Rated 4.7 out of 5 by 163 reviewers.
Rated 5 out of 5 by Surprisingly Effective! This was the first time I had purchased 5-htp, and I was surprised at how much better I felt after I started using it. And this is still the best value I have seen for the dose and qty. May 25, 2016
Rated 5 out of 5 by have been using it on and off for years. Great product, very effective, you may feel the full effect within few short hours, one pill a day in the right time is all I need (for a normal day). February 20, 2016
Rated 1 out of 5 by No effect I took this for 2 weeks, in the hope to relieve sleepless nights, but it did not do anything, zero, zilch. Maybe it needs to be taken for a longer time or maybe it just does not work for everybody. November 3, 2015
Rated 3 out of 5 by Don't seem to do anything. I don't know. They don't seem to do anything. September 10, 2015
Rated 5 out of 5 by I'm so HAPPY I found this product Since I can't say what I'm using this for, I'll just say I'm so HAPPY i found 5-htp, and I'd be so very sad if I hadnt. Swanson has good quality and prices. I've been taking it for years and it's very effective. July 5, 2015
Rated 5 out of 5 by works as described This product works well for me. May 3, 2015
Rated 5 out of 5 by Work hours I work very demanding shifts, and this helps keep me awake. I only take it when and how much I need it. March 10, 2015
Rated 5 out of 5 by Wonderful Very helpful in evening out the mood. Has good calming effects. I recommend it to a lot of people. February 9, 2015
Rated 4 out of 5 by Amplifies the effect of SJW For me, it amplified the effects of St Johns Wort. It is not a miracle pill, but I think maximizes the potential of other supplements like SJW. February 1, 2015
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by good product I have only been taking for a month and seems to be working May 3, 2014
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by 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
Rated 5 out of 5 by A new believer The best 5-HTP on the market. It works. November 30, 2013
Rated 5 out of 5 by Great purchase 5htp works great at keeping my husband on an even keel. Keep up the good work! November 21, 2013
Rated 5 out of 5 by Very happy to have found this product Best product I've found for a natural sleep aid and I feel great. November 19, 2013
Rated 5 out of 5 by 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
