I took Tyrosine to supplement my hypothyroidism and make me not feel so tired all the time. Even with 75 mcg Levothyroxine I am a sleeping superstar. So I got this because, at 24, I figured I was more "brain tired" than physically tired.It doesn't give me WHOA energy, but, oddly I feel MORE. My emotions are stronger, happy is happier, nervous is butterflies in my stomach, frustrated is more upset. I don't mind this really. I find myself being more like the goofy high schooler I used to be, and that's nice. I sleep fine, I think I need less on and around days I take it.All in all, it's good. It didn't change my life, I don't have a Tyrosine shrine in my closet, but it works in some way or another and it's nice to be silly again :)
