About Melatonin Tablets

Melatonin Tablets contain 3 mg of melatonin, a naturally occurring hormone that helps regulate your body’s sleep-wake cycle. When travelling across multiple time zones, your internal clock can become disrupted, leading to jet lag. Melatonin supplements help restore your biological rhythm, effectively reducing symptoms such as sleep disturbances, daytime tiredness, fatigue, irritability, and digestive issues associated with travelling.

Melatonin Tablets are intended for the short-term treatment of jet lag in adults.

What Is Melatonin Used For?

Melatonin 3 mg tablets are specifically used for the short-term treatment of jet lag in adults. It assists in realigning your body’s internal biological clock, which is often disrupted by long-distance air travel, thereby relieving symptoms like daytime fatigue, sleep disruption, and mood changes.
