5- HTPN This supplement really does work for me. I have a hard time falling asleep. March 4, 2014
5HTP - don't like to be without it! Works well to calm and relax. Like the 50mg size--better to take smaller doses over the course of the day. January 17, 2014
VeryGood To me, I think it to have been effective without a side effect. September 8, 2013
Sleeping better Saw a broadcast that recommended 5-HTP for a good night's sleep. Knew that the best price would be Swanson. Tried it and LOVE it. Thanks. August 31, 2013
Great product! I bought this to help with my PMS cravings and my overall mood. I feel more energetic and have a much more pleasant demeanor since I've started taking this. August 22, 2013
love my 5HTP Since my husband and I have been taking 5HTP every morning before breakfast, we've noticed a difference in our moods. We both seem to be more upbeat about daily life. We would highly recommend it to anyone. August 7, 2013
My husband takes this to help him sleep and it works great! July 29, 2013
Best Purchase Ever This item works very well and fast, just wish I knew about it sooner, I am much calmer now and more peaceful, and the price is very fair. July 18, 2013
Small capsules Since my son has to take this twice a day for his weight, I like that the capsules are so small-easier for him to swallow. April 11, 2013
5-HTP Helps with a combination of GABA, L-Tyrosine, 5-HTP, and Calcium/magnesium/plus D to help calm stress before bedtime. March 31, 2013
Not sure yet I have had no success with this yet but i've only been into it a month. I'll try one more month and hopefully I will see and feel something. March 8, 2013
sleeping better I have been taking this product for about a month now. I haven't seen any help with losing weight but I do notice that I am sleeping much better. A more sound sleep and not waking as much during the night. March 8, 2013
Helps me sleep Started to take this and now I am back to sleeping eight hours a night. All you have to do is follow the directions and make sure you get enough exercise. March 6, 2013
Swanson 5HTP I like Swanson 5HTP because it helps me sleep at night. I don't always eat foods that help me sleep so I take 5HTP. February 22, 2013
Love this product You just have to try it for yourself to see the results you will get from taking this product. I have taken this for years and it is the best on the market. February 24, 2012
NO GOOD FOR ME!! I am sure this helps some people a lot, but for me, it was the WRONG thing. I felt worse when I took this, nervous, anxious, irritable, crazy dreams. But the great news is that I am now taking Swanson's St. John's Wort, and I feel better than I have felt in years, with NO side effects. November 16, 2010
It does the job. It does what it is supposed to do, as well as any brand I've used, and that's about 4 or 5 brands. September 17, 2010
best for the least price I've taken many 5-HTP's, some at multiples of the price Swanson has, and this one worked for me very well...just as I wanted. May 8, 2010
A Must For Me!! I take this every night about an hour before I go to bed. I also take cal/mag and GABA with the 50mg of 5HTP and I sure notice a difference if I don't have this product!! January 3, 2010
Terrific mood enhancer This guy makes me feel like everything's going to be ok (which it is), without drowsiness or insomnia. I usually had to choose between these two side effects, among others, with those other pills. Natural supplements, where have you been all my life? Nevermind, I'm glad you're here now.
