Vitamin D Deficiency

The seriousness of Vitamin D deficiency has recently gained greater recognition.

Over 3000 articles have been published on Vitamin D were published in 2010 , making it the most prolific area in medicine that year.

Sunlight is integral to vitamin D production, yet sun exposure is associated with increased skin cancer rates.  We need to use sunblock, but it will lower our vitamin D level.

Lower rates of vitamin D have been associated with:

  • A doubling of the rate of heart attacks and strokes
  • Cancer (breast, ovary, lung, bowel, lymphoma, uterus)
  • Multiple Sclerosis
  • Alzheimers and Parkinsons Disease
  • Diabetes
  • Hypertension
  • Infections
  • Auto-immune disorders like rheumatoid arthritis
  • Osteoporosis
  • Depression
  • Pregnancy complications (pre-eclampsia , gestational diabetes, pre-term delivery)

Fortunately we can avoid the sun, yet maintain our vitamin D stores with safe and inexpensive supplementation.

In the mid 1990's, our clinic alerted our patients to the benefits of vitamin D3, importing D3 , at a time when only the inferior vitamin D2 was commercially available. Since the mid 2000's, Vitamin D3 is now readily available in Australia

  • A simple blood test demonstrates vitamin D level.
  • Current recommended blood levels are 75-250 nmol/L.
  • The lower levels have consistently been revised upwards.
  • Aim to have a blood level over 100, don't settle for a level of 50.
  • Vitamin D is fat soluble and it is rare for the levels to become toxic.
  • Following supplementation, stores balance at around three to four months. Retest after that time.

If you have children, remember to think of them.  Children's vitamin D dosage is more intricate and they are less comfortable with blood tests.

Most of us need an oral vitamin D supplement.
