    Works very well!

    I've been taking L-tryptophan by Vitamin Research Products for years. Each time I try a different brand, they don't work. I can feel the difference in my increased serotonin level while taking the Vitamin Research Products brand. I've read that Tryptophan works best if B6 and B vitamin levels are good.


      Definitely works! The company has a good reputation.


    I would recommend this item to a friend.
