An excellent form of 5-HTP

Posted by Reviewer2776030 on Dec 19, 2014

No tummy upset woth this brand, and very effective. I would rather take one before bed and another during the hight IF I wake, rather than dose myself up every night with a stronger tablet. This really takes the edge off too re: mood. I have bought a few brands to try but this is my favourite.

good for sleep

Posted by 5355254441692460143 on Dec 02, 2014

Per Julia Ross's book, The Mood Cure, I'm taking this supplement for mood and sleep issues, and it has been very helpful for both. I actually cut the tablet in half to use the smallest possible dose, which is still quite effective for me: taking 1/2 in the afternoon and 1/2 before bed works well (sometimes with an additional 1/2 at bedtime). The only problem with this method is that you lose the benefit of the enteric coating. I've not had stomach issues, though. Another important point is to take this supplement away from protein for full effectiveness. Recommended!

Price is good. Can´t really tell the effects, but I only take it in synergy with Gaba and melatonin at night, can't really tell the effects.

Works but don't like the caplet

Posted by emanuela on Aug 24, 2013

It works fine, helps me relax, if anything makes me a bit drowsy afternoon to evening (I have been taking 3 a day, one after each main meal). Personally, I have been having trouble swallowing this whole, so have had to dissolve it in water. Therefore little point buying enteric coated caplets, I'd rather buy a capsule! Moreover, this caplet contains magnesium stearate which is not helpful. I wish magnesium stearate and all other useless eccipients were taken out of this and other supplements.

It works

Posted by Anna-Reviews on Apr 13, 2013

I used it only once (for insomnia & depression) - it worked, I slept very well and woke up feeling rested, also I had good mood the next day. I never used it again because I realised I don't wan't to depend on some drug, I want to cure the cause of my depression. Since then I read a lot about it and it appears that there are many things causing depression: food allergies, low thyroid, poor diet, environmental toxins, metal toxicity, candida overgrowth etc. (So far I've found out I have severe gluten allergy and I really feel better when it's not in my diet). So people my message is: do some research and don't cure only the symptoms of your depression, look deeper and find the cause, because there's always one.
