Well here is a new double blind RCT on vitamin D, or better Calcifediol:
Especially in the 7-14 days time there is a clear advantage. 160 patients overall. Of course most people would be way better off, had they had high vitamin D levels when contracting the virus. way better to already have 50ng/ml serum levels before getting infected as only reaching it a week later. And those people in the study were mostly overweight/obese.
A post-hoc composite of three respiratory symptoms (trouble breathing, chest congestion and dry or hacking cough) resolved 3.0 days faster when 25D was elevated at Days 7 and 14 (p<0.05); chest congestion resolved 4.0 days faster with 25D increases of ≥25 ng/mL (p<0.05). Safety concerns including hypercalcemia were absent with ERC treatment.
Conclusions and Relevance ERC was effective in increasing serum 25D in outpatients with COVID-19, which may have accelerated resolution of respiratory symptoms suggesting mitigation of COVID-19 pneumonia risk, findings which warrant further study.
There are tens of thousands of papers linking Vitamin D with everything under the sun.
That’s no surprise because vitamin D is a vital molecule for us to function .There’s a bit more nuance to it as well because Vitamin D is actually a collection of similar molecules.
However HOW it is linked to any given disease (is it a symptom rather than a cause or is it simply statistical noise ) is a different story and WHETHER supplementation could improve the situation is another complete story again !
Something very important to understand. A lot of researchers want to show a link. There’s less interest in proving doesn’t have any link (yeah we knew that already it’s a dead end is this even worthwhile publishing ) compared to saying hey look I found something linked , let’s investigate further, (aren’t you clever and here your publication which you knocked together from a months work )!
It’s the easiest kind of research you can do to be honest. Do some vitamin d level testing in blood and take medical histories of patients over a time course.
That’s why above I linked an double blind study. Clearly showing faster resolution or illness.
And there were already enough other Supplementation studies showing great effect, though mostly non blind.
The fact that most people dying or covid 19 are severely deficient already prior to infection is well known and not disputed (the question is only can Supplementation help or not).
I didn’t say anything about it being fake or whatever.
I’m telling you how clinical research often works.
Also non profit doesn’t mean a lot. It doesn’t mean that commercial operators aren’t sitting behind them. Which I suspect is very much the case for this society too.
Look up the story of Purdue Pharma and how they worked with ‘non profits’ to advocate for them.
A nice way to make yourself some profit in the back pocket is to open a non profit and pocket a massive salary and luxiourious expenses paid lifestyle . I have often day dreamed of doing that.
The first double blind parallel randomised study to vitamin D with a good design is out, prevents 75% of infections, so way better than the vaccination!
It exactly confirms my point that the vitamin D addition to many food products in Taiwan is the real reason how Taiwan could avoid covid for so long and why it will be here like in Norway:
And yeah while the virus of course can adapt to vaccines, it most likely cannot adapt to better immune system by vitamin D.
Now sadly Taiwan is not supplementing around 4000 IU per day but rather 1500. But that explains perfectly why it could stop pre Delta, had a hard time with Delta and is now not possible to stop omicron. Assuming marginal gains on increasing supplementation 1500 IU will halve the infectibility. With an R of 2-3 for Delta that worked and with 4000 IU most likely Delta could not even spread without any other protective measures. As it developed to omicron it’s not enough. But it will very surely prevent a lot of severe disease as shown in other studies.
Remember Taiwan and Norway have the highest vitamin D serum levels of any country worldwide.
No there isn’t but the vaccination right now prevent nothing much at all except for old people with co morbidities. It certainly doesn’t achieve 75% reduction in infection. Plus it has loads of side effects while 4000IU of vitamin D is absolutely safe for adults with no negative side effects. It’s the recommended dosage for supplementation without actually testing vitamin D serum levels. It’s well below 10.000 IU per day where you run into a decent chance of having negative side effects (not likely but clearly outweighted by the benefits Vs 4000IU)
Many, go into a 7 and look at the ingredients. Mainly convenience food. I was really surprised at the amount because it’s the only country in the world where I found products with vitamin D added . The Scandinavian countries don’t declare it as it’s added by default to mild and or flour. Taiwanese avoid sun like the plague yet after Norway it’s the country with the lowest amount of deficiency, it can only come from the food.
Sunlight - Vit D is free (but of course you can take supplements too)
Direct sunlight is a great way to increase your Vit D - makes one suspicious why everyone has been restricted from going out side (globally not specifically Taiwan)
It’s pretty well known, 1000IU in food per day increase the levels for an adult on average by 10ng/ml. But yeah it could vary by up to 50 percent. So some people only need 2000IU while others would need 8000IU per day without much sun on your full body (that one again is easy, may you fan get by sun with full body sun bathing without sunburn is 20.000 IU. Now if you walk outside with only your forearms and face in the sun, how much percentage of body surface is that? Well not much. Plus it’s about how close did you get to the max your skin can handle without sunburn?
Ideally you want to be around 40-60ng/ml D serum levels. That’s the level of indigenous peoples before getting in contact with civilization or of apes.
It doesn’t matter if you consider that easy or hard. But yeah it’s hard if you consider how much food without supplements has in vit D. you would need to be eating salmon only so to say to get 4000IU per day.
Meaning without supplementation your food is not going to play much of a role. Sun only increases your vitamin D Levels if the sun is over 45 degrees angle. So forget any morning or evening sun. Or winter time in northern/southern countries. Even Taiwan in December not much chance outside midday
. I have often day dreamed of doing that.
