Tried it and I had hair loss, and a loss of energy. I went back on synthroid and all was back to normal. My husband even noticed the difference.

I have been taking Synthroid for nearly 50 years and have had not problem. I have a blood test once a year to make sure I am on the correct dosage.

I have taken this medication almost all my life. Make sure you do not take any vitamins with iron or calcium with the medication. It takes several months to get this at the correct levels and is very important to keep taking at the same time each day.
