Hello everyone. Dr. Chris Martinson here, CEO of Peak Prosperity, and turns out vitamin D saved a lot of lives, or it could have, if only we'd used it.

There's a new study out. We're going to look at this because it's pretty definitive now, and I'll tell you why.

Mostly because they tried really, really hard to show that it didn't have an effect,

and it still had an effect anyway. This is how science works in our modern era. So let's go there.

Here's the paper that just came out. This made a bit of a splash recently. It's on the,

get my drawn tool out here. The protective effects,

our effect, should be effects, I would bet. A vitamin D supplementation on COVID-19 related intensive

care hospitalization and mortality, definitive evidence from meta-analysis and trial sequential analysis a lot of

names here and so what did they do here well and again this came out just here in january

of 2023 so what did they do they went through a lot of this is a review so they went through a lot

of other studies pulled them together and did what was called a cochran analysis to get the best data out of them they can. Sometimes you can pool data from studies that otherwise didn't achieve statistical significance because they're too small. Pool it and you can still find the signal in there. Sometimes that works, but we've seen how this has been used to also, in the case of IVM,

do we see also how this has been used to find the opposite result from the one maybe they should have.

So here's what they did, methods.

They searched four databases in September of 2022.

Two reviewers then screened all of these papers and they assessed them for risk of bias and all that other stuff.

This is kind of interesting.

Results, we identified 78 bibliographic citations.

After the reviewer screening, only five RCTs were found suitable for our analysis so they chucked out 73 like

don't want those so there's a well let's hope there wasn't any selection bias in this

they performed a meta analysis the vitamin D administration results this is the punchline here

in a decreased risk of death and ICU admission.

Standardized mean difference here of 0.49. So about half. Half vitamin D administration. So this is
