Bests & Worsts Reviews from Amazon

I am a psychiatric RN and this is the only sleep aid I use, need and recommend. I take 1 cap a night and about 75 minutes later my eyes become heavy and I pass out. What I like about the l-tryptophan is that it boosts serotonin and makes a two for one sleep aid and antidepressant. Of course talk to your doctor and don't mix these with prescription meds that increase serotonin and other certain meds. Most doctors are against supplements because they don't study them in school and aren't familiar with them, it's very sad. But, these work and with no side effects such as next day drowsiness. I see a lot of patients practically hung over after taking prescription sleep aids and it's hard to watch. Try these, they are strong. And, yes there was a recall in the 1980s but it was manufacturer-specific, related to bacteria used and after thorough evaluation in 2005 l-tryptophan was put back on the market in the United States and is even sold as a prescription in some parts of Europe.
