Melatonin is a hormone secreted by the pineal gland, regulating circadian rhythms and sleep-wake cycles. Production can decrease with age, leading to sleep disturbances.
Supplementing melatonin in older adults often improves sleep quality, which is vital for cognition, immunity, and general health. While not directly reversing aging, regular, restful sleep is fundamental to maintaining resilience and day-to-day well-being.
