Can she replace l-tyrosine with whey powder?
She didn't not have any problem with her thyroid before. The high TSH and T4 are only after taking Iodoral. The low T4 probably indicates that she needs more protein after supplementing with Iodoral. Actually, she is very health concious and eating a healthy Diet and, apart from taking the Iodine companion nutrients, she is also taking other supplements as well. She does a lot of excercises everyday.
