For reference: The level of toxicity listed in your link is 60,000IU per day. Fauci said he takes 10,000IU per day. The bottle I purchased recommends 2,000IU per day. Get your blood work done people.

I always see Americans (apologies for making assumptions if you're not) throw around blood testing like it's something trivial and casually done. Here in the Netherlands, it takes a real medical indication and some pushing of a doctor to get any testing done. Alternatively, you use a private testing company that costs 200 to 400 euros for a comprehensive screening. Question to the public in various countries - how ea…

In India, Its pretty easy to get various preventative tests done. As for as prices, its cheap enough for engineers but non-trivial sums for a majority of the population.

As an example here's a list of all the tests, prices that a diagnostic center chain in South India provides https://appointments.aarthiscan.com/#/city/Bangalore/select-... https://aarthiscan.com/test-package/preventive-health-checku...

The test for Vitamin D is about 16EUR and comprehensive blood screening starts at 18EUR

There's an expert that specializes in vitamin D toxicity cases and regularly posts here. She sees cases at less than the 10000IU daily dose Fauci takes. I would be hesitant to go above 4000IU daily without monitoring blood levels every six months or so. Its winter here in Canada, I'm taking 3000IU per day. I drop that to 1000IU in the summer. I'm not a doctor, not recommending you do the same. Just sharing.

Just sharing too: I was taking 3000IU per day like you and noticed really positive changes to my mood and general wellness by increasing to 9k (my pills are 3k each).

But since seeing the alarming articles on HN I reduced a bit, and I'm thinking of getting my blood tested.

My sister got leukemia while part way through her doctorate. After it went into remission, she was unable to recall new information long enough to read papers and had to put her studies on hold. Eventually a doctor did a blood test that included vitamin d levels, and she was in the single digits (don't remember units but it was supposed to be at least 20). She started supplementing and graduated this spring. Just one…

The interesting analogy Ross Tucker (https://sportsscientists.com/who-are-we/) uses is adding vitamins and mineral is like adding a wheel to a car. If you onyl have 3, then adding the 4th is really going to make a massive difference. If you already have enough however, it's like adding a 5th wheel, which will essentially do nothing, and could be harmful.

It works well as an explanation, as people do seem to try and reduce complex functions to simple rules, and extrapolate from specific populatiosn to create general rules (not helped by studies that are minimally generalisable)

A 50,000 IU pill is smaller than a pinto bean. I'm not saying to not take vitamin D, but it can be overdosed with serious negative side effects and the best way to not do that is to consult your physician.

Where did you find 50k pills? I'd like to get some... Most I find anywhere are 5k, and I'm the only one I know that buys them. In a supremajority of cases 50k daily would mean... let's see... about 10 fistfulls of pills. It takes dedication to swallow that much every day.

50k is a one time thing, you shouldn't take this everyday! Read other comments there are articles about the toxicity of 60k per day leading to kidney failures.

I would never take more than 10k daily, and even that might be too much. I really need to have my blood tested.

Here in France when doctors prescribe vitamin D it's a one time thing, say for 3 months. It's in liquid form and comes in a small glass tube.

It's either 50 or 100k.

From "The Big Vitamin D Mistake" by Dimitrios T. Papadimitriou ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/ ) > This could lead to a recommendation of 1000 IU for children 1 year of age, and around 8000 IU for young adults and thereafter. Actions are urgently needed to protect the global population from vitamin D deficiency. Then, a person that consumed from 8000 IU to 12000 IU per day and had kidney damag…

What about D3K2 supplementation (adding in K2 supplementation) to counter these high levels of calcium?

You can get an extensive screening for around 120 here in Amsterdam. Probably more expensive if I go through official doctor and have to pay it with eigen risico (first few 100 euros of healthcare you pay yourself).

You know I use a vitamin d supplement because I'm not a big outdoors guy and I livein the northern USA and I was deficient at my last annual inspection. That said why does HN seem to have a vitamin D story everyday? It's not a magic pill. If you have deficient levels you should do something about it, but it's not a cure all.

Lately it does effectively sounds like a magic pill.

It's hacking the body!

At least the Soylent thing more or less died off. In a way it's comforting to know that the übermenschen on HN are as fad-prone as anyone.

It died off because it's more commonplace now. Lots of people are taking meal replacements.

It's worth noting that vitamin D has a lot of high-confidence but low-effect results going for it, including a lot of strong meta-analysis over many health outcomes. What I mean by this is that it usually seems to conclusively either do something beneficial, but minor, almost nothing in the case of many studies, and in the case of some others, something very beneficial (as we've seen a few of in relation to covid rec…

I've looked up your list and remembered great movie Vitamania. Most striking part was that to people living in space, no suplements are provided except vitamin D. Every other is gained from various food they eat. And the supplement industry is barely regulated and HUUUGE in US.
