Melatonin · 1 mg

Melatonin helps signal the body's sleep timing and may shorten the time it takes to fall asleep. The 1 mg in one serving provides the product's sleep-related contribution. Its effect depends on administration timing and individual sleep timing; the amount does not establish a universal optimal dose or treatment benefit for chronic insomnia.

Melatonin's connection to stress relief is limited to sleep-associated situations and certain procedural anxiety settings. That doesn't mean it will ease everyday psychological stress or lower cortisol. Its role here is narrow, so the serving amount alone isn't a reason to expect broader calmness.
