Could you share your thoughts on the benefits of high doseage supplementation of this vitamin? I began taking it several months ago for general health. Funny thing is, it seems to have a dramatic positive impact on my prostate health. This is a benefit I have read nothing about from any source. Great, but puzzling. Note that I have changed nothing else in my daily supplement regimen. Thanks, in advance for any thoughts you can share.....

Vitamin D reduces the PSA level in prostates which will reduce swelling.
Its also useful in treating prostate cancer. Make sure you take the D3 and not the D2 which is less effective.

For other health benefits of Vitamin D press "search" and type in 'vitamin d'

Thanks liverock. Yes, I am using the D3 version. Wish I would have known about this benefit years ago...By the way, I recently had my lowest PSA results in years so your info seems to be right on.....

There are tons of posts on Vitamin D3 on this forum. Do a forum search and you will find links to studies, and how people here have used it.

Vitamin D is an effective treatment for prostate cancer in some patients, a UK study suggests.

That's pretty phenomenal if you're lucky enough to be one of the 20%.

PSA is nothing more than an indicator of fungal mycotoxins, period.

If you want to lower your reading, go on the phase 1 diet for a month and take some natural antifungals.

Everyone should increase their D3 intake, to at least 4000 I.U. per day just for general good health, and that has nothing to do with prostate issues.

Where is Ted? Me and him already had a discussion about my libido. Had a massively positive effect and has not gone down I'm pleased to say.

I currently switched regimen for a wee while and now take my D3 dissolved in MCT, O3 and Ubiquinol.

Another positive benefit of D3 is that it is supposed to help one keep
from getting the Swine Flu. Of course if your already in the Senior Citizen
catagory, you probably don't have to worry about H!N!. LOL!

This study was done with Vitamin D2. I've always heard that D3 is better and that's what I always use. If I remember right D2 has a shorter half life...whatever that means.

Long-term high dose vitamin D well tolerated


A research letter published in the October 26, 2009 issue of the American Medical Association Journal Archives of Internal Medicine revealed that treatment with 50,000 international units (IU) of vitamin D per week was safe and effective over an 8 week period, and could also be safe to use every other week as maintenance.

In their introduction to the article, the authors, from Boston University School of Medicine, note that "The worldwide prevalence of vitamin D deficiency is striking, and more than 40 percent of the population may be vitamin D deficient. Despite this, to our knowledge, there are no long-term studies of the safety and efficacy of giving pharmacologic doses of vitamin D (50,000 IU of ergocalciferol) to treat and prevent vitamin D deficiency."

"To prevent recurrent vitamin D deficiency and also to maintain adequate levels in patients who are vitamin D sufficient, we treat with 50,000 IU ergocalciferol every other week indefinitely, a regimen that, to our knowledge, has not been published to date," they write.

The researchers, including well-known vitamin D authority Michael F. Holick, PhD, MD, reviewed medical records of 86 patients aged 18 to 91 who had received two or more blood tests for 25-hydroxyvitamin D levels and were treated for vitamin D deficiency or insufficiency. Pretreatment 25-hydroxyvitamin D levels of 92 percent of the patients were below 30 nanograms per milliliter (ng/mL). Forty-one subjects received 50,000 IU vitamin D2 (ergocalciferol) weekly for 8 weeks followed by a maintenance dose of 50,000 IU every other week for up to 6 years. The remainder of the patients received every other week maintenance therapy without the initial weekly treatment.

For the 41 patients who received the weekly 50,000 IU starting therapy, average 25-hydroxyvitamin D levels rose from 19 ng/mL to 37.2 ng/mL after 8 weeks. Maintenance therapy increased these levels to an average of 46.9 ng/mL. For the patients who received only maintenance therapy, 25-hydroxyvitamin D levels increased from an average of 26.9 ng/mL to 47 ng/mL. Serum calcium levels, which could be an area of concern when high amounts of vitamin D are ingested, did not change over the course of treatment. No kidney stones or other signs of vitamin D toxicity were observed.

"Vitamin D2 is effective in raising 25-hydroxyvitamin D levels when given in physiologic and pharmacologic doses and is a simple method to treat and prevent vitamin D deficiency," noted Dr Holick, who is a director of the General Clinical Research Unit and professor of medicine, physiology and biophysics at Boston University School of Medicine. "While treating and preventing vitamin D deficiency, these large doses of vitamin D2 do not lead to vitamin D toxicity," he concluded.

Nobody should take high doses of vitamin D without testing serum levels,especially if they are taking ongoing dosages. Guessing your vit D levels doesn't work as we all assimmilate at different levels due to genetic variations.

Grassrootshealth have a cheap pinprick test you can do at home and you get the result back in 2/3 weeks. I have no FI in this company.

While I agree that a 25(OH)D test is a good idea and the Grassrootshealth D Action link provided is the cheapest source such is the safety of vitamin D3 that it is reasonable to suggest people take an EFFECTIVE amount such as 5000iu/daily for around 3 months to see how they respond to that level before having a test.

The purpose of the test at this point is to see if 5000iu/D is sufficient to achieve a reasonable level.
We know that up to 10,000iu/daily is absolutely safe even in the presence of ample sunshine. We also know that given full body sun exposure human skin will create between 10,000~20,000iu of a bioidentical form of Vitamin D3.
It is therefore without doubt totally risk free to take 5000iu/daily BEFORE getting a 25(OH)D TEST.

When you get your test result you will then be better able to judge how much extra you will require if you level is still below 55ng/ml. 1000iu/daily is usually required to raise status 10ng/ml 25nmol/l though those with inflammatory conditions may require 2000iu/d to achieve the same improvement.

My point is that average UK status this time of year is probably around 20ng/ml 50nmol/l and dropping (end October) so it is safer to supplement at an effective rate ASP. In 3 months time, end of Jan ~ Feb the 25(OH)D test will show if 5000iu/d is sufficient.

If you wait for a test before supplementing that will not help you know how you respond to D3. It will only tell you that you are deficient and common sense should tell you that without wasting money on a test.

You know if you've been taking an effective amount of supplement or not for the last 3mths or not or have been using a sunbed. If you haven't then supplement first for 3mths then test.

50,000iu weekly D3 is equivalent to 7100iu/daily and is a reasonable way of attaining and maintaining status.
I don't really understand why Holick is pushing the D2 option.
$168 for 100 x 50,000iu DRISDOL or $30 for the safer, more reliable, more effective BIOTECH PHARMACAL D3 X 50,000IU.
What kind of ethically challenged moron recommends the more expensive less effective less reliable form?
Follow the money.
I presume someone is looking for funds for research funding and this is the quid pro quo.
