Has brown rice flour I have to stop ordering this because some brilliant person decided to add brown rice flour to it. I cannot have any grains. Please, Swanson, just make smaller pills put into smaller containers rather than put total junk in it that may be allergens. December 20, 2014
Good I take this at bedtime. It seems to help quiet my racing mind. September 5, 2014
a great product to use This supplement help your mood swing. April 1, 2014
N-Acetyl L-Tyrosine I've been taking L-Tyrosine for years and decided to give this a try. I take it in the morning to help calm the mind and help me think more clear. I works for me, I do notice a difference if I forget to take it. I will continue to take it. Thanks Swanson! March 17, 2014
Swanson's N-Acetyl L-Tyrosine So far, so good. I've been taking L-Tyrosine for years, and wanted to give this a try. I take it in the morning (making sure not to take it with any other Amino Acids so they don't compete for absorption), for a better mood and to help with mental sharpness. I've been taking this version for weeks now, and have noticed a slight difference over the regular L-Tyrosine. Some people take this at bedtime, but I like it better in the morning. I will continue to try this, especially when I can get it at BOGO and stock up a little. March 10, 2014
Focused but drowsy I took one capsule a day for a couple weeks. It made me drowsy yet somehow more focused. February 24, 2014
Best This is the best NALT supplement that I have tried and the price is right. December 26, 2013
brain food great product to help brain function October 23, 2013
no effect for me Did not notice any change in energy or mood or sleep whatsoever. Perhaps because of my current regimen of supps. October 1, 2013
Great for mood and sleep These work very well for me if taken before bed or in the middle of the night if having a tough time with sleep. One of these along with an L-Theanine, a couple of Taurines and a vitamin B complex (all from Swanson) are very helpful for improving my sleep, giving me better dreams and helping me feel refreshed in the morning and energetic all day. Improves life for everyone around me when I'm not all ticked off from having a poor night's sleep. But that's just me. Everyone's different. September 1, 2013
Awesome Product! I have tried many products that claim to offer the same benefits, but NONE have worked as well as this one. It has become a daily supplement that I can't do without! July 31, 2013
nice amino acid for that mental/emotional boost. I take two a day. July 23, 2013
Great! I'm on the road to a happier life because I did the research and found the right product. Thank you Swanson! July 14, 2013
Energy Booster The N-Acetyl L-Tyrosine is an awesome energy booster that I now take every morning. For me, it's as effective as a cup of coffee in getting me motivated to "take on the day". I highly recommend it as a GREAT fatigue fighter! July 12, 2013
LOVE THIS!! THIS IS AN EXCELLENT PRODUCT WORTH BUYING. July 11, 2013
Great energy nutrient This is a great form of tyrosine to help with basic energy levels and staying power. I use this N-Acetyl-L-Tyrosine supplement along with Kelp and Swanson Triple Iodine Complex, and it is a very effective addition to my daily nutrition program. July 10, 2013
Necessary Item! My thyroid specialist recommeded this product to help my brain work better. It really helps! My brain use to be foggy, now I can think better and quicker. July 9, 2013
Boooooooooooo Nothing, zip, zero. This could have been flour and i wouldnt have expirienced anything different at any dose (1-5 pills). My only thoughts are im either a non responder or i already get an abundance of tyrosine in my diet (im big on meat). June 25, 2013
A difference! These gave me more energy! I just started taking them but noticed a difference right away. I haven't really compared prices, but the quality seems very good. Very happy with product! June 24, 2013
Positive results This product gave me surprisingly good results in the form of extra energy. March 14, 2013
Great product This product is really outstanding. I haven't tried any other brand of this supplement other than the swanson brand, so I am unable to compare. This supplement helps my memory and brain function tremendously. March 12, 2013
I am on my second bottle of N-Acetyl L-Tyrosine. Testing has shown I am low on several amino acids. I have taken supplements of the others but when I added this supplement there was a noticeable improvement. My mood has improved and so has my energy. January 27, 2013
SUPREME TYROSINE I love Tyrosine, and this extra efficient form is totally acceptable thus far with me. I have been taking L-Tyrosine since the 1970s with great results. I have been taking Swanson Premium N-Acetyl-L-Tyrosine for a short period of time. However, thus far, I like it. As usual, Swanson's prices on Amino Acids are the best. I have no trouble recommending Swanson's Premium N-Acetyl-L-Tyrosine to everyone. Who amongst us cannot use this great nutritional supplement?! - - - Especially at such a great, low price. June 29, 2012
Energy and Focus I have been taking these for over a month now and I am impressed with how these give me more energy and mental clarity. Sure can tell a difference in my mood when I don't take it. I take these in combination with thyroid glandular first thing in the morning. I switched to these after starting with a more expensive brand and I am very happy with Swanson quality. June 18, 2012
Very Good I thought I would give this a try, and I find this works very well to lift ones spririt. I will order again. My suggestion is to give it a try. I have seen positive affects on me and others in the household. November 29, 2011
