safe sun exposure.

In 2008, the American Academy of Pediatrics recommended that breastfed infants receive 400 IU of vitamin D every day until they are weaned and drink at least 1 liter of vitamin D-fortified formula or whole milk each day. The AAP also recommends 400 IU/day of vitamin D for children and teens who drink less than a liter of vitamin D-fortified milk per day.

The Vitamin D Council recommends that healthy adults take 2,000 IU of vitamin D daily — more if they get little or no sun exposure.

A simple blood test — the 25(OH)D or calcidiol test — can tell your doctor whether your vitamin D level is low. The Vitamin D Council recommends that 25(OH)D levels be between 40 and 65 ng/mL. The U.S. National Institutes of health notes that 25(OH)D levels over 30 ng/mL are optimal, and that there is “insufficient data” to support recommendations for higher levels.

IANAD — I am not a doctor — so I am not qualified to confirm that this information is accurate. However, the potential benefit is so great that I wanted to bring this to your attention.  Qualified medical professionals, and others, feel free to comment on this article.
