Natural Vitamin D-Levels

Vitamin D is still quite a mystery to me - So here's an update on what's been happening to me

my levels used to be really low (last autumn around 40)
then I took Vitamin D as a sublingual spray and my levels skyrocketed
and even after I stopped taking it my levels still increased (up to 230 at the last test two weeks ago)
that's of course far too high

But what I have noticed doesn't seem to be such a bad thing at least at first glance:

 

a huge change in my circadian rhythm:

 

I used to have problems with sleeping, I only managed to go to sleep around 2 am and woke up 3-4 times a night. Now I get so tired, not the sickly exhausted CFS feeling, but real overwhelming genuine tiredness, that I go to sleep just before midnight and sleep until eight with just one or two interruptions. And it makes a small but noticeable difference: I have more 'good' days. Meaning that on the CFS ability scale I'll be a 3 instead of a 2 more often.

 

But this happened only when my levels went over 200.

The usual opinion is that optimal Vitamin D levels are between 60-80 or 60-100 at most.

One German guy, Dr. Gesswein gives values from 180-230 which seems oddly high.


So I searched the net for 'normal' levels and finally found an article on 'natural' levels here:

Natural Levels of Vitamin D

 

Sunlight = Vitamin D: Humans make 90 percent of their vitamin D naturally through sun exposure to the skin (without sunscreen). In Canada‚ our northern climate means UVB levels in sunlight are too weak 4-6 months of the year to make any vitamin D naturally.

What is the intended, natural level of vitamin D that the human body was designed to operate with?

Humans evolved in the horn of Africa, close to the Equator over 30,000 years ago. They spent their days out in the full sun, with no clothing, hunting and gathering food. Their skin pigment evolved and protected them from sun burns and allowed the production of vitamin D through the skin. Nature never intended for humans to live and work indoors, in cubicles, without sunshine exposure.

Grassroots Health and over 40 Vitamin D Scientists recommend achieving an optimal Vitamin D level for disease prevention of 100-150 nmol/L using a 25(OH)D blood test. This is the natural levels that the human body had as it evolved over thousands of years. Everyone should have their vitamin D 25(OH)D blood serum levels tested and make sure they are within these guidelines.

So maybe the D-levels should be a lot higher than the mainstream 60-80 recommendation

I however will try to get my levels down to under 150 asap hoping that the benefits of my circadian rhythm change will stay with me.
