The N-Acetyl Tyrosine seems to work better than L-Tyrosine, and at a much smaller dose. This particular brand seems to do well.

You can always rely on Source Naturals for product integrity. Over the last two months, upon the advice of my neuologist,I have been taking (2) 300 mg tabs daily, to increase serotonin production for mood enhancement. Personally, I have not seen the results that others claim, but its not to say that is doesn't work for most people.

I love using this product as a way to adjust my dosage of L-Tyrosine intake. I use this product to supplement the medicine for my hypothyroid condition. The recommended dosage of one pill is not quite enough for my body's needs. I like adding it to my daily routine when I have a need for more than normal. - Dallasite

In theory this is a better version of l-thyrosine. In practice, it doesn't have the same energy, mood and motivation effects on me. I also don't like that the pills are sour and acidic. I will stick to the plain l-thyrosine that I know and love.

This the N-Acetyl form of the Tyrosine means a small tablet and better absorption for mood support. I like it!

Best absorbtion of Tyrosine I have tried. Great absorbtion makes up for low mg.

My husband uses this product on a daily basis. He feels it helps him maintain chemical messangers in the nervous system.
