Melatonin supplements may cause morning fatigue

Medical experts are warning that melatonin supplements, particularly in gummy form, may cause morning fatigue and exhaustion in some users. Dr. Alexander Acosta notes that many melatonin gummies contain high amounts of sugar, which can trigger rapid insulin spikes followed by a sharp drop in blood sugar levels during the night. This glucose fluctuation can leave individuals feeling depleted upon waking.

Physicians also caution against long-term reliance on melatonin, as it may interfere with the body's ability to establish healthy, natural sleep hygiene. While melatonin can be useful for short-term issues like jet lag, experts recommend focusing on consistent sleep schedules and improved sleep habits rather than daily supplementation.
