Made me nervous and jittery

Posted by Reviewer2107594 on Apr 10, 2016

Did not help me relax and got my body all tense and tired due to a bigger lack of sleep after consuming this product.

Used this for many years - a God send

Posted by AIM-FOR-GOOD-HEALTH on Mar 15, 2016

5-HTP gives you tryptophan what the body needs to produce its own serotonin which enables you to fall asleep. As we age (or reach menopause), we produce much less serotonin and for many sleep becomes a problem. Great supplement, great brand and highly effective solution for insomnia. My advice is to take it immediately before getting into bed otherwise your brain will get the message that you want to stay awake and will take action to counter its effects - that's been my experience of some 20 years of using this. In the end I fully resolved my issue by addressing over-stressed adrenals (which is often a big factor in today's society and for women in menopause especially when symptoms go on for years). I took the herb Schizandra for my adrenals - miracle stuff. I am now cured of Chronic fatigue and insomnia after 9 years of searching for a solution to my sleep issues.

Just re-ordered a 2nd bottle

Will never be without this now. Best natural sleep aid. And I have tried St John's wort, melatonin which I hate as it gives me nightmares and makes me feel sluggish and irritable when I wake up. Valerian, and nothing seems to work except chemical sleeping pills which are addictive and mind numbing. Now I am sleeping pill free and can even sleep without 5HTP after 6 months of use. Great stuff and evens out my mood the next day.

Bought this to help with anxiety problem but ended up with serotonin syndrome : rapid heart rate, heavy sweating, shivering. Stop taking.

No significant effect

Posted by Trinity on Feb 23, 2014

I haven't noticed any significant effect of this product so far. I still wake up quite a few times during the night.

ineffective brand for me

Posted by Reviewer1733570 on Feb 14, 2014

5HTP reliably gives me a quick mood boost, a real saver many times as I'm often low in serotonin. Unfortunately I saw no benefits from this product in particular though I appreciate Now Foods. Best results I've had with Natrol Time Release.
