I use to take these before bed so it only made me sleep longer and have vivid dream but not necessarily good sleep and that's it. When I tried it in during the day it gave me really bad anxiety and made me really jittery. I stopped it and tried it after few days, and again it gave me a really bad anxiety that lasted for few hours. I didn't have any anxiety for almost a year and before I would have mild anxiety occasionally but not often. I'm 30 years old female and quite healthy. Wanted to take this to help me be calmer. It seemed like it worked for others so I would recommend buying a small bottle to check it out. Only good thing is that it didn't cause any GI discomfort. Please click YES, if my review was helpful, also check out my other honest reviews on other products. Cheers!

Thanks for your feedback!

It works

Great 5-HTP with no stomach upset. With other brands with no enteric coated i get a lot side effects. I use it before sleep with others ...

Thanks for your feedback!

An excellent form of 5-HTP

Posted by iHerb Customer on December 19 2014 | Verified Purchase

No tummy upset woth this brand, and very effective. I would rather take one before bed and another during the hight IF I wake, rather than dose myself up every night with a stronger tablet. This really takes the edge off too re: mood. I have bought a few brands to try but this is my favourite.

Thanks for your feedback!

good for sleep

Per Julia Ross's book, The Mood Cure, I'm taking this supplement for mood and sleep issues, and it has been very helpful for both. I actually cut the tablet in half to use the smallest possible dose, which is still quite effective for me: taking 1/2 in the afternoon and 1/2 before bed works well (sometimes with an additional 1/2 at bedtime). The only problem with this method is that you lose the benefit of the enteric coating. I've not had stomach issues, though. Another important point is to take this supplement away from protein for full effectiveness. Recommended!

Thanks for your feedback!

Price is good. Can´t really tell the effects, but I only take it in synergy with Gaba and melatonin at night, can't really tell the effects.
