Good product I like this product. I take it to help me sleep. It doesn't always work but it usually helps relax me. Sometimes I open up the capsules and pour the powder into my mouth for faster results. June 7, 2013
great product I've used this product for years and have had really good results. I don't have to use it every night, only when I have trouble sleeping. I never wake up drowsy, but come out of sleep naturally. May 30, 2012
the best for sleep this is the best product for sleep. Taken before you go to sleep, you can sleep like a baby...at first some have very vivid dreams, they do calm down after about a week, then the most needed sleep happens. July 8, 2011
Awful For some I don't doubt that this may work but for me it is terrible. It made my body ache and made me feel real scummy in general. Im not sure about the quality although I have tried other brands of tryptophan that didn't work but also didn't make my body ache or make me feel so scummy. Also, there are ingredients on the bottle in the "other ingredients" that aren't listed on this website. Had to return. June 25, 2009
Great for sleep This product works great..I have used it for the past two years whenever I have trouble sleeping. No lingering sleepiness in the morning either. May 22, 2008
