Isn’t melatonin bad/habit forming

Our formula isn’t habit forming because we use a microdose of melatonin at .3mg. The body needs low levels of Melatonin to regulate circadian rhythm.
Higher dose supplements with 1–5mg put you out of the natural range, flooding brain receptors and creating up to 100x more Melatonin in your blood. This is what causes the hangover. Our microdose of Phytomelatonin keeps you in the natural range without the grogginess.
