I have to say about vitamin D: after reading through a lot of the vitamin D wiki -- the link to which you posted on your site -- I applied the recommendations therein. I was, like almost everyone, severely deficient in vitamin D. After six months of what would be considered "aggressive" supplementation, I finally have enough vitamin D, and more, to not be deficient.

A curious thing I find online in American writings on vitamin D is that 30 ng/mL is the lower limit for sufficiency, but in my own country (Serbia) the recommended minimum is 75. I eventually achieved the value of 90 and something, in a relatively short period of time. All the while when I told my friends and family that I take a huge dose once every two weeks they were telling me it was super dangerous.

Not to be a smartass and an "I told you so" guy, but for real now I'm the only one with a healthy level of vitamin D. One doctor told me "excellent, how do you supplement", and when I answered he said "well that's kind of dangerous I guess but you showed it was fine".

My wife's aunt is a doctor of medicine and when we were discussing this I told her I've got a healthy level of vitamin D and how I got there, she said "that way isn't safe, vitamin D is the only vitamin that has a lethal dose". I don't know if this is true, but she is a doctor of medicine and I'm not an asshole to tell her "debate me I read wikis online", that's kind of idiotic and disrespectful imho.

I did not mean for this to be a "thanks for reading my blogpost", but I thought it reasonable to personally confirm the stuff you posted, and to thank you for sharing this. Getting those vitamin D levels up has had a significant impact on my health and managing my chronic illness. Your site is a treasure trove of information, keep it up!

If I can be totally honest, I find the lack of professional information regarding the idea that there is a very very high ceiling (or none at all) for Vitamin D, in fact most well-known and widely accredited sources of medical information, from Mayo Clinic to Cleveland clinic, as well as top college health departements like Yale and Harvard say the opposite. I think that this is definitely something (cont'd below)

that needs more reasearch done on in more mainstream sources before I fully jump on the Vitamin D bandwagon. I think it's a great idea to make a push towards getting more Vitamin D, I just want to make sure some more credible sources beyond an internet wiki and underground neocities page say its safe. I do plan on working towards the current professionally reccomended limit though!

I'm not saying you have no credible sources, the studies you cite totally check out, but there just aren't quite enough of them at the present moment to soothe my worries created by the sheer multitude of other widely regarded as credible sources suggesting otherwise. This is definitely something I will be keeping my eye on.

Additionally, taking a look at some of your citations on the Vitamin D section of your wikipedia unreliability section, you also seem to cite an awfully high number of sources that claim Vitamin D doesn't have that crazy of an effect at high doses as well as suggesting that the benefits of what are considered to be high dosages aren't nessecarily worth the risk at this point. Additionally, there's pretty much only

one study you bring up in this article that actually sings the praises high intake of Vitamin D, and as proven time and time again (see the artificial sweetners and bladder crystal rats study), one study ultimately doesn't mean all that much until additional ones are created that verify it. It comes across as source cherry-picking on your end, where you frequently cite the same singular source that shows benefits,

yet many more that warn of the consequences. To anyone else reading this, I would suggest to use caution in taking extremely high dosages of Vitamin D until we can be sure with additional studies, especially more modern ones past 2013, which is when the study Dig Deeper repeatedly cites. (although maybe not ones sponsored by the current US administration)

I genuinely don't think there's an ounce of malintent from Dig Deeper here. I don't want this to be viewed as an attack of any kind, I've got no beef, and would prefer to not start beef, I just feel like it's important to mention these things and be care things and urge the use of caution when in a place of authority, the authority being someone who writes informational blogs advising against ideas that have been

long-sustained. I believe long-sustained ideas should be challenged, that's how humanity advances, it's how we do better than our past, but we need to make sure we have enough varied evidence before we start pushing back against what medical professionals advise. Especially on the internet, where a huge portion of people are willing to blindly trust someone who sets themselves up as credible.

I like that you mentioned questioning long sustained ideas, because I was surprised that at vitamin D wiki sources about a certain topic are sorted in reverse chronological order, i.e. from most recent. Very useful for checking on new findings concerning its effects on something specific. For me personally I check the epilepsy and asthma sections.

I'm also a fan of how Henry -- the man behind vitamin D wiki -- is actually simply amassing sources instead of interpreting them. In his about us page he writes some personal opinions, mentions where vitamin D looks promising but needs more proof, etc. etc. etc. Pretty cool guy imho.

https://pubmed.ncbi.nlm.nih.gov/27114973/ apparently when I tried to post this link the last digit, 3, was dropped and the article linked was "child abuse and lack of care in denmark". So I deleted my previous comment to post this one. This is the actual link to the article discussing safety of high vitamin D supplementation.

Great article. Besides being informative, the uniqueness of it shows how effective propaganda in spreading the Us vs. Them mentality. Most obvious in the US where there's literally two parties, it's like a football game. Thanks for posting, great, informative stuff as always.
