Seems factual, but raised my eyebrows a couple times. Comparing Vitamin D to steroids is completely gratuitous. Sure, they're structurally similar, but so are oxygen (O2) and Ozone (O3). Have you ever tried to breathe Ozone instead of Oxygen? From the previous article: > Unfortunately, we do not have a full unified explanation for how Vitamin D deficiency could lead to the list of diseases that are associated with it. We know the correlations are there, and we can show that the Vitamin D molecule has an effect on multiple cells and organs. So if you are deficient (as most adults are), you should take Vitamin D to avoid those. It's irrelevant that we do not know pathways. This probably suffers less confounders than other health issues, because Vitamin D comes from the sun. But in this article: > A few readers have made comments like this: “I understand that the evidence for Vitamin D in healthy adults doesn’t really show a benefit, but I take Vitamin D because it probably won’t hurt me, and it might help.” This is a common sentiment regarding supplements, but not a statement that most people would make about metoprolol, or any prescribed medication. It's hard to see how this sentiment isn't exactly correct, at least if you're deficient. Remember, most people are, so if you don't go outdoors a whole lot, you probably are. I'm also surprised Vitamin K isn't mentioned. I take Vitamin D, but I've heard the standard advice is to always take Vitamin K in addition, which helps to regulate Calcium and avoid the issues described in this article.
