    better sleeps

    Posted by Reviewer2495123 on Jan 19, 2012

    I've always been a poor sleeper. This product helps me get better sleep. I take to empty stomach with 800mg magnesium every night.

    A Life-saver!

    So pleased to realise I could get Tryptophan again - I thought for years that it was no longer available. It is an excellent natural sleep aid. I recommend it to anyone who has difficulty falling asleep.

    Good product. I am trying it before 5-HTP to see if I can handle it.

    My husband is sleeping better since using this, but sometimes it doesn't work as good as another time.

    Wanted this to work

    Posted by Reviewer1052411 on Apr 19, 2010

    and it worked too well, I think. L-trypto is not for me. Did make me a bit groggy, and I slept well for a while. Woke several hours later with a crashing migraine, but an enhanced clarity I haven't experienced in a very long time. So good news/bad news.
