RetzlerRx® 5-HTP 100 Sustained Release is a premium, physician-formulated supplement designed to support healthy mood, stress resilience, and restorative sleep. Each tablet delivers 100 mg of 5-hydroxytryptophan (5-HTP) in a sustained-release format, providing steady, consistent absorption throughout the day or night.

5-HTP is a naturally occurring amino acid and direct precursor to serotonin, the neurotransmitter that plays a vital role in regulating mood, relaxation, and sleep cycles. Unlike fast-release formulas that may spike and fade, the sustained-release delivery promotes a gentle, balanced effect for optimal results.

Whether you’re looking for the best 5-HTP supplement for stress and sleep, a doctor-formulated mood support formula, or a sustained-release serotonin booster, RetzlerRx® 5-HTP 100 SR is the trusted choice.
