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…

The Dutch health care system is allergic to preventative care. It's stunningly hard to try and just get routine things checker/done. As an Australian, having lived in four different countries, I'd say the Dutch system is the odd one out here.

If you are taking vitamin D supplementation, your physician will surely prescribe you periodic testing, at the very least if you ask for it. But since I have a private testing point just beside my office, I go there without doctor prescription; last time it cost me 17€ to get my vitamin D checked. This is in Italy.

In Germany you have to pay (35-40 EUR) for your blood test to check for deficiency even if you were previously found deficient and must re-check after supplementing. My doctor also doesn't give a fuck and never asked me to re-test.

In Hungary you can get it done anytime for like 10 euros.

More complex screenings can cost between 30-100 euros.

Or get it all for free if your doctor prescribes it. It is quite easy, you just have to be a bit lucky to have a doctor who actually want to go trough the investigation about your health issues.

This study was done in China. It is important to know the locals behaviour with regards to natural Vitamin D source (the Sun). Locals do not like to have "too dark skin" and as such are using sun screen with factor 50 and try avoid sunshine altogether.

This study might have different results in other parts of the world.

> Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day. Well of course, drinking 100x times the recommended amount of water would be even worse.

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.

In Spain you go to your healthcare doctor and ask, and they will usually grant you the blood test, but it depends on them. I never had any issues though.

I think 200-400 euros once per year (hell it doesn't even need to be that often if you're young) should be acceptable on NL standard of living, here in Croatia if you get a private life insurance plan (around the same amount/year) they include some yearly tests + general checkup and cover up to 200 EUR tests in partner clinics.

I'll add that even many non-dairy milks are fortified with Vitamin D - check the label.

The way I understand it is that drinks fortified with Vit D are nearly always fortified with D2, whereas the consensus seems to be that D3 is the way to go. Not sure whether that's because D3 is less stable in drinks, or maybe there's another reason to prefer D2 there?

According to this article D3 is never vegan: https://www.healthline.com/nutrition/vitamin-d2-vs-d3#TOC_TI...

I believe “being vegan” is the point of most milk substitutes.

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…

> exciting supplement I've never taken one in my life and have excellent vitamin D levels. Most people call it going outside you desk jockey nerds.

Not everybody lives at the latitude their skin has evolved for.

Same in Germany. Even when paying privately (despite being in the common healthcare), I've had problems getting an appointment.

It's sad, because a full blood profile (including hormones) has such huge cost to benefit ratio in avoiding completely unnecessary speculative wild goose chases.
