Rated 5 out of 5 by from Excellent This is a great product for me, will continue to buy.

Rated 3 out of 5 by from Good product, just not for me I was very hopeful that this would work for me. I have never taken anything like this so did not know what to expect. I took it this morning at 8 and about 10-15 minutes later was throwing up. That continued until about 11:30 am. I'm not really sure why that happened, but I will not be taking it again. It seems like most people don't have that problem so it is likely just me. I am taking rhodiola rose root right now and it does a decent job.

Rated 5 out of 5 by from Good product I have been using this for a couple of months for mood balance and am satisfied with what I consider positive results. The price is very affordable.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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).

Rated 1 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Work hours I work very demanding shifts, and this helps keep me awake. I only take it when and how much I need it.

Rated 5 out of 5 by from Wonderful Very helpful in evening out the mood. Has good calming effects. I recommend it to a lot of people.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.
Date published: 2014-08-03
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
