Great with ALCAR

Posted by mozzer on Apr 08, 2016 | Verified Purchase

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.

Thanks for your feedback!

L-Tyrosine

Am yet to begin taking Source Naturals L-Tyrosine to assist toward thyroid function and the fact that I tend to be prone to depression. Will review later.
