Good for mild-moderate depression

I definitely notice a difference when I stop taking these, have used this and other brands off and on for years. I find that I feel sort of flat when I take them though, like I'm not sad but also can't feel a range of other emotions as normal. Very odd, but during really hard and stressful times they have probably saved my life. Look into Sam E, lots of brans on this site, found it far more helpful!

Thanks for your feedback!

The product is great and does what it’s supposed to, but when me and my aunt stopped taking fluoxetine (SSRI) cold-turkey (yes I know we could have tapered off, but the issue is the same across the board), we didn’t fully realise the effects of the excess serotonin. We both started experiencing the effects of serotonin syndrome, which can be life threatening. So do your research before taking this if you plan to supplement an anti-depressant withdrawal. Our plan is to wait a full three months to ensure it is no longer in our system before taking the 5-HTP again. It’s a great product, but do your research: it’s powerful stuff.
