I take L-Tyrosine with my doctor's recommendations. My TSH was high, and this product helped it to go down in a month. Then I had a month without taking L-Tyrosine, and my TSH went higher again. So, in my case it is not a magic pill that can decide my problem. But it works nicely and fast.

This supplement changed my life. I am not big on medications prescribed by Dr's. In fact, I refuse to go on medication. However, I made the decision that if this did not work I would consider medication. Three days into taking it, I felt the difference. I felt lighthearted and every day has been a good day since taking it.
It's more convenient to wake up in the morning! amazing. I've been worried for a long time about how bad I feel because I can't get up in the morning, but that's already been resolved. I wish we had met earlier. I take it in the evening before bed and feel the effect in the morning. Thank you.
