Guest guest Posted January 31, 2008 Report Share Posted January 31, 2008 Great find, Bill! Thanks. I was thinking of Vit D supplementation but decided against it. I live in sunny AZ and have my blinds open to let sun in during the day so I think I get enough from that. After reading this, I am really not going to risk it.

Guest guest Posted February 1, 2008 Report Share Posted February 1, 2008 Hi Bill Thanks for this info.I do not have medical background and could not clearly understand what is said below. Does that mean it stimulates the adrenals? is this study on vit D or vit D3?(I can not watch the video as I have problem with my pc).What does display cortisol from GCR means? I had noticed that vit D3 was increasing my temp. so I had been taking it regularly at 1000 I.u dosage. I am wondering what could be effect of using long term regular vit D3 on adrenals and/or thyroids? My last flu came after injection of high dose vit D3 so I am also wondering the effect of high dose of D3? bw Nil Re: Possible that high dose of vit D causing spike in temp High vitamin D tends to cause hypothyroidism and hypoadrenalism: Prof Trevor Marshall's AAEM 2006 Presentation - Part 2 of 2 SEE VIDEO: http://www.youtube.com/watch?v=ZMn-zUTTHgw 25-D and 1,25-D both compete for the Glucocorticoid receptor (GCR) . have very high affinity for the adrenal axis . displace cortisol from GCR . both CRH and ACTH are downregulated . and this produces adrenal insufficiency Vitamin D also competed for the alpha Thyroid receptors . 1,25-D competes with T3 for the alpha thyroid receptors . at high concentrations this stops the receptors from working . and this produces hypothyroidism Quote Link to comment Share on other sites More sharing options...

Guest guest Posted February 2, 2008 Report Share Posted February 2, 2008 Yes, Dr. Oz explained this on Oprah and it is supposedly in epidemic proportions in the African American community so Oprah said she was now taking Vitamin D. I know for a light skinned person 15 minutes in the sun a day is supposed to be enough. I didn't know this about folic acid. So, I wonder how much someone whose skin tone is in between would need? My community is predominately Hispanic and I guess it would be some where in between if a person has a medium brown tone. Cheri -----Original Message----- The darker your skin the more vitamin D supplements you have to take, because your are designed to prevent an overdose of vitamin D and a deficiency of folic acid, from your ancestors having lived in very sunny climates. The lighter your skin the more folic acid you have to take especially if pregnant to avoid neural tube defects and the less vitamin D you need to supplement with if you get even a few minutes of natural sunlight. I don't remember how but I do remember reading somehow dark skin prevents the body from needing quite so much folic acid. But lighter skin is designed to prevent our cold living ancestors from developing Vitamin D deficiencies. Please don't think my saying this makes me some kind of racist. I'm whiter than sour cream but would be dead without Drew and divorced and living in poverty without the civil rights movement. We really do all need each other. Hensley .
