Rated 5 out of 5 by from Must be dreaming...It helps! For those who's biological engine is in need of a little fine tuning...I'd say this is definitely worth trying. After marking off many other supplements due to symptomatic sensitivities or lack of benefits when I've tried them, L-Tyrosine seems to be providing me a notable difference. I'm glad I took stock in some of the other reviews in this case as the results have been positive. I've experienced some real increase in alertness & memory. I do find that I metabolize this rather quickly so some individuals might require taking dosage slightly less or more often. Please ALWAYS, safety first...Research & consult with a medical physician for any individual's needs & monitoring. Improved health = happiness!

Rated 5 out of 5 by from my staple supplement Tyrosine has changed alot of things in my life, my first purchase was with Swanson and I've never looked back. It helps with an increases in my mood, it seems to decrease my mood swings and lowers my anxiety problems. If you are in the right mindset it also makes me feel a little more motivated throughout the day. Great product, will probably be getting this for the rest of my life

Rated 5 out of 5 by from Love Swanson!!!! I have been a customer of Swanson for a long time, and I have to say I started on a new variety of supplements just a short time ago and this would have to be the best yet. I have been feeling a little better each day. When our new gym opens I will really be able to tell just how good our supplements are working. I well keep everyone updated. THanks Swanson.

Rated 5 out of 5 by from absolute favorite supplement L-tyrosine is the best thing that ever happened to me! :) Wish I knew about it a decade ago.

Rated 3 out of 5 by from Be Careful with this This supplement needs to be used with caution. It can give a rapid heartbeat, irritability and affect sleeping. It can aid in adrenal gland function, but not everyone can take it.

Rated 5 out of 5 by from l tyrosine i have used several products over the years that have L tyrosine as an ingredient. I found that the L tyrosine was the ingredient that was working for me. Now I use Swanson 500 mg L tyrosine. It helped me so much after my husband passed away, it is mood lifting, gives me extra energy, and I would recommend it to anyone. and Swanson products are very effective and the prices are excellent.
