importance of vitamin D

[heblaj01]

Since we are entering the flu season I thought this article might interest those susceptible to seasonal infections.
While a definitive scientific proof of the probable effectiveness of vitamin D3 in fighting various infections is not provided the evidence based data & the epidemiology observations described in the article are quite convincing.

The high doses of vitamin D3 used in some studies are now considered as normal by some MD's (such as Dr Vieh in other publications) at least for otherwise healthy people.
There is however a risk in taking extremely high doses for extended periods of time related to initiation or agravation of osteoporosis.
Since absorption of vitamin D3 varies from person to person, monitoring blood levels is advisable when taking high doses.
By the way, I read somewhere that a relatively moderate exposure to sun can cause blood levels to rise to the equivalent of 20000 IU of ingested D3.
