Please find the link because about 2 / 3 months ago there was a story that was exactly the opposite finding.

I've been monitoring HN for Vitamin D info very closely.

I think the parent poster is referring to https://www.medrxiv.org/content/10.1101/2020.11.16.20232397v...

(Can't find the HN discussion link at the moment, unfortunately -- it didn't point to that particular link!)

Worth noting that this RCT was for bolus supplementation of Vitamin D3 at some point in their hospital stay, and excluded patients already supplementing with D3.

This study stands in stark contrast to the earlier pilot out of Spain: https://www.sciencedirect.com/science/article/pii/S096007602... -- though as noted, this was not D3 but rather Calcifediol (a D3 metabolite), and a much smaller study.
