Description
"Melatonin" is a hormone synthesized by the pineal gland that regulates sleep-wake cycles. Responsive to light exposure, its production increases at night to promote restful sleep. Its antioxidant properties extend to cellular protection and immune support. Beyond sleep regulation, melatonin influences cardiovascular health and blood pressure control. Supplementing with melatonin is common for jet lag, insomnia, and circadian rhythm imbalances. Recognized for its neuroprotective effects, melatonin remains an important factor in sleep health and overall well-being.
