L-Tryptophan 5 5 3 4
It Works My husband and I have a lot of trouble sleeping and this product has made a big difference for us. When he awakes in the middle of the night and can't return to sleep, he takes 500 mg. and fall back to sleep within 30 minutes. It makes me fall asleep at bedtime and helps to keep me asleep.
