Tryptophan is far superior to anything else I've tried for sleep, including strong and toxic drugs. Two grams of this plus valerian and I'm off to dreamland, awaking easily and with no "hangover." Thanks iHerb for making such great products available at the best prices to be found!

I use to take tryptophan years ago for sleep ,it allawys worked great. Recently tried Jarrow L- Trypto. Made me sleep through the night but feel druged for half the next day, I mean bad ,like poisoned. no matter what time of day I take it with or without food same result. Don't know if the formula has changed or its some change in my chemistry.
