Selen intake could reduce suicidal thoughts
A new study has found that higher selenium intake may reduce the risk of suicidal thoughts in American adults. Researchers analysed data from nearly 24,000 participants, uncovering a clear link between the mineral and mental health. The findings suggest selenium could play a role in mood regulation and emotional wellbeing.
The study, led by Li-Xing Yang and colleagues, used information from the National Health and Nutrition Examination Survey (NHANES) between 2017 and 2020. Participants with the highest selenium levels showed a 22% lower likelihood of experiencing suicidal thoughts compared to those with the lowest intake.
Selenium is known to support brain function, and previous research has tied deficiencies to mood disorders like depression. This time, the team adjusted for factors such as age, gender, and overall health—but the connection remained strong. The protective effect appeared most pronounced in women and adults aged 18 to 44. Published in the *Journal of Affective Disorders*, the study adds to growing evidence that diet may influence mental health outcomes.
The results highlight selenium’s potential role in reducing suicidal ideation, particularly among younger adults and women. While more research is needed, the findings suggest dietary selenium could be a factor in supporting mental wellbeing. Health experts may now consider its importance alongside other mood-regulating nutrients.
