Doesn't seem as potent as other tryptophan's I've used. Either their tryptophan source is not potent or they don't have the 500mg of it in each capsule as they claim.  Maybe that's why it is cheaper than the other brands.<br /><br />I use [[ASIN:B00H9Z57LQ Amazing Nutrition Amazing Formulas 1 L Tryptophan 500 Mg 120 caps - Supports Mood, Relaxation, and Restful Sleep - Supports Immune Functions]] and even though that costs a bit more but it works in a lesser number of capsules.
