5-hydroxytryptophan and Creatine for Treatment Resistant Depression Associated With Hypoxia in Females

Completed · Phase 4

Conditions studied: Major Depressive Disorder

In brief

The investigators hypothesize that the administration of two widely available, naturally occurring dietary supplements, 5 hydroxytryptophan and creatine monohydrate, will reduce the severity of depression in individuals exposed to chronic hypoxia by living at altitude. The purpose of this study is to determine if 8 weeks of dietary augmentation with oral 5 g creatine daily and 100 mg 5-HTP twice daily reduces hypoxia-related depressive symptoms measured by the 17-item Hamilton Depression Rating Scale (HAM-D) in women with SSRI or SNRI-resistant depression.
