In one study, artificially aged mice treated with melatonin had reduced oxidative stress and markers of cerebral aging and neurodegeneration, indicating the melatonin offered both neuroprotective and anti-aging effects.2 In another study, researchers revealed that combining daily exercise with the daily intake of melatonin appeared to have a synergistic effect against brain deterioration in mice with Alzheimer's disease-associated mutations.3 Improvements in behavior, learning and memory were noted. Melatonin's immediate precursor is the neurotransmitter serotonin, which is a major player in regulating and giving a lift to your mood. And, like serotonin, melatonin plays important roles in your physical and mental health. Studies have shown that insufficient melatonin production can set you up for:
