Excellent mood normalizer at a great price

Posted by 5322249426383897036 on Oct 18, 2016

It is a small pill and easy to swallow. I started taking this for better sleep and within 5 days I was sleeping 8+ hours and dreaming again. Take together with Melatonin.

A brighter perspective!

This has without doubt lifted me up. I wasn't depressed but just didn't feel up to being sociable, creative or happy. It's definitely helped, I feel better in dealing with daily chores,,rude people & cooking for my family.

Yes and no

Pros: It is doing what it is supposed to be - it is making me calm and with no worries, day goes by perfect. Cons" terrible stomach ache plus heartburn. I am sensitive to 5htp. I thought this one having delayed release will make a difference. After one pill it took me 3 days of Ulcetrol and Glutamine to fix my stomach back to normal. For some reason it is like drinking acid; I don't want to take another pill, but if I will be desperate I will try taking it with Losec.

Elevated mood.

Posted by 5064430644097743672 on Jun 30, 2016

My 11 yo son has depression and is undergoing therapy, these have had a fabulous effect on him, (he started on a 50mg dose) I even checked it wasn't a placebo thing as I switched them with a multi vitamin and his mood fell dramatically. I highly recommend this, but if it's for a child you need to talk to your GP first.
