It is Saving my life

Posted by iHerb Customer on Nov 03, 2017 | Verified Purchase

I needed serotonin and couldn't go to the doctor in my area so this stuff is saving me from a very bad depression. I have moderate to severe depression, and chronic fatigue and have been recommending it to my friends and blog readers. Thank you so much for making this product, it really does help me feel like I am young and alive again.

Thanks for your feedback!

A few weeks in and noticeable improvements

Posted by iHerb Customer on Oct 11, 2017 | Verified Purchase

Have been taking 1 capsule before sleep in combination with Natrol and Dopa Macuna over the course of the day. Can report a noticeable upswing in overall mood and feel like I've been sleeping a lot more deeply, waking up more refreshed each day. I haven't felt as tired as well towards the end of the day and am sleeping less but definitely getting a much deeper rest. Generally speaking, I feel more like my 'former self' and less on edge and feel much less negativity/anxiety, and much more engaged and levelled out.

Thanks for your feedback!

Jury still out...

Posted by iHerb Customer on Aug 10, 2017 | Verified Purchase

I only used the smallest amount of this product by pulling the capsule apart, and I have to say within and hour or so I felt a definite up-surge in mood, it made me feel quite talkative and perky, however I felt a down-turn the next day, so I used it some more and got the same effect, so I will give it a break and try again and just see if I get the same re-action. Perhaps this product will have a different effect on each individual and will vary a lot from person to person, so it is not black and white when it comes to reviewing it, I'm glad I didn't take a whole capsule, might have been bouncing off the walls :)

Thanks for your feedback!

Have been taking these in combination with NAC and other vitamin supplements for major depression and anxiety with great results after only 2 weeks. No side effects to date. Would recommend.

Thanks for your feedback!

Not for me

Posted by iHerb Customer on Jun 06, 2017 | Verified Purchase

Sadly this supplement, which I was trying to help with my depression symptoms, made me quite sick to my stomach. Which in turn made me more unhappy. I hope it works for others. I was disappointed.
