Excelent, effective

Posted by 5321940870207759494 on Mar 04, 2017 | Verified Purchase

I take this for OCD and anxiety, it works very well and doesn't make me as sleepy as 5-HTP. Because it has to be converted to 5-HTP by the body, the onset is about 2 to 3 hours from taking it, preferably on an empty stomach. When it kicks in, you notice a mild relaxing effect that peaks for about 1-2 hours and then fades away within 8 hours aprox.. I recommend taking it with L-Theanine for a more accentuated relaxing effect. Don't take too much, just 1 pill in the evening/night or 1 pill in the morning and 1 in the night.

Unbroken sleep

Posted by 5064732123726214674 on Feb 16, 2017 | Verified Purchase

Helps our sleep to be unbroken. And seems to help a lot with anxiety. We have a break for a month or two, between using up the bottle, as we don't seem to need to take it continuously, and our body's seem to prefer that.

L-Tryptophan to Boost Serotonin

Posted by 5551472729331789816 on Feb 06, 2017 | Verified Purchase

I was experiencing anxiety so i decided to take l-tryptophan. Funnily enough my brain fog disappeared so it was good for that. But i found that it kind of made me feel a little too sedate. So ive decided to discontinue from using it. Not saying its a bad product, it just didnt work for me :(
