L-Tyrosine is also a precursor for the protective skin pigment melanin.

Great with ALCAR

Posted by mozzer on Apr 08, 2016

Tyrosine is useful for energy by itself but I really liked when combined with 2-3 grams of ALCAR. Tyrosine gives you that energy boost and ALCAR helps focus and direct it.

Wonderful product

Posted by -Peri- on Mar 15, 2016

I am hypothyroid and despite being on medication my concentration and energy levels are somewhere down the drain (in addition of being hypo I am single parent and university student which drains all my energy and then some)... But not anymore! I have used this product for a week and I can say I have noticed increase in energy and regaining my cognitive skills slowly despite being highly sceptical about this! :)

Be Careful

Posted by Reviewer2166233 on Dec 14, 2015

Feeling cold and unmotivated all the time, I thought I would give this a try, feeling something was off with my thyroid. It was a big mistake. The first couple days there was no effect at 1000 mg on an empty stomach. The third day I started feeling weird - really weird, like I was wired and high at the same time. Then I decided to go down to 500 mg. It got even worse - just a bad experience. I am getting off of it - I would rather be cold and tired. I should note I do drink caffeine and am by nature a tense person, so these may be factors. I would definitely not take this if you consume caffeine. All I know is now I have to wait to repair the issues this caused.
