Rated 5 out of 5 by from Excellent Purchase I'm finding that this product works very well for helping me get to and stay asleep. I also think it is helping me with my mood. But, I do not find that it helps with controlling my appetite. I purchased this product for sleeping so I am very pleased with it. The 200 mg. time release is convenient because it only has to be taken once a day.

Rated 5 out of 5 by from Natrol's 5-HTP Time Release I have used this product for about five years and have had good results. I used to buy it locally until I ran across Swanson's catalog that someone had discarded at the post office. I noticed that Swanson's had the best price around so I gave it try. The order was processed the same day. I even received a confirmation email with detailed tracking information. Swanson is top notch!

Rated 4 out of 5 by from 200mg I like this product because it's 200mg. Now I only have to take 1 pill instead of 2.

Rated 5 out of 5 by from Excellent I began taking this several months ago and noticed right away how it improved my over all mood. I can tell when I haven't taken it, I feel blah, but once I take this, my mood is elevated and I feel happier. Haven't really noticed any changes in sleep or any appetitie control but I take for the mood inhancement.

Rated 5 out of 5 by from Like this product I was taking 5-HTP for sleep and it didn't help me much and it didn't help with cravings when I took it at night. One day I decided to try it in the morning instead, and it has really helped with cravings for excess food, which I've struggled with since childhood. I have also noticed I can handle stress better since taking it in the morning every day. I'm grateful and hope it keeps on working for me.

Rated 4 out of 5 by from helpful product Can be used at night with melatonin for sleep. Time release formula helps greatly. No "hangover sleepiness" during the next day. It is only part of what I take for sleep so that's why 4 leaves for effectiveness. If taken during the day, it doesn't make a person sleepy and helps raise serotonin.

Rated 4 out of 5 by from Combining this with 5mg time released melatonin, I get a good night's sleep.

Rated 5 out of 5 by from Best 5-htp you can get for such a great price. This product has helped me manage negative emotions and bad moods. This product is very effective.

Rated 5 out of 5 by from Great for those who wake too early I am a woman just ready to turn 60, and as many, I could not STAY asleep. I could get to sleep using the usual supplements, but not STAY asleep. So the Timed Release 5-htp really helps. I can now sleep 7-1/2 hours easily.

Rated 5 out of 5 by from Great product!! I love this product. Works well so far.

Rated 4 out of 5 by from I thought this product worked quite well to regulate my sleep pattern. I'm able to get to sleep a lot easier since taking it. It hasn't, however, done anything for appetite control. It deteriorates when exposed to the air/humidity so I cannot store it in my pill box along with the rest of my vitamins. The mood and sleep regulating it provides is enough for me to continue using this product.
