5-Hydroxytryptophan
Enhances sleep and helps manage stress*
Thorne’s 5-HTP provides a well-absorbed form of 5-hydroxytryptophan – the direct precursor to serotonin – to naturally support mood, sleep, and appetite regulation.* By bypassing the body’s rate-limiting conversion of tryptophan to 5-HTP, this formula promotes serotonin synthesis more efficiently, even in the presence of stress or nutrient deficiencies.* It also includes pyridoxal 5’-phosphate (the active form of vitamin B6), an essential cofactor for serotonin production.* 5-HTP has been shown to reduce sugar cravings, support restful sleep, and improve mood without requiring an empty stomach for absorption.* Derived from the seeds of the African plant Griffonia simplicifolia, Thorne’s 5-HTP offers a safe, natural way to restore serotonin balance.*
