Hi everyone ..
Whenever I take magnesium supplement or food high in magnesium, I will get hyperthyroid symptoms such as (insomnia, fast heart rate and high alertness ... ) as opposed to my usual hypothyroid symptoms. I know that magnesium increases the conversion of T4 to T3, but not sure what is exactly happening!
My diagnosis was not clear from the beginning, One doctor says, with suppressed TSH and normal T3/T4 you have (subclinical hyperthyroidism) while the other say it is secondary hypothyroidism based on all symptoms I have (low heart rate, shortness of breath ... ) I'm currently taking 100 mcg of Levothyroxine and feeling better.
For more info. on my test results, see my post: My Journey with Thyroid
