Key Takeaway
Survey of 2,678 lithium supplement users finds most take lithium orotate for mood and cognitive benefits, with 74% reporting perceived improvements and a low rate of side effects.
Summary
This cross-sectional survey collected responses from 2,678 individuals who had purchased lithium as an over-the-counter supplement, primarily in the form of lithium orotate. The study aimed to characterize who uses lithium supplements, why they use them, and what their experiences have been - an area with virtually no prior research despite growing consumer interest.
The majority of respondents reported using lithium supplements for mood regulation, anxiety reduction, cognitive enhancement, or general neuroprotection. About 74% of users reported perceived benefits, with improvements in mood stability and mental clarity being the most commonly cited. Side effects were reported at a low rate and were generally mild, including gastrointestinal discomfort and headache. Most users took doses in the range of 5-20 mg of elemental lithium per day, far below psychiatric therapeutic doses.
The authors note that while these are self-reported outcomes and the survey has inherent selection bias (people who continued using lithium were more likely to respond), the findings suggest that lithium supplementation at low doses is generally well-tolerated. The study highlights a significant gap between consumer use and clinical research, calling for randomized controlled trials to validate the perceived benefits reported by supplement users.
