Aims and Scope
The International Journal of Tryptophan Research is an international, open access, peer reviewed journal which covers all subjects related to Tryptophan research. There is no suitable journal that focuses on Tryptophan, and the IJTR aims to fill this void and provide a forum for those with interests in this area.
The journal also covers related precursors and metabolites such as serotonin, melatonin, niacin, tryptamine, kynurenine, and indoleamine 2,3-dioxygenase. Topics include isolation, functionality, interactions, analysis, synthesis and industrial production, as well as supplementation and role in diet, physiology, neurological disorders and immune response. However all articles related to Tryptophan are welcome.

Manuscript Types and Preparation Guidelines
Information on manuscript types accepted for peer review and guidelines for manuscript preparation is available here. A template manuscript, sample manuscript, and pre-submission check list is available here.
All articles are subject to blind independent single-peer review by expert reviewers. Editorial decisions are made by Editors-in-Chief or Associate Editors. The editorial process from peer review to first editorial decision takes three to four weeks following acceptance of each paper for peer review.
In the open access business model many editorial decisions result in a fee payment to the publisher. Because of this we maintain a strict distinction between editorial decisions, made by Editors-in-Chief or Associate Editors, and business decisions. SAGE Publishing does not make nor attempt to influence editorial decisions. Editorial decision makers receive no incentives to make decisions leading to fee payments.
The journal is committed to high standards of integrity. Authors are required to confirm their compliance with ethical and legal requirements upon submission. Prior to publication all authors must provide signed confirmation of compliance. Where concerns arise the journal will apply the Committee on Publication Ethics guidelines on ethical matters.
