Rated 5 out of 5 by from Thank you. Not sure what it is about Swanson 5HTP, but it works better than any other brand I've tried. Thanks so much!

Rated 5 out of 5 by from 5HTP Because I'm sensitive to medicine, 50mg is perfect but hard to find. I've been using 5HTP effectively for 15 years with no unwanted side effects; sometime increase to 100mg during late Winter or severe stress. Thank you for affordable, good quality natural alternatives.

Rated 5 out of 5 by from recommend this I read about this in a men's magazine in 2011, as a 'break up pill' to help with mood, etc. I started on it and have stayed on it ever since. I'm female, 50+, and I find it keeps ma feeling 'normal', balanced, good.

Rated 5 out of 5 by from Swanson's 5-HTP I like taking this, but instead of taking it at night (since it doesn't make me drowsy), I take it in the morning to relax my active mind. It is on the high side price wise, so look for the sales and stock up.

Rated 5 out of 5 by from A Good Product I really like this product. It does what I want, balance my serotonin. And at BOGO....winning!

Rated 5 out of 5 by from Effective Used as a appetite suppressant. I found it to be very effective. However, the key is to take it 20 minutes prior to eating ON AN EMPTY stomach. This I found not so easy to do...remembering

Rated 5 out of 5 by from 5- HTPN This supplement really does work for me. I have a hard time falling asleep.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from VeryGood To me, I think it to have been effective without a side effect.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 5-HTP Helps with a combination of GABA, L-Tyrosine, 5-HTP, and Calcium/magnesium/plus D to help calm stress before bedtime.

Rated 2 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2013-03-08
Rated 4 out of 5 by from 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.
Date published: 2013-03-06
Rated 5 out of 5 by from 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.
Date published: 2013-02-22
Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2010-09-17
Rated 5 out of 5 by from 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.
Date published: 2010-05-08
Rated 5 out of 5 by from 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!!
