Potential Heart Risks Linked to Long-Term Melatonin Use

New preliminary research suggests that long-term use of melatonin supplements may be associated with an increased risk of heart failure and higher mortality, raising concerns about its safety beyond short-term use. The study analyzed health records from over 130,000 adults and found significant associations, though limitations in methodology mean further research is needed. Despite its popularity and general safety for short-term use, these findings highlight the importance of cautious long-term consumption and further investigation into melatonin's effects.
