Vitamin D and disease

The RDA for vitamin D has been increased to 600 IU for anyone 1-70 years of age and 800 IU for those over 70.  Even these numbers are probably too low.  Vitamin D deficiency in the US tripled between 2007 and 2010.   Many studies are now showing that we are terribly lacking in vitamin D as a society and unfortunately it is associated with osteoporosis as well as a variety of other disorders including cardiovascular disease, dementia and Alzheimer disease. Sunlight is a good way to boost your levels as well as supplementation.  There are lab tests for vitamin D levels however it is a fat soluble, so too much can be an issue in and of itself.  Most people can tolerate up to 5000 IU without much of a problem but consult your doc if you think you may be deficient.
