The All-Encompassing Vitamin D Thread

As I said earlier in this thread, I use Nature Made 1000 I.U. gel caps, which you can find just about anywhere.
 
gel cap. To be fair, I can't say with 100% certainty that the liquid inside is oil, but I think it is.

And it definitely is not powder.
 
Ingredients list corn and soybean oil on the Nature Made liquids. I was looking at them since I bought their fish oil for over a year until I started getting it from True Protein.

I'm contemplating switching from their tabs to the liquids because of the corn and soy oil. I know even at 4 a day that that would be very little corn and soybean oil, but I'm still hesitant.

Dude, it would be a small fraction of a gram, and we're talking about substances that only harmful when consumed in very large amounts, and even then, the "harm" is not exactly poisoning. I mean the tabs have maltodextrin and corn starch, neither of which are particularly healthful, but neither of which will hurt you in small amounts either.

The nature of supplementation is that in order to encapsulate, powder, or liquefy a nutrient, it will have to undergo some kind of less-than-natural process (which distinguishes "supplements" from whole food). However, we consider the benefits of that supplement to be greater than the consequences of that processing.

If your concerned about that, look into liquid vitamin D. I inadvertently found it while on the hunt for gelcaps. For whatever reason, I haven't found a health food store that carries the gelcaps, but I did come across this:

Ddrops: product line

Which was actually recommended by the N.D. I saw a while back. One of the few useful things she recommended.

Nature Made is usually carried in drugstores and grocery stores. Try those. I haven't really looked hard, but I don't think my local GNCs carry Vit. D gelcaps either.
 
I wouldn't think there'd be much difference between taking the gel caps (vit D with fat) and taking the tablets with a meal containing fat (which even a low fat meal should have a hell of a lot more fat than the oil found in the gel caps).

Just my opinion though.

No, that makes good sense, but I think the issue lies with how well the tablet is broken down, and the bioavailability of the dry form cholecalciferol. Dr. Davis has mentioned that in 80% of the patients he's had being treated with vitamin D tablets have had a zero rise in their 25(OH)D. With gelcaps? All have had a rise.

That very well could be the case.
 
The way I see it, the gel caps are effective, cheap, and readily available, so why not err on the safe side?

I don't know, man. I just dug this up...

A randomised comparison of increase in serum 25-hydroxyvitamin D concentration after 4 weeks of daily oral intake of 10 microg cholecalciferol from multivitamin tablets or fish oil capsules in healthy young adults.

Many types of vitamin supplements are available on the market, but little is known about whether cholecalciferol obtained from fat-containing capsules differs in bioavailability from that of solid tablets. Our objective was to test whether 4 weeks of daily supplementation with 10 mug cholecalciferol given as a fish oil capsule produces a larger increase in serum 25-hydroxyvitamin D (s-25(OH)D) concentration compared with the same dose of cholecalciferol given as a multivitamin tablet. A total of seventy-four healthy subjects aged 19-49 years were initially included and fifty-five of these completed the study and fulfilled the inclusion criteria. After completing a self-administered questionnaire about diet and sunshine exposure and having a non-fasting venous blood sample drawn, participants were randomised to receive daily multivitamin tablets (n 28) or fish oil capsules (n 27), each containing equal doses of cholecalciferol. A second blood sample was drawn after 28 d. Mean baseline s-25(OH)D was 40.3 (sd 22.0) nmol/l in the multivitamin group and 48.5 (24.8) nmol/l in the fish oil group. When controlling for baseline s-25(OH)D, mean 4-week increase in s-25(OH)D was 35.8 (95 % CI 30.9, 40.8) nmol/l in the multivitamin group and 32.3 (95 % CI 27.3, 37.4) nmol/l in the fish oil group; the mean difference was 3.5 (95 % CI - 3.6, 10.6) nmol/l (P = 0.33). The results were unaltered by statistical adjustment for BMI, ethnic background, age and sex. We conclude that fish oil capsules and multivitamin tablets containing 10 microg cholecalciferol administered over a 4-week period produced a similar mean increase in s-25(OH)D concentration

I'm not saying that this is the end all of proof. Dr. Davis could certainly be right. But is he right because a lot of people take tablets without food? Just being a bit skeptical. It's my nature :D

Just throwing it out there, that study used 400 I.U. of D. The doctors that have been quoted in this thread, as well as the ones I have seen on other blogs, are recommending regimens of at least 2000 I.U., because they don't see the blood level measurements they're looking for at anything less.

Not sure what this means, but they don't seem to be on the same page.
 
I posted that for the hell of it. I was curious and did some quick searching. No big deal, really. You're right in the fact that if gel caps are comparable in costs, there's really no reason not to use them.

There are also some lesser forms of Vit D found in pills as well. This might also be part of the whole thing. Maybe a lot of the tablets that Dr. Davis clients were choosing weren
