Works for me
I've had on and off depression for 5 years now. It was a little over a year ago that the depression came back along with anxiety and for over a year now I've been having constant depression + anxiety and for anyone that experiences daily 'body low' feelings along with chest tightness, it's unbearable and very stressful on the mind + body. I chose not to go on antidepressants years ago, even when it was highly suggested by doctors that I start taking antidepressants I refused. I decided to give St Johns Wort a try and that did help but I had to stop taking it, due to complications. I decided to give 5-htp a shot and first tried the NOW FOODS brand after hearing / reading so many positive reviews about 5-htp itself and I tried it for over a month and my friend also tried it with me but we both experienced the same effects... up moods followed by comedowns. I didn't want to give up on 5htp as I really wanted to believe that it did work, like it did for many others. I started taking this brand for a month and started to notice the effects after a few weeks. I was able to handle my emotions much better and the anxiety / depression lifted and it was so so relieving to finally feel 'normal' again after dealing with terrible daily anxiety / depression for over a year, untreated. A few weeks ago I started skipping the the 5-htp, due to forgetting and probably feeling too good to realize that I still needed it. Quite unexpectedly, I started to feel anxious again and the depression came back and I was confused and feeling like I did before, a feeling I didn't want to experience again. I started taking the 5-htp immediately and after a few days I lost the anxiety and depression and now I am feeling calm. I don't usually write reviews but from my experience, I really want others to give this product a try if they are wondering whether they should or not. The NOW FOODS brand did absolutely nothing for me, but this works wonders and I can't tell you how good it feels to feel calm and to have a positive outlook. If this brand doesn't work for you, try another brand. But I can say that this brand is excellent, and works for ME. Life changing.

Deep sleep and no weird dreams!

Posted by 5131886271797156678 on Oct 03, 2016

I started taking this after weaning myself off of antidepressants (SSRIs) and so far so good. I take one before going to bed and also take 3mg melatonin. Works great, I sleep well, if kids wake me during the night I fall back asleep quickly. I feel like I got a great night's rest and can function well the next day. One added bonus - no more weird dreams that antidepressants caused. But I still clench my teeth during the night.

Helps Me Deal with PMS and Stress!

Posted by mirindalikethedrink on Sep 23, 2016

After I had a really bad bout with PMS, I asked my Naturopath what she suggested and on her list was taking 5-HTP. This product really does help! And I've grown fond of a lot of Jarrow products. Great quality and very effective.

Relaxing sleep worth every cent

Posted by Allinstar on Aug 09, 2016

I use to wake up 5-6 times every night. Since I started using Jarrow 5-HTP I have a very relaxing sleep and wake up with loads of energy every morning. This product is highly recommended!
