Used this for 4 days and now I possibly have myalgia

Posted by 5208602616016868114 on Jun 24, 2013

Took 1000mg before bed for 4 days and experienced severe muscular pain after about 3 days, I stopped using Tryptophan right away. Now, 10 days later and the pain persists and is continuing to get worse. Do intensive research before taking this supplement.

not sure

Posted by Reviewer3256810 on Mar 04, 2011

I'm not sure yet if Tryptophan is better or 5-HTP. Supposedly, 5 HTP is better.

good night's sleep

Posted by Reviewer1588649 on May 06, 2010

I am at that age where it is often difficult to get a good night's sleep. However, if I take one capsule of L-Tryptophan, along with Melatonin, I can get the rest I need.

Bought this to help me sleep.

Posted by Reviewer1321333 on Aug 26, 2009

Seems to be doing the job - but can't attribute the success 100% to this as I also bought some Melatonin, which is definitely working spectacularly to help me get to sleep AND make it a good night's sleep (not my usual restless, still tired when I wake up kind)

L-Tryptophan

I have used this product along with iodine drops for depression and they are awesome I think anyone who suffers from depression should seriously consider this product.
