I agree mostly.
Vitamin D3 actually is a signaling hormone that is involved in the modulation of cytokines. Oral vitamin D has not been shown to be much benefit in a hospital setting where a person is already very sick because it takes the liver in the body several days to convert vitamin D3 to the form the body actually uses. Also by that stage of the disease the liver is not doing a very good job of conversion. Direct injections of colciferol(sp), the active form, has been shown to be helpful in treatment but has to be done through an IV.
The take home is taking vitamin D supplements needs to be done before getting sick to be of much benefit. Vitamin D 25 hydroxy at levels above a minimum of 40 are desired. 60 going into winter months better. Wife and I tested 75 last month. Up to 100 is fine and I am unaware of any problems at levels even higher. We take about 8,000 IU's a day during winter months along with vitamin K2.
