Because the D on its own, yeah, it didn't show any effect.

But sun exposure.

It seems like it only helps people who are really deficient.

Like if you're super low, like below like 16 nanograms per milliliter, then probably it's a good idea.

But like for people who already had like at least 20 nanograms per milliliter, it didn't seem to have any of these benefits that they were seeing in people who naturally had high rates through sun exposure.

The way you're looking for it.

Yeah.

So that's going to be for people who have super low levels?

Yeah.

So they had thought that it might reduce...

instance of all these other diseases based on what they're seeing for people who naturally had high levels through sun exposure and it didn't um so then people who had high levels through sun exposure yeah so because your your natural level of vitamin d is sort of a direct like meter of how much right but this is a natural level you're not talking about supplementation right right okay so that was why like people who had high levels of d without supplementation have lower rates of all like every disease you can think right

So the hope was that raising everyone's D to those levels would have the same effect.

And it didn't.

Like the New England Journal of Medicine actually did an editorial in 2022 saying, stop prescribing D, it doesn't work.

He didn't look as good as you, right?

Doctors, yeah.

I'm amazed how poor...

What poor health they generally seem to be displaying.

Yeah.

I noticed that when I started going to all the conferences of the sun researchers and they're all in like the basements of hotels and those guys all are as pacey as it gets.
