My favorite supplement A great supplement and the one I wouldn't do without! Too bad I cant share the reasons I take this supplement because its better than anything else! I recommend you research this supplement for yourself and see the great things about it! I buy from Swanson because I trust their quality and you cant beat their prices! Best of health to you! November 24, 2014
Works really really really well Yeah 5-HTP makes me feel almost uphoric. Love this stuff. I use it in combination with Lithium Orotate. Works well. September 16, 2014
5 htp This product has been amazing in regards to my mood being stabilized and my sleep. The price is excellent, and unlike medications, if I miss a night I don't suffer. Definitely recommend this product! August 25, 2014
Good For Focus I bought Swanson's Extra-Strength 5-HTP for stress relief. It is effective for that but I found that taking a lower dose(50mg) worked well for me and I felt more mentally focused taking it. Too high a dose made me too relaxed, sleepy. August 3, 2014
Stress Buster The salutary effects of 5-HTP are almost immediate, especially when needed during particularly stressful conditions such as meeting crushing deadlines at work. And the Swanson caps go down very easily without any stomach upset. August 1, 2014
Great Product I added this supplement to my regime during a very stressful time in our lives. It helps us get the restorative sleep I need to get through each day. I recommend this supplement. I take it along with glycine. May 22, 2014
good product I have only been taking for a month and seems to be working May 3, 2014
Great Stuff! Works so well to moderate moods. Used by 55 , 68 and 86 year olds in our house for tranquility and uplifting emotions. Great stuff. March 28, 2014
Good for sleep I like this. It mellows me out and prepares me for a good nights sleep. It is understood to be a precurser to seratonin which helps to prolong the deep stages of sleep. I lasts for about six hours, so the last two-three hours of sleep can have an REM rebound affect which seem to produce calm dreams in the early morning. February 15, 2014
Best SLEEP While pregnant I had a really hard time sleeping. Either not soundly or long enough. Once I started taking this product at night before bed I could sleep so good!! And the price is outstanding!!! December 30, 2013
All Good My Doctor told me to start taking this product and I have used this ever since. I am grateful for having yet another Swanson brand product I can count on! December 19, 2013
usefull I read about this product some where else and went to Swnsons to read about it there/.I bought it and will continue to use it. I feel mentally healthier using this product. December 4, 2013

best, cheapest 5 HTP for your buck This is as high quality as others I've tried, and is much cheaper than you can usually find. That's all I need--sweet (and interesting!) dreams! November 13, 2013
good product Great for improving mood and for sleep quality. I definitely noticed a difference when taken daily (at night) with my overall ability to handle stress throughout the day. October 17, 2013
Took two for sleep issues and it worked pretty well. I think the enteric coated version works a bit better though. September 29, 2013
It works 5-htp is great for raising serotonin levels and helps me sleep. I read somewhere though, that it may take up to 3 months for it to be fully effective. I haven't yet reached that stage so am patiently waiting. September 24, 2013
5 htp - natural alt to ssri Natural seratonin works better for me than anything else I tried without any negative effects. Great product at a great price. September 6, 2013

Great product, great price! This is by far the most economical source of 5-HTP I've found anywhere. I find that it helps support healthy moods. August 8, 2013
