Vitamin K2 does help bones absorb calcium, but it will not prevent the blood calcium level from rising if you are really taking more Vitamin D than you need. This is simply wishful thinking.
Is vitamin K safe to supplement? Or does it mess with the blood clotting? People recommend really quite doses: K2-MK7 at 100 to 200mcg, or alternatively K2-MK4 15 to 45 mg (not mcg).
This article is (badly) written by un-qualified authors (two software developers). This would be enough to raise at least a few red flags on the conclusions drawn here. Has it even been peer reviewed? From a first look, there no way this work would have been published by any reputable journal. If there is any truth in what the authors claim, the best they could do is to work with field experts and/or submit their fin…
> This article is (badly) written by un-qualified authors (two software developers) Indeed the first sentence talks about "corona deaths." No qualified medical professional would write that in a paper.

What is a “not low dose” of vitamin D? Would 5000iU a day still be low? 10,000iu? Is it really possible to have enough vitamin d exposure just from diet for someone who lives in a northern state which doesn’t get nearly as many sunny days as a place like florida or california?
5000 IU is high dose. 10,000 is really high. A more moderate dose would be 1000 to 2000 daily. If you live in a northern state, your Vitamin D level will vary with season. And with increased use of sunscreen (which is a good thing), it can be hard to get enough Vitamin D. I'm not opposed to anyone taking Vitamin D (I take it actually). I just want people to take it in moderation unless there is a very clear reason fo…

Sorry about the rate limiting! That's a new-account issue, and I hate that it affects perfectly legit new accounts. I've switched that off now, so she can post freely.

This conclusion (10x higher mortality if deficient in Vitamin D) is rather significant. How trustworthy is this source?
From a technical writing style perspective, the thing going against this paper is the folksy way of writing. It also includes things called weasel words, such as saying very young doctor, versus young doctor, or even just doctor. The results are compelling, and I suppose it would not hurt to take a prophylaxis of vitamin D (5,000 units per the article?) as compared to a prophylaxis of something else, such as hydroxyc…

What about this section of the pdf? From a 2016 study on patients with other respiratory diseases. —————- High dose vitamin D administration in ventilated intensive care unit patients: A pilot double blind randomized controlled trial In the study, patients with vitamin D deficiency ( https://www.sciencedirect.com/science/article/pii/S221462371... —————— Ah, the pdf has a second such study. Mortality almost half less…
Also see this letter by Dr. Gerry Schwalfenberg. It's just an anecdote but his claim of success in treating influenza patients with a "vitamin D hammer" is interesting and should prompt additional research. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4463890/
However, that’s a bit hard to remember so I always have extra on hand. When I have a cold coming on a take a large(r) dose and it certainly seems to help.
I've mentioned this before, but my wife is a parathyroid surgeon (parathyroids are the glands that regulate the calcium in your neck) and would beg you to PLEASE monitor your calcium levels if you are supplementing with Vitamin D. She often sees patients on high doses of Vitamin D from well intentioned doctors, but with out of whack calcium levels because of it, and the patients can be very sick without understanding…

What was your daily IU supplementation, and how long did you supplement before checking your levels again? I take 5000 IU daily, but also wonder if I'd do better with more sunlight instead.
I was taking 50000 IU a week. Checked multiple times over periods of months.
I've been very frustrated in my attempts to raise this issue with the local health department where I live. I was brushed aside, and was told "correlation does not imply causation". I doubt that the person on the phone wanted to get into a conversation about dynamical systems or nonlinear data analysis, so I didn't even go there. Instead I sent a letter full of references to published research, and citing other lette…
Vitamin D has been endlessly promoted as a treatment for many diseases due to evidence from observational studies, but hundreds of millions of dollars in randomized controlled trials have never demonstrated it to be effective for any disease except rickets. There was just a large trial published in JAMA [1] examining its effectiveness for depression given solid observational data. It was not at all effective. The rea…
But vitamin D almost certainly does help with certain conditions. For example, I have psoriasis and can develop awful (painful, itchy, ugly) plaques on my knees and elbows, as well as painful skin nodules on the palmar surfaces of my hands and feet and dandruff. I had seen a dermatologist who prescribed some cream that sort of worked, and she recommended I expose the surfaces to 15 mins of sunlight a day. Those kind…
Also curious, is it possible that the 15 mins of sunlight per day was the actual cure, rather than the supplements?
