Hi all!! Not sure if I am putting this is the correct forum area but immunity seemed the best. Any way, recently blood tests have shown I have very low vitamin D and my GP ( I am in the uk) put me on vitamin D supplements. I have been taking the supplements but I think they are not agreeing with me as my symptoms have felt slightly worse recently (more headaches and muscle pain) and can't think of anything else new in my life that could cause this. Then I saw this on YouTube and it made me think perhaps I shouldn't take vitamin D. According to the video Dr De Meirleir says that we tend to have high 125 Vitamin D which is a result of inflammation and the last thing you should do is give vitamin D supplements. I am not sure which vitamin D I was tested for but my suspicion is that it will be the 25 version of the Vitamin D as it is a cheaper test. He also says you should also check the ratio of 25 to 125 and in normal healthy people it will be around 1.5 or 2 but in ME he finds it much higher around 4 or 5. Not sure if my GP will do the test for 125 Vitamin D or even know all this information, especially where ME is concerned or how to treat it. Makes me wonder if I should keep taking the supplements... is it safe for me to continue? I know GP and the NHS generally know very little about this illness, so I should I trust them on this?
