It's back, and better than ever! L-Tryptophan 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 Swanson Ultra is the purest pharmaceutical-grade tryptophan on the world market. It's produced through a fermentation process from a vegetarian source, using the most precise standards for safety and quality assurance. Want to hear more?

Rated 1 out of 5 by from Tastes Horrible! I have been using this product for several years and it had no fillers. Now they add Rice Extract Blend. It tastes very bad. The after taste is also bad. You would think they would add a quality filler as not to ruin the product.

Rated 5 out of 5 by from Great for your brain and restful sleep I have been using for a few years. This is the best brand I have found. Some are cheaper and still effective, but I find that this is worth a few extra bucks.

Rated 5 out of 5 by from This product works great. I have been taking this product for about a month now and it has helped with my sleep problem. I take 2 capsules 1/2 hour before bedtime and am able to stay asleep. But if I have to get up during the night I’m able to get back to sleep promptly. I haven’t noticed any adverse effects as I have had with other products.

Rated 5 out of 5 by from Great for relaxation. All my life I have heard that L-Tryptophan was the number one amino acid for relaxation (think Thanksgiving turkey). I have been devoted to the Swanson brand for 15 years or more. Who knows if it really works, but I am not about to jinx myself. I will probably be taking this product until I no longer care about my health.
