> if you are in a office job you are def. not getting enough vitamin D. I think this really depends on location and lifestyle. Anyone in a Mediterranean or sunnier climate that spends more than 30mn a day outside will be fine

I spend lots of time outside and I live in California. I still had life-long vit D deficiency, probably since birth. No idea why, might be something genetic. The only way I could figure it out was via blood tests, spaced a few years apart. First time the doctor said "hm, you're pretty low on vit D, you should supplement it". Second time, it was more like "you're really low and you should take XXX amount each day, NOW…

Sometimes deficiencies in other parts of your diet can reduce Vitamin D uptake, i remember reading somewhere. something to consider

A psychiatrist I saw multiple years ago told me to start taking Vitamin D. I went more or less blindly with 5,000 IU after reading some internet articles. I got my blood checked last year and decided I should probably actually know if I'm doing too much or too little. I was within 5% of the middle of the healthy range for vitamin D levels. For reference, 5,000 IU is >800% the FDA daily recommended value. People with…

To be fair: It isn't just folks with indoor jobs and hobbies. I've discussed this with my doctor after being severely low on vitamin D. It caused physical pain. I'm far enough north that it is impossible to get the sunlight needed during the winter. I still have days, but they are short without strong sun - not to mention that it is too cold to go without a jacket. So, supplements at least during the winter. During t…

My doctor told me (as he was telling me I needed to take vitamin D) that really at most latitudes in the US (including SF), the sun light is too weak and you won’t get enough vitamin D from sun exposure. This was all to tell me that I should still take an oral vitamin regardless of how much time I was able to spend outside.

Anecdote, so take it for what you will.

Interesting thing... Vitamin D is one of those things that, when vitamins come up on HN, you will often hear the refrain that "it's the one vitamin that large numbers of people are actually deficient in and ought to supplement." I've heard that many times over the years and I have taken a Vitamin D supplement on and off (more off than on) over the years. When this COVID-19 thing first hit, I had a physical scheduled…

Given the fact that vitamin D deficiency is really prevalent across the entire population, I’m not sure how much weight to give to this study...

Sunlight exposure is also bad for you; taking it orally is the way to go for most people. As pointed out upthread, most supplements are hilariously low-dose. I take 20k IU, 3 times per week. (most supplements are like 1000IU per pill, but 3000IU pills can be found)

Isn’t some sunlight exposure good in general? I think it’s going too far to declare sunlight as genealogy dangerous. It definitely helps me with my mood.

my understanding standing is that the older you get the less that your body can metabolize from sunlight and it’s sunlight that occurs for a small period of time during the day based on the angle of the sun and the type of UV rays that are filtered. and you need to be naked

Nobody makes any money if it turns out to be a good treatment, so nobody will fund the research

This is actually very true. There are lots of potential treatments that use generic and non-patentable agents, and very few people are willing to look into it. Zinc is the classic example; some people think it maybe reduces the duration of the common cold. The common cold is one of the main causes of missed workdays. If there's a drug that could make you miss 4 days of work a year instead of 5 days of work a year, it…

Zinc's neurotoxic, which is why it permanently damages your sense of smell and also why people are hesitant to take it to cure the common cold.

I've been sick for almost ten years and had low vitamin D levels. Last two years I've finally found some treatments that work for me, now that I'm healthier my vitamin D level has gone up to about 40 even though I rarely go outside and don't supplement. It's typically 5 without supplementation.

Previously, I tried supplementing with 10,000IU daily, didn't help me feel any better and took a long time to get my levels up. Doctor even told me to lie outside in a bikini every day in the sun and not to burn myself. My doc's theory is that some process in sick people uses up their vitamin D and calcium, and that's what needs to be stopped. He says he has seen patients with Vitamin D deficiency where they are cured with supplementation and/or sun, but it's not very common. It's cheap, easy, and harmless enough though to try before moving on to other things.

Also, the absorption of it orally appears to be kind of finicky.

Some things like vitamin K and magneseum help absorbtion.

Vitamin K (specifically K2) is personally on my short list of vitamins that I think Americans are short on.

i loaded up on a bottle of costco vitamins and d3 supplement before we went on lockdown. There seems to be something in the multivitamins that i'm allergic to in high quantities, i.e. after taking them for 3-4 days straight I'll start getting hives. I reduced consumption to 1 mv tablet every 3 days and no problems so far. I'll probably increase d3 intake to 1 2000iu tablet per day and see how it goes.

Weird that it took a few days for the allergy to kick in. Do you get hives from other stuff?

I had a bad allergic reaction recently to wine (which was never a problem before), that started as bad hives and progressed to me nearly fainting. Doctor tested me as positive for a grape allergy, but negative to the shellfish allergy that caused hives as a kid.

Anyhow, all of that is to say that the doctor prescribed me an epipen, because apparently it's possible to experience anaphalaxis without having breathing issues. And full-body hives is one sign of that. The near-fainting I experienced was likely due to low-blood pressure, which is another symptom. So just be careful. I had always thought hives weren't a big deal (other than being extremely annoying), but I'm definitely going to take them more seriously from here on out.

I also had a vitamin D deficiency that was found after a particularly bad string of colds, my Dr told me to take a supplement(5000ius daily) of vitamin D and have not seen anything like it since. Apparently windows cars/office block sunlight's ability to create vitamin D in a person so a car ride or sitting near an office window does not provide any help. And if you are in a office job you are def. not getting enough…

You need UV rays which are blocked by most windows.
