Understanding Melatonin Overdose Risk Factors and Causes
Melatonin, a hormone that regulates sleep-wake cycles, has gained popularity as a supplement for insomnia and other sleep disorders. While generally considered safe, taking too much melatonin can lead to overdose and adverse effects. In this article, we will explore the risk factors and causes of melatonin overdose, symptoms to look out for, and prevention measures.

- Lack of medical supervision: Consuming melatonin without consulting a healthcare professional can result in potentially hazardous overdose.
- Pharmaceutical interactions: Other medications or substances can interact with melatonin, increasing the risk of overdose and adverse effects.
