Love this item Excellent product--gives me more energy and keeps my brain feeling happier. April 30, 2012
Calmer & Less Irritable I was very pleasantly surprised at how effective this was. Within the first hour I felt considerably less irritable and much more calm. April 13, 2012
Great! Great product, great value! Highly recommend. April 5, 2012
Amazing results I'm generally very sensitive to stimulants like tea/coffee/chocolate, so the effects on other people may be very different from mine. For me, this has been a complete life saver. One pill can keep me going in high gear for 6 hours. It's an instant jolt of energy, I can feel my pulse rising a bit, and my focus improved. Tiredness fades away within minutes of use. It's so effective that sometimes I even doubt if this stuff should be legal! The thing that sets this pill apart from, say, coffee, is that I don't feel an obvious crash afterwards. My metabolism gradually lowers to a normal point instead of the normal complete exhaustion. Because of the marked physiological effects I experience, I only use it in true times of need (12 hour exam days with no sleep the night before), and have never used it consistently. Bottom line: very effective indeed! March 17, 2012
Great value - good Product I have been very pleased with this product. I felt energized and it helped me deal with mental and physical stress. And as always, Swanson provided a very competitive price. March 16, 2012
Great value The value of this product and it's effectiveness make it a regular purchase of mine. March 16, 2012
Overall Well-Being I take one pill 30 minutes before breakfast, and I have a positive mood all day. I've noticed not being stressed by trivial events. March 10, 2012
makes me feel better I felt more energy the first time I took it, like within 30 minutes. Wow was all I could think. I take it 3 times a day and it really helps with my mood. February 23, 2012
Very good product I've used this product for a long time. I've read that L-Tyrosine helps the thyroid. I always get good thyroid test results, so hopefully the product is helping! January 4, 2012
great addition to SAM-E take this with SAM-E and am very pleased with results January 3, 2012
Alert and Energized My wife takes L-Tyrosine the first thing each morning and insists that it keeps her alert and gives her energy. September 24, 2011
So much happier I started taking this about 1.5 months ago, combined with GABA. I had read that they were helpful for people who often felt agitated, irritable, impatient and just stressed. I take this in the morning and the GABA at night and boy does it work! I notice I have a lot more patience for things that used to annoy me quickly. I notice I'm not nearly as snippy or impatient, and not so quick to snap or make hasty conclusions. It feels good to not be so tightly wound. My husband and kids appreciate it too (or so I've heard...). If you're tired of feeling crabby give this a try, and maybe GABA as well. I feel like a normal and happy person! September 9, 2011
overall good I started taking this about a month ago and have noticed a small positive difference in mood and energy. June 7, 2011
Tyrosine This product works. Only wished it was offered in 100mg tablets. April 3, 2011
L-Tyrosine Great energy booster! This stuff works. Put that energy drink down and take this instead. For a quicker response open the cap on your tongue and drink it down. Try it! Great price too!! March 29, 2011
Energy! I like the added energy I feel when taking this. February 23, 2011
Good product At my age any help with mood and memory is welcome. Will continue to take this product, feeling better. February 20, 2011
Very good I take maybe one T daily for thyroid and mood support. It is very effective in combo with St. John'sWort to elivate the mood to smile again when it's raining. February 8, 2011
Works great! Keeps me alert and awake when I need it-GREAT STUFF! February 2, 2011
I could really feel a difference in my overall health when I started taking this. The quality is great and the price excellent. My mood is more positive and my appetite is more in control. It was recommended to me by my doctor to help my thyroid and mood. January 1, 2011
L tyrosine I read a lot about this stuff it makes my moods throughout the day feel less stressful. This stuff is not bad not sure if its like the other brands that I have tried. So far my mood control has been the same as it has been since I started taking tryosine so more than likely it works. December 12, 2010
Great Mood Enhancer This product is wonderful! The price is fabulous- better than I've found anywhere else. I've seen a drastic change in my mood since I started taking it. I wouldn't go without it. And an added bonus- it helps me tan better naturally :) October 31, 2010
Excellent Supplement! I waited to review this unitl I had been using it for more than a few weeks. I generally in the past havent seen results from a supplement before that time, BUT this is an exception! I have been using it for about 4 weeks, but I started seeing results after two! This provides excellent Thyriod support! I have noticed a great difference in my overall energy, mood, and digestion! The quality of the capsule is great! They are easy to swallow and dont cause digestive upset. This was my first purchase from Swanson. I discovered them in a support forum online by reccomendation of another poster and I am hooked here from now on! August 3, 2010
Good For You I take this with my natural thyroid tablet each morning. Makes me feel good. July 24, 2010
A few weeks ago, I started taking this product; I started by taking it every other day. This was for several reasons, but one main reason was because I wasn't sure how my body would react. When I first started to take it, I did experience the occasional hard stool, but that did subside over time. I now take it every day & hope that I continue to feel better in terms of my mood & emotional health. April 13, 2010
