Weeeellll :) Toronto Harborfront Center is at 43.6397877,-79.3836877,17.12z according to Google. If I look for the southern most part of Germany, that seems to be Oberstdorf which is at 47.3997083,10.2805651,14.08z ;) Or in other words, Germany in terms of natural sun light exposure in winter is way worse than Toronto. In fact, in Germany its dark much earlier and sun comes up much later for longer. I hear cloud cove…

Wow, TIL. That’s kind of nuts, I just looked at latitude lines because I was sure you had to be wrong but it looks like where I live (which is actually Hamilton) is the same latitude as northern Italy. In fact, it’s almost exactly the same as Florence, where the forecasted highs over the next week are in mid- to high-teens (C). We have a blizzard and most days next week the high is 1 degree. I honestly didn’t realize…

Wind and ocean currents make Western europe way warmer than Canada for a given latitude. Ottawa is only about 45 degrees north, same as Paris. Most of England is further North than that.

I’ll try to get 15-30 min of sun exposure without sun screen in the warmer months each day. Feel immensely better during then, to a point where I’ve seriously considered moving somewhere warmer without real winter months.

Is UV the sole reason for the generation of Vitamin D?

Vitamin D is found in fish, and milk usually has added vitamin D (so you can use the calcium). If you eat 20 eggs you can get 100% of your daily value of vitamin D from that, but I don't recommend it.

Besides dietary sources you need UVB to make vitamin D: https://en.wikipedia.org/wiki/Cholecalciferol

You're welcome.

Also: Look up New York City ;)

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?

It is important to co-administer Vitamin K-12 with the D due to its effects on calcium.

K-12? Do you mean K2?

Natural Vitamin D level is a marker of sun exposition, not the effective part of the sun.

Infrared is the important part, it is necessary for our system to control inflammation in mitochondria.

Already ton of research on this, but still completely neglected.

Id suggest you get a couple vitamin d tests in different seasons and also consider your latitude. i was taking about 4000iu + natural sources in the winter and i still tested low and had to increase my intake. If you dont test you're sorta just guessing.

take with meal or fats.

cramps could also be from low potassium.

my natural sources i use are - whole fat yogurt - pastured eggs (way higher in vit. d than grain fed) - kippers/hering fish in can (no oils)

oh and like someone else said. i do this too. i take my vit d and k2 mk7 at the same time - with a meal or fatty food always.

You can get your APOE ε4 status, which is a marker for Alzheimer's and dementia, from any DNA test like 23AndMe. To protect your privacy: use a fake name, new email address, and get a temporary UPS Store mailbox address for the kit to be mailed to. Use a Visa gift card for payment. Yes, it can be done and it works.

>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.

You can never have DNA privacy because you leave it behind wherever you go. It's also probably not worth anything.

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: https://www.smithsonianmag.com/smart-news/you-could-be-ident... ...the odds of being positively identified by your DNA is or soon will be almost certain.

You’re missing a key part of that article:

> a good sleuth could construct a family tree and then conduct more targeted research that might lead to someone who had never submitted his or her DNA for testing, as was the case with the Golden State Killer

So this assumes the sleuth does “targeted research”. That’s only going to happen in things like criminal cases or other cases of big interest. It’s not going to happen to someone like me, an average Joe who has no one looking for him but is looking to protect his privacy by attaching a fake name and address to a DNA sequence.

I dove deep into Vitamin D supplementation research during Covid. The tl;dr as I understand it - and bear in mind I'm a layperson in this - is that while Vitamin D deficiency correlates to many bad things, taking Vitamin D doesn't help . It does raise your level as it shows up in blood tests, but the bad things still happen. Except for some very specific issues. I have a mild deficiency and used to take Vitamin D. I…

The reason is because vit-D is a marker of sun exposition but the the important part.

Infrared is: https://youtu.be/wadKIiGsDTw

TLDR: get some real sun, if you can’t infrared light.
