Guest guest Posted November 11, 2005 Report Share Posted November 11, 2005 The half-hour web cast by Dr. Reinhold Vieth is very informative. This should be of special interest to Rodney and Al Pater who live in Canada and have suffered fractures or have bone problems. The statistical evidence for the cancer-prevention aspects of Vitamin D also seem significant. Dr. Vieth's recommendation is to take 1000 IU of Vitamin D per day which is in agreement with BT120YD p. 165.

Guest guest Posted November 12, 2005 Report Share Posted November 12, 2005 Thanks very much for that article, Jeff. Very informative and concise. I still wonder about the hypervitamin thing. Why is that not prevalent in the south if the limit is 2000 IU? I see guys working in bright sun more than 4 hrs per day without shirts. Of course they are well tanned. There must be a limit to what we can absorb, as in get into the blood stream. I do know from experience in hypocalcemia is not easy to regulate Ca+ using calcitriol drug. You ingest a little and check the CA+ repeatedly, until you find the right level. So calcitriol made by the normal body must be tightly controlled, ie, large changes in vit d supplementation or sun do not drive the Ca+ immediately upward. If we use serum Ca+ as a guideline to vitamin d supplementation, a level near the upper limit would dictate less d, and less sun. If our Ca+ is already near the upper limit, I would question using a lot of vit d, but OTOH, I know calcitriol must be regulated. So that brings me back to the question, how much vit d do I want to use for "optimum" health assuming I monitor Ca+, etc, regularly. I'm gonna GUESS I would want to raise it slowly between Ca+ labs.

However, I live in New England, USA, i.e., a northern clime. Given this and my job, where I am indoors all day, I figure my natural sunlight exposure is minimal.

I'm some- what confused by my numbers and the recommendations from recent papers. Is 1500-2000 mg/day calcium from dairy too much? Is 600 IU of D (from dairy and vitamins) too much?

Guest guest Posted November 15, 2005 Report Share Posted November 15, 2005 Hi Zen: There ARE problems with too much calcium intake. One is kidney stones, another is calcification of the arteries. It seems there are now people saying that vitamin D likely is more important to bones than calcium. And other sources suggesting that the upper safe limit for vitamin D is " at least five times the current official USL " , I.E. 10,000 IU as opposed to 2000. The european RDA for Ca is 700 mg/day I believe. In north America it is more like 1200. fwiw, bwdik, I am getting a total of about 1200 mg of Ca per day, having raised the amount of supplement I take recently; and perhaps 1500 IU per day of D. I do not doubt I will be doing something different yet again twelve months from now!

Guest guest Posted April 13, 2008 Report Share Posted April 13, 2008 If I am reading the test results from my onc. Which one would be my vitamin D levels is there something else it is called? I am very fair skinned and I do everything I can to stay out of the sun. I am interested in this vitamin D thing . Thanks Eva From: Malseed Sent: Sunday, April 13, 2008 3:18 AM Subject: [ ] vitamin D levels Hi Ladies, When I was dx with CML, my Vit D levels were already low and I was started on the same regime of 's, except that I only took it for 5 months after the initial weekly dose. As compounding chemists are hard to find, I now take 1,000 u/s per day and each time I have a blood test, my haem/t always checks my serum calcium and Vit D levels. Vitamin D deficiency is not usual in our sunny OZ, but I can remember several years ago, there was a report that talked about lowered Vit D levels in the European countries which caused depression over the winter months.
