Welcome to the forum

Well you need to give some more info

How much levothyroxine are you currently taking, how long on this dose and do you always get same brand

Same question for T3

Do you have autoimmune thyroid disease

When were vitamin D, folate, ferritin and B12 last tested

What vitamin supplements are you currently taking

Are you dairy or gluten free

Please add most recent thyroid and vitamin results and ranges

Always test as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

Day before test split T3 dose into 3 smaller doses spread through the day, taking last 1/3rd of daily dose approx 8-12 hours before test

I take 100mcg of t4 and 5mcg of t3 three times a day . Not dairy or gluten free , but low ferritin from donating blood because on testosterone. My t3 free is 2.8 pg/ml free t4 1.2 ng/ml, vitamin d is 88 ng/ml have not checked b12. Thanks so much for any help, when working out even moderate my heart rate increases to near 120.
