Study finds vitamin D provides significant protection from covid

Also you generally only need to be in the sunlight 30 minutes a day to maintain regular levels of Vitamin D. It's not like you have to be a day laborer toiling away outside for 8 hrs a day.

this is interesting. I know there has been talk about this for a long time but we know correlation/ causation often does not line up. this is good news indeed if studies are showing vitamin d to be be an effective therapeutic.

this kind of thing never seems to find a way into the mainstream for whatever reason

Thanks for the info! I’ll be sure to take some D every morning!

op, what brand do you use? I know some of these otc supps are often bereft of what they are supposed to contain

I agree vitamin D3 supplementation makes sense. What you say is accurate but could also be misconstrued. The study has nothing to do with preventing Covid, only about the severity if you do get it.

“Our study contributes to a continually evolving body of evidence that suggests a patient’s history of vitamin D deficiency is a predictive risk factor associated with poorer COVID-19 clinical disease course and mortality”

"Stay inside, stay home." Better either move them goalposts again of label another truth as MISINFORMATION! Liberalism is the virus.

True, during summer months. It doesn’t work the rest of year. And, wearing sunscreen, greatly reduces your body’s ability to make vitamin D.

Same with turmeric: https://pubmed.ncbi.nlm.nih.gov/34122090/

1. Scientists skeptical of vitamin D have argued that covid low D levels might be caused by the covid infection itself. This study challenges that claim by looking at D levels prior to infection.

Do you have a citation for this? My understanding is that it has been broadly accepted for years that low vitamin D levels negatively affected immune function. In that context this result is unsurprising.

Previous studies I've seen have looked at the utility of vitamin D supplementation as a post infection treatment and found it wasn't particularly helpful. This also is unsurprising since a chronic vitamin D deficiency isn't immediately improved by supplementation.

See if you can find it on, oh, I don't know, CNN.

Because you can. But just keep on repeating the same tired old trope that mainstream media doesn't want you to know the truth.

Scary that someone so out of touch with reality is a high school coach.

Good.

Now, what correlation is observed for those with low preinfection levels of antibodies against Sars-CoV-2?

Ignored by the media but this has been known for a while. When I got covid last summer, the doctor told me to take vitamin D and zinc

Don't let the perfect be the enemy of the good.

If all you can get is 30-45 min during the winter when you're out on your run, that is still better than nothing.

The main focus is that "Getting outside in the sunshine is Good. Staying cooped up inside is Bad."

How would you know that since you’re so fond of claiming you don’t follow the mainstream media? A quick search shows they did cover it.

You are correct. I was posting that "I" had been posting on the preventive (and therapeutic) effects. This study doesn't address preventive effects at all.

There are observational studies of countries and cases that indicate a possible preventive effect of about 24%, IIRC.

I subscribe to a service that tests supplements for purity, quantity, and so on. My first choice is always Life Extension. After that, it's Kirkland (Costco Brand). There are 3-4 other brands that are always in the Recommended category, but I stick to those.

The people I follow recommend D3 plus vitamin K2 to improve absorption. In my personal experience, 7,000 IU D3 plus K2 (Life extension brand) gave me a D level of 82, whereas a 12,000 IU (Kirkland) without any added K2 gave me a D level of 59. When I temporarily went to 20,000 IU (Kirkland) without K2, my D level was 95. Note: These readings were after 6-8 months of dosing.

Make of that what you will. I'd recommend that you tell your doctor that you are taking large doses of D3 and request a D test whenever bloodwork is drawn. Doctors will be concerned about overdosing and will probably authorize testing. The reality is that overdosing on vitamin D is extremely rare, but it can cause kidney stones so you have to take potassium citrate to reduce that risk. There are no double-blind peer-reviewed (Big Pharma funded) FDA studies to prove any of this, so caveat emptor!

Can you share links to these observational studies?

Whilst I am a fan of Vit D3 and take ~4,000 a day, I'm not sure this study is anything new.

The problem is knowing if the low Vit D levels are related to why Covid would be more severe. I.e if a person is obese or old, they will likely have low d levels. Now, is the severity down to the fact they are obese, or that they have vit do deficiency.

Really it's a crime no one has done a proper study on this (there's a couple of very small ones, but nowhere near enough).

Yes better than nothing, but still much closer to nothing than the daily standard during winter months, particularly if you are above 35 N (or below 35 S) latitude.
