    helps with sleep and anxiety

    Posted by Reviewer2729859 on Nov 08, 2009

    I've being using L-Tropraphan for 2years now. I've suffer from Panic disorder for the past 25 years. The L-Tryptophan has been a gerat help with alleviating my anxyety and also helps me have a more relaxed sleep. I have had no hesitation recommending this product to friends and family who suffer with similar problems

    This does help me sleep. I use it along with complete amino acid mixture for help with my fibromyalgia.

    Product works fast, but doesn't last all night. I get about 4 hours sleep, then am wide awake.

    I only used it once and found it ineffective so I didn't try it again.

    Not too impressed

    Posted by Reviewer1602926 on Apr 23, 2010

    I am sure this is a high quality form of Tryptophan based on the brand. However, I ordered it because of all the promise Tryptophan supposedly holds as being very helpful for insomnia. This did not help me with my lack of sleep, and when I pop one at any time of the day, (empty stomach)I really can't tell that I have taken anything period. On the other hand, 5-htp sends me into another world but also does not help my sleep. These supplements are tricky, I think that in most instances you are better off taking Rx as you can at least count on a degree of consistentcy in how they actually perform.

    This helps with sleep and also take 10mg of melatonin..per night...this works for me (mood)...I also take amitryptaline for a sleep disorder brought on by another drug thru medical conspiracy.

    I have been on the anti-depressant Wellbutrin for two years and decided I did not want to put up with the side effects any longer. After much research I decided to go off the WB and try L-Tryptophan. I wasn't sure if it would really work, but to my suprise and relief it has been working excellent. I sleep great and feel better than I did on the WB. I take on capsule at night before bed.
