Sentinel Melatonin 5mg is a dietary supplement containing 60 tablets designed to support healthy sleep patterns. Each tablet provides a 5mg dose of melatonin, a hormone that helps regulate the body's natural sleep-wake cycle and may assist with occasional sleeplessness. Melatonin is a hormone naturally produced by the pineal gland that helps regulate circadian rhythms and sleep patterns. As a supplement, it may be beneficial for people experiencing jet lag, shift work sleep disorder, or difficulty falling asleep. The 5mg dosage is considered a moderate to strong dose. The supplement comes in a sealed amber bottle to protect the contents from light and moisture. As with any supplement, consult with a healthcare provider before use, especially if pregnant, nursing, taking medications or have a medical condition.
