Steadfast Nutrition's Melatonin is a natural, non-habit-forming sleep supplement that works with the natural sleep cycle to support and promote better sleep. Melatonin is a natural hormone produced by the pineal gland in the brain after sunset, which helps one relax and get into sleep mode. Melatonin fluctuations are essential for maintaining a normal circadian rhythm which manages the natural sleep cycle, which is why melatonin is also known as the sleep hormone. Steadfast Nutrition's Melatonin is available as oral tablets, which are easy to use and convenient.}
