The All-Encompassing Vitamin D Thread

Well, she is smaller than me, but going on the 1000iu per 25lbs BW, she should be at around 5000iu. Dosing in relation to 25(OH)D levels is a very individualistic. Men, for whatever reason, generally require more. Dr. Davis has some input on this here:

Vitamin D dose needs to be individualized. Factors that influence vitamin D need include body size and percent body fat (both of which increase need substantially); sex (males require, on average, 1000 units per day more than females); age (older need more); skin color (darker-skinned races require more, fairer-skinned races less); and other factors that remain ill-defined.

But these are “rules” often broken. My office experience with vitamin D now numbers nearly 1000 patients. The average female dose is 4000-5000 units per day, average male dose 6000 units per day to achieve a blood level of 60-70 ng/ml, though there are frequent exceptions. I’ve had 98 lb women who require 12,000 units, 300 lb men who require 1000 units, 21-year olds who require 10,000 units. (Of course, this is a Wisconsin experience. However, regional differences in dosing needs diminish as we age, since less and less vitamin D activation occurs.)

Let me reiterate: Steroid hormone-vitamin D dose needs to be individualized.

There’s only one way to individualize your need for vitamin D and thereby determine your dose: Measure a blood level.

Nobody can gauge your vitamin D need by looking at you, by your skin color, size, or other simple measurement like weight or body fat. A vitamin D blood level needs to be measured specifically─period.

I'd actually like to get her into the 60-70ng/mL range, but she's already bitching about taking a "handful" of pills a day.

Thanks.

LOL @ 'handful' of pills.

Every morning I put 1 multi, 1 fish oil cap, and 1 vitamin d cap on the table for my wife to take and she bitches every single time.

Anyone know at what levels of supplementation calcium being deposited in the arteries and organs could become a concern if is even more than scientific speculation?

Nothing new there, but right when I saw the headline I knew it would be about Vitamin D. This stuff is like the new fish oil or something. Everytime I open the newspaper or go online it seems there's something pushing it.

Any of you guys experiment with the Stoss method of dosing? Basically one mega-dose per week?

Since the half-life of D3 is between 30-60 days, technically you could mega-dose at farther intervals; the rise and fall of one's 25(OH)D levels would be more acute, versus smaller daily dosing, though.

I think that problem I discussed with you is actually a mild chest cold or something. After I workout it seems to worsen. I called my doctor but he's pretty much booked up solid for a while and the walk in clinics are insane.

New post by Dr Davis on optimal 25(OH)D levels:

So do we really know the truly ideal level of vitamin D to achieve? I believe that, given the above observations, it is reasonable to extrapolate that the ideal vitamin D blood level likely lies somewhere above 50 ng/ml. We also know that vitamin D toxicity (i.e., hypercalcemia) is virtually unheard of until vitamin D blood levels approach 150 ng/ml, and even then is inconsistent. The health benefits of vitamin D supplementation are so tremendous, that I am not willing to wait for the prospective data to explore this question fully. For now, I aim for a blood level of vitamin D of 60-70 ng/ml (150-175 nmol/L).

So without blood analysis one can not be sure about how much they should take vitamin D?
1000 IU of vitamin D is 25 ug.

I get about 5 ug from milk daily. I just bought some 10 ug D-vitamin pills. So if I take 2 of those every day I get the 1000 IU. That may be a bit low?
