An interesting fact about vitamin D is that it’s actually a pro-hormone (nuero - steroid) and it’s considered to be a nutrient not a vitamin.
The cost of it is nothing if you get it directly from sunlight and oral supplements are reasonably priced. It is made by bathing lanolin in ultra violet light.
Sunlight is the natural way for the body to manufacture it and it’s virtually impossible to produce excessive levels this way.
However, to get it directly from sunlight presents a challenge for those of us living in northern regions like Canada. One way is to use a sun lamp but the most common way is oral supplements.
It’s important to determine your required therapeutic level and to monitor those levels to see they are achieved. It’s undesirable to be too far below or too far above the recommended levels.
Testing is important because overdosing with it can produce elevated levels of calcium, meaning that it is not being absorbed properly.
The best supplements are not in foods because they are usually the wrong kind for the body to use effectively.
So, because abundant sunlight is impracticable for most of us (in the north), the recommendation is oral tablet supplements and the monitoring of levels in the blood.
I believe in the therapeutic benefits of this supplement That's only because of the amount of independent, un-biased information and advice there is circulating in the media supporting its importance.
I spend a lot of time in the sun in the Canadian summer, mainly whilst golfing. I do develop a tan and I make sure I don’t ever get sunburn.
For the times when my shadow is longer than me, I will increase the amount of the vitamin I absorb by the use of oral supplements.
For any period of time I go down south for the winter I will cut back on those supplements.
The next time I go to my doctor for an annual check up I will find out the best way to monitor the levels in my blood and compare that to the recommended levels of vitamin D.
