Sure, but the winter climates in many geographical regions don’t provide adequate sunlight during winter.

I was pretty amazed to Discover that Spirit Airlines is doing round trip flights for $75 to Orlando from my local airport. If you’re in the Midwest in a midsized city that’s cold and dreary in winter there’s a good chance you can find a similar deal.

Congratulations, you have proposed the least ecologically sustainable vitamin boost I've ever heard. Every day brings new surprises.

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…

Roughly the same in the UK, at least in my experience. In Romania, getting blood work is very common, even for trivial things. A few years back it was also very cheap, about 20-30 euros for the basics.

To be fair, that's not cheap for Romania. Most people can afford it, yes, but that doesn't mean it's cheap.

Or just get some sunshine! It's likely there are other benefits, besides just the vitamin D.

> Or just get some sunshine! Where I live I haven't been able to get sun actually on my skin for the last three weeks. I saw sunshine through the window one day last week while in a meeting, but it was gone an hour later. According to my weather app the next break in cloud is more than a week from now. Even when there is sunshine in the winter, it's often too cold to expose more than a tiny amount of skin anyway. Ple…

>Please don't assume we all live in California.

Same here, although at least there's sun on weekends for me (if it isn't cloudy). Looking out the window, and being outside on the weekend with a winter hat and long sleeves is probably not allowing a lot of vitamin D.

I'm wondering if there's something like a good lamp that gives UV light without being too strong.

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 the US, I was prescribed weekly 50kIU pills. They were the same size as my current 2k doses.

I think it looked something like this [0]. Curiously it was much cheaper than my supplements after insurance and was like $0 or $5.

Am I the only one who finds it laughable to consider trusting the word of companies the likes of Delta, Southwest, and US Air? They seem fundamentally incompetent in pretty much every other aspect of anything that doesn't involve literally keeping the plane from crashing. Why would I believe the air filtration systems are even going to be operational, say nothing about effective when they are?

Pressurized airliners have about 15 air changes per hour or 3-4x what’s typical in an office building. This is air exchanges with the outside, not filtration cycles which are in addition. Even if the filters were entirely INOP, I suspect you’re no worse off than sitting in an office building. Now, I’m not doing that right now, but there’s little reason to think major US carriers aren’t doing what they say they’re doi…

Sitting in an office building is one of the worst places you can be for avoiding getting sick.

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…

Also look at Liebig's barrel (https://en.wikipedia.org/wiki/Liebig%27s_law_of_the_minimum#.... It was originally applied to plant growth, but it is a helpful metaphor for vitamin substitution.

I had been taking D for almost a year every day. (4000 dose) and wasn't feeling well at all. Once I stopped D and take it occassionaly I feel much better.

Did you take a soft-gel or hard tablet?

Soft-gel

Funny -- I was just digesting a competing study released recently[0] which showed little-to-no benefit from vitamin D, Omega 3 fatty acids, and exercise (either alone or in combinations). That study used 5X the daily vitamin D as this one. So I guess the jury's still out and I may choose to continue to err on the side of supplementing vitamin D.

No. I'm a computer scientist and work at the computer. In my free time i play at the computer. I don't like to walk around for kilometers in my free time.

Just because some people want to do it / can do it, it is not the same for everyone.
