5-HTP 100 Sustained Release | Mood, Stress & Sleep Support
Support balanced mood, stress resilience, and restorative sleep with RetzlerRx® 5-HTP 100 Sustained Release, a physician-formulated supplement designed to promote serotonin production and steady neurotransmitter support.* Each tablet delivers 100 mg of 5-hydroxytryptophan (5-HTP) in a sustained-release format for gradual, consistent absorption.
5-HTP is a naturally occurring amino acid and direct precursor to serotonin, a neurotransmitter involved in mood regulation, relaxation, and sleep-wake balance.* Unlike fast-release formulas that may peak quickly, sustained-release delivery is designed to provide a gentler and more consistent effect over time.
