Long-term Melatonin Use May Increase Heart Failure Risk

A recent study suggests that long-term use of melatonin supplements may significantly increase the risk of heart failure, with users experiencing up to a 90% higher risk over five years. The findings raise safety concerns about the widespread use of melatonin for sleep, emphasizing the need for further research to establish causality and explore underlying mechanisms. Medical experts recommend consulting healthcare providers for sleep issues and considering other treatments like sleep apnea testing before using supplements.
