Yes, I agree that the sun is the best source of D. In fact, there have been some questions as to whether taking supplements somehow makes the body’s natural vitamin D production from sunlight less effective.
However, the MDR amount of D (400 IU) is now thought to be way too low and will probably be increased by the “experts” soon. I don’t think that 2,000 IU a day would cause problems with toxicity, but everyone does need to be aware that we can OD on D. ;-)
There are simple finger prick home blood tests that can be ordered online to test for levels of D.
Fat soluble also means that you need to ingest fat at the time you take the supplement for it to be properly absorbed.
My intake is now 3,000 units, down from 4,000 and a temporary spurt to 6000 during the month when there was flu present. At levels above 2,000 units a day, the hacking and coughing every morning to clear my chest disappears. The mucous flow is altered somehow.
In June I had a kidney stone, out of the blue with no warning and no known proximate cause. When reading on the subject, there was one one glaring possible kidney stone cause listed...... excessive Vitamin D.
Does anyone know of the relation of Vitamin D and Kidney stones?
As a Diagnosed Type 2 diabetic, possibly prediabetic depending on who you believe, the intake of Vitamin D would seem to have no effect on my condition
