I’d like to supplement but every time I take one I get muscle cramps. I suppose it’s just pulling all the magnesium out of my body or something?
I tried magnesium supplements with it but it didn’t help.
Maybe 5000IU is just too much?
Vitamin D supplementation and incident dementia

Re: Vitamin D supplementation and incident dementia
#52Hey people who follow the science: As an “indoor human”, how much should I be taking? (TIA!)
Some might not like this answer but the best course of action is still some sun exposure. As for the actual answer, someone correct me if I'm wrong but there there are multiple 'variants' of vit. D and the vast majority of "vit D" supplements most likely don't include the complete formula (which is arguably the best way in order to also assimilate it "fully"). The daily recommended dose is fine unless you're deficien…
Older folks most at risk can't make it naturally. D3 is the best bet and complete.
Re: Vitamin D supplementation and incident dementia
#53Like all studies into Vitamin D supplementation that aren’t randomized controlled trials, it’s very hard to tell apart cause and effect. Vitamin D naturally occurs when people go outside and get exposed to the sun, and going outside is correlated with all sorts of healthy traits. Also, publicity of the association of vitamin D with good health has led people who care about their health or who have access to good medi…
I'd also mention this isn't the only study with this sort of problem. Any health study looking at things that push people out of the house have this problem. People that can leave their homes tend to be in better health than people that can't.

>To protect your privacy... You can't really expect too much privacy with a DNA type test, right? Since it knows all of your relatives who have also (or will ever) taken the test.
Even if they correlate your test results to your relatives, so what? If you’ve used a fake name and mailbox, they can’t know who you are. You’re just a set of AGCT encodings.
The paper this article discuss is already more than 4 years old:

...the odds of being positively identified by your DNA is or soon will be almost certain.

#55I've been taking 1000 IUs daily, for the last 20 years, skipping summers (during which I would attempt sun exposure), while continuously being within acceptable medians for my age. I sure hope what I am typing now makes sense :-)
Older folks can't make D naturally, so you may want to skip your summer skipping soon.
For all we know they are only 20 years old.

I had thought that it was possible to get vitamin D from moderate sun exposure in the winter and went looking for info to refute your post. Turns out you are right and I was wrong: https://www.nytimes.com/2022/12/06/well/live/vitamin-d-defic... People living above the 37th parallel, basically the tropics, may not be getting enough in the winter, because the sun isn't strong enough to provide it.
It’s brutal, I live near Toronto and not only is the winter sun quite weak but sunny days are quite uncommon. Almost every day is grey and overcast. Combine that with short daylight periods and winter becomes quite the gruelling challenge in terms of mental health especially.

From what I understand, vitamin D causes calcium to be released into the bloodstream which can cause cramps. Are you taking vitamin D with vitamin K (MK-7)? Taking MK-7 ensures calcium is deposited in your bones, not your arteries.

Yes, thank you for this. I would additional repeat myself to say a very simple thing. If you have to wear clothes over your skin, because it is cold, no sun at all helps you out. I do not go out in a t-shirt when it is snowing..
BTW Inuit getting there vitamin D from fatty fish and other animals, not from the sun.

I take mk7 with it too. But perhaps it’s a lack of calcium that’s the issue.

I think the influence on this study is probably inverted though as supplementation could be based on a recommendation to compensate for lack of outdoor time as opposed to a study that measured levels.
