The best product I have ever taken!

Posted by Reviewer1656749 on Jun 12, 2008

I used to suffer from clinical depression, however, for years I didn't respond to any of the conventional medications. After a long research I learned about 5HTP and I have been taking it on and off for 15 years now. I don't suffer from chronic depression anymore but every once in a while I might get an episode here and there, and when that happens I take 5HTP. I take 50mg 1hr before I go to bed with a glass of water (from all the research I have done it's not recommended to have milk because it might interfere with the absorption). From my research it is recommended a person starts taking 50mg for 5 days then if needed go up to 100mg. I have always taken 50mg; it has worked the best for me. I'm not a doctor, but I am a person that knows quite well what it means to suffer from depression for many, many years and when all medications failed, 5HTP always helped me. And the best part is that it's all natural and you see results immediately. Many blessings to you on your journey to recovery. claudia

Great product!

Posted by Reviewer1834949 on Sep 11, 2010

I bought 5HTP to calm my nerves and hopefully get a decent night sleep. Ar first, I was confused whether to take it at night or in the morning. After trying both times, I discovered it was best to take at night, get a great night sleep and still be somewhat calm during the following day. The bonus is it stopped my nervous eating habits.

Great for serotonin-related depression

Posted by Reviewer2575097 on Jan 13, 2012

Works nearly as good as the Effexor antidepressant that I used to take. You need to take a break from it now and then, I usually take 2 days off a week. It makes me much less hostile towards other people and more lighthearted, good for self-confidence as well. If you're taking it long-term, you usually need to balance it out with something for dopamine like L-Tyrosine in the morning as well though as dopamine and serotonin balance each other out in the body. Otherwise you may make your dopamine low which may make you feel depressed, tired or spacey. So if your depression is caused by low dopamine and not low serotonin, this may make you feel worse. As long as you know how to take it properly, it's a great supplement. To make it work properly, you should take a Vitamin B complex or a multivitamin in the morning as well.

5-htp - Good Stuff!

Posted by Reviewer2913460 on Sep 20, 2009

I decided to stop using Prozac & my friend said I could use 5-htp instead. I just started the 5-htp & already I have no more debilitating headaches. Also, I'm starting to shed the unwanted pounds I gained from the Prozac. I know I must be patient to give the 5-htp more time to really get into my system, but I feel like it will take care of the depression without the side effects I experienced with Prozac. I'm grateful to my friend for letting me know about 5-htp. iHerb.com sends their products out in a very timely manner, as well.

htp is awesome

Posted by Reviewer3157278 on Mar 29, 2008

5-htp is great for hot flashes (menopause), depression symptoms, mood enhancement, etc. I highly recommend it. I know of people who have weaned themselves from anti-depressants and are now taking htp with no side effects. They are very pleased with the results.
