Guest guest Posted November 14, 2004 Report Share Posted November 14, 2004 Hi folks: " Vitamin D in Australia. Issues and recommendations. Nowson CA, Diamond TH, Pasco JA, Mason RS, Sambrook PN, Eisman JA. School of Health Sciences, Deakin University, . BACKGROUND: A significant number of Australians and people from specific groups within the community are suffering from vitamin D deficiency. It is no longer acceptable to assume that all people in Australia receive adequate vitamin D from casual exposure to sunlight. OBJECTIVE: This article provides information on causes, consequences, treatment and prevention of vitamin D deficiency in Australia. DISCUSSION: People at high risk of vitamin D deficiency include the elderly, those with skin conditions where avoidance of sunlight is required, dark skinned people (particularly women during pregnancy or if veiled) and patients with malabsorption, e.g. coeliac disease. For most people, deficiency can be prevented by 5-15 minutes exposure of face and upper limbs to sunlight 4-6 times per week. If this is not possible then a vitamin D supplement of at least 400 IU per day is recommended. In cases of established vitamin D deficiency, supplementation with 3000-5000 IU per day for at least 1 month is required to replete body stores. Increased availability of larger dose preparations of cholecalciferol would be a useful therapy in the case of severe deficiencies. PMID: 15054977 [PubMed - indexed for MEDLINE] " Rodney.

Guest guest Posted October 22, 2009 Report Share Posted October 22, 2009 There’s also a spiel on the home page urging people to join (for a fee) and getting friends and the friends getting friends etc to join (sort of a “pyramid” thing) to solve the “Vit D” deficiency epidemic. Smacks too much of religious zeal and snake oil to me. Nevertheless I am now taking 2000IU a day. So I certainly hope that Vit D is the panacea that is now all the rage in medical circles. But we’ve seen all this before with Vit C, Vit E, and other supplements which, looking back, were useless, even some harmful, in large doses.

Guest guest Posted October 23, 2009 Report Share Posted October 23, 2009 Hi Tony and Francesca: Oooops. Thank you for pointing out the apparent commercial motivations of that website. I should have taken a closer look at it before posting, and added the caveats you have both already done for me. Thanks. I have a new 25(OH)D test result to report. Previously, when supplementing 3500 IU daily, my serum level was measured to be 127 nmol/L of total (D3+D2) vitamin D. Now, after supplementing 5000 IU daily for the past six months, the new number is 150 nmol/L. That, imo, fwiw, is more than enough. So, from here on I plan to supplement 4000 IU daily and expect my serum level might drop to around 135, which is what I have been tentatively aiming at for quite some time. Of course, YMMV. So, whatever amount you supplement, have your serum level checked to make sure you are in the safe range. If taken in humungous amounts vitamin D is, of course, toxic.

Guest guest Posted October 26, 2009 Report Share Posted October 26, 2009 Hi JR: I had a B12 test in April 2009 which came in at 122, comfortably below the supposed 'low safe threshold' of 150. I asked for it to be repeated, and the repeat test, done a couple of weeks later, showed 118. I decided to treat with 1000 mcg (one thousandth of a gram) of B12 daily in the regular swallowable (i.e. NOT the sublingual) version. Six months later - a couple of weeks ago - the number was now 507. A couple of years ago, having never taken supplements of it, my number had been around 170. Above the threshold, but not by a huge amount. I do eat meat and fish. But not a lot of it. Hope this helps.

Guest guest Posted October 26, 2009 Report Share Posted October 26, 2009 yes,thanks.tests can be wrong, but the odds of two, spaced apart in time being wrong are quite low.

Guest guest Posted October 26, 2009 Report Share Posted October 26, 2009 Did you have symptoms of B12 deficiency. Anything to do with the Vit D low? Regards [ ] Re: More On Vitamin D Hi folks: I also had my B12 tested again. You may recall that about six months ago, at the other end of this very wide country, I was 'diagnosed' as appreciably deficient B12, with my metric units number coming in at around 120, compared with the 'low safe threshold' of 150. Since then I have been supplementing 1000 mcg daily. My new number (507) is almost three-and-one-half times the 'low safe threshold' number! My GP says she finds it difficult to believe, even given the supplements I was taking, that my number could go so high in just six months. Her conclusion is that I am certainly not having a problem absorbing B12, which had been assumed previously. In any event, the point that may be of interest for this group is that if you have a B12 deficiency you certainly want to know about it, and fix it, one way or another. So testing for it is desirable. My folate level was also checked. It came in at ten times the 'low safe threshold' level. I used to take one folate pill weekly. But now it looks like the fortification of bread with folate makes supplements of it redundant - at least for me. fwiw Rodney. Quote Link to comment Share on other sites More sharing options...
