I've been suffering from depression for the last 10 years and this product helped me to laugh a bit. It gave me the energy that I lack for the whole of my life. Now it's easier to communicate to laugh and to do sport. I was so lethargic to do anything. But it contains wheat&gluten be carefull if you are allergic to those.

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.

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.
