Seemed good but possible headache

Posted by Reviewer2331736 on Feb 29, 2012

I took these for about a week and felt more alert and focused, however, on the 7th day I got a horrible headache. Not sure if it was this or the L-Theanine I was taking at the same time. Discontinued both and the headache didn't return. I may try this again by itself. Like the tablets instead of capsules, as I can't take capsules. Thanks!

Mood Elivator

Posted by Reviewer1177787 on Mar 05, 2010

I use Tyrosine to boost my mood. A single 500mg dose is noticable several hrs later. It also helps with energy.

L-Tyrozine

Posted by Reviewer2594691 on Feb 24, 2009

Suppose to be good for you, but one of the side effects is break outs - HATE THEM. I'm breaking out worse then a teenager. Had to stop taking it.
