    Excellent product

    Posted by 5530645094843719476 on Oct 18, 2014

    I've used 5-htp for 5 weeks now (200mg/day) and can definitely feel the benefits. My appetite has been reduced significantly, I need less sleep (before I slept 10+ hrs a day, now a normal 7-8 hrs) and my mood has improved. This is not a magic pill of course but people like me with mild to moderate depression may benefit. No significant side effects. I had some mild stomach upset for a couple of days but it subsided quickly. Please remember that you shouldn't use 5-htp together with SSRI or SNRI drugs or MAO-inhibitors.

    Not what I expected

    Posted by Reviewer3122150 on Jul 30, 2012

    I started taking these because I was hoping to improve my mood that my husband claimed was bad all the time. These, unfortunately, made it very hard to get out of bed in the morning and once I did, I felt like I was in a fog most of the day. I decided to take them earlier in the day, before dinner, but the sleepiness and fogginess did not improve. I think this is probably a supplement for people who are really stressed out and that's not me.

    grief relief

    Posted by 5761101439668124507 on Jun 19, 2015

    My mother had become a bit screechy and over reactive to EVERYTHING after my father died. Her grief developed a nasty, angry and bitter edge. Which was all the more shocking as she is known for her kind heart. Within 4 days - she was calm and nothing stressed her out. We ran out of tablets so I decided to watch her and not tell her to check if the effect was a placebo... good grief! I couldn't reorder more fast enough! Bugger weight loss - take this for a calm and kind mind and an easier time through your grief journey.

    I am trying this 5-HTP to help with migraine cessation, depression, and better sleep. So far it has helped me with these issues.

    Ok Product

    Posted by 5649150956425648240 on Aug 09, 2012

    Taken in conjunction with Melatonin this helps me fall asleep but I still awaken numerous times through out the night and wake up in the morning feeling a little groggy. I am also concerned that when I stop taking these my sleeping patterns will actually worsen but I will see and update this review accordingly.

    5-htp works great!

    Posted by Reviewer3138446 on May 02, 2009

    I couldn't believe how well this worked! It worked wonderfully for my Fibromyalgia and Rheumatoid Arthritis. No more tightness in my shoulders and it was great for my morning stiffness.

    Good product, reasonable price

    Posted by Reviewer2218436 on Jan 13, 2009

    I have been taking 5-HTP for about five years now, on and off. It has been quite helpful, though nothing replaces a good therapist! I was taking "Dr.'s Best" up until recently, but the price dropped low on this brand, and so far it seems to be just as good.
