  • TryptoPure L-Tryptophan from Doctor's A-Z

  • 100% pure pharmaceutical-grade L-tryptophan supplement

  • An effective, natural sleep support supplement

L-Tryptophan is more than a punchline to a Thanksgiving Day joke about eating too much turkey. It is a precursor to serotonin, and it's powerfully effective when used properly. By supporting serotonin levels, L-tryptophan not only helps us fall asleep and stay asleep, but it also promotes mental health and provides dietary support against nervousness and tension. TryptoPure L-Tryptophan from Doctor's A-Z is the purest tryptophan—and the only pharmaceutical-grade tryptophan—on the world market. It's produced through a natural fermentation process from a vegetarian source, using the most precise standards for safety and quality assurance.

Customer Ratings & Reviews

TryptoPure Pharmaceutical Grade L-Tryptophan 3 5 1 1
Great product, too costly While pharma grade tryptophan is a fantastic product for sleep, I prefer the powder form (not in capsules) mixed in a smoothy with enhancing B-6 and Lysine. I find the pharma grade Doctors Best TryptoPure for about half the price per mg compared to this Doctors A-Z. July 26, 2011
