Investigating Recent Digital Search Trends for Melatonin and Other Sleep-Enhancing Supplements and Their Link to Usage Patterns: A Google Trends Study

This study aims to focus public attention on search terms that include melatonin and other sleep promoters based on information from the Google search engine, to analyze regional and seasonal trends and predict the public's interest in these supporters in the future." The global interest in "melatonin" and other sleep supplements was assessed through search volume analysis via the "Subject" search tool in Google Extended Trends for Health data. From December 22, 2019, to December 28, 2024, a thorough examination was carried out, targeting the keywords 'Melatonin', 'magnesium', 'zinc', 'theanine', and 'apigenin'. Data were analyzed using correlation and simple linear regression models, one-way ANOVA test, 5-year rolling mean analysis, and feature significance. Melatonin emerged as the most prevalent sleep promoter identified in global searches. The strongest relationship identified among the search terms was between magnesium and theanine, while the lowest relationship was between zinc and sleep. The year in which the moving average increased the most in the last five years was 2023. After 2023, the popularity of magnesium-sleep, zinc-sleep, melatonin-sleep, and sleep variables continued to increase, while the popularity of apigenin-sleep and theanine sleep parameters decreased. It was ascertained that the increase in theanine, melatonin, magnesium, and apigenin values in Google searches increased the sleep variable. In contrast, the decrease in these values led to a reduction in the sleep variable. It is predicted that the popularity of melatonin and magnesium will continue to increase in 2025, particularly concerning searches related to sleep.
