I think doing an update would be great, when I have time. Just a note: the article you cited was not a randomized controlled trial. It is a meta-analysis that included only 2 small…

I’m the author. In reading the comments here, there are some common questions and misunderstandings that I would like to address. First, about the patient being an outlier: I wrote…

I wrote the article because I see cases like hers pretty frequently. She is an outlier in the severity of her symptoms, but not an outlier in getting Vitamin D toxicity from 5,000 …

Also, Michael Holick is a controversial figure. A lot of the articles pushing high doses of Vitamin D lead back to him. Please read this NY Times article for a great summary of his…

This is one case report. Yes, this person took an insane amount of Vitamin D and ended up very sick from it. But we can't really conclude that amounts under her dose are safe.

It's really important to follow the sources when you see something like this quoted. The article you link to is not an actual study in which people were given Vitamin D. It is a re…

There is a big difference between Canada and the US in how Vitamin D is treated. In the US, you can go into any major pharmacy chain like CVS or Walgreens and purchase Vitamin D ov…

Hey there! I'm here now and will try to respond to everything brought up. Some of the confusion stems from the complexity of the issue. There has been a lot of research on the clin…

I am a physician (specialty surgeon) in the US, so can comment from that perspective. Clinical documentation is often the bane of my existence, so there is definitely a need for in…

For example, the comment from Paul Gambill, the CEO of Nori who is quoted extensively in the article. He wrote in to clarify that he does not agree with the title and that he does …

For those interested in Vitamin D and Covid, here is a summary of the research so far: https://www.devaboone.com/post/vitamin-d-and-covid

I see Vitamin D toxicity at MUCH lower doses than in this case report. Here is my description of one patient: https://www.devaboone.com/post/vitamin-d-part-2-shannon-s-st... Most o…

The headlines on Vitamin D and Covid far surpass the actual data. Here is my summary on the latest research: https://www.devaboone.com/post/vitamin-d-and-covid

Which fields put names in alphabetical order? In medicine, at least, deciding who goes in the first and last name spots is a really big deal, and fights over this sometimes ruin pr…

The chart is only regarding RCTs. In the best individual trials that we have, it does not show a benefit for respiratory infections. But we do see some suggestion of benefit in met…

I don't think it is all due to sampling error. In my article I mention that one of the areas in which Vitamin D shows promise is with respiratory illness. I think there likely is a…

I wrote the article. It was very hard to write a concise article about all of Vitamin D research, and so I didn't have space to address it, though I really appreciate the feedback.…

I wrote the blog post. Unfortunately I was not able to include every study on Vitamin D, and had to pare it back to the largest and/or most significant studies. Most of the studies…

Here is what the article states: "Therefore, a multivariate logistic regression analysis was performed to adjust the model by possible confounding variables such as hypertension an…

I tried really really hard to put in all of the most significant studies on Vitamin D. Small, low-quality studies didn't make it in, but the major trials did.

I didn't watch the whole video but I read the study. There is a lot of excitement about this study, but the details in it matter. It was randomized - but when you look at the two g…

There is a lot of excitement about this study, but the details in it matter. It was randomized - but when you look at the two groups (treatment vs. control), they had some key diff…

That is a reasonable hypothesis. Also, people who are very ill are less likely to get outside and get enough sun, so they will develop low Vitamin D. Vitamin D is likely a marker o…

Thanks for the feedback. I will edit the article to specify that she was NOT taking any calcium throughout all of this. This is not uncommon - Vitamin D seems to be more effective …
