Health Summary

Gail Cashin Have you been tested? I take 5000iu in winter only as never see much daylight. It depends on where you are in the world.

Brandon VanDynhoven Wisconsin. And I work third shift

Sam Swinea The sun should be coming up when you get off. Get 20-30 mins out there

Brandon VanDynhoven Then I wake up and don't wanna sleep lol. I'm not against the sun I'm just stuck on third and it blows lol

Gail Cashin Yes you will probably need it then. Also try blue blocking glasses they help with shift workers and sleep.

Gail Cashin Take it when you wake up not before sleep.

Richard Harris Sam Swinea The ideal time of day for getting Vit-D via the sun is 10am-2pm and your latitude may make the time window narrower as well as time of the year.

Richard Harris I take 10,000 IU Vit-D3 daily, and last tested mine was 73.1 ng/ml
I work in IT so I'm inside most of the day.

18 hrsEdited

Brandon VanDynhoven I don't know what that means (73.1ng/ml)

Reply18 hrsEdited

Richard Harris The blood test for Vit-D level is "Vit D 25-Hydroxy"
Per Life Extension the ideal is between 30 and 100 ng/mL

Brandon VanDynhoven Nice, I really need to have some kind of check up or blood work done

John Kemp Don't take supplements unless you know you need it (I take vit D 2000iu a day, but my levels were measured at 19 ng/mL == low)

Brandon VanDynhoven Richard Harris any reason you did this over going to a doctor? I mean obviously diets like these are generally shunned upon but any other reasons?

Richard Harris Brandon VanDynhoven Just that since I don't get sick hardly ever I don't have a regular doctor, thus I don't feel like trying to find a good one just for some test I want. I used my HSA so not a big deal.

Charles Brewster Jr. Make sure you take Vitamin K2 with it.

Richard Harris Ideally take the K2 at a different time of day, IIRC A, D and K2 will compete for receptors.

Amy Van Oostende Yikes. I don't recommend that anyone take supplemental vitamin D.

Joanne Hope Oh really Amy? Do tell us how we're supposed to get optimal Vit D levels then?

Gail Cashin Does it not depend on where you live? It's dark in North Europe at 4pm, we are told to take it.

Joanne Hope Yes it does, Gail Cashin. Apparently Amy is in need of a geography lesson among other things. Lol

Amy Van Oostende Thanks, Joanne Hope. I have dug very deep into this research and feel quite comfortable not recommending it. It's not so cut and dried as you are assuming. I'll bow out of this conversation now as I'm not interested in nastiness. Good luck to you.

Joanne Hope Yeah. Lol

Fredrik Inngjerdingen Forså In parts of the northern hemisphere, you will get little to no vitamin D from the sun during most of winter. Supplementation is the best way to maintain healthy levels.

Sure, if you have access to the sun all year, that's great - you probably don't need to supplement. In Norway not supplementing during winter will cause your levels to drop, and you can't really balance it out from a diet that doesn't have supplementation in it.

Ann Margaret How did the arctic peoples get their Vit D when it was dark for many months of the year and even when it was summer they never took their clothes off very much because it was freezing?

14 hrsEdited

Emily Christiansen Shufeldt No need to be so rude to Amy Van Oostende. She was expressing her opinion. There are other ways to get vit D besides the sun; pastured lard, fish eggs, just some examples. Some how my family survived in northern Norway without needing supplements.

Richard Harris Ann Margaret Polar bear liver, but it also has lethal levels of Vit-A, so gotta be careful.

13 hrs

Ann Margaret Richard Harris Don't remember Stefansson mentioning much about the Inuit eating many polar bears in his books? The point here is that its been proven over and over that sufficient Vit D can come from the diet and the need for sunshine is exaggerated otherwise northern peoples would have died out a long time ago.

Fredrik Inngjerdingen Forså "CONCLUSIONS:
Our preliminary findings indicate it is possible that magnesium intake alone or its interaction with vitamin D intake may contribute to vitamin D status. The associations between serum 25(OH)D and risk of mortality may be modified by the intake level of magnesium. Future studies, including cohort studies and clinical trials, are necessary to confirm the findings."

Nothing here really says that supplementing with vitamin D is a bad thing? This is mostly related to high doses of magnesium, which is another thing entirely.

Amy Van Oostende You really need to read all of the stuff I posted to get the bigger picture.

Fredrik Inngjerdingen Forså My bad, only saw the first link, which facebook advertised.

Amy Van Oostende The Chris Masterjohn link was extensive. You must be a fast reader!
In any case I just posted a few resources. There's plenty more but I have a feeling we will have to agree to disagree on this.

Fredrik Inngjerdingen Forså Amy Van Oostende Not as fast as you, though "with the exception of your third link, which is just a wall of text, in serious need of a tldr, and references."

Fredrik Inngjerdingen Forså Amy Van Oostende And it would seem like it. How a nutritionist can blatantly say that all vitamin D supplementation is wrong, is beyond me. Especially considering the global aspects of this group.

Stephanie Sullivan Tackett When I tested very low, that's the dose my doctor put me on for about 6 weeks then had me taper down.

Fredrik Inngjerdingen Forså If your levels are low ( lower than 100), 10k iu a day will get rid of the deficit, and then you can maintain with 10k every second or third day, after a couple of weeks, or so. Get tested regularly, and stop when you reach a satisfying level (100-150nmol).

I was down to 30nmol, took ~45k a day for a week, and boom, up to ~150. Helped get rid of some fatigue symptoms. Also, supplement with k2 for improved efficiency.

Richard Harris Be sure to include the unit of measure, the test I had done reported in ng/mL (not mol) so some unit conversion might be needed.

Viktors Leonovs I am a tad undecided on that as well, but I think around a 100ng/ml up to 150 oughta be okay. Gotta refresh my knowledge though

Sebastien Fortier You got your unity wrong here,100 ng/mL is quite high..100 nmol/L to 150 nmol/L make more sense.

Gregg Sheehan As far as toxicity goes, there has been no study to show that 10,000IU daily has any toxicity in humans and only one poorly conducted study showing that 20,000IU daily caused mild serum calcium elevation (but not toxicity).

Viktors Leonovs I have taken up to 20'000 I.U. per day for almost a month, doc said nothing of my cholecalciferol status after recent blood tests, so I am probably still not in the OD range.

It matters how much you have stored, not just how much you ingest, mate.

Gail Cashin I like post like this, but we need to say where we are in the world, instead of saying the amount we are using. Someone in Singapore or Florida will not need the same as North Europe or Canada. Plus I like seeing how far PC is worldwide.

So I will say London UK 5000iu, winter only.
