L-Tryptophan by Douglas Laboratories | Supports Melatonin Production and Restful Sleep | 60 Vegetarian Capsules
GUARANTEED SAFE CHECKOUT
Tryptophan, a vital amino acid, crosses the blood-brain barrier and is converted into L-5-Hydroxytryptophan (5-HTP), which in turn is converted into serotonin, an essential neurotransmitter necessary for the healthy regulation of melatonin production.* This process supports neurotransmitter health.
Our formulas are developed to support the management of cortisol, hormones, neurotransmitters, and relaxation, thereby promoting a positive outlook and restful sleep.*
For over 65 years, Douglas Laboratories has been dedicated to meeting the needs of healthcare professionals.
