PN--interesting paper.
Vitamin D is an important part of the endothelial health program for this very reason---
because low levels damage endothelial cells and increase oxidative stress, damaging the vasculature. There's a lot more research since I put it together--this was the paper I cited in '08 ( Effect of vitamin D replacement on endothelial function and oxidative stress in vitamin D deficient subjects. Endocrine Abstracts Vol. 14, 275)

Here's a thread on the Coimbra protocol, higher dosages.

Funny story. Turns out I was severely vitamin D deficient... 17ng/ml (!!)
I decided to go see the doctor and get a bunch more testing done--and she's prescribing 50,000IU D3 once a week (now my 6th week) with calcium, mg and zinc.
My arthritis pain levels went from 9 to 2. I had no idea pain levels were affected by D.
Irony is, Jeff is tested regularly, takes appropriate supplementation to stay in range, but I'd never been tested. I'm outdoors all the time, in so cal, I eat well, so I figured no problem.
Wow. Lots of stuff can affect D metabolism--low mg, age (I'm old) food allergies (turns out I'm allergic to gluten), and a bad micro biome (I was missing a bunch of good bugs). I'll be retested in a few more weeks, will post new level.
Now I'm on the endothelial health program, too. I'd spent the money just on Jeff's supplementation...thought I was OK. Proof that even "healthy" people should be tested for nutritional/vitamin/bacteria levels, and can benefit.
doh! I'm eating crow.
