Source of data for the chart March 2012

The lack of vitamin D is even worse than the chart shows because:

1. It does not show the vitamin D levels for those at high risk of vitamin D deficiency
   such as seniors, dark skinned, and obese
2. It does not show the decrease during the winter for countries which are far from the equator
   Note: The Middle East has the lowest vitamin D during the summer - when they totally avoid the hot sun
3. It does not show how many have less than 30 ng
   Which even US govt publication said was needed just a few months before
4. It does not show current vitamin D deficiency, which is getting about 2X worse every 10 years
