Product Overview


  • Durk Pearson & Sandy Shaw's
  • Ajipure Amino Acids
  • (TryptoPure)

Serene Tranquility Night with Tryptophan is one of Durk Pearson & Sandy Shaw's new Serene Systems Designer Foods*. The tryptophan used is Ajinomoto Co., Inc.'s top-quality amino acid, as precursor to the natural production of serotonin. This product also contains melatonin to support better sleep.

Serene Sytems Designer Foods are made with delicious, all-natural flavors and an array of functional sweeteners. They also include other precursors and cofactors, including L-arginine, choline, vitamin B5, vitamin B6, L-citrulline, along with select vitamins, minerals, and other nutrients. These ingredients further enhance the efficiency with which serotonin is produced and also foster the production of nitric oxide, which acts as a natural serotonin reuptake inhibitor, thereby further improving serotonergic function. The ingredients in this product help to support better sleep.

Which formulation is for you? Because some people have low levels of an enzyme that promotes the production of serotonin from tryptophan, the 5-HTP formulations are better for them, because 5-HTP is the immediate precursor to serotonin. If you don’t have this condition, the tryptophan formulation can be used, with the added advantage that you are less likely to produce excess serotonin in certain tissues. This can cause undesirable, but minor, effects, such as stuffy nose. If you anger easily, this could be a sign that you have low levels of the enzyme referred to about and that 5-HTP formulations are for you.
