Product education

L-Tryptophan by Douglas Laboratories

L-Tryptophan is an essential amino acid that serves as a precursor for serotonin synthesis, promoting a sense of calmness and restful sleep. This dietary supplement is designed for adults seeking to enhance their mood and regulate appetite through the natural production of serotonin. With its ability to cross the blood-brain barrier, L-Tryptophan is converted into L-5-hydroxytryptophan (5-HTP) and subsequently into serotonin, a vital neurotransmitter.*

Key Benefits

  • Supports serotonin production*
  • Promotes restful sleep*
  • Helps regulate mood and appetite*

How It Works / Key Ingredients
