Try levothyroxine for suspected subclinical hypothyroidism and brain fog

IlMarco · 2025-04-16T05:17:24-0500

Good morning, having a TSH always tending to high , averaging 3.50 or 4 MicrUi/ML I am thinking of trying lavo-thyroxine and see if it solves my mental fog accompanied by confusion and poor concentration.
I was thinking of something like 25 micrograms to start , does anyone have experience? Thanks

Using t3 (6mcg twice daily) will likely alleviate your symptoms short-term but try finding the root cause of your symptoms which unfortunately could be many....
too much e2, too little dht, too little dhea, too much stress, overtraining, depression etc

I recommend measuring ft3 and ft4. Supplement with iodine and selenium before adding thyroid hormones.

Hi thank you for your reply .
My e2 and dht were quite good in the last examinations .
The dhea was also ok .

I am 38 years old and these are the values :
Dht 579.26 pg/mL 250 - 990
Estradiol 22.6 pg/mL 0.0 - 39.8
Dhea-S 188.1 ug/dL 34.5 - 568.
Just cortisol it so High :
23.92 > ug/dL 5.27 - 22.45

I try take thyrosine,zinc,selenium and iodine two months but dont work for me .
