A widely used supplement, melatonin is often marketed as a natural sleep aid. However, concerns are growing about its long-term effects due to limited research and potential interactions with other health conditions. While it may help individuals with certain disorders, such as autism or Alzheimer’s disease, excessive use can lead to adverse effects like heart failure and immune system disruption. Experts recommend caution when using melatonin, particularly in children, and suggest trying behavioral changes around bedtime instead of relying on the supplement for better sleep outcomes.
