My Vit D levels were 30.9nmol/l back in June, and I was prescribed 20,000IU weekly for 6 weeks, and I have then reverted to 3,000IU per day (GP suggested 800IU but after reading your website I opted for a 3,000IU spray). I was retested at the end of August, and my levels are now 71.2nmol/l – which is classed as "normal" within the UK. I still suffer with fatigue (serum ferritin also low and am taking three iron tablets a day). I have continued taking the Vit D3 spray of 3,000IU daily. My first question is – should I continue this dosage long term? The GP will not retest my levels as they are now within normal limits (above 50nmol/l is the cut-off).
My next question concerns my children who are 16, 13 and 10 years. My 10 year old weighs 37Kg. I have been giving them 3,000IU daily, and I just want to check that I am not overdosing them at this dosage? They do not have any diagnosed deficiency, although my eldest has suffered with low mood and fatigue (but could be normal for teenager!). I also give them Omega 3 fish oil capsules which contact DHA & EPA – not sure if this is relevant?
Thank you for your help.
