Helps with Sleep and Mood

Posted by iHerb Customer on December 11 2017 | Verified Purchase

I used 5-htp for many years for sleep, mood and appetite control. I used a different brand that was "timed release" and found it helped with sleep in that I did not wake up as much. After a long break I have started taking this brand for sleep but I haven't yet noticed a big difference, but this is one supplement that is cumulative. As far as I can tell there are no "cons".
