I have had an under active thyroid for many years, I’ve recently learns about T4 and T3 tests. All mine have come back as “normal”. I have read about amino acids which can help you, I eat healthy, exercise 3 times a week and I’m no spring chicken. I never loose weight and when attending medial appointments the Doctors take one look at me and say it’s life style, loose weight eat healthy.
Please can anyone shed light on whether these supplements help. Thank you
