And it was all this one poor bloke across the Atlantic pond in the land of beef-and-kidney pie.<br />I hope and trust that he is doing well and has mended his ways.<br />I am 64, weigh 180# and have thaken 5000 IU/d for many years. my level 5 years ago was 79, and a couple of weeks ago it was 82. I get more sun than most, and would otherwise be white. Both levels were in July. Still appreciating your work.<br />John Day MD in Austin, TexasJohn Dayhttps://www.blogger.com/profile/12123174297818737132noreply@blogger.comtag:blogger.com,1999:blog-2455967162947276184.post-51073336267207635192022-08-12T11:36:05.171-07:002022-08-12T11:36:05.171-07:00This comment has been removed by the author.John Dayhttps://www.blogger.com/profile/12123174297818737132noreply@blogger.comtag:blogger.com,1999:blog-2455967162947276184.post-19034325765750323042022-07-12T06:19:17.827-07:002022-07-12T06:19:17.827-07:00Thank you David for another informative and intere...Thank you David for another informative and interesting article.<br />We in Australia saw this in the news. Breaking a leg is probably more serious but we didn't get an article on someone in the world doing that.<br />Maybe just not interesting enough.<br />And always good advice on reading the label. The only other cases of hypervitaminosis D I've read about describe people taking in the millions of IU daily - never about somone taking ten times the recommended dose. As you note, there seems more interest in warning us of danger of excess than in mentioning benefit.<br />In 1955 US Congress passed the metrification bill making it officially a metric unit country. The cost of changing speed signs was thought too high so they are still in miles today. No need to confuse people with a new unit system when the old one works just fine.<br />I've never read about calcitriol being made in other than the kidney but it makes sense as the growth in lymphatic tissue and white blood cell numbers during infection is staggering and Vitamin D may be required for the expression of nearly a quarter of our genes. Most of my text books are over 20 years old so I should expect a few ideas are out of date. But sad when official medical advice is probably based on them.<br />Thanks againGodfreyhttps://www.blogger.com/profile/09821844545005872058noreply@blogger.comtag:blogger.com,1999:blog-2455967162947276184.post-85617618330302956482022-07-11T17:26:57.519-07:002022-07-11T17:26:57.519-07:00This comment has been removed by the author.Godfreyhttps://www.blogger.com/profile/09821844545005872058noreply@blogger.comtag:blogger.com,1999:blog-2455967162947276184.post-85753684138039050482022-07-11T14:16:53.486-07:002022-07-11T14:16:53.486-07:00I'm a 69 yr old male, weigh about 135 lbs, bmi...I'm a 69 yr old male, weigh about 135 lbs, bmi slightly less than 20. I take 5000 units 4x/week in the darker months, which gives me the same blood level (~55ng/ml) as running shirtless daily in the lighter months (late april to sept at latitude 42N).Unknownhttps://www.blogger.com/profile/00872408988869434942noreply@blogger.com
