Melatonin is a hormone naturally produced by the pineal gland in the brain. It plays a crucial role in regulating sleep-wake cycles and is commonly used as a supplement to treat sleep disorders. While melatonin is generally considered safe for short-term use, it is important to be aware of potential side effects. In this article, we will discuss the top melatonin side effects that you should know about.

1. Daytime Sleepiness: One of the most common side effects of melatonin is daytime sleepiness or drowsiness. This can occur if the supplement is taken at the wrong time or in excessive amounts.

2. Headaches: Some individuals may experience headaches after taking melatonin. This side effect is usually mild and temporary, but if it persists or becomes severe, it is advisable to consult a healthcare professional.

3. Nausea and Dizziness: Melatonin can cause gastrointestinal symptoms such as nausea and dizziness in some people. These side effects are generally mild and go away on their own. However, if they persist or worsen, it is important to seek medical advice.

4. Mood Changes: In rare cases, melatonin may cause mood changes, including increased irritability, anxiety, or depression.

5. Hormonal Imbalance: Prolonged use of melatonin supplements can potentially disrupt the body’s natural production of melatonin, leading to hormonal imbalances. This can affect the menstrual cycle in women and testosterone levels in men. It is advisable to use melatonin supplements under the guidance of a healthcare professional.

While melatonin is generally safe for short-term use, it is important to be aware of the potential side effects. Daytime sleepiness, headaches, nausea, dizziness, mood changes, and hormonal imbalances are among the top melatonin side effects. It is crucial to use melatonin supplements responsibly and consult a healthcare professional if you experience any concerning symptoms.
