Re: Vitamin D reduces incidence and duration of colds in those with low levels
#112Most vitamins are a waste of time and money, some are even harmful[1], but there are a lot of people with D deficiency, especially in winter[2]. 1 https://www.mdpi.com/2072-6643/17/17/2744#:~:text=highest%20... 2 https://www.abs.gov.au/articles/vitamin-d#edit-group-image--...
How do you feel about vaccines and Tylenol?

#113Heh...this is a shady study if I ever saw one. -- Exactly 400 study participants recruited. -- Exactly 193 of 200 participants completing the study in each group (which, for a study administered in a community setting, is an essentially impossibly-high completion rate). -- No author disclosures -- in fact, no information about the authors whatsoever, other than their names. -- No information on exposures, lifestyles,…
In the PDF they are all titled as
"Assistant Professor, Department of General Medicine, Arundathi Institute of Medical Sciences, Dundigal, Medchal Malkajgiri, Telangana, India"
The 2nd author is listed here: https://aims.ac.in/general-medicine/ I did not find any trace for the other two authors (do they exist?).

That's relatively fast but also the paper is not super in-depth.
And in general it seems like that the "International Journal of Medical and Pharmaceutical Research" is not quite well known. See the Editors, not even pictures there: https://ijmpr.in/editorial-board/

#114Anecdotal but when I'm sick I double my vit C and D intake which typically helps me.
Same... In our family we start taking Emergen-C a few days before we travel also.

The issue I've found with these discussions is it appears there's mixed evidence on if vitamin D *supplementation* actually has a positive impact, regardless of vitamin D deficiency. In other words, is the deficiency causal or correlative. I have no opinion on the matter, and am inclined to think there is at least some positive benefit. But YMMV
The problem is that vitamin D doesn’t absorb the same way for everyone. If a 100 people take 50IU of Vitamin D, you get 100 different results. Some get enough from minor sun exposure and maybe eating a fish now and then. Others need massive doses to get any results.
If your doctor is not seeing results they’ll keep upping the dose and I’ve heard of some that sound like an attempt at assisted suicide. Most of us would get toxicity from some of the ones I’ve heard.

#116I was pretty sure we already knew vitamin D deficits dampen the immune system.

Indoors best invention since fire.
Doors are such an important invention that multiple unrelated animals have evolved modified body parts to serve as doors to burrows¹. Being able to store food is critically important for surviving low-food periods like winter without migrating. "Indoors" lets you store food without insects or other animals getting to it & stealing it. Fire allows for hardening clay, which lets you make a special tiny "indoors" called a "pot" for storing food. Also bricks so "indoors" can be made anywhere. With a roof the rain stays out & you can stay dry & warm, and not freeze at night. A significant portion of why fire is so important is it enables creating various sorts of "indoors".

While I find your comment enjoyably pithy, in the case of vitamin D, many humans are currently living at latitudes which they are not suited to (skin being too dark to generate enough vitamin D given the insolation), and eating diets which do not provide them with sufficient amounts of it (the carnivore diets of Inuits and similar groups being a good contrast).
It’s criminal that the US sent Somalian refuges to live in Minnesota. Those are some seriously brown people in the land of no vitamin D. Pretty big population in Seattle as well, which is worse due to cloud cover.
Minnesota, not Wisconsin. Same latitude and a fair point.

I knew it was Minnesota, not sure why I wrote WI.
