Hi, I'm the wife. High dose Vitamin D can cause elevated calcium levels (meaning over 10.0 mg/dl for adults over 40, it can be a little higher for younger adults). I usually don't see that occur with doses at 2-3 K IU daily. You can also check your Vitamin D 25-OH levels (the level that will be done if you just get a standard "Vitamin D level") and these should be in a reasonable range. What constitutes reasonable ma…

Would you still consider 5,000 IU of Vitamin D per day safe as far as these calcium issues go? I had a doctor tell me to take that dose for at least a few months a few years ago after low levels in my bloodwork during the winter. But I've never known if I should lower the dose to take on a continuing basis or adjust during the summer when I get a little more sun (but I still work in an office/at home so spend a lot o…

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…

Although this is a notable finding it's important to remember that it doesn't lead to the conclusion that supplementing vitamin D will be very beneficial here. When vitamin D is produced in the body naturally via exposure to sunlight there's a huge amount of other things that occur as well, and we don't have a ton of good science to back up if curing a vitamin D deficiency via supplementation of pure vitamin D is rea…

Would you mind elaborating on what you mean by "wacky" levels? I can't tell from your comment if that means high or low. Asking as a Vitamin D supplement user who uses 2-3k IU a day

What about 60,000 IU/week for someone who had D,25-OH at 7. I did that for a few weeks. Now I am up to 44 and switched to monthly. It's a singel 5ml dose. You just drink it once instead of taking it every day.

I just spent a few minutes surfing her blog, and she actually has a really good answer to questions along the lines of "What do you think of study X?": https://www.devaboone.com/post/evidence-and-intuition-in-the...

No affiliation, not a doctor, etc., just thought this particular essay was well stated.

What brand/strength of VitaminD supplements do you all take?

I take 5000 IU D3 a day, in a pill that combines 180 mcg of K2. K2 is important for calcium transport. My most recent tested level was 38 ng/ml. I'd like it to be above 40. I also make sure to get a lot of sun, because I think the measured benefits of D3 blood levels might be partly a proxy for sun exposure. A good resource for managing your serum D3 is https://www.grassrootshealth.net

I do similarly. The k2 because I read it can be extra important if you have a history of kidney stones.

I do see people get high calcium levels after being on this dose for years. But not always. You may be able to handle that dose. If you are getting "routine" labs done, then there is likely a calcium level in there. If your calcium is normal (under 10.0 mg/dl for adults over 40, younger adults can be a little higher), then your Vitamin D dose is ok... but I would still recommend coming down a bit on that dose. It is…

A couple of questions if you don’t mind.

What are your thoughts on the research about low Vit D being caused by inflammation as opposed to the reverse?

Also any thoughts on what form of testing works? Seems like many things tested often have variations that are not routinely tested for.

My autoimmune disorder was initially diagnosed via positive responses to antibiotics. Normal testing confirmed it later on, so I’ve been highly interested in some of these unusual approaches.

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…

People in my doctor friend's hospital taking HCQ got arrhythmias at a higher rate and often didn't get better. It is not a miracle cure and is quite dangerous in the alleged "treatment ranges".

I am a bit stunned that people are still going on about HCQ after all this time and the many trials. I feel this comment by a virologist is the key to understanding why it got so hyped and is not working:

https://www.sciencedirect.com/science/article/pii/S016635422... (May 2020)

"Highlights

• In vitro data suggest that chloroquine inhibits SARS Cov-2 replication. • In past research, chloroquine has shown in vitro activity against many different viruses, but no benefit in animal models. • Chloroquine has been proposed several times for the treatment of acute viral diseases in humans without success. • The outcomes of some current clinical trials of chloroquine in China have been announced, without access to the data. • Peer review of the results and an independent assessment of the potential benefit for patients are essential."

"average age group of the 20 patients" == 60 years old Is 20 a high enough sample size for any meaningful conclusion from a study like this?
