Dr John Umhau, of the National Institutes of Health has teamed up with military specialists from the Uniformed Services University of Health to produce a landmark study on suicide among active duty military service members. If you remember, I introduced Dr Umhau to vitamin D back in 2005, when I asked him to be a co-author on my first influenza paper. At the time, John was interested mostly in fish oil.



Here is a link to the full text of the study along with links to other studies on depression, mental illness, suicide and low levels of vitamin D http://www.vitamindwiki.com/tiki-index.php?page_id=3608
Has everyone forgotten the 25 per cent increase in testosterone levels that resulted from
taking 3.1k ius of vitamin D after one year. This test was headed by Dr Stephen Pilz, at
the U of Graz, Austria. Testosterone is well known to generate good feelilngs about
oneself. Perhaps low levels of D could be causing low testosterone, and bring on
depression.
Without supplementation, I believe it is easy to understand why military personnel would be vitamin d deficient. They spend most of their time covered up head to toe.
In my opinion a 2 cents vitamin d soft-gel/day could prevent much suffering among our military personnel; and enormously reduce health costs among the general public. But who wants to reduce health costs???
@Jack…let’s also remember the tremendous stress our military personnel face…
Consider that Vitamin D absorption can be blocked by stress, and that constant stress will deplete the body’s Vitamin D supply….
