Works better than standard L-tyrosine

Posted by iHerb Customer on Sep 29, 2008 | Verified Purchase

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

Thanks for your feedback!

Source Naturals, N-Acetyl L-Tyrosine, 300 mg, 120 Tablets (SNS-00217)

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.

Thanks for your feedback!

Great Supplemental Drug

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

Not happy

Posted by danarm on Dec 01, 2012 | Verified Purchase

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.

Thanks for your feedback!

A great way to get L-Tyrosine

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

Thanks for your feedback!

Excellent Source of Tyrosine

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

Thanks for your feedback!

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

Thanks for your feedback!
