Hi I've been having low thyroid problems for over a year now. The highest my tsh has ever been Is 5.7,but my t4 and t3 have always been optimal. I've been tested for hashimotos twice and both came back negative. The doctors don't know what's causing my thyroid to stop working properly. Last year I took multivitamins as I felt it may have been a nutritional problem and after 3 weeks my tsh came down to 2.1 and all of my symptoms disappeared. So I stopped the vitamins and after a month it went back up to 5.1. I tried taking the vitamins again but they didn't work. So for the last few months I've been searching for the specific vitamin that could be causing my problems. I just had my serum magnesium tested (I know this isn't the best test but it was all I could get on the nhs) and it came back at 0.77 which from what I've read is pretty low,and to be honest since only 1% of mg is in your blood I'm probably very deficient. I've had a look online at mg deficiency and hypothyroidism and there does appear to be a link. Has anyone heard of this or experienced this before?
Thanks in advance.
I don't have a range (I forgot to ask) however I've copied this from Wikipedia......
Normal magnesium levels in humans fall between 1.5 - 2.5 mg/dL. Usually a serum level less than 0.7 mmol/L is used as reference for hypomagnesemia
One more thing to add: the multivitamins I was taking only had 27% of my RDA for mg,I've read online that if you have a severe deficiency multivitamins will only work a little bit ( this could be why they didn't work the second time) has anyone heard of this?
