Sentinel Melatonin 3mg is a dietary supplement designed to support healthy sleep patterns. Each tablet contains 3mg of melatonin, a hormone that naturally regulates sleep-wake cycles in the body. Melatonin supplements may be beneficial for people experiencing occasional sleeplessness, jet lag, or those working night shifts. The 3mg dosage is a commonly recommended amount for adults. The supplement comes in tablet form in an amber bottle to protect the contents from light exposure. As with any supplement, it should be taken under the guidance of a healthcare provider, typically 30-60 minutes before bedtime.
