Hi all, I was wondering wether you take Vit D3 and do you know your blood levels ? I have had mine tested with the private medic checks. The finger pricks were useless as they wanted you to fill a full test tube just from your finger , I found that impossible so I had book to go to my nearest hospital for a nurse to do it and the results said 80.3 Nmol I am aware of various research and books that say for MS this means it needs to be on the high side of normal . Mine is in normal range but what do you think about trying to get it to 150mnol ? The normal range in the uk is 50- 200nmol . In October 2015 I was 35 Nmol . I was never diagnosed with Ms until July 2017 but taking higher supplements probably since this year. If I was to get it on the high side of normal or 150 Nmol how long would it take and any idea rough idea on dosages ? Thanks Rachael
