University of Redlands Students Study Effects of Melatonin Products

Now, in summer 2024, Olson, along with biology majors Vanessa Sherman and Kathy Bonilla, is researching the bubble bath alongside a melatonin-infused lotion and an oral pill. This study is a continuation of Olson’s prior research conducted between 2021 and 2023, which is set to be published in an upcoming issue of Neuroendocrinology Letters. The research is part of the University of Redlands’ Student Science Research program, designed for students to engage in meaningful research alongside faculty for ten weeks during the summer.

Participants will either take an oral supplement, soak their feet in the bubble bath, or apply the lotion. "We’re taking saliva samples for 48 hours afterward to analyze participants' melatonin levels," Olson explained. The research aims to identify which treatment raises melatonin levels most effectively and which maintains elevated levels the longest.

Vanessa, who chose Redlands for its small class sizes, expressed excitement about the research opportunity. "This is something I’ve been waiting four years for," she said, emphasizing the value of sharing progress with peers in other projects. Her involvement is expected to prepare her for a potential career in research.

Kathy, a first-generation college student attracted to biology's medical ties, echoed similar aspirations of pursuing research post-graduation. "Some of my favorite parts of this project are running the treatments on myself and understanding the participant experience," she stated, noting her learning about the Enzyme-Linked Immunosorbent Assay (ELISA) for analyzing saliva samples.

Both students recognize the study's significance for melatonin consumers. Kathy pointed out potential misconceptions about the safety of melatonin in lotion form compared to pills, noting a need for clarity about dosage and usage. Results from Olson’s previous research indicated that melatonin levels in participants using the lotion increased approximately 1000-fold compared to a placebo.

“This project will provide insight into melatonin levels and any associated side effects for its consumers,” Vanessa added, highlighting the intention to enhance understanding of the effectiveness and safety of melatonin products for mental and physical health.

What began as Olson’s duty to investigate her doubts has evolved into a substantial study involving engaged students at U of R. Olson emphasized the importance of consumer awareness, particularly regarding the lack of instructions on the bubble bath’s usage. “This is important to get out there so that consumers can be cautious, especially when using it on kids,” she stated. The study aims to help inform consumers about safe melatonin use.
