The Big Vitamin D Mistake (not enough)

There's been signs of this for many years. I've been taking 4000-8000 UI daily for over a decade now (in gelcaps -- vitamin D is fat-soluble, so the dry tablets aren't as well absorbed). I recommend you also look into Vitamin D supplementation, especially if you don't live in tropical areas where you get plenty of sun year-round.

One guy who's been writing about this for a long time is a cardiologist named William Davis, I remember reading some of his stuff maybe 6-7 years ago.

I too have been taking D3 in about the amounts you have for almost 10 years.  I take 10K UI 5-7 times per week.  I always take it on work days where I spend the whole day in the office.  I always take it everyday in the winter (not much sun in NH) and I'll take it or not on the weekends in the summer depending on what I am doing. If I'm going to be outside all day in August I'll skip it that day.

Also I look for the gell caps packed in olive oil or coconut oil rather than high omega-6 oils.

These are the two brands I've been using:

I've also read somewhere that Vitamin K2 helps with the absorption of D3 (and vice versa) so I take K2 with it as well:

With all due respect,

"been writing about this for a long time"
What do you mean by "this"?
?Skeletal health or extra-skeletal outcomes, including cancer, cardiovascular disease, diabetes (type 1 or 2), and autoimmune disorders?

Do you base your "recommendation" on a review of the literature and do you account for appraisal of info using evidence-based guidelines?

The questions are meant to be constructive.

All of the above, looking at the varying amounts of evidence for each that there are benefits to supplementing, especially in northern countries like Canada, where I live. You can go read his stuff, I'm sure there's an archive on his site.

For some weird reason I haven't been able to find 5000 UI per unit in Canada for the past couple years. It's almost as if some weird regulation made it so that the max concentration in the country is now 1000 UI. Very annoying to have to take so many small gelcaps... I hope this madness will soon end.

Don't want to make a big deal out of this.
But, in a parallel to investing, delineating facts from beliefs has value.

Let's say:
-The Lancet has published an article saying that vaccines cause autism.
-On a widely followed Twitter feed, this "finding" is confirmed.

So, vaccines should be banned?

Respectfully submitted, there exist guidelines now (that may eventually change with new confirmed evidence) that are helpful if one wonders about the indications related to vitamin D supplementation.

Feeling grumpy today.  I should take my own advice sometimes.

Liberty,

you take multivitamins?

Liberty,

I don't. Daily I take Omega 3, vitamin C, and Vitamin D, and K2 (MK-7).

I've been updating my bayesian priors on this for 15 years, this isn't just one article. I wanted to share it, though.

Make up your own mind, but please don't project things on me without knowing how much research I've done.

Vaccines don't cause autism, not because of one article, but because of a ton of evidence in one direction and little to none in the other.

Just from first principle, it's pretty easy to see how most of the world's population could be deficient in Vitamin D based on the conditions in which our bodies have evolved.
