Vitamin D is a not a vitamin but a secosteroid.
Whatever the memeStream pushes you have no evidence, vitamin D supplementation helps nor does it have to do with all over health.
Vitamin D has multiple inactive forms such as:
>Cholecalciferol, Cholecalcidiol, ergocalciferol etc.
And on ACTIVE Version which regulates inflamation and is never measured:
>calcitriol

They measure resevere Vitamin D. Never the active.
If "Reserve" is low, they declare you as defficient, even though it is converted to calcitriol and activly used by the body.
The Vitameme causes people to supplement steroids which actually harm them.
Because they believe Youtube Podcast gurus and headlines of Popscience magazines.
Nutraceuticals are a meme.
And Vitameme D is a also a meme.
Nobody reads the science.
Everyone falls for Youtube Podcast memetics.

Kek.
Don't you know that vitamin D is also a steroid?
And not a vitamin absolute kek.

You have no Idea how retarded Vitamin D supplementation actually is.

Just want some information on the "so called" Vitamin D.
I know and it is known that this is not a Vitamin, but a steroid made from cholesterol.
It is not a "essential" Vitamin, because you can make it yourself.
But currently the push for oral and IV supplementation is quite odd.

I know some Meds, who never believed in any supplementation of any vitamin up until 1 year ago.
And now they all of a sudden switched sides, especially on the topic of vitamin D.

So I did my due diligence, and read a shit ton of Vitamin D studies.
Which oddly don't show anything beneficial.
Not even in their conclusions.
Not only that, they claim quite the opposite.

Vitamin D or to be more exact the orally consumed cholecalciferol is a pre metabolite of calcitriol.
cholecalciferol is a inactive version of the active steroid hormone calcitriol, which works like a cortiocosteroid.
It supresses symptoms.
Not only that, in the Lab measurements, they only measure for the two inactive versions of Vitamin D: cholecalciferol and Calcifediol and never the converted active hormone calcitriol.

So the big question is, what is the implication of adivising people to increase their Vitamin D, if it is mostly converted to steroids?
And how did people came to conclusions that oral supplementation is actually helping?
And if people are inflamed, they are low in cholecalciferol and Calcifediol. But whit if due to their condition it is converted into active calcitriol, because they have inflamation and it is to regulate their inflamation?
How do we even know anything about this, if it is never measured.
