This little article is hidden back in the main stream media.
It shows 2 important things. Beside not knowing the whole story, like how long these people were on this dosage of Vitamin D. This points to the fact that taking high doses of Vitamin D3 is not going to kill you and may just give you nausea.
Secondly its pointing to the fact that the 800 IU dosing is too low for the average public and the institute of medicine is way off on the standards of recommending a dosing for people. See the report of findings hear for IOM
Please get your blood levels tested, but you can still start at about 5 times the dosing that the IOM recommends before you do get tested within 3 months.
No one has died from an overdose on Vitamin D3 so please don't go from a fear perspective when you are wanting to use a vitamin as a health aid. Be responsible but we can on a sunny day produce between 10-20,000 IU of Vitamin D3 in our bodies by pure sun alone.
Be well,
Dr. Kozura
